In their paper, the duo calculated that an electron beam traveling at these speeds could generate enough power to propel a 2,200 lb (1,000 kg) probe — about the same size as Voyager 1 — up to 10% of the speed of light. This would enable it to reach Alpha Centauri in just 40 years, a significant improvement over the current 70,000 years it would take.

At that speed, what would happen if the ship collided with something?

Yeah, that's a LOT of kinetic energy.

You need a deflector dish.
