Hi Gary
Feynman said that anti-matter is just time-reversed matter, so I thought that'd make a cool story about a time-traveller who receives a distorted signal from Base about some sort of explosion back on Earth. Normally timeships only launch and land in a vacuum (on the Moon) otherwise the timedrive, which short cuts through a parallel Godelian universe rotating rapidly in reverse time, mysteriously doesn't work. However because of the emergency he "returns", from the Future, to investigate and triggers the explosion as his time-flow reaches -1:1.
