How cant EM wawe escape from a black hole?

Click For Summary

Discussion Overview

The discussion revolves around the question of how electromagnetic (EM) waves can escape from a black hole, focusing on the theoretical implications of general relativity and the nature of spacetime. Participants seek to understand the underlying principles and seek resources for further reading.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant requests scientific papers or books to better understand the behavior of EM waves in the context of black holes.
  • Another participant suggests the book "Exploring Black Holes: Introduction to General Relativity" by Taylor and Wheeler as a resource.
  • A participant proposes that EM waves cannot escape a black hole due to the bending of spacetime, arguing that the inability to escape is not dependent on the mass of the waves.
  • Another participant agrees with this viewpoint, stating that black holes are a prediction of general relativity, emphasizing that only the curved space of general relativity allows for the trapping of light.

Areas of Agreement / Disagreement

There is a general agreement among some participants regarding the concept that EM waves cannot escape a black hole due to the curvature of spacetime, but the discussion does not resolve all aspects of the topic.

Contextual Notes

The discussion does not address specific mathematical formulations or detailed mechanisms of how EM waves interact with black holes, leaving some assumptions and definitions unexamined.

i need to have some scientific papers about this. I understand the massive ones
but i can't understand it when it comes to a EM wawe. Can anyone advice me a book or a paper ?

Try the book Exploring Black Holes: Introduction to General Relativity by Taylor and Wheeler.

Thank you dude.

I got a point while i was thinking about it later. Can you say if i thought the right way?

It can't escape because it is not about the particle , because of the bending of the spacetime . So if there is no exit, it doesn't matter if you have mass or not
 
That is exactly correct. In fact, Black Holes are often referred to as "a prediction of General Relativity," because only the curved space of GR makes the trapping of light possible.
