If you launch two probes in opposite directions from the Space Station,they will meet as they orbit Earth.According to general relativity,why does this happen?
A)They are following the straightest possible paths through space time,but those paths happen to meet.
B)They are following the allowed orbits according to Newton's universal law of gravitation.
