What was there before the big bang?

Question

What exactly exploded
And how did it get there, or was there nothing there before it

If nothing was there, did nothing explode
and if nothing exploded why was there such a big bang

Answer 1

i guess atoms.or heat expands.

Answer 2

That's the big question, isn't it. Keep in mind the Big Bang is theory, nothing more than that. It's really just a conclusion based on the observation of the expansion of the univers. Scientists looked at the expanding universe, and assume if the clock was run backward all the matter would form together into a blob of matter. Then they needed a way to explain why the matter is now flying apart, thus the creation of the "Big Bang Theory"

Answer 3

Until recently no one could attend a lecture on astronomy and ask the modern version of Augustine's question - what happened before the Big Bang? - without receiving the same frustrating answer, courtesy of Albert Einstein's general theory of relativity, which describes how matter and energy bend space and time.

If we imagine the universe shrinking backward, like a film in reverse, the density of matter and energy rises toward infinity as we approach the moment of origin. Smoke pours from the computer, and space and time themselves dissolve into a quantum "foam." "Our rulers and our clocks break," explained Dr. Andrei Linde, a cosmologist at Stanford University. "To ask what is before this moment is a self-contradiction."

But lately, emboldened by progress in new theories that seek to unite Einstein's lordly realm with the unruly quantum rules that govern subatomic physics - so-called quantum gravity - Dr. Linde and his colleagues have begun to edge their speculations closer and closer to the ultimate moment and, in some cases, beyond it.

Some theorists suggest that the Big Bang was not so much a birth as a transition, a "quantum leap" from some formless era of imaginary time, or from nothing at all. Still others are exploring models in which cosmic history begins with a collision with a universe from another dimension.

its a weird worls i wish i knew lol hope this helped

Answer 4

Nobody knows the answer to this.

But there is a WAG proposed by string/M theorists like Dr. Brian Greene, Ed Witten, and others. [See source.]

Because string/M theory WAGs more spatial dimensions than our three, it allows for the possibility that other parallel, universes exist. Greene likens them to slices of bread in a meta universe loaf.

Well, according to the WAG, two of these parallel universes collide for one Plank time. And in doing that, their momenta are altered, which in turn releases the energy we know as the Big Bang. In other words, it was space itself that exploded.

In fact, for the first few seconds following the BB, our universe was filled only with energy...no matter. But as the universe cooled, again in the first few seconds, energy began to sort-of congeal into elementary matter...like quarks. And, to make a long story (15 billion years) short, matter has been congealing ever since as the universe continues to cool.

This is all feasible as we know E = mc^2 shows that matter (m) is just a form of energy (E). And physicists have in fact created matter and antimatter from energy in their labs.

Before you reject the idea that "nothing exploded," consider this. Space bends under extreme gravitational force, like from a super galaxy. This is not just a theory, warped space had been observed as gravitational lenses near super massive galaxies. So gravity is pulling on something, not nothing. There is something there to explode.

In fact, string/M theory posits that the fabric of the cosmos is really made of strings that exist in our 4D universe and higher dimensions. So some of those strings, like the ones that manifest in our universe as gravity, could coexist in multiple, parallel universes. This is one guesstimate (WAG) as to why gravity is much weaker than it should be based on theory. That is, some of gravity exists in other universes.

So, according to string/M theory, parallel universes existed before the BB. And it was two or more of these that collided to release the energy that eventually congealed into the remainiing energy and matter that makes up our universe. Finally, our universe and presumably the one that ran into it are made of something that gravity attracts. They are not nothing.

Answer 5

there may have been nothing or there could have been a universe or a infinitely small particle that exploded like a "maga" black hole, or the the big bang could have been a "maga" light hole that "poped" in and out of existents.

Answer 6

Nobody knows the answer to this. Cosmologists work on the problem, but they do not seem close to an answer yet.
