Falling Into a Black Hole: Time Dilation & Survival

In summary, it is not possible for an observer falling into a supermassive black hole to survive until the end of the universe due to the effects of time dilation. Despite appearing to slow down and become increasingly red to an outside observer, the infaller experiences a rapid increase in the speed of the universe. This ultimately leads to their demise as they reach the central singularity and are destroyed by hawking radiation. Previous discussions and research have confirmed this fate for the infaller.

So for an outside observer it appears someone falling into is slowing down and then gets redder and redder. But what about for the local observer? From the perspective of the person falling I would imagine that the universe would appear to speed up tremendously. Is it possible you could survive to the end of the universe since time dilation becomes more pronounced the closer you get? Like is it possible that what kills you is the hawking radiation which eventually destroys a black hole and not as you would think the gravitational difference spaghettifying you?

Also I am referring to a supermassive black hole.

No. There are many threads here already about the infaller's experience: He crosses the event horizon and very shortly after that reaches the central singularity and dies horribly; the last thing he sees is light that crossed the event horizon shortly after he did.

Search for some of the older threads, or you can try this paper - even if the math is somewhat daunting, the English prose around the math is somewhat accessible to a layman.
 

Related to Falling Into a Black Hole: Time Dilation & Survival

1. What is a black hole?

A black hole is a region in space where the gravitational pull is so strong that nothing, including light, can escape from it. This is because the mass of a black hole is so concentrated that it warps the fabric of space-time around it, creating a one-way path towards the center.

2. What is time dilation in relation to black holes?

Time dilation is the phenomenon where time moves slower in the presence of a strong gravitational field, such as that of a black hole. This is due to the warping of space-time, which causes time to pass at different rates depending on the strength of the gravitational pull.

3. Can someone survive falling into a black hole?

No, it is not possible for a person to survive falling into a black hole. The immense gravitational forces would stretch and compress the individual, a process known as "spaghettification", before they reach the center of the black hole where they would be crushed by the singularity.

4. What happens to time inside a black hole?

Inside a black hole, time essentially stops. This is because the gravitational pull is so strong that the laws of physics as we know them break down, including the concept of time. The closer you get to the singularity at the center of a black hole, the slower time moves.

5. Is there any way to escape a black hole?

Currently, there is no known way to escape a black hole once you have crossed the event horizon, the point of no return. However, there are theories about potential ways to escape using advanced technologies or wormholes, but they have not been proven or tested.
