Ha ha. Then, 13.8 billion years ago, the universe was a small speck, where everything was much closer to each other. That soccer ball is approximately the size of the Universe we see today at the moment of its birth. Also,Sergio, no just no. One theory for how our universe will end is known as the Big Crunch. One theory for how our universe will end is known as the Big Crunch. There are several theories that have been suggested over the years to try and explain what may have happened before the Big Bang, although none have been proven yet. In the first period, the universe grew from an almost infinitely small point to nearly an octillion (that's a 1 followed by 27 zeros) times that in size in less than a trillionth of a second.. versus the age of the Universe (x-axis, in years) on logarithmic scales. and then, at some moment, after expanding like this for an indeterminate, possibly very long or even infinite, amount of time, that inflationary field decayed. But is it possible that something could have existed before the Big Bang? what the size of your observable Universe is at any moment in the past or future. Some do it very slowly, while others do it very fast. According to the theory of inflation, the Universe: which triggered and began the hot Big Bang. This is the Big Bang theory. The success of this idea lies in experimentation. extrapolate our Universe back to a singularity. ball, ten years ago, represented approximately the minimum size that the Universe was at the moment of its birth. How can the universe be at least 46 billion light years across but only 14 billion years old? In an effort to find some characteristic that can separate inflation from other theories, the team began by identifying the defining property of the various theories the evolution of the size of the primordial universe. I was drawn in for decades after my science degree. As we run the clock backwards, the Universe gets smaller, but there is a limit. These and other pre-eminent questions, whose implications go far beyond the boundaries of physics and even of science, lie at the forefront of today's research in theoretical particle physics and cosmology. But if anyone still cant keep patience , can contact me at my email or phone no but with a promise to not to reveal anything about the theory till we officially release it .Regards.

Multiple infinities and imaginary numbers and neuron stars. What Is an Atomic Clock? We can only run the clock back a certain, finite amount until the story changes, with todays observable Universe and all the matter and energy within it allowed to be no smaller than the wingspan of a typical human teenager. Also this false faith erases God and teaches people they all evolved from a rock and the universe is billions of years old. In our Universe, if we want to know anything about either what it will do in the future or what it was doing in the past, we need to understand the rules and laws that govern it. You might think of the Universe as infinite, and quite honestly, it might truly be infinite, but we dont think well ever know for sure. Because for most research, it doesn't really matter. Thank you folks for the sensible follow up and thoughts based on the article. And because theres a very well-specified relationship between matter-and-energy and space-and-time the exact thing Einsteins General Relativity gives us we can use this information to figure out all the different combinations of all the different forms of matter-and-energy present in the Universe today. Many future galaxy surveys, such as US-lead LSST, Europeans Euclid, and the newly approved project by NASA, SphereX, are expected to provide high-quality data that can be used toward the goal. According to Live Science, it is possible that all that existed before the Big Bang was just dense, hot material that randomly exploded into our universe, but there isn't much we can do with that. The Universe has not existed forever. No evidence from you, no new believers for you. This transformation from inflationary energy into matter and radiation represents an abrupt change in the expansion and properties of the Universe. what its redshift is, or how much its light has shifted from an inertial frame-of-rest. This logarithmic view of the Universe shows our solar system, the galaxy, the cosmic web, and the [+] limits of what's observable out to a distance of 46.1 billion light-years away. While it is certainly possible that something existed before the Big Bang, it most likely wasn't as interesting as we might think. crumbling and releasing energy represents the conversion of energy into particles, which occurs at the end of inflation. For physicists like the late Steven Hawking, studying the moments immediately after the Big Bang are much more important for understanding physics. Its ####ing horse####! The Big-Bang theory states that our Universe came into existence from an immensely dense and infinitely hot point called the singularity, where all the matter we see today was compacted into this small . What Was Before The Universe? where it became cold and empty, except for the energy