How close to a black hole might one be able to relive the past?

Question

Here is a little theoretical conjecturing / sci-fi / flight of fancy / masturbation (take your pick) based on the remarkable time-symmetric properties of general relativity equations. Obviously if we start with the solution that describes black holes, but instead imagining the time to flow backwards, we’ll end up with a perfectly valid solution to the equations of general relativity known as a “white hole” (i.e. a time-reversal of a black hole) [and notwithstanding the highly improbable possibility of their actual existence in observable reality]. Furthermore, if we consider a rotating and/or an electrically charged black hole, it is conceivable to envision that one can fall into such a black hole and never actually hit the singularity.

It is further possible to imagine that the interior of a rotating or charged black hole can meet up with a corresponding white hole in such a way that one can fall into a black hole and pop out of the white hole - in other words, travel through a wormhole. Now given the convenient speculation that a white hole can be somewhere very far from the black hole, possibly even in a parallel Universe, one can travel vast distances through a wormhole (potentially even to a different Universe). Finally, it is theoretically plausible to imagine that "the exit" to the wormhole could lie in the “past”, so that one could travel back in time by merely going through it.

Answer 1

You have to go into the wormhole which is just near the singularity.

Answer 2

I for one do not know where you got your information, but no researcher has ever stated for a fact that time travel is possible be it forward or backward. No machine has ever been close to a black hole, and no person is scheduled to do so now, or in the future. The speculation that time could be effected stems from the idea that matter upon nearing the event horizon begins to accelarate to near light speed, which Einstein believed would cause a time distortion. However this was not proven, and therefore still remains in the realm of speculation at best. There was an experiment once where two clocks were placed aboard two planes travelling in opposite directions one with the direction of earths rotation and the other againts the rotation, by the time the planes met each other on the opposite side of the earth the plane travelling againts the rotation of the earth had gained I think 10 minutes. so what! The idea of time travel still remains the brain child of a once great man.

Answer 3

Never. Everything gets trapped in a black hole. At one point, the event horizon, the pull of gravity is so great that even light can not escape and is pulled back, which is why it appears black, light can't get out. This does not change the passage of time. Time as we know it, only goes one way, forward. You might find a why to stop it, but reverse it? Very unlikely. However, below ais a quote from one of the most brilliant minds ever...

Answer 4

Not how it works.

The closer you get to a black hole, the slower your relative time goes. It doesn't ever kick over into reverse. You however don't experince the change of relative time. Time feels the same to you and your watch appears normal.. but when you look out, you see the entire life cycle of stars pass in a few hours. If you go past the event horison, time probably stops and you'll experince yourself as falling for eternity.. assuming, you know, you're able to experince once you're body's been ripped appart atom by atom and streched beyond comprehension because of the massive gravitational difference occouring at the front of your body in comparison to the back of it.

Answer 5

Please explain why you think reliving the past is involves proximity to a black hole. Unless you mean "life flashing before your eyes" as you're about to die by having all of your molecules ripped apart by extreme gravitational shear.
I'm not going to asume you've misunderstood the concept, but why don't you elaborate on what you mean?

Actually, it might be possible to enter the event horrizon of super-massive black holes, because the shear near the event horrizon might not be sever enough to cause a fatality. However, you would never be able to escape back out, and you would probably be vaporized by huge amounts of energy that might be orbiting the singularity inside the event horrizon.

Answer 6

I'm afraid you've misunderstood the effects that speeds near that of light have on time. What most people overlook is the word 'relative.' If you're moving near the speed of light, your time moves along at exactly the same rate as always, but to someone who's stationary relative to you your time appears to be moving much slower than their time. On the other hand, their time appears to be moving much faster than yours.

So, as you plummet towards a black hole and start nearing the speed of light *your* time doesn't change at all.

Answer 7

if you get close to a black hole you won't relive the past. instead you'
ll be put on a one way trip to the future. as you get closer to the vent horizon time will seem to speed up (for you) you will see stars dying and new ones being born, evnetually you even might see all of the stars burn out and leave nothing but a black void. you cannot get to the past this way. interesting way to see the future though.

Answer 8

It's like a problem out of Stargate SG1...

Answer 9

You will be spaghettified before any changes to your relative time rate will change because of increased velocity.

Answer 10

Do you mind if I live close to my rabbiT hole to live the future? lol
