Big Rip Theory & Black Holes: Relativity Explained

[Surya Suresh]

According to the Big rip theory if Black holes tear apart after a very long time, then according to the theory of relativity an object that reaches the event horizon should see time passing infinitelty and by the time the object was swallowed wouldn't the black hole not exist anymore because of the big rip?

Do you have a reference for why you think there is a "big rip" theory that says this?

an object that reaches the event horizon should see time passing infinitelty

This is a common error, unfortunately perpetuated by pop science sources. It comes from trying to apply the standard formula for gravitational time dilation to an object on the event horizon, where the assumptions underlying the formula are invalid. An object falling through the event horizon will not see the whole history of the universe. It sees very little after it falls through the horizon, which it does in finite time by its own clocks.
