New Thinking on Time Travel

Astrophysicists pondering the subject of time travel have postulated not only whether time travel is theoretically possible but whether it is technically achieveable. The popular concepts using black holes, wormholes, and cosmic strings are not practically possible because they basically require the ability to harness energy equivalent to an exploding star and an inconceivable amount of mass. A more down-to-earth concept has been proposed. Physicist Ronald Mallett is known for his expertise in general relativity, gravitation, black holes, relativistic astrophysics, and quantum cosmology. He has been working with Einstein’s equations for years in an attempt to design a sort of time machine. Professor Mallett has devised an alternative to these time travel methods based on Einstein’s famous relativity equation: E=mc².
