Pun intended, but still a serious question.

Would a neutron matter? (Pun also intended, but also serious)

How did you calculate that? The question didn't even mention a specific speed, just "near the speed of light".

The kinetic energy for a grain of sand near the speed of light is somewhere between "quite a lot" and "literally infinity" (which is, in a sense, the reason you can't actually reach light speed without a way to supply infinite energy).

Ke=1/2 M V^2 Not relativistic. So wildly low. But certainly a low bound. My point being that nuclear bomb grade energy is certainly in the ballpark.
