Can Time Travel Really Happen Through Black Holes?

AI Thread Summary
Time travel through black holes, particularly spinning black holes, is theorized based on the Kerr metric of spacetime, which suggests that specific paths could allow for backward time travel or teleportation to different locations. The discussion highlights the potential for traveling at near-light speeds to achieve these effects, although the feasibility remains speculative. The concept of wormholes is also mentioned, prompting inquiries about their nature and the existence of "white holes." While the information shared is intriguing and appears factual, further clarification on wormholes and white holes is requested. The exploration of these phenomena continues to captivate interest in the realms of physics and cosmology.

Hello friends,
Just some weeks before i read an article in a sci-tech magazine, which relates time travel and the black hole. The article said (although it looked quite absurd) that if one travels in a black hole, then he will reach in another part of the world, and if he goes with a speed nearly the speed of light, then he will reach in another part of the world as well as he willl travel time.
(I know it sounds funny)
But is this true
best regards,
Razi

This is about a SPINNING black hole. Such BH's generate what is called the Kerr metric of spacetime. If you followed just the right path through such a spacetime, you could exploit the tilting of lightcones to travel back in time. Or it has been asserted that if you follow a different path into the black hole you will wind up "someplace else" - nobody knows where.
 
Sometime ago I compiled parts from various sources covering that subject. Click the various links to find more information. Keeps you busy for a while. :wink:

Thanks

Thanks Madice this information was quiet interesting, and it proved to be quiet factual. but still can you explain a bit more of that wormhole phenomena. And can you please explain to me that are there some kinds of 'White holes' too.
 

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

Thread 'Can the signal WOW be explained by the maser effect?'

This hypothesis of scientists about the origin of the mysterious signal WOW seems plausible only on a superficial examination. In fact, such a strong coherent radiation requires a powerful initiating factor, and the hydrogen atoms in the cloud themselves must be in an overexcited state in order to respond instantly. If the density of the initiating radiation is insufficient, then the atoms of the cloud will not receive it at once, some will receive it earlier, and some later. But then there...
