Why can nothing travel faster than light?

Is it because when you accelerate anything you give it mass and so it cant go faster or is it because everything has a mass in the first place so it cant go faster as light has a mass of nothing?

thanks for your help.

anything else couldnt see where they were going.

Reasons for this odd behaviour when velocity approaches speed of light.

Mass increases and reaches infinity.
Time stops for the moving object.
its volume becomes zero.
Infinite work is done.

Yes Ur argument is right that it b'coms difficult to accelerate a body.to velocity of light. Yeah light has 0 rest mass, so it can travel at this speed.

If a material object travelled that fast, the stress would tear it apart. Furthermore, it would have infinite mass (don't fully understand that one)
