Can Time Travel Really Happen Through Black Holes?

Click For Summary
SUMMARY

The discussion centers on the relationship between time travel and black holes, specifically focusing on spinning black holes, which are described by the Kerr metric of spacetime. It is established that traveling through a spinning black hole could theoretically allow for time travel or transport to another location in the universe. The conversation also touches on the phenomena of wormholes and the concept of white holes, indicating a broader interest in the implications of these astrophysical entities.

PREREQUISITES
  • Understanding of Kerr metric in general relativity
  • Basic knowledge of black hole physics
  • Familiarity with concepts of time dilation and spacetime
  • Awareness of wormhole theories in astrophysics
NEXT STEPS
  • Research the Kerr metric and its implications for time travel
  • Explore the concept of wormholes and their theoretical underpinnings
  • Investigate the differences between black holes and white holes
  • Study the effects of traveling at near-light speeds on time perception
USEFUL FOR

Astronomy enthusiasts, theoretical physicists, and anyone interested in the implications of black hole physics and time travel theories.

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.
