Time variation in the event horizon

In summary, the "freezing" of time near a black hole is a concept that is observed by a distant observer. However, for someone actually falling into a black hole, time would not appear to stop, but rather would speed up due to the strong gravitational pull. This effect is caused by the intense gravity of the black hole, which can also be used to detect its presence through the movement of stars. Additionally, falling into a black hole would also result in a crash course in condensed matter physics for the individual, as their atoms are compressed by the intense gravity.

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...
 

Related to Time variation in the event horizon

1. What is the event horizon?

The event horizon is a theoretical boundary surrounding a black hole, beyond which nothing, not even light, can escape due to the intense gravitational pull.

2. How does time vary in the event horizon?

According to Einstein's theory of relativity, time slows down in areas with strong gravitational fields. Therefore, time would appear to slow down for an outside observer looking at the event horizon of a black hole.

3. Can time travel occur in the event horizon?

No, time travel is not possible in the event horizon. The time dilation effect only applies to outside observers and does not allow for actual travel through time.

4. Does the size of the black hole affect time variation in the event horizon?

Yes, the size of the black hole does affect time variation in the event horizon. The larger the black hole, the more intense the gravitational pull, and the greater the time dilation effect.

5. How does the theory of general relativity explain time variation in the event horizon?

The theory of general relativity explains time variation in the event horizon through the concept of gravity warping space-time. The intense gravitational pull of a black hole causes a distortion in space-time, affecting the flow of time near the event horizon.
