It's impossible to know with our current understanding of physics

As questions go, that's a biggie for science.

Few theories are that:
>It just happened, then everything came from that.
>A previous Universe eventually collapsed in on itself called the big crunch.
>God.

You didn't have to start a whole thread about it.

Causality is a law of our universe, outside or before it, it doesn't necessarily need to apply, therefore the Big Bang didn't have to be 'caused' by anything an it's completely fine within our understanding of physics

So, this thread is full of nothing.

Inflation is what leads up to the Big Bang, it correctly predicts the spectra of light we see in the CMB (can't find the image which shows Inflation vs. other theories, it's in one of Guth's MITOCW lectures)

Part of Inflation is the fact that the rate of decay of inflation is slow than the expansion, which means there should always be parts of the universe which are inflating. This, combined with the idea that seperate areas can inflate at different times, leads to the idea of bubble universes.

Basically, what we observe as the big bang may have been one of many nucleations of space and time as we know it. Our universe may be part of some larger structure which may give rise to spaces like the one we occupy.

Im not sure I would refer to it as magic. Anything other than this seems to result in a infinite regress. Perhaps one day we will know what happened a t=0

All current observations indicate that the universe is expanding and that the expansion itself is accelerating. So a big crunch in the future seems unlikely and would require some mechanism that has yet to be found.

im reading a book atm about it, yet we dont know fk all about before big bang but this book is crazy as fk if u wanna get ur mind blown go get biocentrism pdf ull find it on google. It dosent explain what was before the big bang but it has some fucken mind blowing theories and stuff. Its said in the book we could be near of finding it, but in fact who fucken knows, i dont believe we near to find it as we are the universe observing the universe. Book is very interesting go read it!

actually the Quran just says steadily expanding, as in it is continuously expanding. i.e it didn't expand for a while, then stop, it kept on expanding.

Increasing steadily, is still steadily.

it isn't that ambiguous
I mean it isn't solid proof or anything, but it just makes one wonder why Muhammad, a sheperd in the desert, would say that the "heavens" were created by might, and that God is constantly expanding it

My theory on the quran is that it was just Muhammad reading the Bible and Torah once, and deciding to write his own version, but the above verse isn't mentioned in either of those books, not even something similar

OP. the universe is less than 44,000 years old. Allah and Jehovah were bored, all their people worshipped them unconditionally. They devised a scheme something like this:
1) Remove the obvious determinism in the human brain.
2) Seed the planet with (frankly ridiculous) evidence that te earth was REALLY old.. like argentinosaurous.. ffs lolled.
3) Skew the experiments.. the farther you look to find them, the more questions get opened up.. Its a theologically expanding labyrinth see?
4) Reflect all observations back on the observer who is questioning, to make him/her question more (red shift/dark matter etc)

All this.. just so YOU question your faith my son. Believe !

There was another universe. Universes might undergo periods of contraction and expansion. Right now we are in the expansion phase. Maybe someday the universe will contract instead.

Pick your favorite, no one knows. Our understanding of physics breaks down below the plank length so past that point goes more into the realm of philosophy until better explanations of the world around us are generated.

>> No.7207334

since you can speculate about it as u want, it could also be like booting a pc. maybe pressed play button on a futuristic quantum pc which started the big simulation

also universe can be seen as some kind of organism which reproduces (saw this on morgan freeman lol) and when a black hole manages to get enough mass to enter singularity, "on the other side" it triggers a big bang (maybe the energy has to go somewhere?)
also think this is connected to the white hole theory

If that is the rule for everything that exists in our universe then it is probably the rule for the universe itself. All life and existence is a cycle of constructing and deconstructing.
