Is Traveling at the Speed of Light Impossible?

[rojasharma]

use the equation m=mo/sqrt(1-v^2/c^2) to show that traveling at the speed of light or beyond is impossible.

use the equation m=mo/sqrt(1-v^2/c^2) to show that traveling at the speed of light or beyond is impossible.

1. what is the limit of that expression whene v--->c?

2. what is an immaginary mass?

mo is the mass of the object measured in the refrence frame in which it is at rest. m is the mass of the object as measured in a refrence frame moving with speed. in the equation v can never equal to c...it will...be less because of sqrt 1-v2/c2

yes bu why u cannot reach c? what kind of singularity u get? what does it mean physically?

It's best to think of the m in your equation as the total energy of the object relative to the rest frame (including the E=m0*c^2 energy). So what happens to total energy as v approaches c?

 

[rojasharma]

the energy approches infinity?

Yessss.
