Ok…so let’s say we make contact.

A professor at The University of California, Irvine weighs in on the notion.  Most of us have an internal curiosity about what other life forms would look like, act like and just making contact in general.  We do assume they would be friendly for the most part (unless you’re watching movies like Aliens and Predator).  One professor makes a case against the search:

The traditional assumption is that photos or other visual images are a universal language that any advanced life form could understand. In reality, it’s extremely unlikely that extraterrestrials would see things as humans do, says Don Hoffman, professor of cognitive sciences at the University of California, Irvine.

“The assumption that what we intend to communicate will be received as we intended it could be devastatingly dangerous,” Hoffman says.

Even on our own planet, eyesight varies widely, he notes. Bats perceive the world via radar. Indian pythons see in infrared. And honeybees navigate by detecting polarized light.

What do you think is it worth the risk?  And here is a video about SETI which darn near pioneered the field.
