Light? I mean they're light sails, right? 😆
(I'll see myself out)
Is lobster sauce made out of lobsters, or is it made of something else and you put it on lobsters?
It's made by lobsters. It doesn't matter what they make it of, or where it goes.
actual LOL from me
Oh man you’ve beat me to it
The best material would be something thin and shiny like mylar, no?
What do Space Pirates use? Let's use that.
Pixels, I think.
I would guess that the solution is in the name. Why else would they be light sails if they weren't made of light? Who's running this program?
Light.
Interesting problem. Kinetic energy is E~k~ = kv^2^, where k = 1/2 for Newtonian physics. To double your speed, you need to apply four times the energy. Momentum is p = mv, so doubling your speed doubles your momentum. When you're in a vehicle collision, it's your momentum that hurts you as you collide with the car frame around you. Small particles don't have much mass, but at relativistic speeds they have a lot of momentum.
Gigantic lenses to burn away bad people.
