Relativistic Phenomena !

When the speed of an object relative to other is very high, close to the speed of light (c = 300000 km/s), the world that would be seen by the object is weird and different from the everyday world. The phenomena that occur at high speeds (or energy) are called the relativistic phenomena. The Special Theory of Relativity deals with all these phenomena of the WORLD OF BIG !

The Special Relativistic phenomena include LENGTH CONTRACTION (sometimes also called the LORENTZ CONTRACTION), TIME DILATION, INCREASE OF MASS and so on, which are beyond our intuition.

Enjoy the following you tube videos of some of these phenomena.
