In the original time travel novel, The Time Machine by H.G. Wells, the main character is sent on an extraordinary journey to the future. In this 800,000 year journey The Time Traveler, as he is known in the book, faces many new challenges and sees many new sights. Paralleling this fictional story, time travel is becoming a new focus of study. Time travel, a supported theory by many world-renowned physicists, is a widely debated topic in modern times. However, to fully understand this debate, a small lesson is needed. The intricacies of how time travel is theorized to work is not considered common knowledge. One of the easiest concepts to understand is paradoxes. This concept is described as an argument which the outcome does not seem possible with the initial proposition (Lycan 1). The paradox is one of the main bases for both sides of the argument. A seemingly harder concept, parallel universes, is defined as the theory that instead of a singular universe, multiple universes exist and everything is copied in each one of them (Wolf 101). This theory is opposed by the thought that only one universe exists. Following these narrow concepts, an overview of the Theory of General Relativity, a broad topic, is also needed to understand travel through time. This was proposed by Einstein and stated that matter being present will cause space-time to warp around it (Kenyon 1). This is followed by the Special Theory of Relativity which discuses how something viewing time around it, while moving, distinguishes how much time has passed between two events (Davies ). These are both integral theories that help both sides defend themselves. The hardest concept to master in studying time travel is closed time-like curves.

- Time Travel Essayexplanatory essayThe act of time travel assumes that we can travel time at a rate different when compared to the normal world. There are several theories on how one could travel through time physically even if the methods wouldn’t make a lot of sense logically. These methods range from altered movement in regular space to the abuse of certain cosmic phenomena which may or may not exist. In this paper I will argue that the physical possibility of time travel is sound and therefore possible even if only theoretically.
In this essay, the author
- Argues that the physical possibility of time travel is sound and therefore possible even if only theoretically.
- Explains that they will define time travel using a modification of david lewis' definition. the physical possibility will be encompassing the idea of general relativity.
- Explains relativity links gravity and acceleration with the passage of time and the force of gravity. the reference frame is defined as the things that are at rest relative to you.
- Explains the two ways in which time dilation can occur. the first is by accelerating away from a location that we will refer to as "at rest".
- Explains why the physics of time travel is sound, and how to simulate time dilation to take advantage of the phenomenon known as wormholes.
- Explains that by the laws of special relativity spacetime can be interpreted as a plane with curved regions at points in space with high gravity.
- Explains how to use a wormhole to time travel using the gravitational difference.
- Explains that time travel is meant to exist in a single consistent timeline, not using any many-worlds interpretation.
- Explains that time travel is physically possible in theory, given the laws of special relativity, and the wormhole method.
- Explains that time travel is backed by phenomena that have been proven to exist and whose behavior is predicted by the laws of special relativity.

It was a cold day in Los Angeles, my mom and I were cleaning the garage piling all of my dad's old stuff together. It would've been easier to deal with his death if he didn't passed away a year ago. No one knew about his death or anything that's why there was no news about it until now. I kept thinking to myself "man, I've only talked to him twice in my life and now he's gone forever. I wish I could just see him one more time." As i start to space out, my mom yelled "stop spacing out and help me with these boxes dude!" Panicking, "Ok, ok!" She lets out a huge sigh and pulls out a black suitcase, "Hm, I've never seen this suitcase before." It was a regular suitcase with a keypad on the side. "Can I keep this mom? It looks cool." I asked. "Help me clean up first dude." she said while throwing the suitcase to me. It was lighter than I thought, the suitcase felt empty like there weren't anything in there except for some papers. Little did I know that the object inside will change the way I look at history forever.

However, one thing remains true about timing is that we all are affected by it and cannot control it. Time does not work according to us; we have to work according to time. According to Einstein, timing and spacing are different features of the same thing and many other physicists have said that an object can move back and forth in space but nothing can move back in time.- Sito, T (2009).
In this essay, the author
- Explains that squash and stretch is the most important animation principle based on the understanding that only the stiff objects retain their shapes and objects that are not stiff tend to change their shape and size as they are in motion.
- Analyzes how the female and male characters in 'cloudy with a chance of meatballs' reflect the same emotion. the female character gives semi-realism whereas the male character exaggerates.
- Explains that even an inorganic object like a box, which does not have eyes, lips, and nose to show emotions, will only be able to convey its feelings through extreme exaggeration.
- Explains that exaggeration is a principle that is mixed with other animation principles, such as squash & stretch, posing and anticipation. the numerical values differ from one character to another, their movements and the requirement of the shot.
- Explains that people watching an animated scene will not understand the events on the screen unless there is a planned sequence of actions that leads them clearly from one activity to the next.
- Explains anticipation is the action performed prior to the primary action in order to communicate with the audience regarding what the character is going to to next.
- Analyzes how thomas and ollie johnston suggested that principles like these were developed through practical work and all of them are followed in real life.
- Explains that before the 'arc' animation principle came into existence, animators used the ‘rubber hose’ principle which was brought into line by the animation industry in the 1920s.
- Explains how the animation method came into existence with one of the longest running cartoons in the history, ‘felix the cat’, made by otto messmer and william charles nolan.
- Explains that unlike rubber hose, arcs are used for movements, especially limbs or any body part that has a joint to show realistic motion. any animation movement is observed from reality and copied, or at times modified.
- Explains that the characters' arms and legs look like a rubber hose. most action, whether by humans or animals, follows an invisible arc path.
- Explains that timing has always enthralled artists and scientists and they have come up with different theories, perspective, and conclusions about time and space.

