/sci/ - Black Holes

Name: Anonymous 2007-11-04 4:39

have black holes actually been proven to exist? when i was a kid i was all into astronomy and recently i've been looking into it again, and after reading several articles on the subject im still kinda in the dark. if you say wiki black holes there's tons of inferential information about them existing but no references to actual known black holes. also I just read some random post on /b/ (lol, reliable information) saying "as science has proven a blackhole is impossible (NASA news 2006) " <- anyone know wtf article he's referring to.

so tl;dr, blackholes: definately out there or an interesting theory?

Samefag.

The fact that light can't escape from inside the event horizon doesn't mean a black hole can't be seen.
Matter falling into it releases massive amounts of electromagnetic radiation. Even if there's no matter falling into it (or not enough to pick it up), there's still the Hawking radiation. Even if Hawking radiation didn't exist, you'd still be able to detect black holes through things like gravitational lensing and just due to the fact that they hide objects behind them.

Now go back to Gaia and stay there.

Not necessarily. Black holes can be formed by other processes as well.

let me explain this
black holes means they are black>means you cant see them
we can see the effect of them on the surounding space so we know theyre there
but unless your gona let me throw you into the core of the black hole and you can take a picture of it(not likley) we cant definetly prove they exist
option 2 wait for a big enouth star to supernova and then wach the fireworks as it colapses into a black hole

Neither do you. All we have are your posts but no one's actually seen you.

No, it's because it lacks any sort of light leaving a sort empty black space.

so like, what if you tie a rope around a guy, dip him into the hole, and then yank him out?

BLACK BODY RADIATION, NIGGER.

Can't yank, even if your rope would hold. Which it wouldn't.

What if it were a diamond space titanium alloy elven rope and you yanked at warp factor 5, captain?

When a black hole interacts with a supermassive giant star it's visible since it can't absorb all light. If they were never visiblem galaxies wouldn't be visible since they have a supermassive giant hole in the middle.

If like, I put a little black hole in my pants, could I poo into it?

Yes, and it would suck your ass after it, but it doesn't really matter does it?

Basically it's when a star's mass starts to bend light and we can see a star rotate around SOMETHING. We can't see it, but we see it circling something. Every galaxy is theorized to have a black hole as it's center of mass.

Look up Einstein's cross to refreshen the light-bending principle: http://en.wikipedia.org/wiki/Einstein%27s_Cross

It's one star, but since the light bends we can see it at different angles

Binary star systems are something you should research too =)

Probably the next thing the half-educated trolls will post is:

"Electrons! They're supposed to be smaller than light waves! If so, how do we know they exist -- we can't see them! Darrrr!"

Stupid fucking half-eds. BOTHER TO FINISH A COLLEGE COURSE INSTEAD OF FALLING INTO A MARIJUANA STUPOR HALFWAY THROUGH AS USUAL.

Black holes have been proven and there are plenty mapped. Stop yiffing and actually research you furfag

Oooo, so if I put my cock into a little black hole, it could suck me off?

correlating what you think a black hole would look like with a region of space does not a proof make!

not proven. welcome to faith, fag.
