Amen. Space-time has got to be the most fascinating concept to think about.
Like how if something is approaching a black hole, once it reaches the event horizon, it would appear to be frozen in time at the event horizon, even though it would have been sucked into the hole in an instant.
The event horizon is the last point at which light can escape the gravitational pull of a black hole. Once you pass that point, even light gets pulled in.
At the event horizon, light moves so slowly away, that the light traveling away from an object there takes forever to get past an outside observer. Giving the appearance of being frozen in time.
I love it.
