> 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.

Might as well believe in God if you’re going to believe in spontaneous accidental creation…

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 that guarantees that science is capable of answering all questions.

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.

In this version we're still inside the black hole.

I guess that's a joke, but it's actually kind of serious that causality, personhood, identity, free will, etc. are all social constructs. They are useful to us, but every now and then it's helpful and humbling to remember it's a fiction we assign, rather than fundamental. Criminal justice or the concept of culpability is one of these areas. I know I've seen material by Robert Sapolsky, a neuroscientist who does not b…

That doesn’t affect time in the sense discussed here, though, which is a fundamental dimension in our physical theories.

It's been several years and I'm not fresh enough to summarize it, but some time ago I read Carlo Rovelli's "The Order of Time" which is a pop science book on why that isn't true. Ymmv. I'm sure many reading this know more than I do about the topic.

There is no proof of "nothing " existing. Every observation we take, we see "something".

Than why do we need a beginning if there was always something.

Strictly speaking, modern cosmology does not treat the Big Bang as the beginning of all of existence, it's what happens when you take observations about large scale cosmology and run them backwards in time.

Based on the information we have available about our universe, we can't make predictions or formally model anything prior to a certain point in time, consequently it's convenient to treat this moment as the earliest point in time in which physics as we know it makes any sense. So while there may have been some kind of existence prior to the Big Bang, we have no way to make sense of it even at a conceptual level. Given that, we may as well treat this special point in time as the beginning of the universe as we understand it and can explain it using physics, as opposed to some absolute beginning of all of existence.

You're missing the part where the robot was created by us.

Wow, that makes it even dumber. That idea was literally also in Genesis as the original sin of man: "You shall be as Gods." Edit, for posting too fast: I don't consider the response below to be in good faith, for if there is a God, nothing could be more offensive than to deliberately try to knock him down a few pegs to be "plausible"; while considering the Big Bang to be "plausible" because that doesn't count as "fan…

You're being downvoted for a bad read of the material. Any comparisons to God are intentional and deliberate - but mostly serve to knock God down a peg or two by grounding it in something plausible instead of the faith based miracles and straight up fantasy style magic from the Bible.

Futurama has a great episode where Bender meets God (who has merged with a computer) that tackles similar themes.

If you find this to be a harsh reaction, maybe consider how the wording of your initial comment is an effective provocation to anyone who doesn't share your belief system.

"beginning" is a misnomer, since time itself started with the Big Bang. There is no such thing as "before" the singularity, as time and space were curved together.

Time is a map of the states of consciousness, I believe consciousness/awareness of the universe has no beginning just infinite layers of abstraction.

How so? If you attribute it to an earlier universe, you are just pushing the problem further back. It doesn't seem to be a proof or even a mild indication.

I speculate that the big bang is/was fueled by all the black holes that existed and will exist, like a huge cycle where all the energy sucked into black holes converges at the same point in time causing the big bang.

Fractal Universe - I discussed the idea with Benoit Mandelbrot back in '84 over beers, interning for him, before he'd published "Beauty of Fractals."

> The black hole universe also offers a new perspective on our place in the cosmos. In this framework, our entire observable universe lies inside the interior of a black hole formed in some larger “parent” universe.

Does it also follow that black holes in our universe contain universes internally, beyond their event horizons?! Seems like it should. Mind-blowing.
