Black Holes are cool!
 

Who here thinks black holes are cool?

The idea of a rip in spacetime is odd but kinda cool. Well, I may just be a geek too, but thats besides the point. :D

Re: Black Holes are cool!
 

Yeah it is interesting, I like the idea of them connecting us to another universe or something, I wish I could watch one live.

Re: Black Holes are cool!
 

I think black holes are very interesting. Mainly because no one really knows what happens when you go through it.

It could be a rip in time, or perhaps you eventually pop out in another part of the universe, or an entirely different universe all together? Its one of the things that makes space so mysterious and interesting.

I think I read somewhere that most scientist think that when something enters a black whole (including light itself) it cannot escape. The gravitation pull of the hole is too strong to let anything out. They also think that when something enter's a black hole, it gets stretched out. It stretches in one direction, making any object that enters the whole turn into one giant stick of licorice. The black whole continues to stretch the object, but since matter cannot be destroyed nor created, the object never really ceases to exist, it just keeps getting stretched out longways. Also, when it's stretched, it isnt symmetrical, if you know what I mean. The end of the long "string" of matter that is closest to the black hole is narrower than the other end.

Although this is the most logical explanation, its not that interesting.

"Come on ma! We're goin to da black hole todayr!"

Re: Black Holes are cool!
 

black holes are really interesting ... i learned a bit about them in astronomy in high school

also, when i don't know where a friend has gone i use the expression "he/she fell in a black hole" or for select situations i say "he/she turned into a black hole"... i think they're fun

worm holes are cooler if you'd ask me :D

Re: Black Holes are cool!
 

ya, the fact that its theoritically possible to survive a wormhole makes it that much cooler than a blackhole. nonetheless i still think black holes are cool. the fact that the length of a blackhole the size of a caravan can stretch an entire galaxy is mindbogolling

Re: Black Holes are cool!
 

what happens if a black hole were to form near another black hole, would the older black hole win ? j/k.. It's still makes me wonder what would happen if a black hole were to form near another would it inturn suck the other in ?

Re: Black Holes are cool!
 

it all depends which ones got more gravitational pull i guess, although i think i can reasonably assume catastrophic results will occur in the surrounding area

Re: Black Holes are cool!
 

Ummm. I dont think that is possible. A black hole is formed when a star gets so large that its gravity is too much for its structure to support itself. The result is that the star collapses in on itself, and because of the extreme gravity, it continues to collapse upon itself. This repeated process of collapsing eventaully results in the gravitational powerhouse we know as a black hole. Also, black holes only have a certain "power radius." Its almost like an invisible line is drawn at a certain distance from the blackhole. Within that line, everything with mass is sucked in. Something could be just an inch on the other side of the line, and the hole would have no effect on it.

So, in order for two black holes to form within each others "power radius", you would basically have to have two stars right next to each other. I realize that this is possible in a binary star system, but in binary star systems, one star is usually larger (with more gravity) and eventually "wins" on the tug-o-war battle. In this case, it would be virtually impossible for two stars to be in a binary star system and BOTH of them be larger enough to form black holes.

Its not impossible, but its highly improbable. Evidence of its high improbability is shown through the fact that we have never seen a "binary holes".

But, the thought of twin holes being next to each other is a odd thing to consider....

Like, what if they got sucked into each other???? :eyes:

Traveling through wormholes would be awesome, but there are a few problems with traveling through wormholes that makes it pretty hard. Firstly, most people believe that wormholes would break up if you went through it because they are unstable devils. Also when light goes into a black hole, it's frequency is increased, or "blue-shifted" to such high frequencies that everything inside would be fried. And there is still all the incredible gravitational forces to deal with.

Some people think that when you enter a black hole, since time is all distorted and stuff that you see time pass by really fast, like going into the future.

Re: Black Holes are cool!
 

I still want to learn about the relativity theory of Einstein. :D

I saw 'Contact' yesterday, the travelling through the space part is awesome! :D

Re: Black Holes are cool!
 

sigh, i miss my astronomy class

i think the time shifts and space shifts that would occur when traveling through deep space are one of the most interesting parts of it all

Re: Black Holes are cool!
 

space in general interests me...it's just so.....cool! :p

Re: Black Holes are cool!
 

Someday humans will live aboard massive stations in space that cruise at super fast speeds allowing them to live much, much longer then they do on Earth.

Re: Black Holes are cool!
 

Well, only longer if you compare their lifespan to how much time passes on Earth. The people on the spaceship will feel the same timeframe, everyone else just ages more due to relativity.

I found out that you can't actually see something go into a black hole. No matter how long you wait and watch, you won't see anything ever actually go in (if you are watching on the outside) since the gravity of the hole makes it harder and harder for light to get away, so as something gets closer, the light it emits takes longer and longer to get to you.

Fascinating stuff. I have always loved space too.

Re: Black Holes are cool!
 

ya, i heard about that, as soon as the person crosses the event horizon, theoreticaly they will just seem to freeze on the spot.........they will have already gone in teh black hole, but the gravitational pull would be just enough to keep the photons from moving.....pretty crazy stuff

Re: Black Holes are cool!
 

Yes, but the interesting question is whether or not peoples perception of time changes. As you said, everything is relative. To us, it would seem that humans travelling at insane velocities were living a very long time. But would our brains compensate and would we view time the same way we view it now?

Eh? Eh? ANSWER ME DAMMIT!

Fungah...

Re: Black Holes are cool!
 

It's very hard to be sure. We can only speculate as to how humans will perceive it. However, experimenting with atomic clocks moving at high velocities compared to them being stationary shows that the speeding clock actually ticks slower. Who knows if time actually slows at high speeds.

Re: Black Holes are cool!
 

That's some crazy stuff. REALLY interesting. :D

Shows how puny we are.

Do you know the paradigm theory of Kuhn? It explains that people believe in a theory because it's 'popular'. It's the 'best' theory, but MOST likely not the truth. Everybody believes in it untill someone comes with a new and better theory.

Think atoms and stuff. People always thought that atoms are the smallest things, but now they've discovered that it actually consists of smaller 'things'... quartz or something. :unsure:

:D

Re: Black Holes are cool!
 

lol, that's "quarks" my dear boy.

Re: Black Holes are cool!
 

What are quartz again father?? :D

Re: Black Holes are cool!
 

It's QUARKS, dear boy, QUARKS. ;)

That makes a lot of sense because human beings always need a way to explain something, even if it is not correct. It just is a kind of satisfaction in thinking we know what's going on. Yet we keep on discovering new things and running into newer tougher questions that need bigger, badder theories to explain them.

Man, science is a neverending cycle.
