    I've been thinking again. After watching that show about multiverse and how time travel theory is a real thing, then do we have free will? Yeah, I know we've all done the determinism debate before, but did you do it knowing time travel was theoretically possible? It's like bringing the sports almanac back, you know what's going to happen. It's fun to wonder these things.

      Editing … Time travel as far i read before is only into the future possible (using a vehicle close to lightspeed), getting back in time not due similar to mentioned reason in "time machine" flick. Would like to see what parallel worlds are like, which are told to exist, probably won't be explored until we exploite wormholes.

      Editing … Well there was this quantum mechanics scientist dude (forgot his name) who says the brain uses quantum mechanical mechanisms to function. Because quantum mechanics are not predictable our actions, thoughts and decisions would not be deterministic. I really liked how he explained it and it kind of blew my mind. Old and wise scientists know so much that they can see the limits of what they know but they know enough that they see so much wonder in the workings of the universe. It is quite poetic that religion and science can sometimes come to the same conclusions.

      Editing … There is also the Buddhists that think free will exists but they also think an untrained mind is less "free"/more predictable/reactive. Once they train their minds more, people can become more free and in control of their decisions and thinking. I guess the “untrained mind” would have just as much free will because quantum mechanics still functions the same for an untrained brain as for a monk. But the monk would consciously be able to control his mind the way he intends, like how an athlete has more control over their body than a couch potato. So there is the randomness of quantum mechanics that give a lazy untrained couch potato free will to get off the couch and exercise. But because he has not yet trained his mind to be able to control his mind the way he wants, the couch potato is driven by his basic animal instincts to veg out infront of the tv anyway. The free will sometimes allows the couch king to want to change. Slowly he trains his mind to exercise once a week, then once every three days and suddenly he is a buff and crispy potato wedge all thanks to quantum mechanics.

      Editing … @Alex apparently if a black hole is spinning then it's possible to travel back in time going through a couple of multiverses. So if it's possible and I know that couch potato didn't get up off the sofa will he ever get up off the sofa?

      Editing … Yeah, somebody finally worked out Einsteins maths, I think it took 50 years or something. In theory, proven with maths, you can go past the point where time freezes and it actually goes negative. This is where the white hole makes the backwards time travel possible. The professor had a really good diagram that the computer simulated and it's a lot easier to get your head around once you can visualise it I suck at explaining at the best of times. I'll have a google after work and see if I can find it. It's like a bunch of triangles, each one a multiverse, all stuck together showing the singularity and event horizon bordering each other.

      Editing … mmmh I'm not really looking forward to a more technologically driven world so big no for me. Except maybe if I could go so far into the future where people have learnt to have a healthy relationship with technology where technology is just a tool and not a way of life or an absolute requirement to participate in society. And also no fucking with the fabric of reality and nature and science for science's sake. No androids, no humanoid robots, no cyborgs, no clones, no genetic experiments, no chips augmenting your brain, no genetically selected humans or designer babies, no auto tune, no ai assisted music, no Monsanto it’s-so-good-for-you-because-we-say-so super food, no space travel, no Mars colony, no corporatocracy, no communicating with aliens… also no fucking with time or time travel. :-P Just a simple world where people are nice with things like eating and sleeping and having fun in a normal way your grandmother could understand. If I can have that I don’t care where I am or when I am.
