gravity

Interview on WNYC's Brian Lehrer Show about life, the Universe, and everything.

An exposition of all the ways objects can move under the influence of gravity.

The meaning and consequences of universal constants that do not change in time or space.

A conversation with WNYC's Leonard Lopate on extremophiles, life in the universe, water in the Solar System, and the evolving scientific frontier.

In a system of two objects in mutual orbit, five points in space exist, in orbit with them, where all forces cancel. These spots make great places to erect space colonies and to otherwise collect and assemble space hardware.

Why does nature tend to create round objects?
