I have a rough idea of what a black hole is, but could somebody explain why there is a theory around that one could use it for time travel?

When matter travels into a black hole it just about dissapears. Where does it go? electrons, protons, light, everything! By the laws of nature it has to go somewhere. Most likely to a white hole at the other end of the worm hole created by the black hole. Of course this would be one-way...

looking back, as for time travel, i see how you could go forward in time because going through the worm hole doesnt nessicarily mean traveling fast. as for going back in time...its possibile that since the blackhole is basically a rip in universe you could end up elsewhere in time or in another universe...

I've heard about joining up the singularities of two black holes to form a wormhole...

...but this would be impractical for any living thing, not least due to the spaghettification effect, where the difference in the pull of gravity on your feet and head is so great you get all stretched and compressed and stuff

Blackholes have a hell of a lot of gravity (obviously) and i've heard gravity distorts time, i don't know much about it so i can't tell you much more than that.

Yes but my theory is that you would be "de-speghettified" as i call it on the other side and you would be fine...or you might not...

black hole is formed by star (sun)

basically the sun gathered to much mass that
it crushed on it's own gravity...
the hole is very dense, the gravity from it
can oppose the gravitional acceleration...
(e.g the gravitional acceleration of ur head
and legs is diffrent)

ur legs can fall faster, much faster than ur
head, and ur liver can fall much faster
than ur legs....
u will be ripped down to electrons, protons
and neutrons in a endless free fall....

e.g: G = gravitional acceleration

head's G = 1000m/s^2

body's G = 10m/s^2

liver's G = 2000m/s^2

in 1st second...
ur liver is ripped from ur stomach at 2000m/s
ur head is ripped from ur body at 100m/s
ur body fall at 10m/s....
(only electrons, protons and neutrons can stand that tear....)

gun nut stick to guns you don't know shit!! Why in the hell would your liver fall faster than anything else? That is just the first of all the glaring stupidness you just posted.

because your liver is closer to the black hole, in a few moments your head will be that close and traveling that speed. However your liver will still be exponentially faster/farther than your head.

get the special issue on scientific american TIME i think it was the september or october issue. they have a nice break down. so check it bicthes.

Is it possible that the matter is just getting compressed in the black hole and staying there? Isn't that what supposedly caused the big bang?

No. Why? because i suspect the matter is being transformed into photon x-rays, or just plain being destroyed. I know matter supposedly cant be destroyed, but maybe this is a condition where it can be.

im not trying to say that ur liver will fall
faster, im only trying to say that atoms in
your body fall at different speed....

which mean u get ripped apart.

I think that this "time travel" means that once you reach the event horizon of a black hole, you will basically stop in time, making everything around you go extremely fast

What exactly is your theory based on?

I could be wrong (its been a while), but time travel is theorhetically possible due to a real-time distortion in Space-time as matter accellerates towards the speed of light. According to Einstein, it is impossible to ever go faster than light, but as we gradually accellerate towards these speeds, our perspective as an object approaching light speed becomes distorted. They tested the theory using mach capable planes when they were invented with atomic clocks and did find slight distortions in objective time (the clock on the ground was different than the clock on the plane) after mach speed (speed of sound) was reached. In a black hole an implosion occures that sucks all matter (even light) in at such a velocity and strength that matter would accellerate towards the same speed as light changing the continuum.

I always regretted not taking physics, I hate not really knowing about this sort of thing.

Actually it is impossible to approach the speed of light from here because it would take an infinite amount of energy to go that fast. However things go faster than light all the time. *cough* TACHYONS *cough*

What? Thats news to me. What are Tachyons? Have they been proven to exist, or is it like a superstring thing? Are they part of Quantum Theory?

they are real, we dont have any use for them, however...

I may just be reading it wrong but iv never heard of that word and im to lazy to look it up online basicly what is it.

There is no direct evidence that Tachyons exist. There is very little indirect evidence either.

SpaceFalcon2001, go suck a nut. I happen to be an Andromeda fan. Most of what happens on the show is based on solid science, (with the exception of the gravity based technologys: artifical gravity, slipstream drive, and nova bombs). The black hole thing is accepted thory.

Ive not heard that, of course i just looked it up and the black hole thing is a stephen hawking theory. Actually i belive it, mainly based on my theory that black holes break more than space... ill get into that another time...or have i got into it already? nevermind...

I only skimmed most of the responses, so please forgive me if I repeat anything that was already said. I read a nice long article about the theory of time travel using black holes. The idea is that black holes are so dense that, under the right circumstances, two black holes could "bridge" and create a unstable link between space-time. this is called a worm hole. Now this bridge is very very tiny, not even big enough to get an atom throuh if I remember correctly. The next step would be to diolate this bridge so that a craft could pass through. Now the even trickery part. Next, you would need to 'lasso' one of the black holes and tote it around the universe faster then the speed of light. Then, if you were to enter the black hole that didn't get moved, you would come out on the other end before you went in. Thats the general theory anyways. Fun stuff
