I've been toying with the concept that perhaps we're already
time travelers and that it's so commonplace, that we don't even
notice it happening. Just look at our languages.* We have
fiction.* Could, Would, Should, Might, Did, Will, .. all things
not happening _now_. Even though our bodies seem to go forward,
our minds freely travel interdimensionally in everyday speech,
going forward, backwards, skipping around, investigating
alternative possibilities, coming up with universes that we
don't see.... *Why are we even able to do it at all?* That
amazes me.
