Time variation in the event horizon

Click For Summary
SUMMARY

The discussion centers on the phenomenon of time variation near a black hole's event horizon, specifically addressing the concept of time "freezing" as perceived by distant observers. It is established that this effect is not experienced by an object falling into the black hole; instead, the object accelerates towards the singularity due to gravitational forces. The conversation also touches on alternative methods for detecting black holes beyond observing stellar movements, emphasizing the unique physics involved in such extreme environments.

PREREQUISITES
  • Understanding of general relativity and its implications on time perception
  • Familiarity with black hole physics, particularly event horizons and singularities
  • Knowledge of gravitational effects on objects in extreme environments
  • Basic concepts of condensed matter physics as it relates to atomic behavior
NEXT STEPS
  • Research the implications of general relativity on time dilation near massive objects
  • Explore the methods of detecting black holes, including gravitational wave astronomy
  • Study the effects of gravity on time and motion in extreme gravitational fields
  • Investigate condensed matter physics and its relevance to black hole environments
USEFUL FOR

Astronomers, physicists, and anyone interested in the complexities of black hole dynamics and the nature of time in extreme gravitational fields.

i haven't yet got this concept. i have read about the time "freezing" near a BH , but am not clear. can u please explain what actually happens? why does the time stop? i also want to know one thing-- when, supposing 'A' enters the event horizon he moves slowly towards the singularity because of the time. but isen't gravity stronger? so shoulden't he move faster? oh one more thing, is there any other way of detecting a black hole other than the movement of stars?

The "freezing" of time is in the frame of a distant observer. Anyone falling into a black hole will not see such an effect, but will speed up due to gravity.
 
Agreed. The 'freezing' effect is what a remote observer sees. Your clock ticks away unfazed as the black hole gives your atoms a crash course in condensed matter phyics...
