From Mars to the multiverse: life, space and the cosmos
Ζωντανή μετάδοση στις 24 Φεβ 2016
Unmanned
spacecraft have visited the other planets of our Solar System (and some
of their moons), beaming back pictures of varied and distinctive worlds
- but none propitious for life.
But prospects are far more
interesting when we extend our gaze to other stars: most stars are, like
our Sun, orbited by retinues of planets. Our home galaxy contains a
billion planets like the Earth. Will post-humans one day visit some of
them? Or are they inhabited already? If so, are the 'aliens' organic or
'AI'.
Moreover, our Galaxy is one of billions visible with a
large telescope, which are all the aftermath of a cosmic 'big bang' 13.8
billion years ago.
More astonishing still, 'our' big bang may
not have been the only one, but merely a member of a vast (perhaps
infinite) ensemble.
This illustrated talk will address these
topics, and what this perspective means for the long-range future of
intelligence in the cosmos. Lord Rees will emphasise that the remarkable
advances in our science in recent decades are essentially owed to new
engineering and technology. Armchair theory alone doesn't get us far!
