First, this community rocks. I only wish I could carry a conversation with some of the answerers, however this format is limited by (bad) design.
K, my question :
As I understand it. The universe is expanding. The further out we look, the faster the galaxies seem to be receding from us. There is a simple ratio involved : further out = faster speed of recession.There is also distance beyond which we can not see. My questions involves this distance.
Have any objects been seen, and can not be seen any more, because they are now beyond this distance?
Wouldnt objects beyond this distance be going (relative to us) faster than C?
If above is yes (seems likely to me) then an interesting side effect would be that we are able to get information about something going faster than light away from us. (gravitational pull of a galaxy near the edge, which could tell us how massive a nearby galaxy past the edge is)
I understand the frame dragging of a spinning Black Hole caused by the warping of time and space. Once the Schwarzschild radius has been reached is time actually moving backward? I understand that it's theoretically possible to move forward in time but I thought moving backward was deemed an impossibility.
