...and that we know exist suddenly cease to exist? What would become of our memories of them, the knowledge of them, would that abruptly be wiped out? For example, if we are someday able to travel back in time and stop Hitler from exterminating thousands of people. If suddenly he did not have a hand in killing them and they lived, how would that change the time we are living in now? If we travelled back in time today and changed history, would my knowledge change? What about the history written in books? Would it be instantaneous? Would it leave a memory residue? For instance, if before we changed history, I travelled to a certain place, say Paris, regularly would I have that familiar deja vu feeling if I travelled there after we changed history, yet had never been there before within my new life? Could the human mind withstand a significant change in history? Will time travel ever be possible? And if it does, who will decide what we can and can not do with this ability?
