Fuzzballs are theorized by some superstring theory scientists to be the true quantum description of black holes. The theory attempts to resolve two intractable problems that classic black holes pose for modern physics:
1.    The information paradox wherein the quantum information bound in in-falling matter and energy entirely disappears into a singularity; that is, the black hole would undergo zero physical change in its composition regardless of the nature of what fell into it.
2.    The singularity at the heart of the black hole, where conventional black hole theory says there is infinite spacetime curvature due to an infinitely intense gravitational field from a region of zero volume. Modern physics breaks down when such parameters are infinite and zero.
Fuzzball theory replaces the singularity at the heart of a black hole by positing that the entire region within the black hole's event horizon is actually a ball of strings, which are advanced as the ultimate building blocks of matter and energy. Strings are thought to be bundles of energy vibrating in complex ways in both the three physical dimensions of space as well as in compact directions—extra dimensions interwoven in the quantum foam (also known as spacetime foam).

this was an interesting one just seeing the sorta weirdness involved with string theory stuff when realized in larger scale ways. any version of a black hole is weird, of course. the conventional GR version of a black hole doesn't make me recoil quite as much as the fuzzball tho...just because the fuzzball is making a potentially huge hole in our universe, whereas the standard black hole is an infinitely small puncture. i watched this the day it came out, but i don't remember if they talked much about what would happen to fuzzballs colliding, maybe it was briefly mentioned iirc....but the point is i hope the string theorists out there keep trying to find some more large scale/testable (observable?) predictions for things like this so we can finally either move on from string theory (or of course if there's some truth in there then explore it further but that's not happening lol string theory is hot garbage).

It's good work because a major impact event is coming sooner or later, but wouldn't it be ironic if they accidentally sent the asteroid to hit Earth

space is the place!

according to michael bay- he already predicated all this would happen (so no worries about NASA making that ironic accident)

Connery would kick the shit out of it, then have a martini

"If you were a bumblebee at the distance of the Moon away from the telescope, we would be able to pick up the heat that you send out."

that's pretty fucking IDM

I'm glad this thing is finally about to be launched. I remember reading about it being developed so many years ago. Can't wait to see some far out images.

A short recap of the new telescope

also the chinese rover found a moon cube

James Webb telescope preparing for launch 

today the planet gets the best xmas gift

ngl, part of me wants the rocket to explode mid-air just to see the look on the nasa engineers' faces  

Looking good so far? I logged off after 15 mins or so. Was looking good until then. Hopefully first results in 6 months or so. 

Twitter embeds are currently still borked but all looks good! short shot of the JWST being sent off on its own!
