Not many people these days like to hear this (I myself was one of them), but the answer to this is in Genesis. There's a reason some of the most famous mathematicians, scientists, engineers, and philosophers of all time believe(d) in God. The Hebrew name of God, YHWH, literally means "He Who Is." In other words, the Self-Existent One. The father and originator of all things that were, are, and will be, who exists out…

It would be a nice argument for deism - but to jump from that into anything more, seems way too extreme of a leap.

Why Christianity then, over Hinduism? Why any human religion at all?

I'm not a scientist or astrophysicist but i do believe in science, is it ok to believe that we as humans and all our scientific development still very very far from proving anything remotely close to how the universe got created? I feel this subject is for humanity in year 2600 to start discussing it. Scientist still can show their theories and search papers and i can't understand a shit but i don't believe in any th…

It's not about belief, it's about observing, collecting data & evidence, and proposing possible explanations. As new observations and evidence are found the possible explanations are refined. No one credible is claiming hard proof of anything at this point.

"In my room, redefinin' the meanin' of black holes" - Earl Sweatshirt

I went to school in a very bad neighborhood. Once I was sent to the office because my math teacher asked me what I was reading about that was soo much more interesting than our textbook. I happened to be reading "A Brief History of Time", so I answered "black holes."

At the time I couldn't understand why my dad laughed about that particular phone call from the principal.

Isn't time a human invention useful to model the nature? It's literally just a defined interaction as a reference, i.e. the sun rising up and going down which is the rotation of the earth. So IRL there's no time, there's no need to have a beginning or an end. Whatever happened when all the matter was close together isn't the beginning of anything, just a phase.

Not true. The arrow of entropy has a direction and it's the same as the arrow of time. There's not a good explanation for why though.

If time were running against the arrow of entropy, nobody could perceive or measure it, right? Remembering something is per se an increase in entropy, so the universe could run in negative time direction, but we would simply forget, what had happened.

That said, I personally think such thought experiments are futile and the nature of time has to be understood by its connection to causality and information.

> The Big Bang is often described as the explosive birth of the universe – a singular moment when space, time and matter sprang into existence. It is indeed "often described" in the media as such. However, that is _not_ the currently accepted theory. "What if there were no space and time before the Big Bang" is just Stephen Hawking's pet theory.

A more accurate summation would be that our theories do not permit us to go back beyond what appears to be the "Big Bang", and indeed, we can't quite get to it either, since the need for Quantum Gravity becomes too great as we get to what seems to be the "zero time". We have no principled, reasonable way to make any claims about what came before the point where our theories break down, and that includes the claim tha…

Interesting thing with this work is that it does create an observable, testable hypothesis: slightly positive curvature of the universe.

I've read somewhere an article which posited that our 3D universe might be inside a 4D black hole. When you cross a black hole's event horizon, the radial coordinate becomes timelike, so you lose one degree of spatial freedom. Movement is still possible in the tangential directions however, so what you get is basically an N-1 dimensional universe. So maybe our 3D universe is actually matter that fell into a 4D black…

Yes, and then there's the parlor game of guessing what familiar property of our known universe is actually a spaghetified fourth dimension. I guessed c once. It would be a constant. Maybe all the constants are spaghettified remains of a superior universe.

I thought that's what the high dimension counts of string theories were: taking constants and turning them into dimensions.

Or is that too simplified?

"Proving anything" is kind of fuzzy. We've got very solid evidence that some sort of big bang happened. We can see the galaxies flying away from a common point, and since we can count backwards, we can know roughly when they probably would've been in the same spot. The how and why, and the what happened before, those are very unknown, although we've got a surprising amount of knowledge of what the first few seconds were probably like.
