Hi you have actually hit on one of my favourite subjects here and have asked a few questions that I have, usually aided by the logic that comes with vast quatities of alchohol, discussed with friends and believe i have the answers. . Here are a few of the most popular questions and what i believe to be the most logical answers 1) If i went back in time could i alter History? A: Is answered with another question. How do we know we havent? My logic behind this is that if someone went back in time and altered their history they would be the only ones aware of it because the moment they changed an event that occured in their past it would become our actual history. Take the life of Christ for instance, he may have been a one size fits all religious nut, cue time traveller appears to him and guides him through life, giving him a heads up every so often (stories abound where christ seems to be forewarned of events and occurences, like where to cast the net to catch the fish and his forseeing his betrayal at the hands of judas. The actual time travellers history would be changed but only for him because those changes now become a part of established history for everyone else. Another example of this is: Could i go back and Kill Hitler? Well we dont actually know for certain that someone didnt do we? Think about it, Hitler commited some terrible attrocities, but maybe in our friend the time travellers history, he survived the bunker and released a nerve agent into the air wiping out half the population of europe. Our friend the time traveller cannot act before the Bunker because we would have lost many of the inventions and innovations that were brought about during the war, so he waits until a point in Hitlers history where he would be able to carry out his mission in relative secrecy, after the inventions but before the mass murder of half of europe. Now that becomes part of our history. 2) Could you go back in time and kill yourself? A: Would you? Could you kill anybody? For someone to kill another person there has to be something really wrong with that person or they have to feel there is no other alternative (like the lives of your children being threatened). I dont think many people could, or would kill someone in cold blood. Now consider meeting yourself, if its that hard to kill a stranger it must be ten times harder to kill yourself especially knowing you may possibly cease to exist. Would you honestly do it? Same with killing your parents, could you do it? I couldnt for two reasons, im not a killer (just a little mad) and im not suicidal. 3) If history can be altered would the time traveller then have his past history altered and not have to take the actions he did? A: No, because the Time traveller is working in his present at all times he would not be effected by the change in history untill he returned to his own time, but then he would be the only one aware of any change. 4) Wouldnt someone go back and give themselves the winning lottery numbers? A: Again we dont know they haven't. Consider this if your future self came back and gave you the lottery winning numbers and you won 5,000,000 (whatever you currency is), would you be daft enough to let it out that you got the winning numbers from your future self? Firstly you would forfiet your winnings for cheating, and more than likely spend a while in the psycriatric ward of the local nursing home. I also believe that if time travel becomes possible it will be the end of gambling and games of chance completely. 5) If time travel becomes possible wouldnt they leave some traces of having been here? A: Yup and there are a lot of assumptions made that UFO/USO are alien in origin, maybe they are terrestrial albeit from another time. At this point i'm betting you wish you had a time machine so you could go back and tell yourself not to ask this question because that idiot biggabum is going to write the most longwinded and dull answer you have ever real Take care


Lol at your last line.... I actually read through ALL of it. Very interesting. Seems that you have done some solid research on it. It is really very complicated. Agreed that people do not just kill anyone in cold blood, but there are all kinds of nuts who will do anything- they can even kill themselves in past. Well time travel might be possible, but the real question is- can it prevent ageing? Like, let's say I turn 60 and I get wrinkles on my face. What if I travel back 30 years then? Will I be younger?


IMHO no. You see no matter where you travel in time you will always remain in your own personal present. So for instance if you are 60 now in 2011 and went back to 1981, you would in fact remain 60. I can see what your getting at though. Your actually thinking about turning back time, or more commonly known as time reversal (well it is by me anyway ) Its a slightly different subject, and while i belive that someday time travel may be possible im not sure if we would ever be able to reverse time. If you think of Time along the lines of a book, and everytime you turn a page you glue it down, so it cannot be re-read. Now that page still exists in the book but you cannot access it or turn it back and you cannot unglue it because you canot open the page to do so. Now create a machine that can make a hole in that page and you can now see and re-read that page, and thats my theory on time travel. If this subject fascinates you there are a few subjects that are linked. Timeslips are cool, the Bermuda Triangle (the jury is still out on this, even if some of the stuff can be explained away it doesnt mean that those explainations are right). There are also a series of volumes (12 or 13 I think) of an old magazine called The Unexplained that crop up on ebay frequently, its a little dated now but it has some fascinating subjects in there.


