So scientists say that the Big Bang caused the universe but what caused the Big Bang?

Serious question btw please explain I am open minded to anything.

Most don't.
The Big Bang is a description of the early expansion of the universe, not a causal account of its existence.

In string theory it could be branes bumping into each other in higher dimensions. Also yeah I know string theory = crackpot theory = untestable = not even wrong.

The theory is that our 3d space (or 4d space-time) is like a surface that exists in a universe with more dimensions. This is like how paper exists in our 3d but is itself 2d. In string theory these branes can hit each other and when this happens that energy is dissipated into the brane itself (like if you hit a metal sheet and it starts to ring, the kenetic energy has dissipated into vibrational energy in the sheet. One of these collision events would cause a big-bang in our 3d sheet in larger dimensional space.

say the paper had cartoons drawn on it and they in their plane on the page attempted to understand an additional dimension that isn't flat on the page. It's a little difficult to comprehend additional dimensions when you cannot achieve a perspective from which they can be seen

In order for there to be cause and effect, there needs to be a before and after. We call this sequence of causality time.

Time only exists because entropy exists. That's literally the definition, look it up before you shitpost.

The big bang arose from a universe with 0 entropy.
Time didn't exist before the big bang.
Asking what came before is meaningless.

>>8330033
Oh, so you mean branes are higher dimensional planes or spaces that can contain universes, and each time two or more collide they /might/ create a new universe from the impact?

That makes more sense. The pic in >>8327649 confused me. I thought each brane contained its own 3 dimensional universe and that a new brane was created with each "big bang" collision.

So basically if this hypothesis is true, a finite number of branes could create an unlimited number of universes just by vibrating together over time?

the double pendulum isn't the foundation for an entire field of study.

heat transfer is based entirely on that same taylor expansion ass pull that navier stokes is based on, and any physicist will tell you we are still a long way from completely understanding fluid behavior.

but somehow thermal phenomena are totally understood yeah?

That's avoiding the question entirely. The existence of analytic solution is just a nice thing to have, nothing fundamental, there is no guarantee that they even exist.

which means our models are still approximations and that we lack understanding.

here's some pure philosophy food for thought:
we know space-time is a thing in some shape or form. we know it contorts, we know time runs at different "speeds" depending on the contortion. so, we know space-time is not an unmovable, unchangeable presence. with that being said, it's implications are obvious. "cause and effect" at extreme energies and tiny spaces simply doesn't happen like we are accustomed to in our everyday interactions. so maybe there was no "before" if space-time didn't exist in the form we are currently familiar with. if time didn't exist yet, there would be no before.

like i said, philosophy food for thought. better than stank memes. or maybe not

and the 3rd dimension is "inside" the 4th dimension. Just because there's no example of a truly 2 dimensional thing existing in our 3 dimensional space doesn't mean they don't exist. We just have to define our 2d "object" very precisely.
