Yea i love that quote, also this one by Albert EinsteinBertster7 wrote:
Interesting.
I'm a big fan of physics stuff and read a LOT of books on the subject I had fogotten the Hawking quote, which I do really like and agree with : "a time machine will be built someday, but has not yet been built, so the tourists from the future cannot reach this far back in time."
Cheers for reminding me of that.
If you're interested in this sort of stuff I recommend reading into some of this stuff. 'A Brief History of Time' by Hawking is quite a nice simple introduction to all this sort of stuff, 'The Elegant Universe' is an interesting introduction to String theory (there's a crazy one for you to look up), 'The Universe Next Door' by Chown is very good too and the best of the lot - although VERY complicated and heavy going is 'The Road to Reality, a complete guide to the laws of the universe' by Penrose.
String theory is interesting stuff, check it out.

maybe they are here but they dont want to tell anyone so that they dont screw up the fabric of time. LOL.Spumantiii wrote:

How do you know that they aren't here? Maybe you are one but you can't tell us that u are from the future and therefore we are meant to believe that there are no time travellers in this period of time.Spumantiii wrote:

what if we are the first "wave" if you will. Like we will be the ones to discover it, go back in time ( which would start other "waves" of time ) idk how else to describe it but i've been thinking about that one for a while. It gets pretty confusing.Spumantiii wrote:

Time is a sequence of events, thus you can alter perception but you can't reverse a sequence of events that has already happened.mafia996630 wrote:
I was reading today how time travel is theoretically possible.

very interring stuff, so i wanted to know other interesting theories that other people know off.
None of that conspiracy crap please.
Hmm, moving along that plane would require shifting of the past and future cones along the plane, which would require reconfiguration of matter to ensure the continuity of the past and future, which would take time (unless you've got an example of a star trek style matter transporter), which would mean that you are actually travelling within the future cone. Moving sideways to a point where you own all the gold in the world would require either rewriting the past or transferring the gold to yourself through some kind of teleportation... and if you can teleport then moving the gold is a possibility within you future cone so it's not travelling sideways either.... IMO anyway.Spumantiii wrote:
think of it like 2 cones joined by their apexes. The joining point is 'now' .
The flat plane that exists on the same height as 'now' represents stepping sideways. The cones represent the possible path you've taken/ can take through time.

time is always moving in this direction |
the past (in any timeline) will always exist and cannot be rewritten, however, in theory it is possible to jump to a different future by moving sideways into a different timeline
confused yet?
using this principle:
http://en.wikipedia.org/wiki/Bohm_interpretation
it indirectly shows that small enough pieces of matter are in fact capable of 2 things,
moving to other timelines, or being intrinsically connected to similar particles in other timelines

That's not what Stephen Hawking has predicted. If you read the early posts in this thread carefully there is a quote about that very point.Spumantiii wrote:

If you had a time machine and could travel anywhere in time would you really pick this era?Spumantiii wrote:
