Is a black hole a wormhole like as in time travel?

Answer 1

some thing there might be a wormhole connection between blackholes, but nobody can prove wormholes yet.

and no one can travel into a blackhole to prove it.

but black holes are real and almost ALL galaxies have one in their center.

Answer 2

Its a dead end. But astronomers say that its a time traveler.






A black hole is a region of space whose gravitational field is so powerful that nothing can escape it once it has fallen past a certain point, called the event horizon. The name comes from the fact that even electromagnetic radiation (i.e. light) is unable to escape, rendering the interior invisible. However, black holes can be detected if they interact with matter outside the event horizon, for example by sucking in gas from an orbiting star. The gas spirals inward, heating up to very high temperatures and emitting large amounts of radiation in the process.

While the idea of an object with gravity strong enough to prevent light from escaping was proposed in the 18th century, black holes as presently understood are described by Einstein's theory of general relativity, developed in 1916. This theory predicts that when a large enough amount of mass is present within a sufficiently small region of space, all paths through space are warped inwards towards the center of the volume, forcing all matter and radiation to fall inwardly.

While general relativity describes a black hole as a region of empty space with a pointlike singularity at the center and an event horizon at the outer edge, the description changes when the effects of quantum mechanics are taken into account. Research on this subject indicates that, rather than holding captured matter forever, black holes slowly leak a form of thermal energy called Hawking radiation.However, the final, correct description of black holes, requiring a theory of quantum gravity, is unknown.

Answer 3

I don't know much about wormholes, but black holes have a gravitational field so powerful that if you slid towards a black hole feet first, the effect of gravity would be greater on your toes than on your head. So theoretically as you approach the singularity of the black hole your body begins to get ripped apart, first your toes gets sucked off, then your feet, then your shins, then your legs, then your pelvis, your torso, your neck and finally your head all separate and accelerate towards the singularity in a stream on condensed atoms.

So if a black hole is a rip in the fabric of space time that would allow someone to time travel, chances are it would be a trip that you don't want to make...

Answer 4

LOL @ Dan S on his dissertation on black hole physics. No one cares to read 3 pages of mumbo jumbo.

It is impossible to survive a black hole. Gravity is reaching a point almost to infinity, every cell in your body would be torn apart, no matter what type of ship you had.

A wormhole is theoretical, it has not been proved. Also there is no proof that time has ever gone backwards. Relativity hints at time/space being curved, but whether you can actually curve it so much that time goes backwards is really reaching.

Answer 5

I have heard (but i can't remember where) that some scientists believe the cloud galaxies could be the output of black holes gravitational pull distributed through a wormhole.

Answer 6

You wouldn't live to find out. If you traveled to a black hole, you might glimpse something once you were on the horizon, but you wouldn't have time to send anything back to earth. 1) The transmission wouldn't escape the black hole's gravity either. 2) Three seconds later you would be crushed and incorporated into the entire mass of the star. The little pieces of you might travel to a new time, but you'd be dead, so it wouldn't matter.

Answer 7

A black hole is a collapsed supermassive star, a wormhole is a hypothetical shortcut from one place to another. check out wikipedia for both.

Answer 8

When a star undergoes a supernova (when a star explodes and dies), the matter left behind is drawn into it's core and compressed. It continues to collect matter as it goes along. The compression is so great that it would equate to crushing all the cars in the world into a thimble.
So, my answer is "no". If you went into the black hole you'd probably end up like one of those cars in the thimble!

Answer 9

No, a black hole is a dead end not a wormhole.

A black hole is pure gravity, a point in space with all the matter of a huge star condensed to this point. This is impossible in the universe as we know it so inside of a black hole the laws of physics break down. However, we can't see inside a black hole. At some point; called the Schwarzschild radius, the particles moving into it are going at the speed of light. Since nothing can go faster than the speed of light, any information inside of the Schwarzschild radius, also called the event horizon, would be unknown and unknowable.

There is a law of the conversation of information that says that information in the universe has to be conserved, just like matter and energy. Black holes defied this law because what ever falls into a black hole is gone and can’t be observed again. Steven Hawking didn’t like this and postulated the idea of Hawking Radiation. It was discovered that indeed black holes emit this Hawking radiation so what goes into a black hole might come out at some point, but it would be broken down to the most basic fundamental forms of the universe. Getting information out this way would be difficult at best; most likely impossible.

According to those like Steven Hawking the space near a rotating super massive object, like a black hole would be stressed. If the black hole was orbiting in a circle then anything going through the center of that circle would travel into distorted time space allowing time travel into the past. Up to the point where this rotating black hole still exists. I don’t understand the math and I don’t claim to understand all the physics, nor do I know how you would navigate in time. Currently we don’t know of any spaceship that could survive those conditions of stressed space time. So time travel may not be possible. The conditions could be impossible to create or the area of stressed space time could be so unstable that nothing could survive passage through it. If this is true, and I think it is, then history would be safe and unchangeable. If not then who knows what could happen.

A wormhole is an entirely different concept related to string theory. My answer on that can be found here: http://answers.yahoo.com/question/index;_ylt=As8neXl0gWtZgH4WFYVje2zsy6IX?qid=20070815001346AAHzeLt&show=7#profile-info-ICLbMWUjaa.

With a wormhole travel from the start to the finish would be in an instant. This would allow us to cross huge areas of space by taking a short cut around it. String theory says that in the world of Quantum Physics the universe at this level is unstable; like foam on a cup of espresso. This foam could be made up of tiny wormholes; strings. The string would be the distance between each wormhole, and the connection to each other. However, this is only a theory, but it is the one most accepted by current physics. To work though it requires that there be at least 20 dimensions; since we are limited to understanding the basic four dimensions (depth, length, width, and time) we may never know the truth. But, if we could harness the strings and combine enough of them going to the same place then we could take a short cut travel across space in an instant.

At one time black holes were thought to be wormholes with “white holes” at the other end. Maybe these “white holes” could be something as powerful as a quasar? However, we have since discovered that quasars are actually black holes. They have one pole pointed in our direction so we see the massive gamma ray bursts caused by objects trying to enter the black hole. Objects fall into a black hole at the same speed, at the equator there is a lot of space for the objects to fall. At the poles the “mouth” of the black hole is narrower. When the matter being absorbed by the black hole starts to crash together it destroys itself creating a huge burst of x-rays and gamma rays; a gamma ray burst.

Black holes are dead ends that store matter and eventually evaporate through Hawking Radiation (http://en.wikipedia.org/wiki/Hawking_Radiation). Worm holes are products of string theory that, if possible would allow instantiously traveling from one end of the string to the other. Time travel is different, but black holes could create the required area of stressed space time.

Time travel navigation could be impossible. There is a theory that says that for ever decision all versions of that decision are created; along alternate time lines. When you get down to the quantum level where electrons are found in clouds of probability the number of decisions are infinite; so traveling back in time and then returning could be very difficult.

If you go back in time and kill your grandfather; the famous “grandfather paradox” then what happens to you? Do you return to a time line where you were never were born, or do you cease to exist, or does time conspire to not allow you to kill your grandfather? These solutions could explain why there are no time travelers talking to us today.

Answer 10

Unknown - we'll put your name down for the first ship to try.