inherent to the inflationary field. And there they were. NASA, ESA, R. Windhorst, S. Cohen, and M. Mechtley (ASU), R. OConnell (UVa), P. McCarthy (Carnegie Obs), N. Hathi (UC Riverside), R. Ryan (UC Davis), & H. Yan (tOSU), The Hercules galaxy cluster showcases a great. Nonetheless, at any given time, theres a limit to how far away we can see: a limit to the observable Universe. The fact that the fluctuations are much, much smaller than that, by about a factor of ~30,000, tells us that the Universe could not have been born arbitrarily hot. Stop everyday some bs article comes out about more Bs they made up on a cpu model what a joke. light years away in the distant Universe. But for the first few. So i request you all to keep patience for just a few months to witness the greatest day in the history of mankind . Again, this is theobservable Universe; the true size of the Universe is surely much bigger than what we can see, but we dont know by how much. Did time have a beginning? Then, when was big bang? The contribution of gravitational waves left over from inflation to the B-mode polarization of the [+] Cosmic Microwave background has a known shape, but its amplitude is dependent on the specific model of inflation. It's a theory that explains the initial conditions for the Big Bang. It was a black hole in a state of critical mass! This transformation from inflationary energy into matter and radiation represents an abrupt change in the expansion and properties of the Universe. <p>Cover has some rubbing and edgewear. "Inflation tells us that the period of time before the Big Bang was extremely cold, almost at absolute . We have found the Answers to Everything and it will be the ULTIMATE THEORY OF EVERYTHING !! But early on, they move close to the speed of light, meaning they behave like radiation, which not only dilutes as the volume grows, but also loses energy as its wavelength stretches. In a flash of intense heat and light, the beginning of everything that has ever existed in the universe came into being. Meanwhile, please stop polluting comment threads with worthless opinion. To help decide between inflation and these other ideas, the issue of falsifiability that is, whether a theory can be tested to potentially show it is false has inevitably arisen. You cant have it both ways. However, there is a limit to that extrapolation, as going all the way back to a singularity creates puzzles we cannot answer. the size of a soccer ball! Created in association with the American Museum of Natural History. In the first period, the universe grew from an almost infinitely small point to nearly an octillion (that's a 1 followed by 27 zeros) times that in size in less than a trillionth of a second. These fluctuations, which get stretched across the Universe in inflation, should be of a slightly different magnitude on small scales versus large ones. Ha ha ha ha. When we go back as far as we know how to go, everything is consistent with this idea. These came into existence around one ten-thousandth of a second after the. The first long-lived matter particles of any kind were protons and neutrons, which together make up the atomic nucleus. He believes this process could happen indefinitely, with universes continually creating parallel universes eternally. This is where the problem lies. In other words, the Big Bang is not an explosion in space, but rather an expansion of space. You know, beyond reasonable doubtaThe fact is that scientists have kicked few cans out of the way, and that is haunting modern world of physics. The Universe we have is not only governed by Einsteins General Relativity, but a special case of it: where the Universe is both: If the Universe is the same in terms of matter-and-energy in all places and in all directions, then we can derive a Universe that must either expand or contract. If we imagine all of the information we learned so far about what happened before the Big Bang is in a roll of film frames, then the standard clock tells us how these frames should be played, Chen explained. "Before the Big Bang" would be, by definition, outside of our universe. matter and dark energy ratios in the Universe today. limits of what's observable out to a distance of 46.1 billion light-years away. Generally speaking, most physicists don't look much into what happened before the Big Bang. For most of the first 9 billion years of the Universe's history, matter -- in the combined form of normal and dark matter -- was the dominant component of the Universe. Then, in a trillionth of a trillionth of a trillionth of a second, it exploded outward, doubling and re-doubling and re-doubling in size at a rate faster than the speed of light in a phenomenon physicists call inflation. kicks a soccer ball with an Iraqi child. Well? the standard model assumes that the generations are all the time reversible, however that might not be the case in the very first stage of an early universe.That needs to be proven, too! Before the universe Gods Spirit hoovered over the darkness (space) . All five forms are present, but different components dominate at different