Is Time Travel Possible?
We’re all familiar with the idea of traveling across geography, but what about time?
Theoretical Physicist Michio Kaku presents his case in the above video clip. He also writes more about the idea in an article “The Physics Of Time Travel”
“Not surprisingly, time travel has always been considered impossible. After all, Newton believed that time was like an arrow; once fired, it soared in a straight, undeviating line. One second on the earth was one second on Mars. Clocks scattered throughout the universe beat at the same rate.
Einstein gave us a much more radical picture.
According to Einstein, time was more like a river, which meandered around stars and galaxies, speeding up and slowing down as it passed around massive bodies. One second on the earth was Not one second on Mars. Clocks scattered throughout the universe beat to their own distant drummer.”
