01.27.12 | fucking science, man |
FromDaHood
01.27.12 | Brian May has a doctorate in astrophysics. That shit blows my mind. |
Ignimbrite
01.27.12 | that is badass |
cb123
01.27.12 | astrophysics is quite interesting, wish i could have chosen to do my phd in that side of physics but wasnt really an option at the university i was at |
IAmHollywood
01.27.12 | you should have put BATS for 6

Ignimbrite
01.27.12 | i mean, i want to go into geophysics but still
what did you end up studying? |
wabbit
01.27.12 | so god made all this shit in one day but took and entire day making adam? And needed to take a rib from him to make Eve? |

01.27.12 | Event horizon and shit. |
IAmHollywood
01.27.12 | I salute you |

01.27.12 | fuck astrophysics, i'm moving to indiana

01.27.12 | Puke. |
IAmHollywood
01.27.12 | lol
but seriously this shit blows my mind to the next galaxy |
Yazz_Flute
01.27.12 | Humbling. |
cb123
01.27.12 | i went into optics but yeah astrophysics has some pretty insane stuff |
Ignimbrite
01.27.12 | "but seriously this shit blows my mind to the next galaxy"
that's pretty far away
but it blows MY mind to UDFj-39546284 |
Ignimbrite
01.27.12 | i win |
Acanthus
01.27.12 | Awesome list! |
robertsona
01.27.12 | im taking physics now and its sucking the life + desire to ever do science again out of me idk |
Ignimbrite
01.27.12 | i'm in advanced physics and astrophysics and both classes own hard
they're also insanely difficult (especially advanced) but whatever |
Satellite
01.27.12 | lol @ not being an english major
i don't need no motherfucking science |
cb123
01.27.12 | yeah i love the maths behind all the physics and ya can truly see how awesome that everything works the way it does and how seemingly unrelated fields share mathematical similarities. |
Ignimbrite
01.27.12 | i want to get a job someday so i'm not going for an english major |
IAmHollywood
01.27.12 | edge of the universe. beat that. |
Satellite
01.27.12 | hmm i hadn't considered that |
Sirob
01.27.12 | took astronomy last semester, some of the shit like this blew my fucking mind. |
Ignimbrite
01.27.12 | yeah things in the universe are hella big
it makes me feel depressingly insignificant |
IAmHollywood
01.27.12 | software engineering student here
lol English majors enjoy those essays |
feav233
01.27.12 | lol yea, astronomy is pretty cool |
Ignimbrite
01.27.12 | yea it is. science in general is pretty bomb though |
toxin.
01.27.12 | I'm pretty sure this is more astronomy than astrophysics.
Kind of want to be an astrophysicist but I'll probably end up being an engineer. eh |
Voivod
01.27.12 | 6 is so awesome. |
insomniac15
01.27.12 | the phases stars go through are just mindblowing, as well as everything about planets and black holes and dark matter and everything else. I wish I had been better at physics and math when I was in middle school, maybe I could've signed for the astronomy university |
wabbit
01.27.12 | I thought the current understand of the shape of the universe is that it doesn't have an edge but is expanding into itself. |
Hyperion1001
01.27.12 | well there are several models but i think the most widely discussed at the moment is that it is expanding back onto itself
there are some other really cool ideas floating around though |
wabbit
01.27.12 | are there any theories on where the singularity could have possibly come from? I know you have the big crush theory but that just delays the explanation. |
Ignimbrite
01.27.12 | my understanding of the expanding universe is that it's a three-dimensional universe expanding on a four-dimensional plane, like if you drew a bunch of points on a deflated balloon and blew it up (with the points representing galaxies, dark matter, etc). |
UnnamedOcean
01.27.12 | Astronomy is fucking cool. I really wish I could take more courses in it, but I don't have time for a year of physics and calculus. |
jefflebowski
01.27.12 | astrophysics rules |
Hyperion1001
01.27.12 | essentially what ive come to understand is that the universe is expanding from a singularity at a rate that is governed by the hubble constant. under this model, the universe isnt an infinite body, and has a critical density governed by the matter and placement throughout the universe. as the universe expands, eventually the density of the universe will exceed the critical density and the gravitational force will stop the universe from expanding and eventually reverse it, the big crush theory essentially
