Last night i watched a documentary i'd downloaded called
Time Trip. First it told me of Newton's ideas that time moved in a straight line and governed us all, with no room for movement, and that our futures were pre-determined and had been since the beginning.
Next came Einstein's theory and, though it sounded mental (like Newton's doesn't) it's important to remember that he really did split the atom and create nuclear power. If i have any of this wrong i apologise. He said that time moves differently in different places, for example it moves slower in space, and all of our ancestors and future relatives and so on are alive right now, occupying the same space. You'd be able to move forwards through time but you couldn't come back, to move back in time you'd need to move faster than the speed of light. So, basically, time travel is theoretically impossible, as it was also said at one point during the documentary that you wouldn't be able to venture further back than the creation of the time machine. I'm not sure how or why, but i'm going to assume that's true.
Apparently some scientists are thinking about how they can create a virtual reality of the past, like - i thought - the Matrix or Westworld. The people in these realities would have their own thoughts and feelings. The only thing with that, i thought to myself, is that it would be some scientist's impression of the past. I mean, take dinosaurs. We have got things wrong about them before, who's to say we wouldn't be entering a world of almost make-believe. What about the texture of their skin, for example, or their colour? You might not think it's important but it would make me doubt everything i saw there.
Also there was one other drawback, they finished by saying, if there are thousands or millions of virtual worlds, the chances of you turning out to be a real person from the original world is slim, therefore you might not be real. I think at this point i'll leave that with you.
