Would you die if you traveled at the speed of light?

According to the theory of relativity, as an object with mass approaches the speed of light, its mass would increase infinitely and require an infinite amount of energy to continue accelerating. Therefore, it is currently believed that it is impossible for an object with mass to reach the speed of light. If it were somehow possible, the consequences are not fully understood, but it is likely that the extreme forces and energy involved would have fatal effects on a human body.
