"also someone tell me where proxima centauri's oort cloud is on that graph"
Proxima Centauri is a red dwarf star with a mass about 12.5% of the Sun's mass
I'd guess not very far at all, but also simultaneously much further than you'd expect!

i looked this up. apparently we have never observed an oort cloud around another star system, but based on what we know about how the one around the sun formed we would expect many/most stars to have one. given ours gets half way to proxima centauri it's not out of the question they overlap if PC does have one.

Technicians at the government's Los Alamos National Laboratory settled on what seemed like a surefire way to win praise from their bosses in August 2011: In a hi-tech testing and manufacturing building pivotal to sustaining America's nuclear arsenal, they gathered eight rods painstakingly crafted out of plutonium, and positioned them side-by-side on a table to photograph how nice they looked.

terrifying story, astonishing that intelliegent and qualified people can get so lax around that stuff. not all bad news though, "undermining the nation's ability to fabricate the cores of new nuclear weapons" oh no.

there is an AMSR quality to listening to true believer physicists talking bout string theory. You know u don't need to engage with the science because u know it's ludicrous nonsense, so it does have a relaxing quality for me during bouts of insomnia!

perhaps not a very scientifically nuanced take - but it sure does feel like they were just making this shit up as they went along!

wasn't it something like the existence of 26 dimensions they theorised? lol is that enough for you!

I'd have theorised about 36 dimensions because it's a beautiful number

the right idea on >= 4 dimensions

the observable physical universe, or at least the current understanding of it, just isn't overawing and huge enough for some people - they want more!

Here is a thing that I have read and that I am not sure I believe: If you accept that more than one universe exists, you are almost inexorably drawn to the conclusion that an infinite number of them exist. With all the extant possibilities.
The reasoning goes that there is no logical boundary short of infinity. Like, if the total number is 52, one might ask, "why not 51 or 53?" Arbitraryness creeps in.
Hence, the suspicion that the number is either one, or infinite.
Personally I see no reason why the answer can't be 3 or 47 or 576.
The universe has no obligation to make sense to us.
