SUMMARY

This discussion explores the theoretical relationship between black holes and wormholes, suggesting that both phenomena exhibit similar local spacetime curvature, making them indistinguishable to outside observers. Participants highlight the speculative nature of these ideas, emphasizing that current scientific understanding does not confirm the existence of wormholes as portals to other universes. The conversation also touches on frame dragging, specifically the Lense-Thirring effect, which is associated with rotating black holes and is confirmed by the Gravity Probe B experiment.

PREREQUISITES
  • Understanding of black hole physics
  • Familiarity with wormhole theory
  • Knowledge of spacetime curvature concepts
  • Awareness of frame dragging and the Lense-Thirring effect
NEXT STEPS
  • Research the implications of spacetime curvature in general relativity
  • Study the Lense-Thirring effect and its measurements through Gravity Probe B
  • Explore theories on parallel universes and their relation to black holes
  • Investigate current advancements in wormhole research and theoretical physics
USEFUL FOR

Astrophysicists, theoretical physicists, and anyone interested in the intersection of black hole research and cosmological theories regarding the multiverse.

Could a black hole actually be either one of two things: a worm hole that leads to another universe or could a black hole be just another universe like for example our universe is within a black hole that's in a different universe??
 
Astronomy news on Phys.org
Could be. But we don't know (and at the present time cannot know) so any discussion would be purely speculative and therefor against forum rules.
 
Like negitron says, it's possible but we cannot know.

As I've said before in several threads, black holes and worm holes produce the same local spacetime curvature. So, to an outside observer, there is no way to tell the difference.

I thought there'd be frame dragging with a worm hole. Not so?
 
I'm pretty sure frame dragging applies to rotating black holes (any massive rotating object, really), never heard it applied to worm holes though.
 
Frame dragging, or the Lense-Thirring effect, occurs with any rotating object. It is, however, exceedingly small and difficult to measure. Gravity Probe B is the most recent attempt to confirm this prediction [which it did].
 
If you believe in parallel universes than these could well be the entrance to them!
