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. Wells, Issac Asimov, Ray Bradbury, Robert Heinlein and Madeline L’Engle. There are songs about time travel, from George Harrison’s “Any Road” to “The Timewarp” from the Rocky Horror Picture Show. Time travel is also a prominent theme in commercials and advertisements, television shows, and art. In these media forms, time travel can be construed as good or bad. In some cases, the hero or heroine in the story travels back in time to save someone or change a bad outcome. In others, tampering with the past leads to tragedy in the future. A frequent topic on this is what happens if one were to meet himself in the past. Because we have no definite answers on the concept of time travel, the possibilities in entertainment are endless.
Scientifically, there are currently three popular theories on how time travel may be possible: through the use of black holes, wormholes, and cosmic strings. There are two types of black holes. Schwarzschild black holes are the more well-known and consist of a singularity at the center that crushes all matter beyond recognition. Kerr holes are rotating black holes where the singularity is formed in a ring, much like th...

...htly older while his twin has long since died of old age. The consequences of time travel on society would be tremendous. Today’s moral systems are based on the concept that (as Shakespeare wrote) “what’s done cannot be undone.” A society in which the correction of past mistakes or the prevention of future ones was possible would most likely have a radically different moral system less focused on the consequences of one’s actions.

In “The Cold Equations”, a short story by Tom Godwin, Godwin did some interesting things with time as he described the unfortunate story of a girl who stowed away illegally on a small spacecraft. The girl, Marilyn, did not know the consequence would be her own death. Unquestionably, in “The Cold Equations,” Tom Godwin manipulated time in order to influence the pace of the plot, because the manipulation and presence of time and deadlines creates suspense, inspires increased interest, and purposefully instills a sense of impending doom.
The Time Machine by H. G. Wells was an intriguing and exciting book about a Time Traveller and his journey’s through time. In this book, the Traveller explained to a group of men who were discussing the nature of time that time was the fourth dimension; just like the three dimensions of space: length, width and height. The Traveller argued that since time was a dimension, then it stood to reason that people should be able to move along the time continuum, into the past or the future. Most of the men do not seem to believe the Traveller or his theory, but agreed that they would like to travel in time, and talked about what they would do if they could. To illustrate his point, the Time Traveller went and got a model of his time machine from his laboratory to demonstrate and later returned to detail the places, things and people he had seen in his travels with his working Time Machine. Throughout the story, the Time Traveller faced setbacks and challenges, but the book outlined how he persevered and pointed to the future mankind faced.
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.
Previously, neuro-imaging studies have only observed the amygdala’s response to emotional face stimuli of the same cultural environment. This study went further and tested the amygdala’s response to participants of different cultures. In the study there were 22 adult participants: 12 native Japanese living in Japan (6 men and 6 women) and 10 Caucasians living in the United States (5 men and 5 women). The stimuli used to arouse the amygdala’s reactivity were 80 digitized grayscale pictures of faces that had different expressions. The facial expressions were of the four: neutral, happy, angry, and fearful. The photos were of 20 Japanese and 20 Caucasian men and women taken from the two groups. Participants were tested based on their own self-identified culture. The experimenters who conducted the studies used the participant’s native language. The independent variable in the study was the faces from the different cultures and the dependent variable was the amygdala’...
In “A Rose for Emily” Emily's father is overprotective and gives up on the idea of any man being good enough for his daughter, keeping her from finding true love and living her own life. It is a story of loneliness, feelings of being controlled, and depression. Until after her father's death, Emily, left with nothing but their home, that seems to symbolize the old south itself as it "had once been white, decorated with cupolas and spires and scrolled balconies.” Emily refuses to accept the fact of her father's passing. Soon enough, Emily meets Homer Barron, a man holding a temporary contract to work in the town. Several town members notice the time Emily and Homer spend together and assume they will marry with no hesitation. As time goes by, nobody has seen Ho...
The narrator and Emily both lived in houses with dominant male figures. The location of where they lived was different but they both faced seclusion in their own house. In “A Rose for Emily,” Emily’s house was described as “a big, squarish frame house ...
Censorship has been a big part of the world’s history and especially America’s history. One of the most quoted amendments to the United States constitution is the first amendment; “Congress shall make no law…abridging the freedom of speech, or of the press ...” This amendment guaranteeing free speech, press, and religion is still heavily debated and contested today. Censorship, as a challenge to free speech and press has been allowed many times and has been heavily debated itself. Many people censor for many different reasons and in many different forms. Censorship itself is not always a bad thing and has in some cases been used for protection of the general population.
Censorship is a controversial word that has been with us since who knows when. Ancient dictators would burn books because they didn't like them and force people to believe what they did. The question I ask myself, though, is if censorship in Libraries and schools is justified. My answer is yes, and that is what I will try to convince you.
Black holes are thought to be a portal to another dimension or a way for time to slip. Mainly all these theories follow the laws of physics and do not cross any illogical possibilities. For a way in which we can achieve any of these would be through many more years of research. If even physically possible for any of these hypotheses to coexist with one another. Learning that there’s a possible way for black holes to allow time to lapse or elapse. The study has been a challenge, finding ways in which these ideas could work. Theories about space time are not always true, but they allow us to have an improved understanding towards the, what ifs.
For years, the topic of censorship has a been highly controversial issue. Over the centuries, many people have fought and died to gain the freedom of speech and ideas. The impression that creative ideas and important information should be hidden from society and controlled by the government, is a discordant one. Censorship is the act of controlling the freedom of speech, ideas, and information. Unsuprisingly, people in the nineteenth or the twentieth century had no problem with the controversial issue of censorship. A century ago, technology just started to make itself known in the world. People had the radio, the television, and the typewriter. Although the internet was invented, it was hardly used as frequently as individuals, in modern times,
In old times, censorships’ definition was to suppress or restrict any kind of books, articles, journals, art, even speeches and any other forms of expression that were believed to go against religious, political, moral and social beliefs usually held by powerful leading groups, such as governments, businesses and churches. Our society has thankfully evolved since those times and censorship now is used not to prohibit, but to supervise and narrow specific contents that may not be necessary or appropriate to some groups or places, within the guidelines of our law. Censorship in a way is necessary mostly in our schools, not to control and restrict the learning environment, but to make the information and ideas delivered to children more focused on important material that will give them knowledge for their future and shape their personalities and opinions.
...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.
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.
For centuries, government nations and society have been withholding certain pieces of information from the public to ensure safety and prevent catastrophic out bursts; this detainment of public knowledge is called censoring. Censorship started in the early twentieth century, when profane literature began to surface in the wake of World War I; ever since then it's been a normal part of all society. Without the use of censorship and the methods used to sustain information, society would evolve and erupt into complete and utter chaos.
This essay aims to explore the necessities of censorship and the roles it plays in society. It will start by defining the term ‘censorship’ and an introduction to what is and has been censored through different periods of history. Finally, this essay will explore if there is a need for censorship in society with a focus on undesirable material and its effects on children and why.
