This is what Happens If We Move in Light of Speed

1. contraction

This will happen to everyone. If we move near the speed of light, then someone sees us, will see us shrink. But from our side, everything we see will be seen moving toward the back we approach the speed of light, and also like to have smaller dimensions.

2. Slowing Time.

This phenomenon is called dilation (dilation), and again, it happens to everyone. It means that if we are moving near the speed of light, all the people who see us will see that the time will run slower for us: our watches run slower, slowing our age, our heart rate slows, and so on. But we also see the same thing, the age of the men slowed down, and so on.


But if we go at speeds approaching the speed of light and then we come back to earth at the speed of the earth, we will find the fact that during our journey, despite our age to run normally as usual, which happens on earth is the length of time that had elapsed.


3. More energy is needed to increase the speed.

Some of you who know a little physics know that the magnitude of the energy of a particle is E = mc2. Some of you also know that the kinetic energy = 1/2 mv2. But as you move near the speed of light, it takes longer and takes more energy to move faster. In the graph below, the purple line is the old formula for kinetic energy, but the red line is the actual energy (relativistic). Note that you will never really be able to reach the speed of light, but that energy was approaching infinite (infinity)

quote :
So that's what happens when an ordinary objects approaching the speed of light: visible contraction, time slows down, and the need for greater energy to increase the speed. Or for example, something that does not have mass (like photons, or mengkin gravity), must move at the speed of light.


quote :
Ok, if you use all the energy in the universe to your spaceship, you may be able to approach the speed of light. How close? The speed of light exactly 299,792,458 meters / second. And you can reach between approximately 1 x 10-30 meters / second of that figure - already really good. Put you reach that speed, what will happen?

quote:
First, the whole universe will contract transformed into just a few billion kilometers - less than one light year!

Second, time is slowed down so violently, until the age you will be only a few seconds while the universe in fact has increased the age of billions of years!

quote:
Galaxies will fuse, the stars will be born and explode in a blink of an eye. And finally, you will probably be the first to see the fate of the universe; if the universe had a late, you can slow down time so great for your own so maybe you do not just see it, you may do so in a matter of seconds.


So the problem is not only how to reach the speed of light,

but there are other reasons why mending we should not try to do it.