times. What was there before the universe appeared? The study will appear in Physical Review Letters as an Editors Suggestion. And these theories are impossible to verify for certain without a time machine or magical crystal ball. Its hard to understand your argument when youre only complaining about someone elses but not offering any substatiating counter-claims. The mean temperature of the Universe was more than 2 million Kelvin. Even with impressive current technology, the furthest the Hubble Space Telescopewas able to see was an object 12.9 billion light years away. Their goal is to give insight into a long-standing question: what was the universe like before the Big Bang? This universal explosion gave birth to the first elementary particles, which then formed stars and galaxies. This image shows a slice of the matter distribution in the Universe as simulated by the GiggleZ [+] complement to the WiggleZ survey. That range has been improved with the capabilities of the James Webb space telescope, which (per Time) can see 13.6 billion light years. We like to extrapolate our Universe back to a singularity, but inflation takes the need for that completely away. Chago Zapata. I bring these up because these different components, radiation, matter and dark energy, all affect the expansion of the Universe differently. components in the Universe at various times in the past. If you see a supernova go off in a distant galaxy, youassume that you know how intrinsically bright that supernova was based on the nearby supernovae that youve seen, but you also assume that the environments in which that supernova went off was similar, the supernova itself was similar, and that there was nothing in between you and the supernova that changed the signal youre receiving. From the reviews: What happens to the big bang singularity within string theory? (It could still have been much larger, like the size of a city block or even a small city, for example. He regularly appears on TV and podcasts, including "Ask a. The creation of something new is not accomplished by the intellect but by the play instinct acting from inner necessity. The stars and galaxies we see today didn't always exist, and the farther back we go, the closer to [+] an apparent singularity the Universe gets, as we go to hotter, denser, and more uniform states. that you know how intrinsically bright that supernova was based on the nearby supernovae that youve seen, but you also assume that the environments in which that supernova went off was similar, the supernova itself was similar, and that there was nothing in between you and the supernova that changed the signal youre receiving. ESO/INAF-VST/OmegaCAM. At some point around 200 to 500 million years, the earliest generations of stars and galaxies form (exact timings are still being researched), and early large structures gradually emerge, drawn to the foam-like dark matter filaments which have already begun to draw together throughout the universe. Even though we know that the Universe is 46.1 billion light years in any direction today, we need to know theexact combination of what we have at each epoch in the past to calculate how big it was at any given time. This theory, based on Einstein's Theory of General Relativity, states that our universe's current expansion will eventually slow to a halt. We evolved chemically on one of the exploded bits of the firecracker like Tony mites we see on our world. Currently, scientists don't know what the universe was like at any point before one second after the Big Bang (via Live Science). I laugh at you. There must have been a cutoff to how far back we can extrapolate that our Universe was filled with matter-and-radiation, and instead there must have been a phase of the Universe that preceded and set up the hot Big Bang. [2] The instant immediately following the initial singularity is part of the Planck epoch, the earliest period of time . Where there is no universe, no time, no causes or effects, not even . concentration of galaxies many hundreds of millions of light years away. I should add, that said it is nice if the fringe group come up with better experiments. when matter (normal and dark, combined) began dominating radiation in the Universe, the Universe was about ~10,000 years old, and about 10 million light-years in radius. This theory, based on Einstein's Theory of General Relativity, states that our universe's current expansion will eventually slow to a halt. No matter what value people measure for some observable attribute, there are always some models of inflation that can explain it.. For most of the first 9 billion years of the Universes history, matter in the combined form of normal and dark matter was the dominant component of the Universe. What Scientists Think The Universe Was Like Before The Big Bang. The size of the Universe (y-axis) versus the age of the Universe (x-axis) on logarithmic scales. We have already started to search for these signals and there are some interesting candidates already, but we need more data.. When the Universe was onesecond old, it was too hot to form stable