Its really fascinating. I always believed time travel was possible, but I kinda thought I could turn into a kid again.... So its kinda disappointing. But then, it would mean that we can live forever- which is not possible. Do you think if someone travels faster than the speed of light, they can break time barriers?


According to einstien yes. Mmmmm theory time, If you take a wheel and mount it with lasers that are angled to cross beams just within the rim of the wheel, turn them on and then spin the wheel incredbly fast (but dont let Hotpoint build it or it will pack up the week the warranty runs out), it may be possible to artificially increase the speed of light, there fore, my thoughts are, would this create a window within the wheel that looks into the past. Probably not I think you actually have to be going faster than light. Some people also believe that black holes are so powerful that they bend time and that if you could survive a black holes gravity you could in fact travel in time. Which leads back to the LHC which can make tinsy tiny black holes, so if einstien is right, we do have the technology to do this but just have to find a way to harness it.


Annnnnd.... I believe Einstein's always right :)


Weelll he pretty much covered his arse by saying that everything he was saying was relative to our laws of physics. You have to remember we havent been around for very long compared to, say, the dinosaurs, so imagine a race of perhaps Aliens, or even ourselves some ways down the line that may have been around (as a race) for a couple of million years, their laws of physics may differ from ours. Dont forget in the 14th century it was an irrefutable FACT that the earth was flat and when you got to the edge you would drop off (if i remember right they had only just figured out it wasnt square, hence the saying four corners of the world).


Time travel into the future is possible... and has actually been done already. It's called time dilation (Emily's next topic?!). Essentially, things moving at higher velocities actually move through space-time slower. Things like GPS satellites and even the people aboard the space station move at higher velocities than us here on the surface, so they all experience a tiny bit of "time travel". If you were to increase velocities to nearly the speed of light the effects of time dilation are much more great. I'm not sure on the exact numbers, but moving at 99.99% the speed of light would take something like 4.5 years to get to the nearest star and another 4.5 years to get back. So to the astronaut only 9 years would have passed, but back on Earth it would have been 500 years. And who says we can't live forever? Imagine if we develop technology someday to "upload" our brains into computers. We could develop robotic bodies and upload our consciousness into the body, and essentially live forever. Just replace "body parts" as they go bad, or replace the entire body and repeat the upload process each time.


Interesting point and I remember reading something similar. I disagree on the live forever thing though. A couple of reasons, firstly there's the problem of overcrowding (mind you if we lived indefinately traveling greater distances through space would be possible although rather boring. I lose interest driving 20 mile down the road...mind you that is to the mother in laws so that might have some bearing on my disinterest). Secondly while the first couple of centuries would be ok I think after 3 or 400 years it could get a bit tedious. (Again dont let hotpoint make the robotic bodies if you want spare parts, one bloody year and they dont make them anymore, and the machine is flippin obsolete, why?? coz it was rubbish and that part went on them all and they run out!!! Ooops sorry been phoning them all day... not happy )


The only reason I'd want to "inhabit" one of the cylon bodies (:D) is so I could travel through space and just explore new worlds. No need for a spacesuit... hell no need for a spacecraft. Just build in a propulsion system and go into hibernate mode until you're there!


Mmmm, you know a version of what your saying could actualy be feasable now (at least we have the technology anyhow). Modern science can create a plastic heart (its only tempory at the moment but we all know that now its been done its only a matter of time before permanent artificial hearts are made). they also have the human nervous system mapped out, they have machines that can replicate the functions of the kidneys and liver, and the understanding of the human brain is far greater now than say 10 years ago. In theory they could build an artificial body with a working nervous system (using fibre optics perhaps!?!) and blood supply. All they would have to do (yup simples ) is transfer a human brain from a body into the artificial body....i volunteer my mother in law to try it first...oh crap maybe not if it works i could be stuck with her forever....


omg my brain will burst with so much info !!
