How big was the Universe prior to the Big Bang or was it simply a singularity?

Question

I am an attorney at law, this not a homework assignment, it is more of a hobby. I heard/read some time ago that the universe was 40 light years across before the BB, but now I note that is more likely just really well compressed singularity. What is the current collective theory?

I am just interested.

Answer 1

the theory now is that there really was no universe before the big bang, and there really was no before the big bang either.

the thought is that the big bang created space and time not only just matter and energy.

so there was no before the big bang because there was no time, and there was no space.

Answer 2

The real answer is, nobody knows.

Most people blithely say, "The universe began as a singularity," without realizing that 'singularity' is a point on a graph were a curve is undefined. It's a mathematical term used to describe a condition were the numbers breakdown and stop making sense; like what happens when you try to divide by zero.

Cosmologists can calculate with some confidence what the universe looked like up to about 300,000 years after the event we call the Big Bang . But anything before that is mere speculation until someone discovers new evidence or invents better mathematics.

Answer 3

The such a lot average and largely believed misconceptions approximately the Big Bang are that there needed to be anything "earlier than" it and that anything can't come from not anything. Since time and area are in detail hooked up (see Einstein ca. 1905), it's fair to anticipate that they each began on the equal occasion. Assuming that the occasion in query used to be the Big Bang, because of this time as we are aware of it began with the Big Bang. This means that any dialogue of what could have happened "earlier than" the Big Bang is kind of meaningless, considering the fact that time didn't exist then in any respect. There is also no such factor as "earlier than" the Big Bang. In reality, the idea does no longer deal with that obstacle in any respect. It best offers with parties that experience happened considering the fact that the Big Bang - for this very rationale. Therefore, this isn't a legitimate feedback of the idea - considering the fact that the idea does no longer even contact on it. At the quantum stage of truth, topic pops out and in of life regularly. You don't discover it when you consider that in our macro international, it's all smeared out into an typical that obeys the legislation of conservation of mass, vigour, momentum, and so on as tempered via the consequences of relativity. In reality, the operation of your laptop is determined by this quantum weirdness and could no longer role with out it. So the actual fact that you're studying those phrases is proof that anything is being produced out of not anything inside your laptop. This isn't extraordinarily intuitive fabric, and I can appreciate it if you may also disagree. But earlier than you disagree too strongly, please make an effort to learn up on a few brand new physics.

Answer 4

The theory most widely accepted today is the - singularity theory.

Indeed, current astronomy books say that the mass of the universe was contained in a single point.

Answer 5

It had to have been a singularity but blackholes do not give off explosions. There has to be a theory for what happens when a blackhole gets overloaded and explodes. perhaps our big bang was the death of a universe and in its death, ours was created?

Answer 6

A singularity.

Answer 7

the big bang "in theory" created the universe...before the big bang there was absolutely nothing, not even space itself. The big bang created space, matter, etc.
