While watching a video where a high school student talked about the fourth dimension, I was struck by the idea of traveling so fast that you actually traveled in time. I then watched Stephen Hawking's Train Ride into the Future and found out more on the subject.
The universal " speed limit is 186,000 miles per second (the speed of light). In the video I watched, they explained the idea of moving fast to time travel by imagining a very fast train on a track around the world. The train would have to move so it went around the earth 7 times every second to be fast enough. Because of the laws of physics, the train could never reach the speed of light, but it could get close. The train would be protected form moving that fast. If a child were to run forward, the laws of nature would slow down time on the train to prevent their added speeds from moving at the speed of light. Time would pass slower on the train than it would on Earth. If the train left on January 5th, 2050 and came back on January 1st, 2150, the passengers on board would have only been there for a week. One week and they would have traveled 100 years into the future.This is amazing. If we could find the technology to build some train or ship that could move close to the speed of light, we could travel into the future. With technology, we could go wherever we want, even the future.
