How Do Black Holes Exert Gravity If They Absorb Light?

Click For Summary
SUMMARY

Black holes exert gravity despite absorbing light due to their immense mass and the curvature of spacetime they create. According to the Usenet Physics FAQ, the gravitational influence of a black hole extends beyond its event horizon, allowing objects outside to be affected by its gravitational pull. This phenomenon does not imply that anything can move faster than light; rather, it highlights the complex nature of gravity in the context of general relativity.

PREREQUISITES
  • Understanding of general relativity
  • Familiarity with the concept of spacetime curvature
  • Basic knowledge of black hole physics
  • Awareness of the event horizon concept
NEXT STEPS
  • Research the principles of general relativity and its implications on gravity
  • Explore the concept of spacetime and how mass influences its curvature
  • Study the characteristics and types of black holes
  • Investigate the nature of light and its interaction with gravitational fields
USEFUL FOR

Astronomy enthusiasts, physics students, and anyone interested in understanding the fundamental principles of black holes and gravity.

Hi friends,.
If black holes absorb light also, how can it exert any gravity outside a particular region? Or something can move faster than light?

This answer from the "black holes" section of the Usenet Physics FAQ addresses that question.
