Let a man named "A" be traveling in a train at a speed of 100 km per hour. He is comfortably sitting in the seat no.10 of the compartment "A1".
Let another man called "B" be standing in the open field where that train is passing through. Let us assume that the man B is having a "special instrument" using which he is able to follow the train and also able to watch what is happening in the compartment A1 in detail.
Let A toss a coin and B watches that event from outside the train. Now, put a question to A, "Where you tossed the coin and where it had fallen?" He will definitely answer like this " I have tossed the coin in this compartment A1 and it has fallen near my feet. It has not gone anywhere else. Why this question?"
Next, put the same question to B. He will answer "the coin has gone up at one place but it has fallen a few meters away from the point of throw". (Since the train is running very fast). Hence the event is different for two men. This is relativity.
Einstein says, when a man is traveling nearly at the speed of light, the things will be different.
1. The mass of the fast traveling object will increase. In a lab; when the electron approaches the speed of light, its mass is found to increase. .
2. The length of the traveling object contracts.
3. The moving clock ticks slowly. That is, for a traveling man the time will run slowly and he will age slowly.
The light speed can not be attained by men. So we do not experience the above set points. Even though Einstein's theory of relativity is mathematically proven and experimentally verified, we find it difficult to digest.
