The past can affect the future, and the present can affect the future. I have heard this already, but can the future affect the past, and if so, how?

you cant change what's in the past. Its history and already been completed. To change the past you would have to be in or from the future and go back in time to the past. Making the past the present and then you could alter the present wich would inevitably alter the future.

Well, meaningfully you can only say that the past has influenced the present and the present will influence the future. There is no mechanism for the future to influence the past. There is, in reality, only the present. The past is dead. The future may not happen.

Yes. Each and every event extends in the space by the speed of light. All material is a wave of the space so there is the possibility to reflect it. If you encircle an area in the space with a mirror which reflects the gravity waves it is possible to reverse the events which is equal to turn back time. Of course the time will be turned back only inside this "bubble". Such a mirror is not yet available -as far as I know- but extremly deflected space near a black hole makes the same effect.

yes
if in the future someone or something is able to eliminate a certain record in the past that event doesnt exist anymore
thus changing the past
like if someone was able to brainwash everyone to think that
George Wasington was never a president John Adams would be the first president
