No, a human could not survive light speed.
According to Einstein's Theory of Relativity, nothing with mass can actually reach the speed of light. Therefore, the question of whether a human could survive it is fundamentally meaningless. As the reference material states, it would take an infinite amount of energy to accelerate a human to the speed of light, making the scenario impossible.
In short:
- Theoretical Impossibility: The laws of physics, as we currently understand them, preclude travel at light speed for objects with mass.
- Infinite Energy Requirement: Reaching light speed requires infinite energy, an impossibility in our universe.
- Meaningless Question: Consequently, considering survival at light speed becomes a hypothetical exercise detached from reality.
