Time Travel

Time Travel…A Possibility?

From my previous paper on “What is Time?” I concluded that

time is broken down into past, present, and future. When looking at

each of these separately, they can be defined as:

Past: Gone by in time and no longer existing.

Present: The period of time now occurring; existing or occurring now.

Future: The time or a period of time following the moment of speaking

or writing; time regarded as still to come.

When taking the definitions of past, present and future into

consideration time travel is an impossibility, as there are rules needed

to travel time that break each and every definition.

If we were to travel backwards in time, we would be in the past.

But isn’t the past what ceased to exist? Traveling back in time would

be making the past our present, breaking its definition.

The future is defined as what is still to come. If we were to

travel forwards in time, our future would become our present. The

future is shaped by decisions made by people and events taking

place all over the world. If one or two people were to travel forwards

in time, it would be only them traveling forwards in time, meaning the

decisions that make up the future have not yet been made. Therefore

they would have to be traveling into a fiction of what is still to come,

not a reality.

When explained scientifically, time travel concentrates on

things such as quantum physics, Einstein’s theory of special relativity,

and the grandfather paradox.

Einstein’s theory of special relativity links between space and

time. It states that relative to a stationary observer, time passes

slower for faster moving bodies. This is called “Time Dilation”.

Therefore, in theory, time dilation can allow us to move forward in

time.

The grandfather paradox is a theory discussing the possible

effects of traveling back in time. It is called the grandfather paradox

as it discusses the consequences of going back in time and killing

your own grandfather. Would you cease to exist? There are many

problems that could arise from time travel, and the grandfather

paradox discusses how dangerous and deadly these problems could

be. If one was to have the power to travel back in time, he/she would

also have the power to change many of the events that have shaped

our present, making what was once a reality fiction.
