Is Change Possible Without Time and Vice Versa?

It describes some serious medical complications and a mother to whom you should be very, very grateful...

Not really. Put it this way. Let's say you fell and skinned your knee. The tissues there are damaged and torn open. The next few weeks are spent by the surrounding tissues healing and repairing the torn tissue Once that tissue has been restored, it is much younger tissue than the surrounding tissue. So here the time reference for the new tissue is different from the timeframe/reference of the old, surrounding tissue. But, I doubt there is a "time dilation".

Time dilation refers to the old spaceship parked beside a black hole with a video camera trained on a clock in the space ship. There is also a monitor showing a clock on earth. The clock in the spaceship by the black hole is not moving where as the monitor shows the clock on Earth moving, somewhat rapidly, in relation to clock on the rocket ship.

What is it about gravity that does this to our sense of time/change?

I can give you a brief answer to this question, but your other questions regarding time dilation and tissue damage should probably be asked in a new thread in the relativity forum.

Gravity is acceleration. Experiments producing differential time accumulations (differential 'aging') suggest that acceleration increases the periods of oscillators (thus decreasing the accumulation of oscillations, or slowing the aging process). The physical mechanism wrt how this happens is unknown.

So this is why approaching and going the speed of light apparently causes the same effect... acceleration?
