Hello m8, not sure this is possible lolSurprised But I understand what you meant, not sure those who have never heard of it will though!

I an out, I prefer to prevent paradoks Cool

I think i would go somewhen peacfull... dosn't metter too much, i almost like this time... Embarassed

But now siriously... a though question like that i won't be able to answer, the time is long, a maybe it's even longet then we think... maybe "Hamapaz hagadol" (as told in hebrew) wasn't the beggining of all time, but only the beggining of another part in the circle of life...
who knows how many living creatures could be over this universe even befor "Hamapaz Hagadol", I prefer not to deal with time and accept where i am...

 And if he wasnt your real grandfather? if you are adopted and you don't know that? if it's heppend in time, so it's possible... I won't belive the time has a weekness

Don't forget this gem of time travel theory from BILL & TED'S EXCELLENT ADVENTURE: (transcribed from memory, so probably not an exact word-for-word, but you get the point)

 

"We need your dad's keys.  Can you steal them?"

"No.  He lost them a few days ago.  Even he doesn't know where they are."

"What if we went back in time to before he lost them and stole them then?"

"We don't have time to do all that before the show."

"What if, after the show, when we do have time, we go back and steal your dad's keys and them come forward in time to where we are now and leave them for us to find?  We could hide them behind this sign.  Hey here they are!"

"I guess it was me who stole my dad's keys afterall."

"Now we have to remember to go back and steal your dad's keys after the show, or this won't happen."

"But it did."

Cracking film that, laughed all the way through it. The second one was a worse, for me, except the games with death, very funny that.

The thing that most got me thinking was the lines that you just wrote. It now begs the question, was there ever a 'first' Bill and Ted, or anyone for that matter, or is time circular?

The grandfather paradox is a proof that time-travel is just pure fantasy...  (my opinion only Sealedguitar_man_03, not only Catholics believe in God... Jews, Muslims, other Christian groups, etc. also believe (it's in the practice that we differ and that's okay).

It would be futile to go back as an historical observer to a time and place where you did not understand the language. For this reason alone, I would limit myself to English-speaking countries from the sixteenth century on and France from the eighteenth century on. I would like to go back to see the first performance of one of Shakespeare's great tragedies at the Globe Theatre and have a conversation with Shakespeare at the tavern afterward.

I would also like to practice my French with Voltaire.

 Nonsense! If you murder your own grandfather before he was able to sire your father or mother, it will turn out that your grandfather was cuckolded anyway by your grandmother and he was not the real father of the child. In the alternative time-line thus created, the real father survives and engenders the appropriate descendents, and you wind up turning out exactly the same. It is this propensity for the time continuum to correct and heal itself from any disruptions that makes time travel possible at all.

If you are really us in the future, then what number are we thinking of ?

Dang.  Good point.  I guess I have to study Greek before I travel the other way through time.  It can't be harder than chess.

Al!  Why haven't I leaped yet?

I find Charlie's argument as "proof that time travel is pure fantasy" just as comical as Ricardo's statement about what "makes time travel possible at all."  Really?  It is possible?  Since when?  And just because something has never been done, does not mean that it never will be done.  I'm sure there were plenty of very convincing arguments as to why man would never go to the moon.  And for centuries, they were right.  Personally, I lean more toward Ricardo's way of thinking that if we do develop the technology, I'm sure there are some inherent safty measures that we're not going to be able to do anything about.

 

Example:  Ever see the newest film version of THE TIME MACHINE by H.G. Wells (starring Guy Pierce).  His fiance is killed by a mugger in Central Park.  He invents a time machine to go back and get her out of the park before the mugger even appears, thus saving her (or so he thinks).  Immediately after reaching "safty" there is an accident with a horse-drawn carriage and she is killed instantly.  He rightly concludes, "I could go back a hundred times and watch her die a hundred different ways."  Time itself will not allow her to live thru an act of his time machine, because in doing so, his time machine would never have been invented thus creating a paradox similar to the grandfather one mentioned earlier.

 

My guess is that if one were to go back in time, it would not be possible to kill your actual blood great-grandparent before giving birth to your bloodline.  Something would happen to save their life and iron out the wrinkles caused by the travel. 

 

I saw an episode of Ray Bradbury Theater (I think - It might have been Amazing Stories or something like that) where a decendant of JFK went back in time to November 22nd, 1963 in Dallas and saved his many-great-grandfather's life.  Now this was a professor of history, so he knew everything there was to know about the 60s, but immediately after saving JFK, things started changing - like a string of tornados that didn't exist in the previous timeline. 

 

Time will heal all wounds, even it's own.  I seriously doubt that anything we will ever be able to invent will actually bring about the end of everything.  There are some laws which simply cannot be broken.  And we don't even know what the laws are yet.  Until then, everything about time travel is strictly theory.

 

Ever see DISASTER IN TIME with Jeff Daniels?  He goes back to yesterday, gets arrested and uses his one phone call to call himself (the himself that was already there yesterday doing whatever it was he did yesterday).  Upon arriving at the jail, the cop mistakingly believes that he somehow escaped from his cell and goes to put him back in it.  That's when the Jeff Daniels from tomorrow jumps out and starts wrestling with the guard.  The Jeff Daniels from yesterday asks, "How can you and I exisit in the same place at the same time?"  To which he responds, "Listen, can we argue the theory of time travel later, I really need your help right now!"

the question is that is time a dimension?

because if time is the 4th dimension then it must be possible to travel in the past but not to the future because it is has not yet occured. so is time a 4th dimension or is it man-made??

if we ever answered that question completly then we could travel back in time presuming it is a dimension. Try making a 4d shape!!!!!

For what it's worth, it was Einstein who said time and space are conditions of gravity.
