Probably even very small objects make high-speed flights impossible because of collisions.
- clarkmoody 13y agoI believe we know that it's not empty. Take the asteroid belt: there are millions of objects there, yet we fly through it with interplanetary probes, no problem. We know that space is not empty, but it's empty enough.
- Zimahl 13y agoI've heard our asteroid belt described like this: The odds of randomly happening on an asteroid while traveling though the asteroid belt is about the same as randomly happening on a ship in the Pacific Ocean.
