SPECIAL THEORY OF RELATIVITY-4
Time can also increase and decrease its relative velocity.It mean time blow with the different velocity at the different place.E=ENERGY
M=MASS
C= SPEED OF LIGHT
This relation between ENERGY AND MASS is valid only if and only if time is relative .If time not relative then this equation would be valid unless human being not get the speed of light
But how let discuss this with the help of example
Suppose in future we have a space craft which can travel in space with the speed of light
A astronaut are travelling in this space craft
suddenly he feels for walk and he start walking inside the craft now what is the relative speed of astronaut -- RELATIVE SPEED OF ASTRONAUT=SPEED OF SPACE CRAFT➕WALKING SPEED OF ASTRONAUT
clear we can understand the relative speed of astronaut is greater than speed of light
E=MC^2 is valid only if speed of light is greatest speed in whole universe .Suppose we would get the speed of light in future then by Theory of Relativity of motion we can get a speed which is greater than to speed of light.
