comments: re: I'm going to see the launch of Apollo 11..... So you go, and when you arrive at the launch site someone (anyone) sees you. They don't know you are from the future, But the fact is they see you and respond to your presence. In the normal time line you were not there, thus you have caused disruption. Doesn't matter surely that you were wearing sixties clothes and tried your best to fit in surely?? This does my head in thinking about it. Anyway great site, very interesting You have influenced time and when you return your 'office' may well have disappeared.

"Thanks for visiting my web site. It is good to hear from people who have visited my site.

I know what you mean about "does my head in" - it does mine, frequently.

You are quite right that there is a paradox when you time travel even if you try to avoid doing anything that might change the course of history (or is it the future?). I have tried to describe this in my story "Money,Money,Money" where there are two endings - one where things are ok and one where they are not."

comments: Go through the dimentions, when you reach the 4th time is added. The only explaination I could find was that the 3rd dimention starts traveling at the speed of light. Once this happens, things move on their own. There is no possible way of going back in time for if and when you reach the speed of light again, time stops, your back in the 3rd dimention, perminatly. Now to travel forward in time, I have found some proof. Say the time machine is your body(B). If you can slow down the time inside B, without disterbing regular time. Your body will fell like it traveling through time. If slow down even more, 100 years could past before you even know it. Truly, to slow down your B isn't that hard. New science answers say that there is a Master Cell in our body, if you can trick that cell into thinking time has slowed down, problem solved.

"I'm not sure I follow your definitions of the dimensions. The first three are all at right angles to each other and give us right/left, back/forward and up/down. The fourth dimension can be considered as Time although the fourth 'spatial' dimension is at right angles to each of the other three but this is impossible to imagine in our three-dimensional universe. However it is possible to see a shadow of a four dimensional object. Just as a shadow of a three dimensional object such as a sphere is a two dimensional object a circle or ellipse so a shadow of a four dimensional object would be a three dimensional one. Have a read of the book on Hyperspace by Mickio Kaku -details on my Bibliography page.

I haven't heard about the master cell in the body presumably this is a bit more practical to slow down your body for travel to the future without having to resort to cryogenics :)"

comments: Hi. Like the web page! I'm preparing to do a talk on time travel. Not too clueless as I've done physics before at uni, but I'm looking for good current information on viable designs/ideas for time machines. E.g. rotating black holes, and so on... Do you have any good links handy for this? I'm using google.com to look for stuff, but there's an awful lot out there! thanks for putting up a cool page! alex
timetravel:yes
website:yes

"If you want information on "How to build a Time Machine" then I would look at Chapter 11 of Michio Kaku's book Hyperspace and Chapter 14 of Kip Thorne's book Black Holes and Time Warps: Einstein's Outrageous Legacy. Full details can be found on the Bibliography page of my website.

As to the internet you might try Steve Preston's web site that you can get from my Links page. I am not sure of any others but it is the sort of thing that may be on David Deutsch's page.

Like you I also use google but you might want to try askjeeves as well."

comments: Regarding your article about "Holiday to The Past", the time traveler spends his first 25 years in 1972-1997. Then he spends his next 20 years in 1797-1817. Then he comes back to 2017 and spends 30 years till his death in 2047. Now aren't you assuming that after going 200 years into the past, the time traveler will return back EXACTLY 200 years into future ? What if he returns to 190 years into future (year 2007) ?
timetravel:no
website:yes

"The reason for returning exactly to the same time was so that the same time was spent relative to the Cosmic Time as the Time Traveller's time. When he returned to 2017 all his friends would say was "where have you been?" If he returned to 2007 he would only have been away for 15 years as far as his friends were concerned but he would have aged 25 years. I did not want to complicate matters at this point of the web site."

comments: comments: In my opinion time travel is simply impossible. I doubt even if God excists that even he could do it. Don't forget time is eternal and never stops.The paradox's and potential problems time travel would create are beyond our understanding. There is no way to prove the theory but plenty of theory's and basic facts to disprove it. The basic problem is that it is probably every human's wish to go back in time and undo mistakes made in the past. If you believe in God then why didn't he do it. Because it is impossible.
timetravel:no
website:yes

"Time has only existed since the start of the Universe at the Big Bang and, according to cosmologists, could stop if the Universe ends in the Big Crunch.

It is true that it is easy to produce paradoxes with Time Travel unless you use "the get out of jail card" called parallel universes but just because we don't see how time travel could work without creating paradoxes doesn't mean to say that they could easily be avoided if only we knew how. After all you can watch a magician's trick and believe what you see is impossible yet it is simple to the magician and not magic. If it were magic then David Copperfield would be in the Whitehouse and Paul Daniels in Downing Street!

