Ok I've been meaning to ask this in the Space community or the NoStupidQuestions community. I've seen this news circling around the past 2 weeks and have been watching videos of people talking about it.
Someone correct me if I'm wrong but I think the gist is that astronomers discovered with the JWST that some galaxies at the end of the observable universe appear to be younger than they are supposed to be. So it kinda blows a hole in the big bang expansion where objects farther away should be older. And that somehow ties in with the theory that our universe is inside a blackhole.
It's fascinating but I don't know what to do with that information other than just be fascinated. I think it was Neil deGrasse Tyson who said "what does it matter to us? nothing", because us being in a blackhole doesn't change anything in the scale of our universe.
I've always liked this theory, imagining the cosmos is just a series/web/tree of black holes draining into the next. Everything gets recycled eventually.
It doesn't answer where it all came from. Whatever theory or religion you choose, there's no answer to this question apart from it suddenly appeared which implies something can be created out of nothing and that creates a whole lot of new questions and possibilities.
It's also just whitehole theory which is possible but we've never seen one and we likely should have by now.
It meshes well with my occasional feeling that reality is just circling the drain.
Clockwise or counterclockwise?
I gave it some thought and got vertigo. I'm going with counterclockwise.
I think it depends if you're in Australia.
We also have to remember that we can only see a bounded sphere of the universe from our frame of reference.
If we were to move our observation points to elsewhere in the universe, we'll be able to see more of the universe and challenge our current theories.
The JSWT sees only what it can, and our theories about the universe can only extend as far as that evidence. Those galaxies might appear to be younger, but the science is never finished!
Probably goes without saying
Another big part of it is that if the big bang happened evenly then galaxies and other objects should be spinning in random directions. So far that's not what's been observed. There seems to be a preferred direction everything spins in.
The direction the black hole "toilet" flushes as it sucks stuff in and smashes it against each other?
Maybe there's a parallel universe called Astraliastra where the black hole flushes the other direction!
It's amazing to me that an episode of the Simpsons like 30 years ago created such a widely believed completely made up fact.
That fact wasn't as cromulent as they made it out to be.
ETA: also, the myth about birds exploding by eating rice. An entire generation used bubbles at their weddings instead, in part because Lisa didn't fact-check a myth. (Not complaining about the result though: bubbles are lovely floating orbs of happiness, whereas thrown rice is a messy waste of food.)
The bird myth predates the Simpsons though. I did hear it was greatly spread by all the churches\wedding venues because they all didn't want to keep cleaning up all the rice.
For sure, Lisa doesn't tend to make up such ideas whole-cloth. It was just the first place I heard the myth and I remember kids at school spreading it after that episode. So it definitely spread the idea.
Maybe the far away galaxies are just the close galaxies seen from the other side?
I was joking. Unless it was genius of course.
I seem to remember that the science isn't totally settled on the distance to stars in our own galaxy so I am quite chill about cosmology.
