to answer the questions that were left unanswered. . Because the beginning of the universe . etc.. etc.. etc.. There was no matter before the Big Bang, and all that existed was space-time and an ocean of energy that was practically calm, but softly vibrating. So , according to Sir Stephen William Hawking , NOTHING existed before Big Bang , as many of you may have seen in the interview of Sir Stephen Hawking (if not I had put a link below , just check it) . When we take a race back into time, we realise that humans created religion (Does God exist?)
In physical cosmology, cosmic inflation, cosmological inflation, or just inflation, is a theory of exponential expansion of space in the early universe. Cosmologist Alexander Vilenkin has convincing evidence that we are surrounded by expanding, bubble-like universes. The universal origin story known as the Big Bang postulates that, 13.7 billion years ago, our universe emerged from a singularity a point of infinite density and gravity and that before . "Before the Big Bang" would be, by definition, outside of our universe. The Universe has not existed forever. One of them is the world renowned emeritus professor Stephen Hawking at Cambridge University who claims that the concept of time has no meaning before the beginning of the universe. However, cosmologists were baffled by how uniform the map was. He explained that Einstein's Theory of Relativity insists space and time form a continuum. The first long-lived matter particles of any kind were protons and neutrons, which together make up the atomic nucleus. Then, it all went bang, giving rise to the atoms, molecules, stars and galaxies we see today. Space was space; quite literally a void of nothingness. there may be no way to know, because inflation erases any hints of what came before. In fact, it might not have had a beginning at all. Einsteins theory of relativity tells us that space and time are not independent but very dependent on each other. In that case,. The big bang is a central thesis of cosmology. The Universe began not with a whimper, but with a bang! It is difficult enough to imagine a time, roughly 13.7 billion years ago, when the entire universe existed as a singularity. - Quora Answer (1 of 980): Question Want to know an amazing answer to this question? He states that to ask what existed before the Big Bang is like asking what is South of the South Pole and that the universe has created itself as a one-shot . 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. They might or might not be supported by evidence, but such reasons always exist. Here's why it had to be there. I think the question "what existed before the big bang?" is a definite concrete physics question that one can hope will be answered near-to-mid-term. What happened before the Big Bang? Space, time, and all the matter and energy within began from a singular point, and then . A little research has taught me that before the Big Bang, all the mass in the universe existed in a tiny singularity. The symmetries of string theory suggest that time did not have a beginning . Fourth-century theologian St. Augustine wrestled with question of what existed before God created the universe. on LinkedIn Let's face it: to think that the universe has a history that started with a kind of birthday some 13.8 billion years ago is weird. Before the Big Bang there was no space or time. It came into being 380,000 years after the Big Bang. It is possible to construct hypothetical universes that are logical and self-consistent, with no time at all, or with more than one time. Either time did not exist before the beginning; somehow time sprang into existence. Question "What was happening before the big bang?" This might be the situation at the centre of a black hole. Share What happened before the Big Bang?
The topic of this article has interested many thinkers. "Before the Big Bang" would be, by definition, outside of our universe. The key is a new concept of gravity, which explains how such a universe could exist without violating the laws of physics. The Universe began not with a whimper, but with a bang! The Big Bang is what created everything. Since time slows around large mass, and this had all the mass in the universe, time didn't exist before this. answer, a new crop of philosophers are trying to provide answers. Technically this means there is no "before" the Big Bang, but I was wondering if there are any theories as to how that . Bad news, Big Bang believers scientists may have discovered something that existed before our universe was born and want to change the name of that singularity from the violent Big Bang to the more playful yet controversial Big Bounce. Science definitely cannot help here, and most scientists agree t. This might seem like a bit of a cheat, but there are other good . The Big Bang theory describes how the universe expanded from an initial state of high density and temperature. All the 'solutions' to the problem of what happened before the big bang involve pre-existing universes or conditions, at least one of which is said to have existed for ever . There is a tangible air of excitement as we witness the birth of a new science called Quantum Cosmology. Hawking offered a simple and direct answer. Perhaps what was contracting was an earlier universe, for example. Now, some scientists say that the Big Bang was not the beginning, and that there was a universe before ours.
. These came into existence around one ten-thousandth of a second after the Big Bang. Before the Big Bang. - Second ThoughtModern science seems to agree that . Before the Big Bang.
