Time Travel using a Black Hole?

Question

Is it possible to travel to the past or future using a Black Hole, without the person and craft being hurt?

If so, any theorys on how this will happen?

Answer 1

A black hole is an object predicted by general relativity[1] with a gravitational field so strong that nothing can escape it — not even light.

A black hole is defined to be a region of space-time where escape to the outside universe is impossible. The boundary of this region is a surface called the event horizon. This surface is not a physically tangible one, but merely a figurative concept of an imaginary boundary. Nothing can move from inside the event horizon to the outside, even briefly.

The existence of black holes in the universe is well supported by astronomical observation, particularly from studying X-ray emission from X-ray binaries and active galactic nuclei. It has also been hypothesized that black holes radiate energy due to quantum mechanical effects known as Hawking radiation.

Answer 2

Black holes arent like that. If something enters a black hole, it would be compressed to a singularity and its matter would break down and mix with all the other matter within the black hole.

You should look into quantum theory if you want to know about possibilities of time travel. In quantum mechanics, nothing exsists until it i observed. Therefore, we, as conscious observers, are making it so that reality exsists. One cool thing, is that our brains actually can PROJECT BACK IN TIME! There was an experiment run where a finger was touched and it was recorded when the person felt it. They also stimulated the area of the brain directly to get that same feeling. They thought that There would be a delay when the finger was touched directly(because the signal had to travel throught the nervous system to the brain), and that the sensation would be felt immediately when the brain was stimulated. It was the opposite. The finger touch was felt immediately, thus the brain must have projected the sensation back in time in order to feel it immediately.

But in a black hole, time does not exist. In quantum mechanics, the laws of space and time do not apply.

No because in a black hole there is nothing, weird but there is no time, no gravity nothing and anything living would be crushed immediately into - nothing. No one knows where a black hole could lead to as obviously you can't get into one. Its worm holes that might lead to another time/dimension and these can be created (but no idea how) by punching a hole into space and making short cuts to different parts of the universe. But again its all theory I don't think we could live going through it. The only way to travel forwards in time(according to Einstein) is to travel faster then the speed of light then say you were in a space ship leaving the earth you would be able to look back and see yourself coming after you - bizarre I know!! Also the human body could not cope with travelling at lightspeed so it looks like we're stuck here then!!

Answer 4

yes in a way because when you enter a black hole time slows down to almost a stand still. One theory is that if you could enter a black hole and escape then you would have aged for example a few minutes and here on earth aproximately 1000 years would have gone by.
But that is if you could escape but the reality is that light can't even escape the gravitational pull of a black hole.

Answer 5

the black hole's gravity tends to infinite so it unlikely that a person or craft could travel to the past or future (if that is possible) like you say.It's like you are being pulled towards a single point smaller than one made with a pencil.Nothing can survive that - man or machine-

Answer 6

No, but I will be WAY, WAY, behind you in the queue for volunteers, given the known (or at least presumed) properties of a Black Hole... In fact, I will be so far behind you that, if quantum theory is correct , I will have to turn back to talk to you. Oh, and, hey, do you fancy dinner at Milliways?

Answer 7

There is no way of actually knowing anythigng about time travel.
And if you did manage to get to a black hole you would be bisected untill you were all atoms and then hurled into the vortex on the ride down to the heart of the quantum singularity.

Answer 8

Time travel is possible using the human mind , enabling you to access any point in space and time.If you were going to use a black hole I suppose you could approach the black hole at less than the speed of light ,then use the forces of the black hole to catapult you away at greater than the speed of light.

Answer 9

There's a very simple question that will help understand the possibility of time-travel, and it's this; Where are the visitors from the future ? If it were possible, we would be overwhelmed by people saying; ''Hi, I'm from 2106, would you tell me a little about your life please''.

Answer 10

"When you stand close to the pyramid of giza, it is known that things that are not near the pyramid move fast because of the great mass." - That's complete nonsense, sorry. Being near a black hole, you will experience considerable time dilation. The world outside will be blueshifted and sped-up in time.
