The discussion centers on the relationship between the Big Rip theory and black holes, specifically addressing misconceptions about time perception at the event horizon. It clarifies that an object crossing the event horizon of a black hole does not experience time passing infinitely, contrary to popular belief. Instead, gravitational time dilation does not apply as expected at the event horizon due to invalid assumptions in the standard formula. The conversation emphasizes that an object falling into a black hole perceives its fall in finite time, not witnessing the entire history of the universe.
PREREQUISITESAstronomers, physicists, and students of theoretical physics seeking to deepen their understanding of black holes and cosmological theories, particularly those interested in the intersection of general relativity and cosmic evolution.
Surya Suresh said: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?
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.Surya Suresh said:an object that reaches the event horizon should see time passing infinitelty
