BLACK HOLES: A MYSTERY OF THE UNIVERSE

By K.E. Chilton
93 Currie St.,
Hamilton, Ont.

Black holes! The very name conjures up a mystery! What is at the bottom of the hole? What causes a black hole ? What would happen if you fell into one? These questions and others provide one of the greatest mysteries of our Universe, one which has attracted much space in the newspapers, and one which has caused much discussion among astronomers.

by K.E. Chilton, F.R.A.S.

1. Daily apparent revolution:

Like all celestial bodies, the moon appears to revolve around the Earth, once every 24 hours. This is caused by the rotation of the Earth. However, the moon revolves eastward in its orbit, ie: in the same direction as the Earth. Therefore, it takes a little longer for the earth to catch up, lengthening the apparent revolution to 24h 50m.
