Free will exists currently, it may not in the future, once everybody is on prozac, free will will be abolished. Time travel is impossible, as is traveling through a worm hole unscathed, everything is ripped apart at the atomic level when traveling through a worm hole. It is a window to another universe but I would not recommend going through it any more than a regular window. The only way to make a successful trip to another planet is to have “star drive” i.e. a fusion engine. We had better take care of the one planet we have as I don’t think we will have any other planet to colonize in the near future.
