The past is over and the future hasn’t happened yet; there is only the present.
Every record has been destroyed or falsified, every book rewritten, every picture has been repainted, every statue and street building has been renamed, every date has been altered. And the process is continuing day by day and minute by minute. History has stopped. Nothing exists except an endless present in which the Party is always right.”
― George Orwell, 1984
In reality we live in the multiverse. Multiple timelines exist and if you were to travel back along a timeline and change the future as you knew it you would be creating a new and different timeline.
That’s what I think. There’s no such thing as time like there’s gravity or energy. Humans think of time because they observe birth and death, sunrise and sunset, etc. but in reality time is just a concept.
Yup, I've been saying for some time (ha) that time is a human construct.
