I think its definitely possible, but at what expense? If a group of scientists in the future, decide to travel into the past, that could dramatically change our world. You could be sitting at your kitchen table one afternoon having lunch with your kids, then all the sudden, POOF!! They are gone and you're homeless in Delaware! Makes me sick to think about it. :(
