Discussion Overview

The discussion revolves around the behavior of light in the vicinity of a black hole, particularly focusing on whether light pointed directly at a black hole will be absorbed or if it can bend around it. The scope includes conceptual understanding and implications of gravitational effects on light.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant questions whether light aimed directly at a black hole will be absorbed or if it will bend away due to gravitational forces.
  • Another participant asserts that light pointed directly at a black hole will enter and not return, while light aimed slightly off may bend and potentially return.
  • A third participant introduces the concept of Einstein rings as an example of gravitational lensing, suggesting that light can be affected by black holes without being captured.

Areas of Agreement / Disagreement

There is some agreement that light can behave differently depending on its trajectory relative to the black hole, but the discussion reflects differing interpretations of how light interacts with the event horizon.

Contextual Notes

The discussion does not resolve the nuances of light behavior near black holes, including the specific conditions under which light may bend or be captured.

hi guys, i have an elementary question about the black hole..recently i have read in a science magazine that even the lights from other stars can not reach to the black hole ( event horizon) rather bends in other direction due to its gravitational force..now my question is if i point a light source towards a black hole , will it not hit the black hole (event horizon ) and never return to me ? or it will just bend tangent to the horizon and go to some other space ...

previously i thought black holes just grab light and never returns it ...but grabs actually...is it wrong thinking ?
please help me
regards

You had it right: the light will enter the black hole and never return, if it is pointed right at the black hole. If the light is pointed next to the black hole, it may loop back around and return to you (or go in another direction).
 
thanks a lot.. now i can ask the author of the paper how he mentioned it ..
