Twin Paradox

Dilation Time or the language of Time Dilation, this concept is based on Albert Einstein's special theory of relativity which explains that time is relative based on reference observations, and the only constant velocity of observation is the speed of light.

In the illustration, einstein mentions if there are twins, say named Elang and Iqbal, continue to suppose the Eagle travels into space with a spacecraft that is fast (space shuttle) which is almost close to the speed of light and back to earth after a few hours outside and back to Earth, when they meet again, time on earth has been running for years so that the age of the Iqbal who lives on earth is much older than the Eagle. This is called Twin Paradox.
