how was Spacetime formed?

Question

Is there any theories or Hypotheses?

Answer 1

YES.

First all of time was formed into a massive long strip that went from the center of everything around and around until it came to the very edge of this massive thing we call the Universe. Then it was wound up into a very big ball and compressed with the power of unitrismal velocity until it became a fairly small ball. Then it was hurled out into the nothingness we call space. Enroute through the vast nothingness it began to unravel a little bit at a time. It is still unraveling as we speak today, a little bit at a time. And that is how time began, or was formed.

Please pass the biscuits, Dear.

Answer 2

Any theories on the creation of spacetime cannot be proven, since no living thing existed at the time of the Big Bang. Everyone may have different theories, so here are the facts:

The Big Bang was said to be caused by a tiny spec of energy that expanded to create the entire universe, but for that to be possible, there would have to be four dimensions--the first three to form the space for the matter to expand, and the fourth would be time, which would allow the matter to move outwards.

So in theory, this means that spacetime and matter were created at the same instant.

Answer 3

I can tell you that on the sub atomic level, the direction
or vector of time becomes ambiguous. And the smaller you go the harder it becomes to distinguish, right down the the theoretical limits on the order of 10 to the -43rd or so power.

Perhaps only after the very early universe had expanded beyond the current perception of the sub atomic realm
did time and space become distinguishable as separately
perceivable components of the same thing. Along similar lines to when the strong and weak nuclear forces became distinguishable. That only happened after the universe expanded and cooled to a certain point.

Only beyond that scale does time as we know it, become
distinguishable from space itself.

So to sum it up, space and time became separately meaning-full properties, only after the very early universe had all ready expanded beyond the smallest imaginable size, and the shortest theoretical division or particle of elapsed time.

Relatively tells us that time & space, matter and energy are
simply different attributes of the same thing.

Answer 4

the big bang theory is one explaination for the origin of space and time. but it wasnt like Eternacht said, the big bang theoretically created space and time. before the big bang there was nothing, partly because there was no before the big bang. its an impossible concept for human brains to grasp at this point.

maybe once our brains evolve again (since there hasnt been a major brain evolution in hundreds of thousands of years) we will be able to grasp the idea of not just having no matter but not even having the space to fit the lack of matter.

Answer 5

our laws of physics break down at that point. The 4 fundamental forces appear to have been comined into one in a way that we do not understand.

There are some far out ideas about branes colliding (superstrings) or such, but they are highly highly speculative.
