Penrose has been studying CWB radiation and believes it's possible that space and time did not come into being at the Big Bang but that our universe in fact continually cycles through a series of "aeons". He believes that he has found evidence supporting his theory that the universe infinitely cycles, which contradicts current theory.
EADS Astrium says the satellite system would collect the Sun's energy and transmit it to Earth via an infrared laser, to provide electricity. Space solar power has been talked about for more than 30 years as an attractive concept because it would be "clean, inexhaustible, and available 24 hours a day". However, there have always been question marks over its cost, efficiency and safety. But Astrium believes the technology is close to proving its maturity.