nuclei; protons and neutrons were in a sea of hot plasma. If we can answer that question, we can learn how far back we can extrapolate the Universe we have today, and can learn what its minimum size as close as we can get to the birth of what we know as our Universe must have been. How far will scientist go in the wrong direction to make their theories work. But for the first few thousand years, radiation (in the form of photons and neutrinos) was even more important than matter! As Einstein wrote: For we convinced physicists, the distinction between past, present, and future is only a stubbornly persistent illusion. two different techniques astronomers use to measure the expansion of space at various times/distances in the past. So, how hot did the Universe get at the hottest part of the hot Big Bang? However, to be accurate we should mention the Source of the Big Bang happened before the big bang. Once we measure and prove exactly what happened at Big Bang, it will collapse universes wave function and the universe as we know it will disappear. One can continue to extrapolate this forwards and backwards in time, but only so long as the components of energy that exist today didn't have transitional points. Free shipping. Judging merely by the illustration, the universe appears to be FM. All the way back to a singularity? But earlier, the Universe was dominated by matter, where it grew at a particular rate, and even before that, it was dominated by radiation, where it grew at still a different rate. If a pattern of signals representing a contracting universe were found, it would falsify the entire inflationary theory, Xianyu said. But if the Universe emerged from a singular high-energy state like that, there would have been consequences for our Universe: consequences that run counter to what we actually observe. The moments that happened before all of this, however, are still a mystery to physicists. The initial singularity is a singularity predicted by some models of the Big Bang theory to have existed before the Big Bang [1] and thought to have contained all the energy and spacetime of the Universe. No one can possibly have as poor grammar and lack of sense as you have displayed. For most of the first 9 billion years of the Universe's history, matter in the combined form of normal and dark matter was the dominant component of the Universe. U.S. Marine Corps photo by Gunnery Sgt. For most of the Universes history, these have been the only five components that mattered. Surprisingly, it doesnt give us a singularity, where the Universe reaches infinite densities and temperatures at an infinitesimal size. One can continue to extrapolate this forwards and backwards in time, but only so long as the components of energy that exist today didn't have transitional points. Opinions expressed by Forbes Contributors are their own. We can even plot this out: given how much time occurred since the hot Big Bang, how large was the size of the observable Universe? The primordial universe was not entirely uniform. The Universe couldnt have been much smaller than that, since the constraints we have from the Cosmic Microwave Background (the smallness of the fluctuations) rule that out. If you allow your Universe to get too hot, early on, you would see that it created an energetic spectrum of gravitational waves. Their goal is to give insight into a long-standing question: what was the universe like before the Big Bang? Instead of a bang, the Big Bounce theory views the creation of the current universe as a double funnel with a previous universe shrinking into the tiny connecting middle, passing through the "bounce" and then expanding again into a new universe. It is the least likely of all possibilities. According to Carroll, this theory works similarly to how radioactive particles decay. and how big it appears to be, or how many angular degrees it takes up on the sky. when the Universe was only about 100,000 light-years in diameter, roughly the size of the Milky Way galaxy, the Universe was only ~3 years old. document.getElementById("ak_js_1").setAttribute("value",(new Date()).getTime()); SciTechDaily: Home of the best science and technology news since 1998. Save my name, email, and website in this browser for the next time I comment. All Rights Reserved. The fact that it drops in energy density faster than matter means it gets relatively less and less important as time goes on. we can determine how much of the Universe was dominated by any different form of energy we care to look at: normal matter, dark matter, dark energy, neutrinos, and radiation. As you can see, dark energy may be important today, but this is a very recent development. Cutting-edge space missions take us back 13.8 billion years to the very beginning - the origin of the Universe. But what the big-bang theory is? The creative mind plays with the objects it loves. -Carl Jung. And the Deep Space Atomic Clock? Today, when you look out in any direction as far as the laws of physics allow us to see, the limits of whats observable extend to truly astronomical distances. This is the primary source of information