YES, BLOGGING HAS BEEN LIGHT: Today is root canal day. Recovering OK but not blogging much for a bit.
Meanwhile, note that Stephen Hawking is once again calling for space colonization:
Humans must colonize planets in other solar systems traveling there using “Star Trek”-style propulsion or face extinction, renowned British cosmologist Stephen Hawking said on Thursday.
Referring to complex theories and the speed of light, Hawking, the wheel-chair bound Cambridge University physicist, told BBC radio that theoretical advances could revolutionize the velocity of space travel and make such colonies possible.
“Sooner or later disasters such as an asteroid collision or a nuclear war could wipe us all out,” said Professor Hawking, who was crippled by a muscle disease at the age of 21 and who speaks through a computerized voice synthesizer.
“But once we spread out into space and establish independent colonies, our future should be safe,” said Hawking, who was due to receive the world’s oldest award for scientific achievement, the Copley medal, from Britain’s Royal Society on Thursday.
Bring it on.
