They say time is more about position and speed, hence, space-time. Now I’m no scientist, but please hear me out on this.
Let’s start simple. Let’s say you had a favourite mug, and it was lost or broken. Instead of mending it, let’s say you recreate it perfectly, right down to the smallest subatomic level. Isn’t this a form of time travel? The proper way? What would be the difference between the two mugs if they are EXACTLY the same? Only their position from where they’re placed, right?
Isn’t the same true for people? If a person was duplicated, (not a clone), but perfectly duplicated; you’re sitting at the same breakfast table with them, isn’t this a form of time travel, the only thing making them different is that they’re not sitting in the same chair than you. What will make them different in time is if they start living separate lives.
So Let’s take it a step further. If you could duplicate a solar system at a time where the second world war was still raging; I mean the planets, people, everything is exactly the same … would they make the same choices. When you are there wouldn’t bestriding this planet, automatically put you in the past? Or would the whole solar system be different, because the rest of space is different?
Trying not to talk about parallel universes, but then what is a parallel universe other than something which is spatially different from our universe?
Thus, the question is: isn’t it more practical to manipulate space, through, example duplication, than trying to travel somewhere unreachable? Time seems to me to gravitate more around composition of things: memory, atoms, direction, speed, than the conventional time concept. So why not replicate what was lost – and is that time travel?
