I think you misunderstood what I said. The physics thread guy said that gravitational time dilation of a mass approaching an event horizon is identical to the the time dilation experienced by an object traveling at velocity approaching c. I mean comparing them as analogues, not that the gravitationally dilated mass is also experiencing SR effects.
This doesn't intuitively seem correct to me. The principle of equivalence only relates gravitational acceleration to actual acceleration, right?
Anyway this seems like an easy thing to check mathematically. Isn't there a simple formula for the amount of common time elapsed per second in a gravitational field of X strength? What strength does that need to be in order for time dilation to be infinite?
Re: my instantaneous usage, what I meant was that from the point of view of a being approaching the EH, a nanosecond of time would be equal to trillions of years of common time outside of the gravitational field of the black hole.
