Black Hole

[Amorphic]

Thats true, I think it depends on if the black hole is approaching you or you just go into it. Maybe matter rips apart at a certain speed no matter what your velocity is towards the black hole. I just heard that if you were on Earth that gravity would lighten and everyone would be all "yay yay" hoping around having a good time untill you get particlized lol!

now that'd be a sight to see

now that'd be a sight to see

Is it safe to say that if Tom Cruise reads this forum that we will see on TV soon:

Matter Man

starring Tom Cruise

[Amorphic]

if it was tom cruise he would use his scientology to save us from the black hole

i've always thought that it's another dimension at the other end of a black hole think about it......it sucks matter in right? sucks it where? sucks it to another dimension that uses it? it could make sense....black holes could be a like a cosmic recycling system....transfering matter back and forth between the universes and/or dimensions on a regular basis

and with that i think i'm changing one of my majors to physics lol

And all of the theory's of it being like a funnel and just vaporizing everything is just that, a theory. Hahahha I would laugh at the tom cruise thing, and he would be the first douche to get particlized!

Well, some theorize that black holes either take information out of your universe into another or your univerise is on the receiving end of the information.

You ever hear of the theory that our universe is just one universe in a sea of universes floating around in some other type of huge space? And that some believe two universes collided to create our own universe?

JOHAN HELP!!!

[qualityclrk1]

black holes are just absolute gravity. if you get 'sucked' into one you are just obliterated (crushed) by the immense gravity

^ Yes..............and could you imagine if a star were to get pulled into this?...BOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOM

[samoth]

The simple answer is that you would become one with teh singularity.

All of the "answers" for these types of questions are basically pulled from the governing mathematics, so anyone truly interested in such should polish their basic math skills and pick up a non-popular book or two.

yes i've heard of this....we do need johan though.....he actually gets to study all this cool shit i just do boring regular engineering physics

the math used to "prove" this stuff is by no means at all simple lol.....it's highly theoretical in nature in and of itself and very very hard to follow even if you have a mind for it......aka why only people like stephen hawking can work such complex problems out.

I pray to god its not sound garden singing black hole sun! That is one of my least favorite songs ever.

or maybe Radiohead singing BlackStar - one of my favorite songs

Yeah man, this field is way off of my major. I will say this though, since this past year and watching some stuff/reading things on black holes, worm holes, astroids/comets/meteors, etc...my interest in this stuff has peaked. Obviously you have to know some high levels of math but this is interesting to me. I know most of these guys are genius' and such but still fascinating none the less.

I just read about this...they said there is a debate on whether you would become part of the singularity or would you actually be in another place.

You have any good books to recommend Samoth?

Much of the math is accessable with a working knowledge in mathmatical physics or a pure maths background through real and complex analysis, which is rather simple compared to, say, Penrose's twistor theory. Relativity's got nothing on quantum gravity theories WRT mathematical formalism, lol.

You would be in another place, or an entrapped photon or massless particle would be in another place? (Huge difference, lol. "Place" takes on another meaning here in the latter case.)

There are many, many books out there from popular to theoretical-technical. Recommendations would depend wholly upon your math background. A basic knowledge of mathematics (where "basic" is defined in science as up to and through multivariable calculus, basic differential equations and linear algebra) is pretty universal to seperate Nova specials of pure analogies (often misleading or blatently false) from something of substantive relevance, like the basic working of the Friedmann equations modeling the universe.

However, for anyone with more than a passing interest, I would highly recommend Roger Penrose's latest masterpiece "The Road to Reality", which is about 1200+ pages or so, and covers many of the mathematics rather informally, giving the layperson a conceptual access to anything from lie groups and tensor analysis to diagrammatics and spinor algebra. Not light reading, but I would still classify it as a popular book.

I've been in a black hole and back.....oh wait, nevermind

[Z-Ro]

^^^ wanted to see Johan's take on this : )

[Kärnfysikern]

Id say that the best answer and perhaps the most boring answer to what would happen is that nobody knows for sure The best gravitational theory we have(Einsteins general relativity) isnt valid anymore under those circumstances. I doubt such a thing as a singularity even exists in reality, its just a sign that general relativity isnt applicable and that we need quantum gravity to know what happens inside a black hole.

It would be quite amazing and exciting if wormholes and the like is possible solutions to any future working theory of quantum gravity, but the quantum gravity theories is way way over my head. Samoth knows this stuff way way better than me, I just briefly studied general relativity a bit but not enough to understand it.

yes i've heard of this....we do need johan though.....he actually gets to study all this cool shit i just do boring regular engineering physics

Well Im more or less doing engineering physics nowdays aswell I have changed my mind and going into reactor physics instead of theoretical physics. After taking a few highly theoretical classes I realised that I dont find it that fun anymore, I realy want to do more hands on stuff.

Funny how things turn out, I could not have imagined myself saying such a thing just one year ago! Cosmology, general relativity and quantum field theories is realy interesting, but the maths is ****ed up and the odds of landing a research position is slim to none.

black holes aren't even visible so you would never know if one was near our solar system... astrologists find black holes by plotting stars on a map, and they will observe the stars over and over. Once they find stars missing, they know a black hole sucked the star up and there is a black hole in that area. Astrologists also know when they found a black hole when they shine light into an area in outer space and the light beam just dissappears (this is the black hole sucking up the light rays)

[Kärnfysikern]

I hope you mean astronomers

A black hole acctualy consuming a star is a very rare process(except in galaxies where the supermassiv black hole in the center still has stars available to consume). But if we notice stars changing direction suddenly for no good reason or orbiting around a invisible object its a safe bet that the object is a black hole. Here is a nice clip of stars orbiting what is belived to be a black hole.

Its a bit of a missconception that black holes consume everything close, black holes realy behave much like any other celestial object. If for instance the sun was compressed into a black hole nothing would happen to the orbits of the planets in our solar system. If we compressed the earth to a black hole the moon would not be effected at all and would continue in its orbit as usual. Only a object heading straight into a black hole is consumed, otherwise it will just settle in a stable orbit.

astronomers yes haha.. that was a very interesting post karnfysikern, thanks for the excellent read

Until the trannies come out and tell you to bend over.

You really think that going through a black hole would take you to San Francisco?
