Time travelling will happen

...according to Stephen Hawking's statements. The astrophysician told that time travelling is possible and that human will try it in future. He says he's convinced by it since a long time. Remarkable: he only sees travelling in future as possible, travelling into the past he considers pure nonsense as this would break the fundamental rule that cause comes before effect. Feel free to give your opinion on this :thumbsup:
 
Well, I think it may actually be more feasible to travel to the past, as long as you were in "ghost form" (like Scrooge in A Christmas Carol) and thus not able to change anything ...


If we are able to travel to the future ahead of everyone else, doesn't that assume a kind of predetermination, which seems to mess up the idea of free will?
 
It does. But maybe free will and determination are on some sort of working combination, as has been discussed here somewhere? Travelling in future would certainly be a life's sacrifice until the technology will be so sophisticated that it passes time in a flash. Hawking sees it done that humans would provide themself for a kolonisation and possibly return when disasters have occured on earth.


There is certainly something to say about going into the past as a ghost. But also ghosts can change something imo.
 
Oh it will be some time yet sellingmysoul. We so don't have the technology yet, not even close!

I read the article and thought it was interesting, but he is talking about something very mechanical, not 'metaphysical' in any way. He is talking about how in theory building a superfast spaceship you would be able to fly fast enough to get to the edge of the galaxy within a single lifetime instead of hundreds of thousands of years - travelling at 98% of the speed of light...


...Having taken six years to reach its full speed of 98 per cent of the speed of light (650million miles per hour), a day on board the ship would be equivalent to a year on Earth, he said, allowing those on board to reach the edge of the galaxy in just 80 years. But the ship required for the journey would have to be massive to allow for the required fuel...


Or, presumably you could fly half way there and half way back in a lifetime and by the time you got back many Earth years would have passed and all your friends and family would have died years ago. So, if that's travelling into the future.... no thanks!


However, it is a fun idea to play with and a good illustration of how time and space are both 'relative' and time is not absolute as we usually think of it.
 
Hi all,


At least in terms of "Spiritual Time", I believe it might be something comparable to when we doze off for not more than a few seconds but run through a rather extended dream... The "notion of time" is different, but linear nevertheless. Perhaps the same might occur regarding the "relativity of time"??? I can understand Stephen Hawkings' view regarding the impossibility of travelling backwards in time. As for travelling into "relative futures", yes, I guess it might be possible.


Tanguerra, I was thinking about something you said in your post in our previous correspondence regarding the "illusion of things". Would it be an "illusion" or a "creation" I wonder...? :)
 
Not quite sure what you mean Charles. This is basic Einsteinian physics. It would be 'reality' as we know it, neither illusion nor creation, just maths.


If one were to do as Hawking describes, and build a super-fast space ship and do a near light speed lap of the galaxy and come back to Earth, more years would have passed on Earth by the time you got back because you have been gobbling up so much 'space' in your super fast travels, you have also moved through time more quickly than usual. Because space and time are 'relative' to each other - that is intimately interconnected - you can't have one without the other. This was the big insight that made Einstein famous and it has since been proven more than once with empirical observations of the movement of heavenly bodies and so forth.


Meanwhile, while you've been away on your epic voyage, the Earth would have gone around the sun at it's usual, sedate sub-lightspeed pace but everyone on Earth would have aged considerably more than you, while you've been zipping along, clocking up 'light years', or even have died and a whole new generation been born while you were away. Therefore, you would be going 'back to the future' when you landed back on Earth.


Don't worry, it confuses me too!
 
Hi Tanguerra,


I have no problem understanding the relativity of space-time, as long as the realtivity applies to "relative futures", not to "simultaneous lifetimes" or "simultaneous time"... What I was mentioning was something I have read others say here and that you also said regarding "everything being an illusion", so my question was: would it be an "illusion" or a "created reality"? :)


Wonderfully entertaining to ponder about all these things, isn't it?
 
I watched a programme on Discovery a while ago about future inventions. Among them was time machine. I can't remember exactly, who the inventer was or the technical part of, but he was a professor of physics (which means to me that he must have some idea of how these things should work in principle: angel).


Anyway, he believed that he was going to be a time machine that could bring you back in time. However, the furthest you could go was the time when the machine would be turned on. He didn't think that people would ever be able to travel, but he saw great potential for being able to transmit information from the future to the past, like warnings of coming disasters and such.


I'm not a physicist, but I see one fundamental problem with all this talk of possible time travelling. In regards to the case above, wouldn't we have gotten messages from the future already in case time travelling was realistic?

I agree with you Sunniva! I'm certain, that if time travel was to ever become physically possible; we would be overwhelmed with countless tourists from the future. I seem to remember a film from around 1980, in which a man, who had lost his wife, caught one such tourist and used their "device" to go back and save his wife. The visitors appeared in expectation of witnessing a huge asteroid impact from the comfort of his inn. Has anyone seen any such "anachronistic" visitors lately?

Some have (dk...?). But that doesn't necessarily mean time travelling in human form is realistic. Or is at the moment.
 
There was a South Park episode where people from the overpopulated future came back and started colonising the 'present'. Hillarious!
 
What would be the purpose of time travel? The ability to look into our past lives, or to see into the future, is already within each of us. it's a great learning process. I think even if a person was able to go back physically, they could not change anything, because it's already happened. If you were to travel to the future, you would see nothing more than a possibility of what things could be like, because of free will. People would be disappointed after awhile.


Yes, actual time travel would be...well....like the big bang theory all over again. :eek: :freak:
 
The purpose would be, according to Hawking, to have a backup of humans in case of extreme disasters or something like that. You can compare it to your PC backup and exploring free storages somewhere in a system I guess. But then with the PC the aspect of time isn't involved.


So human time travellers would be going towards the future while normally future is coming to us, right?!