This is similar to the infinite cosmos idea, except the Big Bang happened in the middle. My assigned topic was "What We Don't Know About the Beginning of the Universe," and I focused on the question of whether there could have been space and time even before the Big Bang. Make your own professional website at: http://squarespace.com/secondthoughtWhat Came Before the Big Bang? Before that, we can't . Prof Cox says we should "picture it as a near-still ocean of energy, filling the void". Scientists have a few theories.Learn more about this story at www.newsy.com/70096/Find more videos like this at www.newsy.comFollow Newsy on Facebook: www.fa. Instead, he says anything that existed before the beginning of the universe as we know it has no role at all to play in everything . At least, that's what you're commonly told: the Universe and everything in it came into existence at the moment of the Big Bang. Read Or Download Gallery of from big bounce to multiverse what existed before the big bang - Low Entropy | ppt entropy and the second law of thermodynamics powerpoint, entropy october 2016 browse articles, entropy free full text where was past low entropy, entropy october 2016 browse articles, Times quoted as "after the big bang" are . Like a mountain looming over a calm lake, it seems the universe may once have had a perfect mirror image. The fact that we're living in this vast universe and understanding our place in the cosmos is really what good science is all about, and it may not produce a . So, it is actually meaningless to ask what caused the Big Bang to happen - there was no Universe in which that cause could have existed. Additional resources In the beginning, there was an infinitely dense, tiny ball of matter. This universal explosion gave birth to the first elementary particles, which then formed stars and galaxies. The matter was so dense that it was extremely unstable, and so exploded outward turning matter into energy. It's perplexed people because the question is what-- people want to understand their origins.
Maybe before the Big Bang, the universe was a small, slowly evolving fixed space, as theorized by physicists like Kurt Hinterbichler, Austin Joyce and Justin Khoury and . Some point to possible 'scars' left by a previous universe's black holes on our cosmic microwave background. Time, in essence, is a non-spatial dimension dealing with the concept of . . Otherwise, everything happens in the same way as our universe was created before. 25.03.2022 According to the generally accepted Big Bang Theory, the Universe was formed from an infinitely dense, tiny ball of matter. On the big questions science cannot (yet?) The universe has existed, we think, since the Big Bang, about, say, 13.8 billion years. On. So outside of our universe, time has no meaning. According to TechTimes, Hawking says during the show that before the Big Bang, time was bent "It was always reaching closer to nothing but didn't become nothing," according to the article.. Once you think about that, an even more difficult question arises: What existed just before the big bang occurred? So there is no reason why an infinite number could not have existed in the singularity that was before the big bang. What is the nature of time? You might be interested in this. What We (Don't) Know About the Beginning of the Universe from Sean Carroll. The inflationary epoch lasted from 1036 seconds after the conjectured Big Bang singularity to some time between 1033 and 1032 seconds after the singularity. What was before the Big Bang? One can hope to have a model that is roughly similar to the present one that cosmologists use, but quantized, and which is testable in various ways by observations of some sort. As the universe continued to expand and cool, things began to happen more slowly. "Nothing was around before the Big, Big Bang," Hawking said. It was born. Some physicists believe our universe was created by colliding with another, but Kaku says it also may have sprung from nothing: a completely empty eleven dimensional universe with no spin, no charge and no energy. "We also say that space and time both started at the Big Bang and therefore there was nothing before it." The statement that space and time did not exist prior to the Big Bang appears to present a logical impossibility, at least with respect to time. Then, it all went bang, giving rise to the atoms, molecules, starsand. The first long-lived matter particles of any kind were protons and neutrons, which together make up the atomic nucleus. Jun 9, 2020.
The new theory proposes that another universe 'existed' in a different "cosmological phase.". Universe before the Big Bang has become one of the hottest areas of research. It is impossible to know what existed before the universe. Some theories suggest that, before the Big Bang, whatever existed was contracting, rather than expanding, as our universe is today. The idea of gravitational redshift crossed Einstein's mind years before General Relativity was complete. This idea, known as the Big Bounce, was first proposed in the 1960s by Princeton researchers Robert Dicke and James Peebles. In Hawking's view, before the Big Bang, there existed simply nothing. That's a notion we have no grasp of and which may be a logical contradiction. If this scenario really exists, "Big Bangs happen all the time," says Kaku. To our knowledge, literally nothing existed before the Big Bang. It was the residual heat, the first rays of light emanating from that explosion, whose wavelength was now stretched to microwaves. Many physicists regard the question as meaningless, saying that the Big Bang which created the universe was effectively the beginning of . Where did the material come from that created the Big Bang, and what happened in the first instance to Space, time, and all the matter and energy within began from a singular point, and then . But if we think deeply for a while, if our universe has started witha Singularity (Big Bang),according to Big Bang . I knew of that paper! Around 13.82 billion years ago, matter, energy, space - and time - erupted into being in a fireball called the Big Bang. Researchers from Penn . Modern science explains the origin of the universe with the Big Bang theory: Our world arose from the explosion of singularity . 1 Answer. Cosmologist Alexander Vilenkin believes the Big Bang wasn't a one-off event, but merely one of a series of big bangs creating an endless number of bubble universes. What existed before the Big Bang? Others predict we might find signs that the physics-breaking boundary we call the Big Bang never happened. What Existed Before the Big Bang. Explanation: The most common theory is that before the big bang there was a superdense sphere of matter. What existed before the big bang? The 50-minute video explains.
