Time dilation is difficult to explain simply, and has different explanations
according to the setting. Best put, it is the slowing of time experienced by someone as they near
the speed of light.
Time dilation is difficult to explain simply, and has different explanations
according to the setting. Best put, it is the slowing of time experienced by someone as they near
the speed of light.
As your rate of speed gets closer to the speed of light (roughly 186,000 miles per second), the
conception of time actually speeds down. If one was to observe you
getting closer to the speed of light, it would
appear that your actions were slowing down.

Well, there are some things we must take into consideration. Since the
airplane was moving faster than the little geek on earth, time
actually slightly slowed down on the plane. “But why don’t I come out 50 years younger than what
I should be when I get off a plane after a trip?”

I should be when I get off a plane after a trip?”
Because the airplane isn’t moving nearly fast enough
for someone to actually sense the slowing of time. In
fact, you’d have to reach half the speed of light to
merely experience a slowdown of 15%! However, with the atomic clocks, we
are able to detect the extremely small difference
in time.

As you near the speed of light, time slows down. If you’re
going at 10% of the speed of light, time slows down a
mere .5%. Likewise, if you’re going at 50% of the speed of light, time slows down 15% (a 3000 percent increase). If you’re going at 90% of the speed of light, time slows
down nearly 60%! And going at 99% of the speed of light slows down time about 85%!

You probably noticed that the increase of the slowing of time is quadratic, rather
than a steady, linear increase. For example, look at the graph to the
left. Notice how the line at the beginning drops only
steadily, then takes a huge dive near the end (a
quadratic slope).

Because the “slope” of time dilation is quadratic, there are
two things that are certain:• The closer you are to the speed of light, the more time
slows down to a certain degree.
• With our current knowledge, time can not be totally frozen.

Why not? Because, like said, the graph is quadratic. This
means that while the faster you go and the closer you
obtain to freezing time, you can’t freeze time because you would have to be traveling at
the speed of light itself. According to modern theory, objects with a mass cannot
reach the speed of light.

Time dilation is actually a very big deal: it holds some of the
thousands of keys to unlocking time travel. A man could go on a super-fast ship for 50 years, and come back
only 1 year older, also feeling as if he was only on the ship for 1 earth year. Scientists are looking into how this works and how it
could be used to our advantage.

It is obviously not that simple. Before actually attempting this first-hand, scientists
would need to find a way for humans to travel close to
the speed of light, whether it be on a ship, or somehow
through a wave that is nearly as fast as light, such
as cosmic rays.

Albert Einstein (born 1879, died 1955) is credited
with the creation of the Theories of Relativity.
Within this theory, Einstein says that time
changes with motion, like how time changes from in
an airplane, to on the earth. Previous scientists thought similarly as well.

If scientists are actually able to find a way to get a human travel
close to the speed of light, we would be able to do several
things in the future. We would be able to preserve humans to
live longer than their counterparts on earth. When
they come back to earth, several years, decades, or even
centuries could have passed, and the human would be only a few years older than when they
left.

Time dilation could very well be the ultimate way for humans to “live longer”. It is one way to
unlock the secret of time travel, as well as get a more familiar
feeling of time. As humans continue to make advances in the field of time and science, we will continue to find out
more and more about time and its mysteries. Perhaps one day,
we’ll find a way to actually freeze time, or even go back in
time.
