chatgpt sure is getting good
I was over at a woman's house who hangs her paint-by-numbers drawings on the wall
she had a dozen or so of them
am I crazy for feeling like that's a little....
impressive
she connected the dots all by herself

I'd be interested to see if this goes somewhere
fundementally physicists just slap dark as a prefix when we know fuck all about the thing, so Dark energy being an inaccurate description is not the craziest upheaval
Yeah
Dark matter/energy I'd argue is one of the pillars of currently not understood physics, so chipping away at it would be a big deal
holy grail is still reconciling quantum mechanics and relativity since both are needed but incompatible as they are now
In general, that is why we assumed dark energy (we have no idea what it is, hence why it is called dark) has to exist, because expansion seems to be accelerating and we need a way to explain that
similar to how dark matter is used to explain the universe structure we observe not making sense otherwise
this paper is basically saying that "Actually, the expansion is not as uniform as we thought" from what I glanced at it
I don't know if it neccesarily rules out the existence of something like dark energy, but it changes what we know about how the universe is expanding, meaning we need to figure out models for that
I didn't really read the full paper, maybe I will give it a look later if I can find it
That is not how black holes work!
effect of gravity falls of as an R^2 force law, so you would need black holes so massive that it would be really be possible to have them at the edge of the universe but still affecting the center
The reason gravity is dominant despite being an R^2 force law is the masses involved are just that massive that it dominates
and most planets are essentially electrically neutral, so the other R^2 law (electromagnetism) is not important
and then the other forces are way weaker
I think one of them is an R^5 law or something, so it really only matters between atoms and inside the nucleus

Merry Christmas y’all
Merry Christmas
It's also the first day of hanukkah tmr
No, though I honestly don't understand why it and Easter move around every year
Easter is related to the moon
Chanukah follows the sun for some reason
Oh, now I understand why it's called the bunny moon
