This article explains the concept of the “twin paradox”, which is also known as “time dilation.” Craig starts his article by introducing the readers to Albert Einstein’s concepts of relativity. According to Craig, Einstein believed that “the basic premise of relativity is that neither time nor space is absolute.” Craig then goes on to explain the background of time dilation, and tries to explain the complicated mathematics behind time dilation. To explain the concept of “twin paradox”, Craig creates a fictional story of two twins, Dr. Mills and Dave Arnold, who decide that the oldest of the twins should travel at the speed of light to a distant planet while the other twin stays behind. The paradox lies in the question of which twin would age faster, Dr. Mills or Dave Arnold. Craig concludes that due the theory of relativity and the analysis of accelerated time frames, Dr. Mills will age faster than Dave. Craig acknowledges the fact that most people who are new to relativity would make the wrong connection between differential aging and acceleration. He concludes his article by stating that “time is as ambiguous as social interaction” and that it is possible to increase youth by time travel.
What I found most interesting about this article was Craig’s idea that it was possible to increase youth by traveling at the speed of light. If this was discovered by our society today, there would no longer be a need for makeup—everyone could simply travel through time in order to look younger. This article gave me greater insight about both time travel and about time dilation. The article’s ideas seemed far-fetched at first, but after rereading...

... obstacle that most people who wish to travel in time must face—the universe can only hold a certain amount of matter in order to remain stable. The article then discusses some theories of time travel, which involves the understanding of quantum mechanics and quantum realities. The article then breaks the idea of time travel into 4 sub-theories: fate, alternate universe, success, and the observer effect. Of all the theories, I was most interested in the “observer effect” theory. The “observer effect” theory stipulates that anyone who travels into the past runs the risk of altering any important events of history. It is possible to kill a relative if traveling into the past. This article helped answer many of my questions about time travel, but I wished it would have provided the readers with more theories to help extend its belief that time travel is possible.

- When a star "dies" it can do many different things. It can form a neutron star, expand to a red giant and shrink into a white dwarf, or sometimes collapse upon itself to form a black hole. This is mostly dependent on the density of the star. When massive stars, those twenty times the mass of our Sun or more die, they must either exhaust all of their excess mass or implode upon themselves and form black holes. Gravity overwhelms even the nuclear forces. The gravitational force becomes so strong that nothing can escape it, even photons of light, hence the name "black" hole....

- 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....

- 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.... [tags: Time Travel, Speed of Light, Films]

- 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. First, we must determine what is meant by time and time travel. Time travelling, defined by David Lewis is as follows “Any traveler departs and arrives at his destination; the time elapsed from departure to arrival is the duration of the journey....

- What are Black Holes. A black hole is theorized to be a collection of collapsed matter of whose gravitational pull is so strong that not even light can escape its force. The matter is is forced in a very, very tiny area and therefore the matter is very dense. Since light cannot escape, they are considered to be truly black. This, obviously, makes it hard to detect an actual black hole, and therefore, have only been theorizd to exist. These theories are slowly turning into "conclusive evidence." This evidence includes the particle dust given off from matter entering the black hole, as well as observations of orbits of bodies near the black hole.... [tags: physics science space]

- 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. Wells, introduced the idea in his 1895 novel, The Time Machine. Since the novels release, writers and movie producers have drawn from Well’s imaginative ideas and expanded it to unexpected hype. Time travel has evolved over time from a dream into something that many believe is possible. The hundreds of successful movies and novels using time travel have caused me to ask the question, what is it about time travel that is so appealing.... [tags: Time travel, Time, H. G.

- The possibility of time travel has been explored extensively in the science fiction genre of literature, movies, and television shows. Time travel has an assortment of theories, with views on the definition of time travel, the metaphysics of time, causation, and arguments against the possibility of time travel with responses to counter them. Definition of Time Travel Time travel does not have one standard definition. A popular definition of time travel is by David Lewis, where the time elapsed for the time traveller to get to a destination is different from the time between the departure and arrival time....

- Is Time Travel Possible. Time travel has always fascinated humans. The idea of being able to change the past or the future creates infinite possibilities. The most common form of time travel is through the use of a time machine, although in some cases, characters with mystical powers can transport others in time. The subject of time travel has been brought up in various blockbuster movies, such as Back to the Future series, the Terminator trilogy, and even Bill and Ted’s Excellent Adventure.4 In the literary world, some well-known writers have written about time travel, including H.G....

- Concepts of Time Travel Some people live their lives focused on the present. Then there are those who constantly look ahead, striving to achieve greater things in the future. Regardless of how you look at life, one thing is the same for all of us: time. Time is a train that keeps on chugging no matter what; we are all on this moving train whether we like it or not. What if it was somehow possible to get off the train and board a slower train where time moved slower. Since the train represents time, you age slower on the second train.... [tags: Papers]

- 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]
