Suppose two neutron stars or two black holes are closely orbiting one another. what do scientists predict will eventually happen to them, and why? suppose two neutron stars or two black holes are closely orbiting one another. what do scientists predict will eventually happen to them, and why?
a. their orbits will spiral inward until the two objects merge because of energy lost through gravitational waves.
b. their orbits will gradually grow larger because of the centrifugal force involved as they circle around each other.
c. the orbits would remain stable unless there were a third object orbiting along with them.
d. their orbits will spiral inward as a result of friction with the surrounding gas until all the gas clears, after which their orbits will remain stable.
