Cosmic Truth at the Bottom of the Sea

From time to time I really enjoy the “gee whiz” factor of science and technology issues. I was listening to NPR’s  “Talk of the Nation Science Friday” as the guests discussed robotic submarines to explore the depths of the Arctic Ocean. They are looking for hydrothermal vents, where the earth spews out gases and minerals at incredible sea depths.

Some life forms have developed at the vents. So you wind up with life that has no access to sunlight-produced food or free oxygen. This leads to a stunning question: if this can happen at sea depths, could it explain non-oxygen based life forms in outer space?

If you wish to hear more, here’s the link to the show’s audio:

 Science Friday airs weekly from 2PM to 4PM. Great way to expand your thinking.
