Hot Science - Cool Talks #33
Dr. Wallace Fowler
November 19, 2004

Presented by the Environmental Science Institute as part of Hot Science - Cool Talks.

Outer space is a topic that easily captures the human imagination. But whether we are thinking about satellites circling the Earth or Star Trek, most people have at least a few misconceptions about space and space travel. This talk takes a close look at some of these misconceptions and myths. The misconceptions do not stand up if we apply physical and biological science to the problems or if we look at the economic realities of space exploration. For example, it is difficult for us to comprehend the real reason a person would be “weightless” while in orbit, having spent our lives securely stuck to the Earth by gravity. Most of us also have difficulties grasping the economics of sending people or satellites into space when the sums involved are in the many millions of dollars. Some myths about space, like those about space aliens and UFOs, are simply the result of wishful thinking or a desire for exciting, exotic explanations of ordinary events. A clear understanding of the exciting scientific and engineering challenges of outer space helps us gain new knowledge and improve our lives on Earth.
