So, Einstein believed time travel forward would not be possible.
I can only assume because tomorrow has not arrived for us yet.
Sounds a sensible & natural assumption.
But, if time travel ever becomes possible or on a more positive line, when time travel becomes possible, most thoughts will be to return in time, for what ever reason. Be it to witness, change, or merely to relive a moment in your own history. Then, one would go back, return to a time which in all tense and purposes for everyone else would be their `present` their `now`, from our `future`. Which we are assuming does not exist, because tomorrow has not arrived for us yet. So to me the answer is simple, if time travel ever became possible then surly time travel back & forward would have to be possible. If not no-one could return from a trip.
