Say this year you find out that your dad's best friend died in a fire in 1983. Soon, time travel is discovered. If you go to 1983 and save your dad's friend, wouldn't a paradox result? If you save him in 1983, the future you had no reason to go back to 1983 in the first place. Right? Plus, what would happen to everyone in the future who knew the guy died? Would he suddenly materialize? Doesn't time travel sound impossible because of these problems?
