How Can Black Holes Defy Einstein's Theory of Gravity?

Click For Summary
SUMMARY

This discussion centers on the apparent contradiction between Einstein's theory of relativity and the behavior of black holes regarding gravity. Participants highlight that while Einstein posits gravity propagates at the speed of light, black holes exhibit gravitational fields that challenge this notion. A key quote from the referenced source states, "Once formed, they and their gravity just are," suggesting that black holes may operate under principles beyond traditional gravitational forces. This indicates a need for further exploration into the nature of gravity in extreme conditions.

PREREQUISITES
  • Understanding of Einstein's theory of relativity
  • Familiarity with the concept of black holes
  • Knowledge of gravitational propagation
  • Basic grasp of quantum mechanics and gravitons
NEXT STEPS
  • Research the implications of black holes on general relativity
  • Explore the concept of gravitons and their role in gravity
  • Investigate alternative theories of gravity beyond Einstein's framework
  • Study the effects of extreme gravitational fields on spacetime
USEFUL FOR

Astronomers, physicists, and students of theoretical physics interested in the complexities of gravity and black hole phenomena.

Einstein’s relativity states that gravity propagates at the speed of light.
How can a black hole have a gravitational field when gravity propagates at the speed of light?

Wow! thanks for the insight and reference, and wonderful quotes.
I thought it was of particular interest that the phrase "Once formed, they and their gravity just are." was used. ?
No gravitons would be available, if gravity was not a force; but the effect was from another (non-force) cause.
thanks again