physicists rely on to learn about what happened before the Big Bang. But whether it as a Big Bang or a Big Bounce, the question of what existed before our present universe remains an open question. Theyre like clergymen trying to explain the trinity. But i cant reveal my theory for atleast next 8 months because its being peer reviewed and moreover its being submitted for detailed analysis and experimental verification by esteemed scientists / physicists . According to NASA, the object, nicknamed Earendel, was seen by Hubble as it looked when the universe was only 7% of its current age. Did time start with this big bang too? Neutrinos: at just 0.1% of the Universe, neutrinos are interesting because theyre very light. how bright it appears to be, or how much light we can measure from the object at our great distance. My God this is a lame excuse for a science article. But to others, this is a feature that highlights the fundamental limits of not only whats known, but whats knowable. Not if your trying to tell me that right away there were 10 million galaxies. As you can see, there are a series of remarkable milestones. A Short History of Nearly Everything What is the origin of the universe? converting almost all of that energy into matter and radiation. As we run the clock backwards, the Universe gets smaller, but there is a limit. Thanks to the Big Bang the fact that the Universe had a birthday, or that we can only go back a finite amount of time and the fact that the speed of light is finite, were limited in how much of the Universe we can see. The relative importance of different energy. This view is only accessible to us today, 13.8 billion years after the start of the hot Big Bang. No matter what value people measure for some observable attribute, there are always some models of inflation that can explain it.. If youre the next Einstein, why are you well known and why dont you know how to form complete sentences with correct grammar? #Cosmology Science writer, astrophysicist, science communicator & NASA columnist. So outside of our universe, time has no meaning. While the Big Crunch isn't the only theory for how the universe will end, it just might be the key to figuring out what might have taken place before the Big Bang. Today, 13.8 billion years after the Big Bang, the Universe is 46.1 billion light-years in radius in all directions from our vantage point. The history of the Universe, as far back as we can. The Universe couldnt have been much smaller than that, since the constraints we have from the Cosmic Microwave Background (the smallness of the fluctuations) rule that out. So, we wanted to find what the observable attributes are that can be directly linked to that defining property.. Multicolored Meteors And Orions Belt At Its Best: The Night Sky This Week, Panama Fossils Help Unlock Mystery Of How Frogs Got Their Form, In Photos: NASAs Orion Spacecraft Returns After Epic Mission Beyond The Moon, Where A White Christmas Is Most Likely, And Not, In 2022, A Psychologist Teaches Us How To Rise Above The Holiday Family Drama, Webb Telescope Finds Earliest Galaxies Yet Close To The Big Dipper, How Ukrainians Are Surviving A Cold Winter Under Russias Missile Barrage, corresponds to distances that exceed 13.8 billion light-years, Friedmann-Lematre-Robertson-Walker (FLRW) metric, the maximum temperature the Universe achieved. But if were talking about theobservable Universe, and we know were only able to access somewhere between the last 10-30 and 10-35 seconds of inflation before the Big Bang happens, then we know the observable Universe is between17 centimeters(for the 10-35 second version) and168 meters (for the 10-30 second version) in size at the start of the hot, dense state we call the Big Bang. According to NASA, the James Webb telescope, launched December 25, 2021 (per Space.com), will be able to see as far back as just 100 million to 250 million years after the Big Bang. As to Sergio, I promote you to Tin Hat General. They made it up to balance the equations to promote their theories. When this happens, the universe will fall in on itself due to gravity (via Universe Today). This also means that if we went back to any point in the distant past, our Universe would also have a finite, quantifiable size: smaller than it is today, dependent on how much time has passed since the hot Big Bang. Always a pleasure to listen to intelligent and learned people. Today, it's approximately the size of the child in the photo, as the bounds have shifted due to improved observational constraints. And my theory is not just an idea like other models , every bit of my theory is testable and can be verified experimentally . It starts with a bang! Hospital Corpsmen 3rd Class Tarren C. Windham. As my theory is in contention for this years NOBEL PRIZE IN PHYSICS i am ethically bound to not to publish it before that . If provided, your email will not be published or shared. Instead, theres a limit: a smallest possible size that the Universe could have had. The big bang also goes against the Laws of Thermodynamics, stop proposing this made up weird assumption