If the big bang was the beginning of space and time, what happened 5 seconds before the big bang?

Question

I refuse to believe that the big bang was the start of everything in the universe. That is absurd?

Answer 1

I just watched a show the other day that attempted to explain this.
The theory is that there are parallel or many universes. Just like there are many galaxies within a universe. These universes float around like bubbles. When two of these universes collide they produce a "big bang" and another universe can be created.
I think the show was on the Science Channel. I found it very interesting to think that there is many universes outside our universe. Seems the more we know.. the less we know.

Answer 2

Our current understanding of physics fails to answer your question. If we "run the movie backwards", modern physics allows us to understand the Big Bang back to a fraction of a second after time zero. Then it gets so hot, and so dense, that our physics fails us. This may not be a permanent situation---if we had a good unified field theory, uniting gravity and quantum mechanics, there might be a way past this barrier to our understanding.

One speculation is that a Big Bang is something that happens every once in a long, long, long while in a vacuum (with minimum-energy fields) that is undergoing inflation (like our Universe seems to be doing now). In that case, the Big Bang happens inside a pre-existing spacetime, perhaps not unlike our Universe. Once the "bang" goes off, however, it wouldn't be possible to get from the old space into the new space.

Answer 3

Very good question - but completely impossible to answer.

Before the big bang there was no time - so there was no 5 seconds before it.

As far as we know at the moment, the universe began with the big bang (although it's still only a theory) - but we have no clue whether it emerged from something else.

Answer 4

The phrase "5 seconds before" is meaningless ... because time itself did not exist before the Big Bang.

Look, one thing you learn with science is that "absurd" things often turn out to be true.

Everything in quantum theory or relativity was once thought to be absurd. Heck, even the idea that the earth orbits the sun was once thought to be "absurd" (just look in the sky ... it sure *looks* like it's the sun that's moving!).

Scientists learn to live with "absurdity" if that's what the *evidence* points to.

In other words, if your intuition contradicts the evidence, then a scientist rejects the intuition. You of course check and re-check the evidence ... but in the long run, if your intuition contradicts the evidence, then your intuition must be wrong.

That is often the difference between a scientist and a non-scientist.

Answer 5

You can refuse to believe in gravity too, but gravity wouldn't go away. The thinking is that the Big Bang was the start of everything, including time and space, so there was no "before."

Answer 6

in certainty that we don`t incredibly comprehend, it incredibly is seen to have been fairly warm and perhaps that became the catalyst to it, the massive bang concept has not been proved besides the shown fact that it is the main rational clarification and there are theories as to the way it occurred and this coupled with the certainty that the universe continues to be shifting faraway from it`s centre sort of proves that on the beginning factor each thing interior the universe became there and in case you commute backwards in time, it would take 13.7 billion years for all issues interior the universe to fulfill at that centre, hence it is going to have been an experience that created the initiating, there are all varieties of theories approximately dark power, remember and anti-remember for the approach to commence, it is so complicated and it takes fairly some information, Wikipedia supply an exceedingly good account of the recommendations available and that i've got given a link to it, finally, it is the Earth that became formed 4.5 billion years in the past.

Answer 7

Either there was a big crunch from the universe before contracting down to a single point or there was just a lot of energy with the potential to explode in to the universe. There was something there but what it was who knows, the laws of physics can't model that far back

Answer 8

Why not a trillionth of a second before the big bang.
Before time zero nothing but a finite potential existed.
What ever triggered this potential may forever be unknowable.

Answer 9

Plenty of absurd things in the universe. All we can say is that nothing of this universe existed, not even time and space. All of the evidence points to this event being the start of this universe.

Answer 10

It was a blackhole. A blackhole still connected to another universe. At the moment of seperation the big bang occured as there would be no gravity to contain it and all the energy that was previously held together by the intense gravity is released in one big bang... or expulsion, repulsion, expansion,ect.
