Maybe they aren't, but something about it makes sense, can I don't really know why.

I just had a dream that our universe was 1 of uncountable amounts of other big bangs, and after a certain amount of time (billions of years) big bangs occur within space created a previous big bang.

I wish I could animate this to describe exactly how it would happen.

For an example we would not witness this happen, because by the time a black hole ages to the point of a big bang, it has already consumed thousands or millions of galaxies, similar to how when our sun expands, we will die billions of years before it actually consumes the earth, in the same way that any living creatures in the distance of a big-bangs destructive force will be dead before it reaches that point.

So basically there are an inconceivable amount of big bangs that have taken place over potentially trillions of years, and that our universe was generated by a single chad blackhole that consumed enough material that eventually build upto a big-bang, which then exploded and expelled all its contents consumed from previous galaxies which then reformed into stars and planets again.

Even this is unironically 100% correct, it still doesn't explain why or how this occurs, and where it is occurring, and where does where its occurring, come from, and where does where its occurring come from, occurring, occur from?
