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.
 
Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...
