Solution

The speed of light is 3 x 108 m/s.

If an object travels at the speed of light, its mass will increase exponentially. Consider that the speed of light is 300,000 kilometers per second and when an object moves at this speed, its mass will become infinite. Therefore, infinite energy will be required to move the object, which is impractical.

That’s the reason why no object can move at a speed or faster than the speed of light.
