Back to the Future, Doctor Who, Star Gate, Bill and Ted’s Excellent Adventure, Terminator, The Time Machine, and so on so forth. These movies and TV shows have one thing and common witch as your can guess is time travel. But if you look at each single one separate not one time travel is the same from the other. Before we begin we shall learn what time travel is. Time travel is when one person, matter, or object moves in a three dimensional direction in time. The three dimensions are length, width and height but for this explanation we can also put it as forward and backward, left and right, and up and down. If we add the fourth dimension which Albert Einstein’s Theory of Relativity (Guidry) has shown to be time to these three dimensions than we have time travel. Now that we know what time travel is I can now tell you about the different types of time travel and if each one of these types will work. These types of time travel are speed of light, wormhole, black hole, time machine, cryogenics, and my own theory speed travel. To travel at the speed of light you will need to travel at the speed of 186,000 miles per hour or also called max speed limit in space in which “light always travels the speed limit through empty space.” (Space) ”It would take six years at full power just to reach these speeds.” (Hawkins) “Once spaceships approached the speed of light, their crew would start skipping through Earth years on a daily basis.” (Writers) But as Dr. Space says we don’t need to travel at the speed of light to get time travel as he uses “99.5% of the speed of light” for his explanation. And we don’t have to travel at the speed of light to move forward in time. We can be just like Cosmonaut Sergei Krikalev who was in space orbiting the ... ... middle of paper ... ...Paradoxes & Possibilities." Space.com. N.p., 21 June 2013. Web. 2 Mar. 2014. .

...eality. Our knowledge will only allow us to go so far, but we have accomplished so much in the discovery of time and space. Technology will soon advance as to where these theories could be proven and physically be possible.
At a glance, the concept of time travel seems absurd. Yet given some thought, you realise the metaphorical wall between the past, present, and future is smaller than you think. Light travels at a constant velocity of about 300,000 km/s. It is common knowledge that nothing can travel faster than that speed (as I will prove later on) and therefore because your eyes are sensitive to visible light – everything you see is a light wave in some form. Because of this finite velocity of light, if we observe a star, say Alpha Centauri 4 – which is 4 light years away – we do not see it as it looks today, but as it looked 4 years ago! If you look at the Andromeda Galaxy – 2 million light years away – you see it as it appeared 2 million years ago. Just as when you look at yourself in a mirror – 1.5 metres away – the image you see of yourself is not you now, but you 10 nanoseconds ago (0.00000001s)2. In other words, you look into the past every moment of your life.
If you have ever read Einstein's Dreams, you can appreciate my dilemma. If you have not yet had the opportunity to experience this wonderful novel by Alan Lightman, I guarantee that after you read it you will expand your perception of the nature of time and of human activity. The novel is enchanting. It is a fictional account of what one of the greatest scientific minds dreams as he begins to uncover his theory of relativity.

We have done a lot of research about space and have learned a lot with the technology we have. One of the main mysteries that we have not understood much is “the hole”. When I say “the hole” I mean the three main ones the black hole, white hole, and the wormhole. Each one is important in their own way, but this paper will be focused on black holes. I will briefly touch on theories that involve time travel, white holes, and wormholes.
Since the beginning of time itself, man has been dreaming of time travel. The current model of physics shows no obvious doubts towards the possibility of time travel, which leaves many questions (“Quantum Time Travel”). If the quarrel for time travel holds any truth, how will man manifest the means of going about it? Before the theories set forth by the men and women in the scientific community can be understood, one must have at least a general knowledge of the basics behind quantum mechanics, as well as the estimable; Einstein’s, theory of space-time. Also, in a world where time travel occurs, there is the possibility of a paradox, or impossible situation caused by the travelers’ actions. Many answers to the paradoxes have been set forth by notable people. Possibly the most widely accepted theory of time travel, Einstein’s black hole theory, still holds prevalence to this day. Some other theories have come to light recently, and most are yet to be disproved.

What is time? Is time travel possible? When nothing is changing does time still exits ? Is that really true? Are you real? Metaphysics is a branch of philosophy that is significant to us when questions and other clams bring curiosity about whether things are real or not.

Herbert George (H.G.) Wells’ 1895 scientific romance novella, The Time Machine, is considered to be one of the forerunners of the science fiction genre. Whilst the story was not the first to explore the concept of time travel, it is quite significant for its pseudoscientific account of how time travel could perhaps occur, this interpretation has shown to be quite influential to numerous productions in both media and literature. Wells explores a number of themes throughout this novella, however there are three prominent ones, the relativity of time, social Darwinism and evolution, and capitalism. These themes explore concepts which are relevant to society and creates connections with the intended 19th century audience.
Time Travel has always struck close to the imagination of the minds. From H.G. Wells ' "The Time Machine" to blockbuster films like "Back to the Future" - for years, time travel was the stuff of science fiction and crazy-eyed mad men but as physicists approach the subject of time travel with new advances in scientific theories and equipment, the possibility of time travel has become a more legitimate field for scientific endeavours. This paper will argue the possibility of time travel and the positive effects that this discovery will bring forth to modern day society: technological advancements.

...from the future has given us the secrets to do so? Is it because the future has not been acted out yet? Or has it been, and we are simply the past, seeing it as the present? Time travel has been a long debated subject. One such debate is, can it even be done? Many models of the big bang suggest that it can, while the theory of relativity says that it cannot be done.
Others have noted that we're all travelling forward in time (in fact, the theory relativity says that we are all travelling at the speed of light through spacetime) so I'll tackle the travelling-backward-in-time part of the question. And that breaks down into issues of whether backwards time travel is a theoretical possibility, and whether it's a practical one.