as science. The idea that we are bouncing back and forth between bangs and crunches is not the only theory that could explain what took place before the Big Bang. Whenever that time happens to be, where inflation ends and the Big Bang begins, thats when we need to know the size of the Universe. Sifting Out Gravitational Waves From Just After the Big Bang to Understand the Conditions of the Early Universe, Scientists Propose a New Method to Probe the Evolutionary History of the Universe, You Dont Want To See What Comes Up When You Flush a Public Restroom Toilet, Messy Death Spiral: New Webb Space Telescope Images Reveal a Stars Murder Scene, Study Shows Brains With More Vitamin D Function Better, Columbia University Obesity Treatment: Nanotechnology Reduces Fat at Targeted Locations, 20 Times Larger Than the Milky Way: Large Atomic Gas Structure Discovered, Challenging the Prevailing View 45,000-Year-Old Ancient DNA Reveals Hidden Human History. 52 Likes, 6 Comments - Facts | Life Hacks (@incomparablefacts) on Instagram: "The biggest mystery concerning the history of our universe is what happened before the big bang." That phase was theorized back in the early 1980s, before these details of the cosmic microwave background were ever measured, and is known as cosmic inflation. Cosmic inflation sets up this initial state. So how big was the Universe when it was first born? According to the European Council for Nuclear Research, just a few minutes later, protons and neutrons combined, creating the nuclei of the first atoms. Around 13.82 billion years ago, matter, energy, space - and time - erupted into being in a fireball called the Big Bang. Lets get real with this. There would be no limit to how far back you could run your equations, or how far you could extrapolate this line of thinking. The Future of Black Hole Images is Bright. Ha ha. I think too many things are being taken for granted. In some of these theories, the state of the universe preceding the Big Bang the so-called primordial universe was contracting instead of expanding, and the Big Bang was thus a part of a Big Bounce. Heres why that limit exists, and how we can figure out the minimum size of the early Universe. The Big Bounce would make a departure from western civilization's view of reality since St. Augustine, because it would recognize that time actually existed before the universe as we know it. [+] Some size and time milestones are marked, as appropriate. The Big Bang: Before the Dawn: Directed by Ashley Gething. It expanded and, from the cooling debris, there congealed galaxies - islands of stars of which our Milky Way is one among about two trillion. But can we go back arbitrarily far? Stepping backwards: when matter (normal and. Some scientists have theorized that if the Big Crunch were to occur, it is possible that all that matter being smashed into one place could create enough energy to trigger a second Big Bang, restarting the universe from scratch (via Space.com). The universe is currently 13.7 billion years old, but the time when radiation and matter contributed equally to the density of the universe was about 50,000 years after the big bang. According to the generally accepted Big Bang Theory, the Universe was formed from an infinitely dense, tiny ball of matter. The large-scale structure of the Universe grew from a more uniform, hotter, denser state, and only occurred as the Universe gravitated, expanded and cooled. was or will be at any point in the past or future. The diameter of the Milky Way is 100,000 light years; the observable Universe had this as its radius when it was approximately 3 years old. You dont need an observatory like LIGO to see it; it would imprint itself in the polarization signal on the cosmic microwave background. was once dominated by a large amount of energy. Surprises me how any real theories can explain the universe before it became the universe. And there are other ideas. Such particles should exist in any theory and their positions should oscillate at some regular frequency, much like the ticking of a clocks pendulum. The most prominent theory which explains the birth of the Universe is the Big Bang theory. To some, thats a bug, demanding an explanation all its own. Why? Heres what that looks like. A team of scientists has proposed a powerful new test for inflation, the theory that the universe dramatically expanded in size in a fleeting fraction of a second right before the Big Bang. The primordial Universe was not entirely uniform. In the meantime, theoretical physicists will continue to study the complex math surrounding those crucial first moments in order to better our understanding of how our universe was created, and what may have been around before it. Top: Big Bounce. Moreover, by measuring their redshifts, we can learn how much the Universe has expanded over the time the light has traveled to us. Here are some fun milestones, going back in time, that you may appreciate: If we want to, we can go back even farther, of course, to when inflation first came to an end, giving rise to the hot Big Bang. Today, 13.8 billion years after