Light Shines Through
From the National Space Society: The team of Stanley Von Medvey, Mike Snead, and NSS Governor Howard Bloom produced this video as a message for the next US President. In late June Colonel "Coyote" Smith announced the first solar power demo from Space. Legally it will be a student project, which gets around a lot of regulations! Japan is also working seriously on SSP. The International Space Station has given humans experience building big things in Space. The dream of clean power from Space may finally be moving forward.
Another interesting comment from Canada has been found following Lawrence Krauss' December article at Physicsworld.
"Riofrio claims that the speed of light varies with time. Very simply – perhaps too simply – I understand that her reasoning goes something like this. In Plank units we can write (assuming a locally flat universe) the rest energy of a mass m as:
E = GmM/R…(1)
"But R the distance to a mass M having the equivalent mass of the universe and R=ct, where t is the age of the universe (t=time since the big bang), E = mc^2 so that:
mc^2 = GmM/(ct). Thus tc^3 = GM implying that c is a function of time.
"If Riofrio’s interpretation is correct, light is slowing down and thus the measured supernova redshift does not necessarily indicate an accelerating expansion of the universe; hence no Dark Energy is needed! I would appreciate your comment on this line of reasoning."
UPDATE: In case anyone wonders who came up with "GM=tc^3" theory, another short paper from 2005 is available for sale at the British Library website.
