Cosmic Time Travel essays

Cosmic Time Travel essays The book Cosmic Time Travel, by Barry Parker, is about finding out if time travel is possible or not. Is time traveling possible? Time traveling is possible and is proved by many scientists, such as Albert Einstein, Roy Kerr, Nathan Rosen, Schwarzschild and Stephen Hawking. The question is how? To Travel time, you will need to travel through a wormhole in space. The wormhole is not visible, but astronomers can point it out in space. A wormhole is an empty space, surrounded by galaxies (See picture below). Earlier on, the scientists discovered that passing through a wormhole is impossible. If a spaceship attempts to travel through this wormhole, it would pinch off, crushing the ship and the crew. In addition, severe stretching forces will be encountered as you enter the wormhole. They would pull you apart; in fact you would be stretched into a piece of string. And finally, if you did somehow manage to survive after getting into this wormhole, you would encounter high radiation levels. They would be so high that you would be literally fried. The problems were so severe that scientists soon abandoned the idea. As far as they were concerned, time travel was impossible. This was a great disappointment to science fiction writers and many scientists. For many years it seemed that time travel was beyond the reach of mankind. No one knew the way around the difficulties. Then, in the late 1980s, an important breakthrough was made. Scientists discovered that wormholes could be made traversal . The instability, or pinching off, could be prevented by applying a special balm to the sides of the wormhole. But this is no ordinary balm; nothing like this was known on Earth. It was so strange, and different, that scientists referred to it as exotic matter. When this exotic matter is applied to the wormhole, it can not pinch off. Furthermore, it was soon found that the stretching forces would be minimal, but unfortu...
