Can you cite your sources please?
Most jobs are really not important either, they just keep people busy. Do you need sources for this claim, too?
There are countless versions of this theory out there. Basically, a universe existed, then collapsed down to a single point, and then expanded again (the big bang). Rinse and repeat.
Is it the same universal every time? If so, see you later alligator.
If the Big Bang was just a moment in someone else’s universe, then maybe everything we know is just one chapter in a book far larger than we can imagine.
Suggested hard sci-fi light reading: "Cosm" by Gregory Benford, 1999. A universe the size of a bowling ball created in a laboratory. The scientist responsible for it, keeping it safe and on the run from gvt spooks. They want to protect it for as long as it lasts, and since its time is as relative as its size, they won't have long to wait.
Added. Opinions: A) I love all the scifi book recommendations that cone up on HN B) i wish you’d all stop recommending great and amazing books. My queue is so backlogged and jammed I'm never going to catch up.
The big bang sounds like how a computer would interpret being turned on. Anyone else think this is what happened?
Computers refer to this as 'the Big Boot'.
Interesting read, but even if we assume the author is correct, and the cosmos formed as a black hole in a larger universe, the question remains, how did this larger universe formed, then? Might just be impossible to know.
Maybe the larger universe is identical to the contained universe, like a fractal. That would solve the question. ;)

But who would be as cruel to put us here without giving us those answers? Who? And where did that entity come from?
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…
> When you cross a black hole's event horizon, the radial coordinate becomes timelike, so you lose one degree of spatial freedom. The second half is incorrect. Since the time coordinate becomes spacelike in turn you'll still have 3 spatial degrees of freedom. Dimensions can't just vanish if you believe that spacetime is a 4D Lorentzian manifold (as physicists do). Moreover, the singularity is not a place you can poke…
Can we say that one of the spatial dimensions (the radial dimension) and the time dimension combine into a single dimension? After crossing the event horizon aren't they 1:1 correlated?

Why not? If you can't observe it, test it, and reproduce it, then it lies outside the realm of science and in the realm of belief. Until someone figures out a way to experimentally verify the big bang hypothesis (or any other explanation for the origin of the universe or what came "before"), it's entirely fair to attribute it to whatever you feel like, be it a god or anything else. There is no law of the universe tha…
Well, I think surely the entirely fair thing to do is to just admit we don't know rather than make any attribution or imply any possession of an answer to those questions?
While we don't "know" how gravity works we can explain it and model it much more accurately now than when logos was the explanation. Providing those details is far more useful than a simple "we don't know."
