Heads up for Strange Signals from Outer Space! begins shortly (9pm) on Horizon on BBC2
Expecting wild theories about extra terrestrials and their advanced technology (massive solar sails etc) and tales of inter galactic travel.
Unlikely, I suppose, but it underlines how little we know about the universe and how imaginative our scientists can be!
I'm expecting good things from this, the last Horizon episode (Why Did I Go Mad) about psychosis was excellent.
