... According to Einstein, a pair of black holes orbiting each other emit gravitational waves causing them to gradually approach each other over billions of years. Gravitational waves are produced during the final fraction of a second before the merger of the two black holes. During the merger, the blac ...

Honors Question – Black Holes and Neutron Stars In Friday`s lecture
... In Friday's lecture, we learned that physicists think that black holes are mass singularities – an enormous mass concentrated in essentially a point. Since gravitational force increases as the distance decreases, it's natural to conclude that within some radius the gravitational force is so large th ...
