Given our current understanding of physics, it is nowhere near possible to make anything the size of a human being travel anywhere close to the speed of light.

The reason for this can be found in Einstein's famous E = mc^2 equation.  In this equation, E is energy, M is mass and C is the speed of light.

What this shows is that you would need a huge amount of energy to make something go at the speed of light.  You would need an amount of energy equal to the mass of the thing you are trying to move times the speed of light squared.

This means that you would need an almost infinite amount of energy -- much more than we are able to generate.
