For many years time travel was the stuff of science fiction. This was all just part of the world's imagination until recently. Scientists now believe that the current laws of physics allow us to travel though time. They believe that we can now travel back to see our founding fathers sign the declaration of independence. We could travel to 2999 to witness the birth of the next new millennium. Such travel would require a machine capable of withstanding great pressures and incredible amounts of speed. The act of actually traveling though time is for the most part, agreed upon, but the implications of such travel is not so decided upon. Many different theorists have different views of what could happen and some go, as far as to say that if we…show more content…
Time for a stationary observer on earth and for an astronaut on a spaceship of high velocity is different. A person's heart beats to the rhythm of the realm it is in. One realm of time seems the same as any other to the person in the realms, but not to an observer outside that realm that can see the difference. As an example, astronauts traveling at 99% the speed of light could make a trip to the star Procyon that is 11.4 light-years away in 23 earth years round trip (Hewitt 229). Because of time dilation, it would seem that only 3 years passed for the astronauts, there clocks would be 3 years older; they would be biologically only 3 years older (Hewitt 229). It would be the mission control people that would appear to be 23 years older. The question is why dose this happen. Let's say that we are in our hometown, looking at the grandfather clock that is in the center of town. The clock reads 12:00 noon. Light from the sun bounces off the face of the clock and hits our eyes. We then turn our head and the light misses us and travels off into space. In space, there is a space ship that is traveling at the speed of light. An astronaut looks out his passenger-side window and sees the reflection of the clock. It reads 12:00 noon. As he continues to move at the speed of light, he keeps up with the reflected face of the clock. In the space ship time would pass as normal, but time in the universe would have seemed to stop. This might sound like
