    Negative energy is almost certainly not a thing.

    If two objects made up of matter and antimatter collide, they would annihilate each other and release all of their energy as an explosion

    If two objects made of energy and anti-energy collided they would also annihilate each other… except there would be nothing afterwards. Total information loss as no energy would escape the impact, since there would be no more energy afterwards.

    Good ankle support, great traction, won’t come off. Will get you detention if you wear them for gym, though, even though the skater boys’ shoes fly off literally all the time, no, my shoes are the unathletic ones worthy of ridiculously draconian punishment.

    (what do you mean? It was twenty years ago. How could I still be salty about it?.. Me bringing it up is proof I am? How does that even make sense? I can’t just talk about relevant things when they come up?! What is this tyrannical reality we live in where we can’t even talk about relevant things?!!)






  • Speed isn’t the factor being multiplied here, it’s fuel efficiency. It would be much faster to give the probes enough delta-v to handle flying straight (via a parabola) to their ultimate destination than to bother wasting time with gravitational assists. But the cost in fuel would be astronomical. Literally, even.
