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. The possibility of time travel has not been ruled out by scientists. If the human race truly wishes to advance through science, then time travel may be revealed. Today, it may seem like hocus pocus, but in the future taking vacations through time could be as much a reality as flying in a plane. But time travel raises interesting questions; what would happen if one were to travel back in time and kill somebody? Assume that somebody has successfully traveled back in time. What if this person met their grandfather years before he met the to-be grandmother and the time traveler decides to kill his grandfather? This creates an unending loop, or paradox, something that troubles many researchers of the topic. If a grandfather were to be killed, he would never meet his wife and... ... middle of paper ... ...edition.

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.
So, Rowling solved the problem to her satisfaction in stages. Firstly, she had Dumbledore and Hermione emphasise how dangerous it would be to be seen in the past, to remind the reader that there might be unforeseen and dangerous consequences as well as solutions in time travel. Secondly, she had Hermione give back the only Time-Turner ever to enter Hogwarts. Thirdly, she smashed all remaining Time-Turners during the battle in the Department of Mysteries, removing the possibility of reliving even short periods in the future.
The Time Machine is about a man who is a scientist and he wants to see

Time is the most elusive physical element. Despite familiarity with the concept, time is difficult to describe. Time is always the underlying assumption in our descriptions of the universe. In physics, it remains the largest barrier to the unification of relativity and quantum theory; some physicists believe time will have to be dismissed altogether if that unification is to occur (1). In more common experience, time appears to be an immutable and often lamented truth; who hasn't wished to "have more time," or to be able to "go back and do it over?"

...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.
Since most people have researched this, they’ve seen that many people believe that someone has come up with time-travel finally. Or, that maybe we live in an alternate reality/universe. No one has found any evidence of time-travel other than the “Misinformation Effect”, better known as the ”Mandela Effect”. There are a lot of sites, and blogs just about the Mandela Effect. The reason, most likely, is because when you learn about it, you get
What is time? We may be tempted to assume everyone has a notion of time that is the consistent with one another. A part of that “intuitive” notion of time contains the absoluteness of time – that time ticks at the same rate no matter what and it is independent. Even if an apocalypse were to happen to Earth, time will still flow nonchalantly. Yet, in the early 19th Century, Albert Einstein’s “On the Electrodynamics of Moving Bodies” or more affectionately known as the Special Relativity paper, confounded our common notions of time, as well as space. The theory could explain many weird phenomena like Stella Abberation , Fizeau’s experiment , Michelson-Morley’s Experiments . It also hypothesized mass-energy (which led to nuclear power plants) and predicted relativity of simultaneity , both of which has been proven at a later time. It has survived the requirements of the scientific method and was on the way to become one of the most famous scientific paper.
In this essay, I will discuss the possible logical contradictions time travel can create were it possible in every other sense. I will also discuss possible solutions to these contradictions in an attempt to retain that time travel is logically possible.

Wells’The Time Machine articulates what time travel is like through his writing and how he describes using imagery. The Time Traveller gives his audience an image of what time travel is and how to achieve it (Wells 6-7). This is a new thought for most of his audience to think about. The Time Traveler has optimism as he talks to himself about the risks of time travel (Wells 17). He has optimism because is not 100 percent sure if the time machine will actually work. The writer J. D. Beresford says this about The Time Machine: “We accept the machine as a literary device to give an air of probability to the essential thing, the experience; and forget the means in the effect.” The Time Traveler’s Time Machine has worked and has landed him in the year of 802,701. The Time Traveler encounters Morlocks in the year 802,701 and develops knowledge on what frightens them. The Time Traveler says, “I was roused by a soft hand touching my face. Starting up in the darkness I snatched at my matches and, hastily striking one, I saw three stooping white creatures similar to the one I had seen above ground in the ruin, hastily retreating before the light” (Wells 45). The Time Traveler demonstrates intelligence over irrationality and emotion. Instead of being frightened by the Morlock, The Time Traveller reacts quickly and now knows the Morlocks weakness, light. Later, when The Time Traveller quickly tries to flee when the Morlocks had trapped him in the room where his time machine was.
possibilities be? The ideas presented in this story are very entertaining and imaginative. From what I gathered while researching this novel and the time period in which it was written, the author, H.G. Wells, incorporated new ideas about science and physics into this story. It is not hard to see why this story is considered classic science fiction more than one hundred years after it was first published. This story is great because it sparks your imagination and persuades you to consider the mysteries of science and time travel.
We Like It, We Love It, We Want Some More of It: The Allure of Time Travel
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.
