Instead of travelling up and down, the light beam travels in the track drew in red color above. Howe

Now that you have the basic concept of Time Dilation, let's go a little deeper. airline ticket consolidators china In this post, I am going to introduce the time dilation to you in Mathematics. The time dilation formula is closely related to the Pythagorean Theorem. Without the Pyth Thm, Einstein would not be able to give us the amazing formula of time dilation.
A light beam is emitted from A to A', then back to B . Remember the light beam is travelling 90 degrees upward, A and B are basically the same point. The total time needed for the light beam to travel from A to B is given by:
Instead of travelling up and down, the light beam travels in the track drew in red color above. However, to an observer moving along with the device, the light beam travels the same path as the beam traveled on frame A. The new distance traveled by the light beam is L. As the path was longer, the light beam will need a longer time to travel from A to B. The time needed is given by:
This is the beautiful formula of Time Dilation. Perhaps you might notice airline ticket consolidators china that if we sub v=c (The device travels at the speed of light) , we will get: Humm, a division by zero error , not too good isn't?
