  I heard an astronomer say on an educational program just 2 days ago
that light does indeed have mass. The surface of the earth is bombarded
with roughly the equivalent of 2 pounds of light per day. This is of
course heresay and would not hold up in a court of law. The program
that I heard this on a is called "Universe: The Infinite Frontier"
which airs on a local public broadcast station (PBS).
