If we knew the future (not just hoped concerning it nor believed something about it), what would we do? What could we do?
I heard a fellow once reply that he would bet a million dollars on a particular football game. He was “absolutely” sure about the outcome of the game. Also, I have heard it said that you could make a million dollars over night if you knew for sure at what figure the Dow Jones would close tomorrow. One thing appears sure – humans would either directly or indirectly abuse others if they knew the details of what would happen in the future.
But, is it that simple? If we were to do anything at all due to our knowing the future, would we not actually be changing the future? Would that not show that we didn’t know the future after all? In other words, is it logically impossible to both know the future and do anything about it???!!!
Let me know if something is wrong with this reasoning?

I think this is the same concept as whether, if time travel were possible, we could change the past. Hypothetically, in ten years I decide to go back in time and, with my much higher technology and knowledge of history, I go back in time and assassinate Hitler before he is able to start WW II. Now, fast forward to the present again. In the “new” reality, HItler never existed. Since Hitler never existed, I have no need to go back in time to assassinate him. So, in ten years, with no need to go back and assassinate him, I do not do it. Since I did not do it, I never went back in the first place and thus he was never assassinated.
So, I have similarly wondered, if time travel were a reality, would it even be possible to alter history?