Also, God would surely have no need to return to the past to correct mistakes as I believe he doesn't make any."

comments: Time travel is nonsense.No one from the future has come back to visit.The obvious and much repeated paradoxes should be sufficient to kill the idea. I have yet to hear any lucid definition of time from those who entertain the idea. Until one can clearly understand the nature of time any discussion of time travel will be pointless. Clearly, time travel must presuppose an infinite number of co-existing universes. There is no basis for this idea. Don't let me discourage you, I also don't buy Einstein's (Minkowski's) block time (4th dimension idea), but am in agreement with the idea of time dilation and the inexact nature of time. Read Paul Davies book "About Time" for an overview of the subject. Bob Mac Keil
timetravel:no
website:yes

"I agree that the only way that time travel could work is if there were parallel universes. This way crossing between would create no paradoxes. I don't believe in them myself. Too simple an answer. There would need to be too many of them as well. There is no evidence for them and unfortunately to prove they exist would surely mean travelling to one but then since you can't return to the one they left then you couldn't tell anyone! Neat for those theorists who believe in a theory you cannot prove. You can't prove them wrong!"

comments: Re your holiday trip to Crystal Palace idea. It occurs to me that there are an alomst infinite amount of ways that a seemingly innocuous trip such as that may change the time line e.g. the person at the end of the queue may have decided not to wait in line, and gone and done something else instead - possibly got mugged, whatever. the bacteria from the traveler, plus an germs etc may have introduced a virulent epidemic, the list goes on, the only way around this that I can see is the alternate universe theory, but would you return to your original universe, or the altered one, or would you simply keep skipping through alternate realities!
timetravel:yes
website:yes

"Even the most simple time travel trip could cause the smallest change to the time line and therefore alter many of the subsequent events. I tried to use the Crystal Palace story just to show the idea of a simple trip. I then used the stories in the Let's Get Rich section to begin to explain the changes that might occur to the time line and also to bring in the subject of alternate or parallel universes."

site:From another time travel sight not sure of the adress
comments: I prepose this If I (or any of us visiters) were to visit this reply page and find that we had visited it before but we had no consious memory of it would this lead one to beleave that it might have been visited by our future or past self or even our alternet self from another or more dementions. And if we could be reading messages from another version of ourself's. Would this not offer a means by which we could exchange information with another of ourself's with out risking a parodox. ( I.E. My future self records a message for me and leves it here knowing that I will visit this sight at some time in his past and he has a memory of reading this message in his past but my as of yet future. would this be possible? and whould it cause a parodox as has been preposed. I do so enjoy this sight and hope to find a semilar sight that offers a chat room as the subject fasinates me and has for many years now. I pray that we are able to find answers and solutions to the outstanding problems with time travel and do not find ourself's at some future date were we find ourselves in a position like the one in the movie Mellinium were humanity has reach a point in their development were they have stripped the resorces of our plant and have become desperet enoough to risk parodox on a regular and on going basis in order to try and save our race and our planet. Till we meet in the future or if we have already met in the past I bid you good tidings friends. TAGz333@yahoo.com feel free to write to me any time if you would like to descuse the subject further till then.
timetravel:yes
website:yes

"What an interesting idea. It does seem possible that your future self from next month could go back in time to leave a message on this reply page today. You could then read it tomorrow. There are no paradoxes from the point of view of today.

"Suppose that it is now next week you would have a memory of reading the message last week even though your future self has still to return to the past and write the message. Still no paradoxes.

"Now it is the day after your time travel trip to the past and you have memories of reading the message and writing the message although they are in the wrong order! There still appears to be no paradoxes but we have assumed that the future is pre-determined.

"What if it is the day of your intended time travel trip and you do not make the journey. Do we now have a paradox? You have a memory of reading the message but it cannot have been you that wrote it. Or perhaps it is but you make the trip at a later date. So maybe not a paradox. However if you were to die before you made this time travel trip then surely this does produce a paradox. Or does the message just disappear from history?"

comments: Nice site, i really liked that story with the 3 georges, kinda like one of the ideas ive got running through my mind. I still dont think humans have reached a high enough understanding of what time is to be able to manipulate it and not be hindered by it.
timetravel:yes
website:yes

"I am glad that you liked the story about three versions of the same person meeting each other at the same time. It took a while to work out but I hope it shows how the meeting for one person is new but for the others has happened before. Also it throws up some interesting questions such as the one about the biscuit!"
