Is a black hole a time machine?

Answer 1

From what I've heard and read about the black hole, I don't believe anyone can enter a black hole and live. From what I've read, it sounds like you would be compressed. It would be like being crushed slowly without being touched. I'm just wondering if we can travel underneath it. If so, then we would know for sure it leads to another galaxy. It would be proof that time and space can be "torn" to go somewhere else. (Aside: You are only compressed in the relativistic dimension of travel. As you approach the speed of light you get less thick to an outside observer. To you, the traveler, everything is just fine.)

Time doesn't really exist. It's merely a concept that exists because our lives eventually come to an end. Therefore we need to keep track of time. It is impossible to go back in time because time is only a mental concept. For time travel to be possible there would have to be an infinite number of realities all playing each moment simultaneously. Even so we would have no way of accessing these alternate realities. (Aside: Einstein says something about reality that is applicable to time as well. He stated "Reality is an illusion, albeit a persistent one. ...")

Time exists because without time, the six string theory comes crashing down to a halt if you look at it carefully. It is not just a mental concept because we die, it is as real as anything else, and just because some people can't look behind the wall doesn't make it any less real. If you could time travel, the most complicated way is to send everything in reverse. But, I would most likely use the void (using the theories of alternate realities, there must be a void. otherwise the similar energy would merge (the void is the space between universes of universal radiation, and like two magnets repelling each other, the void is made up of a repelling force), for it does not accommodate time in any sort; it just merely exists, and you could basically just go from one spot of the time-space in the universe to another.

But to answer the original question, no one can because you are just being crushed into a size which most people believe to be impossible to measure, so they call it infinitely small.

Research on all the Science Fiction standbys (time travel, teleportation, etc.) is regularly reported in "Nature" magazine, a stodgy, peer-reviewed, British science publication.

I have also found material prepared by Dr. Michio Kaku, co-founder of the string field theory who has written on the role of time travel in modern physics. In one of his discussions he states:

"However, before Einstein died, he was faced with an embarrassing problem. Einstein's neighbor at Princeton, Kurt Godel, perhaps the greatest mathematical logician of the past 500 years, found a new solution to Einstein's own equations which allowed for time travel! The "river of time" now had whirlpools in which time could wrap itself into a circle. Godel's solution was quite ingenious: it postulated a universe filled with a rotating fluid. Anyone walking along the direction of rotation would find themselves back at the starting point, but backwards in time!"

"In his memoirs, Einstein wrote that he was disturbed that his equations contained solutions that allowed for time travel. But he finally concluded: the universe does not rotate, it expands (i.e. as in the Big Bang theory) and hence Godel's solution could be thrown out for "physical reasons." (Apparently, if the Big Bang was rotating, then time travel would be possible throughout the universe!)."

"Then, in 1963, Roy Kerr, a New Zealand mathematician, found a solution of Einstein's equations for a rotating black hole, which had bizarre properties. The black hole would not collapse to a point (as previously thought) but into a spinning ring (of neutrons). The ring would be circulating so rapidly that centrifugal force would keep the ring from collapsing under gravity. The ring, in turn, acts like the Looking Glass of Alice. Anyone walking through the ring would not die, but could pass through the ring into an alternate universe. Since then, hundreds of other "wormhole" solutions have been found to Einstein's equations. These wormholes connect not only two regions of space (hence the name) but also two regions of time as well. In principle, they can be used as time machines."

Time is both a concept and physical, it is a concept because it exists without being touched by anything, it is physical because we exist in it.

Though there are mathematical ways that may allow one to travel back in time, there is no real way to do that with any technology that we know of. Time is real. It is real just as space is real. We exist in the space-time continuum. In a relativistic universe, time is part of space-time. What is being debated is the nature of consciousness. And that is addressed elsewhere on the boards.

Certainly time travel does happen in a black hole, if we chose to look at it that way. It's possible in that time for the (unlucky or lucky?) traveler who sails in will slow down. It won't appear that way to that traveler, of course, but to the outside observer, things will be slowing up until those outside observers lose sight of the voyager making the trip into the unknown. Whether or not the person travels back in time, goes "through" the black hole and emerges somewhere and sometime else, or simply becomes part of the collection of matter at the bottom of the gravity well can be debated ad infinitum.

See the related question below. It is, "What is time?" It may help, or it may not.

Time is REAL, although it is an illusion, because of Einstein's General Theory of Relativity in where gravity can effect time. So you see, because of the Earth and it's mass, and the other large bodies of mass around us, it shapes our "time." If we were to go to a different planet, it would have a different "time" than our own. Where I am going with this, is that black holes have such immense gravity, that it would completely warp time around you, but they think that you can time travel in one.

It would have to be a rotating black hole so that the singularity would be ring shaped, because then it could be skipped, and thus (as is postulated) there would be an "Einstein-Rosen Bridge" that would put you into another time/universe. But, the bridge would always collapse right before entry, so you would be crushed into oblivion in the singularity.

Answer 2

yes but no, time exists in all of space, it's the 4th dimension of the universe. However, the immense amount of gravity (the product of space time distortion) makes time progress at a different 'speed'.

Answer 3

in my theory yes. on both sides of a black hole is "space" as in outer space the black hole will be traveling faster then light speed. it could be quadrillions of miles thick. taking millions of light years to travel through. but as it shoots you through its vortex you will have been shot through time at a speed faster then light. in your perspective going through the black hole could take 5seconds to someone on earth it takes billions of years if earth was to turn into a black hole and you went through it its possible that the solar system wouldn't even exist after you've been shot through it because of the loss of time. we call this a wormhole. when your shot through space in a fraction of a second to you but in reality it has taken billions of years. that is one of my theory that i have depicted on. wrap your mind around this and you can understand black holes and what happens. here is a easier way for kids to understand. when you bored time goes slow when you happy time goes fast. think of it as even thought you may be bored in the black hole your going at a happy speed Fast. again the wormhole takes seconds to shoot you through but slow in reality. black holes suck you in by gravity. if a black hole was to be a time machine who is to say our solar system isn't a big one and isn't sucking the entire series of planets sun to Pluto into it? maybe that's how we get our year where sucked into the black hole and in our time it feels like 365days but in the real space time continuum it has taken billions of years. please exploit my theory tell people. Jared idler grade 7 mental savant thanks for your time.

Answer 4

No. Theoretically, black holes lead to wormholes lead to white holes, but that's only one. Wormholes are also associated with teleportation in general.

Wormholes are probably the least considered concept in theoretical physics.

Answer 5

You are constantly going into the future, no matter what you do. All objects with mass slow down time, though most only do so to a very minor degree. Black holes, however cause significant time dilation. If you were to go near a black hole (though not actually enter it) you would see the universe outside the black hole go by faster, so you could, theoretically, you could go further into the future faster than you would experiencing time normally.

Answer 6

Its thought that no maybe there isn't ( someone input a good explanation why) but no ones even close to proving this because the workings of black holes is barely understood, itll take some mathematical breakthroughs, hopefully involving the existence of more theoretical dimensions, before solid theories about black holes can be established

Answer 7

Latest research in black holes hasn't brought up any space traveling we havent gone that far....................................yet.

Answer 8

It isn't known if there is time inside a black hole because no one has ever been close to one but it is likely that there is time inside them.

Answer 9

No, it's not true.

If you were to enter a black hole, you would die. Actually, you'd die well before reaching the event horizon.

Answer 10

no
