What We Still Don't Know Are We Alone




3 parts

In Are We Alone?, Martin Rees puts paid to the flights of fantasy and takes us on a journey of unsettling consequence. Seth Shostak is one of SETI?s (Institute for the

Search for Extra Terrestrial Intelligence) leading investigators. He is utterly convinced that there is someone out there. The most compelling evidence is simply in the vast

scales of space. There are 10,000 billion billion stars visible from Earth?s telescopes alone, and a conservative estimate places orbiting planets around one in ten of them.

Would it not then be very strange if Earth were the only planet out of so many boggling billions to have been a cradle for life?
