The Harvard-Smithsonian Center for Astrophysics and Harvard Origins of
Life Initiative are sponsoring a landmark two-day symposium May 1-2,
“Crossroads: The Future of Human Life in the Universe.” It is part of
the Cambridge Science Festival and commemorates the 2009 International
Year of Astronomy. The conference, which is open to the general
public, will feature a series of lectures by scientific luminaries.

About the Symposium:

Astronomers are on the threshold of discovering the Holy Grail of
planetary sciences: new Earth-like planets. The next challenge will be
to determine whether or not these worlds have life on them –
especially intelligent life that we can communicate with.

If such life does exist beyond our solar system, will it be
technologically based life like ours? Or, if we do not find
intelligent life out there, what does that imply about our place in
the Universe?

Are there “filters” like global warming, overpopulation, exhaustion of
natural resources, and the emergence of AI that sentient species must
pass through? And, if they don’t, does their dominance end? Is this
the reason SETI has heard nothing for the past 35 years – because no
intelligent species near us has survived these types of filters?

Are humans on the brink of one of these dangerous passages right now?
These are the topics to be explored in this provocative meeting of
world experts as we examine the possible future of human life in the
Universe.
