When traveling anywhere in our universe, time slows as an object reaches the speed of light, according to Einstein's theory of special relativity. This makes scientists believe that if we could somehow travel faster than the speed of light, that we can travel backward and forward in time. ... If you think about it, while traveling in a car, train, or plane, you reach speeds that get closer to the speed of light, which means that we have already actually traveled into the future, but in an incredibly small way. If you and a friend were to set your watches at exactly the same time, then ...

It was discovered, in 1676, by Danish astronomer, Ole Christenson, that light travels at a very high, but finite speed (Hawking, 18). ...

One of the first physical processes Newton would revisit at Cambridge was that concerning light. He theorized that even white light was composed of a variety of constituents, each of a different color . ... Hodges notes that this analysis allowed Newton to envision: "light and visibility of objects as a result of the rather mechanical movement of a host of miniscule particles or "corpuscles" of light through air, from object to observer, at the speed of about 168,000 miles per second". In more than one way Newton's theories of light interrelate with his theories of gravity. ... ...

There are many arguments for and against the existence of a God. Some have been eloquently thought out and backed, others not so much. We hear constant ramblings and lectures of how everything began, why it is, and how to act from all sorts of perspectives around the world.
