Discovery Science Ultra Science Time Travel.flv

This show discusses the aspects and possibilities of time travel. If, for instance if one where to travel faster than the speed of light – they would be traveling backwards in time. But, since they gain more mass as they reach light speed, he would be obliterated by his own gravitational field. Questions such as quantum loopholes and wormholes raise eyebrows as exceptions to the theories devised by Einstein in the 20th century. Does time travel back in time create irreversible effects, such as the grandfather paradox, or does each change create a new world line in which another parallel universe is created? Explore sci-fi ideas inspired by Star Trek, and the ideas given from Steven Hawking’s book ‘A Brief History of Time‘.
