Small comet controversy flares again

Atmospheric scientists report finding further evidence supporting the controversial theory that tens of thousands of small comets bombard the Earth each day. The researchers have detected apparent signs of water vapor from the comets in an extremely dry portion of the atmosphere about 80 kilometers above the Earth.

John J. Olivero and his colleagues at the Pennsylvania State University at University Park monitored the sky with a microwave radiometer that can detect extremely weak emissions from gases high in the atmosphere. Out of more ...
