Huh, anyone else hear about this? I thought it was just speed - the faster you go the slower time gets because of the constant perceived speed of light. Apparently gravity effects time as well because the "local effects of gravity are the same as those of being in an accelerated frame of reference".

I was familiar with it, oddly enough, from a SciFi film.

 

The ending of the film Sunshine tried to portray it. (spoilers, of course)

Here's the next question.

How do blackholes become larger, if matter passing though the event horizon becomes frozen in time?

Yeah, known for a while now. They have to re-adjust the GPS network clocks every so often because they go out of sync with Earth time.

Time isn't universal. It's reference dependent. To an outside observer it may look like time is 'frozen' but to the matter falling into the black hole, time continues normally.
 Not sure if that's clear, but that's the gist of it. Basically, time doesn't stop for an object falling into the black hole.

Ah, so that's why when someone tells me that I don't understand the gravity of the situation, that time seems to go really slowly.