- Explains that if an object passes into the ergosphere it can still be ejected from the black hole by gaining energy from its rotation.
- Explains that wormholes can exist within the classical black hole solutions of the einstein equations. they are useless for travel because they collapse before any spaceship could pass through them.
- Argues that although wormholes are merely science fiction, they could become a reality with advancing technology.

- Explains that time travel would allow for paradoxical situations, such as going back into the past and killing your grandfather before your father was born. khalili questions whether it would be possible to construct a wormhole and move it around.
- Analyzes how khalili uses the behavior of entangled particles to counter einstein's assertion that nothing travels faster than light.
- Analyzes how khalili shows that a truly advanced civilization might be able to make wormholes work by using something physicists call "exotic matter."

The fourth dimension is called space-time because the two elements cannot be separated: as I move in space, I also move forward in time. Spacetime as a unified dimension is a smooth constant. As 3D beings we only experience a “now” and Special Relativity says each person has their own relative time (CITE). If two people were observing the same event from two different locations, it would appear that the event happened at two different times. This is caused by the time it takes for light to travel through space to reach the observer. An example of this is two people standing half a mile away from one another and hearing the siren of an ambulance traveling on the road. The sound waves reach the observers at different times and fade away from their hearing at different times. The event being observed occurs at the same instant but is perceived relative to the observer.

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.
In this essay, the author
- Explains that the idea of time and black holes has been questioning scientists and many common people for decades.
- Explains that black holes are what's left after a star has collapsed and died of old age. the event horizon is most commonly simplified as, "the point of no return."
- Opines that if a black hole were ever possible, it could be something that would change our everyday lives. technology is becoming more groundbreaking by the minute.
- Explains that albert einstein and stephen hawking provided useful information about black holes, making black hole theories seem possible.
- Explains that a black hole slowly pulls an object, so the passing time would be hours, but the object passing through it would seem as if time was of minutes.
- Explains that the theory of general relativity provides a way to travel backwards in time. the possibilities are numbered but theories exist, in terms of 4-dimensions and semiclassical gravity.
- Explains that many people that contemplate black holes have brought up the arguable subject on a theory to obtain any possibility to pass through them.
- Explains that our current technology makes it impossible to survive the forces being exerted from a black hole.
- Opines that a black hole's gravitational force will be too powerful for anyone or anything, and it would be impossible to escape.
- Explains that time itself will make it physically impossible to travel backwards, since time is merely a thought.
- Explains that black holes have been contemplating people's minds for a long time. they provide proper knowledge and most of these theories comply with the laws of physics.
- Opines that the invisible firewall of the event horizon was a hypothetical theory that has yet to be proven.
- Opines that if a human isn't in the right mindset to handle what takes place within the black hole, we could always invent different concepts. technology is big factor in making these theories.
- Explains that black holes are collapsed stars that create forces that make getting near them dangerous. spaghettification and other forces could make it harder for us to find the materials in order to test these theories out.
- Explains that black holes are one of the biggest mysteries of space, people have learned a lot about them over the years.
- Opines that we can learn from the theories provided by many scientists and use them to our advantage in the near future. technology makes it easier to make these theories a greater possibility.
- Explains that science has taught us different ways at which new discoveries could be used to greatly impact our lives. these advances are what will allow more theories to be born and could possibly come to reality.

Firstly, Lewis highlights the that “time is one dimension of four”, in the fourth-dimensional world, suggesting that time is just as perceptible as any place and potentially where the time traveller will send the message. Second, fourth-dimensional spectrum also considers causation and possible reverse causation, that is there must be awareness for earlier events to be causally dependable on the future events, and therefore how communication will take place between two different times. Lewis argues that his grandfather paradox can provide solidarity with the past, only if a time traveller was to travel to the past, they would not be able to make any changes that may potentially lead to them never
In this essay, the author
- Argues that if the future is already determined, it must be possible to know in advance what will happen. if that is so, then free will is impossible.
- Argues that free will cannot be correlated with randomness and that all other possibilities are exhausted.
- Explains that they will explore the concept of free will by drawing a correlation to determinism and analyse if freewill is dictated for us. their argument will present several contradictions, but they are relevant to their conclusion.
- Argues that the future is the result of a pre-determined set of paths that cannot be reconstructed or changed by free will due to the events that occurred in the past.
- Analyzes how david lewis' "the paradoxes of time travel" differentiates temporal parts and the causal order of events by creating a form of connection between time.
- Analyzes how lewis argues that if time is made up of temporal parts that cannot be changed, tim could potentially change the future drastically, preventing his grandfather and, therefore, himself from being conceived.
- Compares the doctrine of fatalism and determinism, arguing that events occur due to cause and effect.
- Explains that a determinist would make no link between cause of events and the events that actually happen as they happen. to say something is rendered unavoidable by its causes is not logically sound.
- Analyzes how david lewis describes time as a plane made up of temporal parts.
- Explains that determinism is unavoidable, but free will is not defined as the ability to avoid future events.
