If you fell into a black hole, you would experience time to be running normally as you plunged rapidly across the event horizon. B. A spaceship passing near a 10 solar mass black hole is much more likely to be destroyed than a space ...

This implies that stars that are born in the center of a cluster have a greater opportunity to reach higher masses. This is part ...
