This whole anti-matter travels backward in time is a little confusing to me. After all, can't you hold anti-matter? If we are holding a container of anti-matter, and of course we are traveling forward in time, wouldn't the anti-matter disappear into the past? If not how can you say anti-matter travels backward in time?
My perception of time is an infinite amount of "NOWs". The reason we 'seem' to be going forward in time is because we are remembering what happened first. We remember events in order. I'm not sure if I'm being clear here or not. It's real hard to word.
Perhaps you are talking about some other type of time?
