Can Time Travel Really Happen Through Black Holes?

Click For Summary

Discussion Overview

The discussion centers around the concept of time travel through black holes, particularly focusing on the theoretical implications of black holes and their properties, such as the Kerr metric and wormholes. Participants explore various ideas related to time travel, the nature of black holes, and the possibility of reaching different locations in spacetime.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant references an article suggesting that traveling into a black hole could allow for time travel and reaching different parts of the universe, although they express skepticism about its validity.
  • Another participant discusses the properties of spinning black holes, specifically the Kerr metric, and proposes that following certain paths could enable time travel or lead to unknown locations.
  • A participant mentions compiling various sources on black holes, singularities, and wormholes, indicating a breadth of information on the topic.
  • One participant expresses interest in further explanation about wormholes and inquires about the existence of 'white holes'.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the feasibility of time travel through black holes, and multiple competing views regarding the nature and implications of black holes and wormholes remain present.

Contextual Notes

Some claims depend on specific theoretical frameworks, such as the Kerr metric, and the discussion includes unresolved questions about the nature of wormholes and the concept of white holes.

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.
