- not the one with Sheldon bumming Amy in blackface, but a stoner theory actually elevated to "real science" status.
The Big Bang may be a black hole inside another universe
We may be living in a daughter universe inside of black hole from a mother universe.

The whole origin-of-existence thingy is a chin-scratcher, that's for sure.

Really, this theory doesn't help us much. It just kicks the original can down the road. Where did the previous universe come from, eh?

similar to virtual particles. To start with, you just need a chance that something might appear. Eventually, something becomes a certainty. Then there is something instead of just the possibility of something. That is why when we examine the deepest levels of reality we find nothing more than probability.
Once there is something, that collects, makes black holes, and these become new universes.
These new universes have slightly different physics and some of these trend towards enabling more black holes. This also trends towards physics rules that support life.
We are probably many many universes deep compared to the prime universe. It is unlikely we will ever know what it was truly like.
Like a photocopy that has gone through the machine too many times, the original information is long gone.
Essentially, we are made from nothing more than the merest possibility that something might exist and a fuckload of something like time that made that possibility a certainty. Nothing is real and what there is, is falling towards a singularity that will destroy everything.
Have a nice day :)

Trouble is, "...you just need a chance that something might appear" is a big precondition to start with!
What was there before there was something, for the something to appear in?
It's hard to consider the origins of something so fundamental as space-time. Where was it? When was it?

Nothing, with a smattering of possibility of something.
Of course, this suggests that possibility itself is a fundamental part of reality separate from matter, space, or time.
Or at least it was in some other universe.
I find the concept of eternal inflation to be as likely, or possibly happening alongside.

If you have a spare hour to listen to people talking about it
There is another idea which I am not sure is being considered, which is that inflation is just how it looks inside a black hole.
The idea of being in a black hole inside a universe eternally inflating which in turn is inside another black hole etc etc etc is a real head asplode moment for me.
At that point, my brain says "Just give up and be a Buddhist"

Nothing or something has always been there for us to be here

if you let go of the concept that one thing has to happen after another and that time flows in a particular direction and has only a single dimension then it is possible that there is no 'before' or 'after', they are just an illusion caused by our motion through time and so as soon as a thing exists, it is possible for it to have always existed.

I think I am getting there in stopping my tummy from flipping the more I think about it. I guess we are just hard wired to time and a beginning/end as that's what we experience.

I'm afraid I didn't understand that. Could you stand on a mountaintop and explain it to a camera on a helicopter please?
( , Wed 5 Aug 2020, 16:43, Reply)

the helicopter flew me up there, my knees are not what they were.
But yeah, I'd love to go to exotic places and stand about looking real moody while a helicopter flew around. I could talk a load of bollocks about stuff while it happens if that is what is wanted.

It's only real science if it is experimentally observable. Unless you can provide a proper mathematical theory to describe it that is provable by experiment and observations then you might just as well say it's turtles all the way down.

Saying that the laws of physics break down at the singularity is trueish, but spaghettification and the weak and strong nuclear forces are well understood. 'You' are not getting anywhere near the singularity. Complete atoms are not getting anywhere near the fucker without being ripped apart.
Hawking revealed that black holes eventually evaporate 100% of their mass back into the universe that birthed them, therefore they don't send material or energy or information elsewhere, certainly not to another universe.
The properties of a black hole, 'white hole' and big bang singularity all share common and complimentary features. That does not prove a holographic universe, or a nested pocket universe, or a Boltzmann brain at the end of time simulating us in its imagination, or any shapeshifting reptile woowoo shit.

used as a thumbnail, get some wire wool and a 9V battery, a metal whisk on a chain and a camera on a tripod.
Put the wire wool into the whisk, touch the 9V battery to the wool and is starts glowing, spin it around your head and it burns and bits fly off.
Take a long exposure photo of that.
It's not a black hole.

a lighter works just fine. That's physics I guess.
