Double-A You are explaining gravities ability to curve space. Time is
related to density. and great mass density can bring time to a stop. In
the case of black holes at the right distance from its center you can
be in an area that has very slow time flow, If you parked your space
ship for a year there when you got back to Earth 100,000 Earth years
would have past. If you were going around this black hole at a
speed of 99.999999999999999999 of 'c' 200.000 Earth years would have
past. Best to keep in mind both velocity,and gravity control the flow
of time. Best to keep in mind time obeys the inverse square law. bert