the Big Bang, the Universe is 46.1 billion light-years in radius in all directions from our vantage point. Astronomers call these three classes effects evolution (if older/more distant objects are intrinsically different), environmental (if the locations of these objects differ significantly from where we think they are) and extinction (if something like dust blocks the light) effects, in addition to the effects we may not even know are at play. If you can measure or determine whats in your Universe, then these equations will tell you all about your Universes properties in both the past and the future. It was a push of energy from a non physical dimension into absolute space to create a physical dimension. After millennia of searching, we had it: an origin for the Universe! As new space gets created in the expanding Universe, the dark energy density remains constant. @Sergio, AE: No. But has it been been conclusively proved yet? For the Universe, and in particular for how the fabric of the Universe evolves with time, those rules are set forth by our theory of gravity: Einsteins General Relativity. Our best limits, from the Sloan Digital Sky Survey and the Planck satellite, tell us that if the Universe does curve back in on itself and close, the part we can see is so indistinguishable from uncurved that it much be at least 250 times the radius of the observable part. Any smaller than that, and wed see fluctuations in the Big Bangs leftover glow that simply arent there. But for the first few. There is big blast universe has time limit ,start from big blast and end at critical merge point. Now, a team of scientists led by the CfAs Xingang Chen, along with Loeb, and Zhong-Zhi Xianyu of the Physics Department of Harvard University, have applied an idea they call a primordial standard clock to the non-inflationary theories, and laid out a method that may be used to falsify inflation experimentally. The Universe Before the Big Bang: Cosmolo- 3540744193, Gasperini, hardcover, new. We are connected to the lasttiny fraction of a second of inflation, somewhere between 10-30 and 10-35 seconds worth of it. Dark matter? Some of the galaxies are really, really old and from before this big bang. One of them is that the temperature fluctuations in the Big Bangs leftover glow what we see today as the Cosmic Microwave Background radiation would have been as large as the ratio of the maximum energy achieved to the Planck scale, the latter of which is around ~1019 GeV in terms of energy. According toHawking, time did not exist before the Big Bang, so there wasn't a before. Without any clock information, we dont know if the film should be played forward or backward, fast or slow, just like we are not sure if the primordial universe was inflating or contracting, and how fast it did so. Falsifiability should be a hallmark of any scientific theory. The attributes people have proposed so far to measure usually have trouble distinguishing between the different theories because they are not directly related to the evolution of the size of the primordial universe, he continued. I dont believe a word cosmologist say anymore. By Peter Reuell, Harvard-Smithsonian Center For Astrophysics By its very nature, inflation wipes our Universe clean of any information that came before it, imprinting only the signals from inflations final fractions-of-a-second onto our observable Universe today. The large, medium and small-scale fluctuations from the inflationary period of the early Universe [+] determine the hot and cold (underdense and overdense) spots in the Big Bang's leftover glow. Before we figure out what happened before the beginning, it is important to know how physicists think it will end. This is a BETA experience. Some size and time milestones are marked, as appropriate. Which once again begs the question, what existed before the firecracker and how can we wrap our minds around or explain the notion that at one time there was nothing that somehow became something.. Lets look to the Universe we see to find out. Picture Information. Before the Big Bang The Origin of the Universe and What Lies Beyond - Kindle edition by Mersini-Houghton, Laura . There was nothing material before the big bang. Then one day I thought, This is preposterous and with the internet available I searched for alternative ideas. And my post is blasphemous. Hover to zoom. No matter how tempting it may be to think that the Universe arose from a singular point of infinite temperature and density, and that all of space and time emerged from that starting point, we cannot responsibly make that extrapolation and still be consistent with the observations that weve made. Hello everyone..See the bitter fact is that Scientists are fooling us since the very start.. Before we figure out what happened before the beginning, it is important to know how physicists think it will end. However, there is a limit to that extrapolation, as going all the way back to a singularity creates puzzles we cannot answer. However, according to Professor Cox, there was a time before the Big Bang in which the universe actually existed.
