Almost everybody knows the value of c that is 300,000 Km/sec. Means just impossible to even imagine.
On earth, it is not possible for something to achieve the speed of light. But if let us suppose an object moving with c then what’s about the object?
So, the strange thing is this that the object will disappear, but why?
The answer for its invisibility is cleared by the concept of LENGTH CONTRACTION. It provides us a relation between the rest length, its velocity and between speed of light.
By this concept, we get the approximate lenght of an object moving with speed of light as ZERO.
Hence, light is the biggest mystery even now. As, we didn’t get any visible object till now moving with c.
