The Big Bang

[Llama]

Just a random thought.

Why is it sometimes argued that the big bang could not have happened by chance?

Surely chance is based simply on how likely something is to happen in a given time?

It is commonly accepted that space and time are both concepts created at the birth of the universe.

That would therefore mean that before the creation of the Universe there was no such thing as 'time' and so anything could have occured in this non-existance due to the lack of any measurable timeframe, thus making probability immaterial?

Please, no religious talk, just talk about whether or not i'm talking shit. :thumbs:

I'm sure there's a lot more to the formation of the big bang than 'chance'.

What with multi verse theory and what not.

 

[Llama]

True, I'm just talking about one specific argument however (Based on the idea this is the 'first' universe

 

[<RJMC>]

that because god farted and the rest is history

 

[The Monkey]

Nothing existed before Big Bang, no time, no space, no matter, no energy, no vacuum, so on what factors would that "chance" be based on?

 

[Llama]

Well that was what I was saying No factors for the chance, making it (at one point or another) totally possible for it to have happened randomly.

I just find it impossible to believe that there was ever nothing.

I think there was always something. The universe was always space, but not as we know it. After the big bang, space now has stuff in it. Things like light, particles, atoms, and matter.

It might make it confusing because the definition of space is an empty place, yet outer space is not empty.


Also, we will never know if there is an end to the universe or not. It is just too god damn big, no matter what technology we could ever come up with in a trillion years. So for all practical purposes, the universe is infinite.

If there is an end to the universe, then that means that there is something even bigger than the universe that our universe is inside of.

For example, the universe is a drop in an ocean that never ends.


There is no end to what is out there.

god did a big bang attack.

From wikipedia:

* models including the Hartle-Hawking no-boundary condition in which the whole of space-time is finite; the Big Bang does represent the limit of time, but without the need for a singularity.[52]

* brane cosmology models[53] in which inflation is due to the movement of branes in string theory; the pre-big bang model; the ekpyrotic model, in which the Big Bang is the result of a collision between branes; and the cyclic model, a variant of the ekpyrotic model in which collisions occur periodically.[54][55][56]

* chaotic inflation, in which inflation events start here and there in a random quantum-gravity foam, each leading to a bubble universe expanding from its own big bang.[57]

Proposals in the last two categories see the Big Bang as an event in a much larger and older universe, or multiverse, and not the literal beginning.

In other words, we just don't know. There is not enough data to determine what, if anything, came before the big bang, so theories on this topic are totally speculative, mathematical abstractions. Perhaps data from CERN will reveal new evidence which will support or undermine one of these theories, or perhaps generate a totally new one.
