Thus we can conclude that our past light cone must pass through a certain amount of matter as one follows it back. This amount of matter is enough to curve space-time, so the light rays in our past light cone are bent back toward each other.

As one goes back in time, the cross sections of our past light cone reach a maximum size and begin to get smaller again.

Our past is pear-shaped.
