Time travel
Is time travel possible, and will it be possible in the future? If you chose to travel through time, you could put together a spectacular itinerary. You could meet historical figures such as Buddha, Muhammad, or Moses. You could see what Cleopatra really looked like or attend Shakespeare's first production of Hamlet. You could participate in the last supper with Jesus. You could go and talk to Adam and Eve. The possibilities are unlimited.To first understand if time travel is possible there are a few theories that we must understand. The first will be Sir Isaac Newton's theory of gravity, and then we will look at Einstein's general theory of relativity. I will try and make this easy to understand without a lot of mathematical expressions. "In 1687 Sir Isaac Newton published a book called Philosophiae Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy). According to some researchers this was the single most important work in the physical sciences."(Hawking 4) Newton put forth how bodies move in space and time. He came up with a law of universal gravitation, which showed how each body in the universe was attracted towards every other body. Depending on the mass of the bodies and how clos

Something that is interesting is that we have no way of determining the rate at which time is passing. An astronaut that is traveling at or near the speed of light, would not notice that time had slowed down or stopped which is know as time dilation." (What is Time? 2) "This states that bodies moving at high velocities experience a time that ticks slower than the time measured at zero velocity."(Parsons 2) Everything would appear to be normal, until he returned home and compared his clock with others. Also the faster an object moves the more time is distorted. There is no definitive answer to the question what is time, but some scientists say we live in a four dimensional world. Three dimensions of space and one dimension of time. Some say that the future is already there just waiting for our conscious to pass over it. If time is real, like the other three dimensions are real, would indicate time does exist and is there waiting for our conscious to pass over it.
