Current Events > Was there a beginning point to the Big Bang?

(+) Yeah! (+)

Like a place or sector of the universe where the Big bang originated? What would it look like today? Some kind of pre-mordial space-time hole?

Or did the Big Bang just start "everywhere" at once?

There was no universe before the big bang

I know that one of the hypothesis is that The Big Bang has happened multiple times. With the universe expanding and then collapsing and then banging again over and over.

Also...if it did happen all at once....what happened during the early universe? Everything must have been really close together. How come gravity did not just push all of matter together during the early universe to create some mega black hole or something?

We don't know. There's hypotheses but nothing conclusive. It could be cyclical. It could be that it emerged out of 'nothing'. It could be that there's a multiverse. It could be that it's the only time it's happened and ever will happen anywhere

I'd imagine the matter was too hot to form chemical bonds or some sciency sounding thing like that.

There most definitely was a focal point, and the universe has continued to expand out from that point ever since

One reason is that the formation of black holes is dependent on density variations. The universe at the moment of the big bang would have been uniformly dense

So all matter uniformly appeared in all places of the universe during the Big bang? I always thought there was a point that exploded and all of the universe appeared from that point.

The matter contained in the singularity was a uniform density and temperature, on our models

Just so people know, these are approximations. There's nothing certain about the origin of the universe other than that all matter seems to have emerged from the same position in space
