The human race must move to a planet beyond our Solar System to protect the future of the species, Professor Stephen Hawking has warned. “Once we spread out into space and establish colonies, our future should be safe”. He said there were no similar planets to Earth in our Solar System so humans would "have to go to another star". Hawkings said that current chemical and nuclear rockets were not adequate for taking colonists into space as they would mean a journey of 50,000 years. He also discounted using warp drive to travel at the speed of light for taking people to a new outpost. Instead, he favoured "matter/anti-matter annihilation" as a means of propulsion. "When matter and anti-matter meet up, they disappear in a burst of radiation. If this was beamed out of the back of a spaceship, it could drive it forward." Travelling at just below the speed of light, it would mean a journey of about six years to reach a new star.
What chance London’s Metronet can get us moving into space?!!!!!
