Only if you cross the international date line. You travel either forward or back one day depending on direction of travel.
Technically everybody time travels. It's linear and only in a forward direction (you can never travel into the past). This is why clocks only go forwards.
Not at this time no. One day they will be able to time travel I think..but that's way far off from today.
Maybe.....in a universe of infinite probabilities, anything is possible.
You'd already have let yourself know, doncha think?