what is interesting though is that based on Einsteins equations and ideas about gravity, the force of gravity has the power to warp time. and what if all the matter in the universe were condensed down into one singularity? well, one theory is that time completely stops, or ceases to exist, until another expansion occurs. |
NWOAHM666
01.27.12 | Cool stuff here. I studied that in high school (I'm a technology student). |
jefflebowski
01.27.12 | My school textbooks from a few years ago all said that the the mass of the universe was less than the critical mass required for a big crunch, and it would just expand indefinitely.... |
Ignimbrite
01.27.12 | well, one of my textbooks says that stars cannot be over 150 solar masses so idk about them anymore |
jefflebowski
01.27.12 | yeah, a lot of astrophysics-based theories are pretty speculative anyway. not that that makes them any less awesome |
Nikkolae
01.27.12 | this list deserves a mastodon guitar solo. |
foxblood
01.27.12 | there's pretty much nothing more interesting than quantum mechanics and astrophysics. when i find someone that's into them i can get into a discussion for hours |
Ignimbrite
01.27.12 | yee, quantum physics is probably the most utterly confusing, fascinating, and mystifying thing mankind has ever attempted to explain
|
foxblood
01.27.12 | yeah seriously. watching documentaries and reading about it is just..ugh. i'm somewhat convinced it's a realm that the human mind will never have a capacity to even begin comprehending.
dude i talked with my old astronomy teacher about that hubble ultra deep field picture for like an hour once. probably the most impressive picture ever taken |
Hyperion1001
01.27.12 | yeah that picture is strange because the more you stare at the more you realize how absolutely positively completely insignificant you are |
foxblood
01.27.12 | yeah it's an inevitable conclusion hyper. the universe contains billions of galaxies, each containing hundreds of billions of stars, with TRILLIONS of planets in just the milky way. Billions of galaxies each containing trillions of planets. if you don't feel insignificant after that then you didn't think hard enough |
jefflebowski
01.27.12 | the HUDF image is just breathtaking |
jefflebowski
01.27.12 | I also find it awesome that the first 5/6 epochs of the universe occurred in less than a second |
wabbit
01.27.12 | ya pretty much everything happened in under a second. Like the laws of physics were created at that point. |
taylormemer
01.27.12 | Perhaps the most impressive model of the universe (still underway) is the Sloan Sky Survey. |
Ignimbrite
01.27.12 | I actually learned about that one today: pretty impressive stuff. |
jefflebowski
01.27.12 | http://en.wikipedia.org/wiki/False_vacuum
Vacuum Metastability Events are trve kvlt

Ignimbrite
01.27.12 | yeah you could name a bm album after that shit |
Ignimbrite
01.27.12 | or a djent album, but djent is way too gay for something that awesome |
jefflebowski
01.27.12 | heat death of the universe would be an awesome name for an album |
taylormemer
01.27.12 | Another one you guys should check out is 'quantum entanglement'. (that's actually certainly a good name for a djent album) |
jefflebowski
01.27.12 | i'ma definitely check that out once i've finished spending the next 2 hours on wikipedia reading about
black holes |
Ignimbrite
01.28.12 | i did that same thing last night except it was about hypergiants and how some of them are so big that they just blow into a bunch of heavy elements that get lost in the cosmic wind instead of forming a neutron star or a black hole
also i read about this theoretical object called a "quark star," where something i didn't quite catch happens to an overdense (a neutron star of "normal" density will weigh a billion tonnes for a single thimble full) neutron star and it shifts into an even denser star made entirely of strange matter. apparently the transformation from neutron to quark star would be more energetic than a supernova
yeah, and i also read about black holes |