CDM (aka "big bang") cosmology starting at a cosmological time of some small fraction of a second, preceded by. A team of mathematicians has applied quantum mechanics to cosmology in order to come up with a . LAWRENCE KRAUSS: The question 'why is there something rather than nothing' has been around for as long as people have asked questions. Answer (1 of 15): The simple answer is that we do not know. In Big Bounce, the universe does not 'bang' but rather bounces - and thus has been forever in existence but is reset with each cycle (the opinions are out as to whether the reset produces an identical universe each time, or not). Scientist Hawking says there was nothing before the big bang, indicating a beginning and end to our universe. At least, that's what you're commonly told: the Universe and everything in it came into existence at the moment of the Big Bang. This is known as "the Big Bounce". A Universe Prior to the Big Bang Although for five decades, the Big Bang theory has been the best known and most accepted explanation for the beginning and evolution of the Universe, it is hardly . But we wanted to see if perhaps you heard Albert discussing this particular question at any time. It is the prevailing cosmological model explaining the evolution of the observable universe from the earliest known periods through its subsequent large-scale form. it is a strange offbeat paper because it USES the cushioning effect of LQG repulsive gravity (which I personally tend to think as having a good chance of being real) to cushion the collision of two imaginary objects (which I. The question itself predates modern cosmology by at least 1,600 years. Basically, this means that before the Big Bang there was another universe that existed, and a new one will emerge after ours eventually collapses. Was there anything before the Big Bang? Where there is no universe, no time, no causes or effects, not even sounds made by sheets of whipped cream five miles before. [2] The instant immediately following the initial singularity is part of the Planck epoch, the earliest period of time . These came into existence around one ten-thousandth of a second after the Big. If you believe in God like I do, there could be a religious explanation but currently we lack the scientific knowledge to actually be sure of what everything was back then. The Big Bang has long been taken to be our universe's beginning. Although there is no experimental proof as yet for it, the theory is so compelling and beautiful that it has become the center of intense research. Physicists have a pretty good idea of the structure of the universe just a couple of seconds after the Big Bang, moving forward to today. The Big Bang was the start of our universe, but there may have been one before it (Credits: Getty Images/iStockphoto) Sir Roger Penrose has claimed there was another universe that existed before . So it was not necessary for gravity to exist before the big bang. David Sloan, Postdoctoral Research Associate in Oxford's Department of Physics, discusses the thought . If you want to Save From Big Bounce To . . This is the Big Bang theory. The Big Bang describes how the Universe began as a single point 13.7 billion years ago, and has been expanding ever since, but it doesn't explain what happened before that. Simple. Modern science explains the origin of the universe with the Big Bang theory: Our world arose from the explosion of singularity . Did something exist before anything existed? Initial singularity. ME: OK, Bert, what about this whole Big Bang and what existed before the Big Bang. Other particles, (spin 1 particles like gluons) can exist in the same place and time. After the Big Bang, the Universe was . The topologically disordered spatial state must have already existed at the beginning of the Big Bang scenario.Because in the 4D plane is the whole set, otherwise any start would actually be a singular event. Before we can answer the part about the big bang, we must first delve into the potentially speculative nature of time. It took 380,000 years for electrons to be trapped in orbits around nuclei, forming the first atoms. And there, too, there was the constant changing cause . An earlier universe collapsed into the singularity that started our own. Allow me to explain. For something to exist, there must be material or a component available, and for them to be available, there must be something else available. Did something exist before anything existed? What Existed Before the Big Bang. Other cosmologists have also suggested searching for hints of our Universe's hidden past in the swirls of light and matter in the sky. According to the theory, a distorted mirror of our universe contracted until 14 billion years ago when it .
The Big Bang is the moment that space and time (or 'space-time') came into existence. These were mainly helium and hydrogen, which are still by far the most abundant elements in the universe.
