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 did travel to the past, we would end up in a different universe that is a replica of this one. One of the most basic concepts is that of Dilation, a stretching of something. Some scientists believe that the main gateway to the past or future is a wormhole. Einstein’s general relativity theory explains about universal constants, this is important to understand the concepts of travel at light speed. Traveling to the past could create problems if someone tried to change something. This is a paradox. A few of these paradoxes are explained through the use of quantum mechanics. Sailing though the cosmos at the speed of light with no time passing us by, moving throughout time to witness the ancient Egyptians create their masterpieces. This is an exciting concept that we could actually formulate and make happen.
Before the time of Einstein, Newton and other great investigators thought of space as an infinite expanse in which all things exist (Hewitt 213). We are in space and we live in it along with all of the planets and stars. It was never clear if the universe exists in space or space exists in the universe. Dose space exists outside the universe or only within the bounds of it. The similar question, does the universe exist only in time or does time only exist in the universe? Was there time before the universe, and will there be time after it ceases to exist? “Einstein’s answer to this is that time and space only exist within the universe. There is no time or space ‘outside.’(Hewitt 213)” Einstein said that space and time are two separate parts of a whole called space-time (Hewitt 213). To understand this, consider our presen...

... all his work. His younger self could reproduce the paintings and profoundly and irrevocably affecting the future of art. This would involve no creative energy by the “inventor.” The reproductions would exist because they are copies from the original and the originals exist because they are copies of the reproductions. No creative energy would ever have to be put forth to create these masterpieces. Because of the chronology principal time travel, by some, has been ruled out.
The cosmos await us, and the history of our world is at our fingertips. Would we use this great power for good, bad, and wealth? All we have to do is get in our spaceship, set sail for the nearest wormhole, and hope for a little luck, and we can witness things only told in stories. Only the traveler can decided what he or she wishes to go back for. The theories today state that traveling through time is possible, however they do not say what could be the repercussions of our actions. This great frontier awaits us; we have the knowledge, and are slowly but surly developing the technology. Only time will tell when time itself no longer rules our lives as one of the chief amendments of the universal constitution.

Essay on The Time Of Time Travel

- We Like It, We Love It, We Want Some More of It: The Allure of Time Travel Time travel has been a growing theme in literature and film since the Father of Science Fiction, H.G.

Time Travel Essay

- Time travel is feat thought by most to be impossible. After all time travel is what many science fiction movies are made of. Let us not forget such movies as “Back to the Future” or “The Time Machine.” Yet unlike those movies time travel is not necessarily fiction. “We are in our own time machines, our hearts are pumping blood, we're breathing, we are existing through time (at least until our own personal time machines seriously malfunction).” (Need help citing this!) Still surrounding this topic is a series of theories, and surrounding these series is a number of flaws....   [tags: essays research papers fc]

Time Travel Essays

- Time Travel First of all, to give you a better concept of time I will use a personal theory of mine. When you look up at the sky at night, at the stars, what are you seeing. Do you think that collage of stars actually exists. Most of them do not. When you look at the sky at night you are seeing the past because it takes an obscene amount of time for the light from those stars to reach earth, and in that time those stars may have disappeared. It works both ways. When an inhabitant, if there is one, on a planet around the star that you are looking at looks at our sun he is also seeing the past....   [tags: Physics]

Exploring Time Travel Essay

- An essential requirement for the possibility of time travel is the presumption that future and past were somehow real. But according to one popular view only the present is real, and to suppose that the past or future are also real is to suppose that the past and the future are also present -- a contradiction. According to this sort of Heraclitean metaphysical conception, the future is genuinely open: there is no realm of determinate future fact, no denizens of the future to identify or talk about, though of course -- in the fullness of time -- there will be....   [tags: Reverse Causation ]
