Ok, As we near the future we foresee, I've been fascinated by the Time Travel, Time Machine and past and future.
I am more than extremely sceptical about time travel and the possibility of it ever being possible :
1) because time is a human concept, while it might seem like time exists it is merely intervals relating to the position of the sun/moon in relation to the earth as it travels around the sun. The earth is covering the same ground, yet we think of time as linear, so while things may have happened in the past who is to say there is a way of distinguishing past events to travel to them? ie the same point in our orbit round the sun has been reached X times, how can you possibly convert a point in time.
2) as per the end of point 1, how could you define a point in time.
3) wormhole theory is just that, besides anything else lots of people in the past are dead unless you believe there exists infinite points in time that you could travel back to.
4) there are three physical dimensions, we know we can travel in directions but how do you propose that would work in time?!?!
5) the structure of the concept of time is CONTINUOUS, we talk about the "present" but in fact there is no "present", only the past and future. By the time you've typed "present" it is the "future" and then that becomes the "past" and so on. Since time as a concept doesn't stop, unless you believe that old trick with the atomic clock which has time travel as the explanation when in fact it could be any number of things including a distortion effect caused by the speed travelled at, unless you believe the clock was in the past and we were just seeing it's physical shape later than it actually was - if there is an easy way to put that please do! Do I know if the house I am in now exists in the now, the past or the future as it is the same house. But unless we start tying ourselves up in knots about what objects are in the here and now then we have to assume everything occupying the universe at this moment in "time" is in the same time.
I do love the atomic clock argument, as if there is a cause and effect relationship ie that it proves in some way time travel is possible.
6) and the macdaddy of the arguments against time travel. If it were ever possible, and people believe that there is a future to go to as well as a past, then why have we not been inundated with time travellers in their police boxes, phone booths, USS Enterprises etc?!?!? If it is possible then are we to assume noone has yet worked it out!?!?!?
7) to me, unless there is physical evidence something can be done or has happened or does exist, we have to assume it doesn't. There is no evidence god exists so we have to assume he/it doesn't. We've not been visited from people in the future, or the past since if there is a past to travel back to then there is every chance they might discover it. But then the world seems pretty consistent to me, if you've ever seen that series about the Bermuda Triangle where reality changes, or indeed Butterfly Effect (excellent film), then why does the world seem to be as it has been, slowly progressing or not as seems to be the case, or perhaps it keeps changing and there's no way of knowing as our memories etc seem the same but could well change and if we wrote down reality and it changed then so would our written account of it.
Time travel is the realms of fantasy until proven otherwise, just like god and heaven, immortality and other things people wish were possible/exist. It is one of those things people will talk up as possible since there is no way of disproving it. Timeline yesterday was quite a good watch, comparing human teleportation with a fax even though the sending fax tells the recieving fax what order to put dots on a page, not what order to put bits of a human back together in and so it is completely different. I've typed into a keyboard, people can see what I can see so it is merely a case of what I am typing being stored in a data format that other PCs can share and display, or I can transmit the orders via text, fax etc. It's not quite the same with living organisms, if at all. Save time travel for fantasy novels and films, space travel is possible but time travel is based on a great number of never gonna happens
For starters we can try putting him in a nuclear reactor?
