Time travel, right...

I was watching the Da Vinci code last night and discussing the possibilities with my better half, I said how cool it would be to be able to travel in time and witness these events how they really happend, like walking the streets while Jesus is on his soap box or Sitting in on a Templar Knight meeting etc... especially seeing Moses part the red sea (which I still believe was nothing more than low tide), but anyway... while time travel is a cool idea and cannot be dissmissed as impossible... IF someone did figure it out, be it in a Deloreon or a Phone box... what makes me sad is that someone would abuse it and start messing with stuff and end up screwing everything up.

Now this is where the theories begin, if you were to alter something in the past, lets say in my case... if I went back and killed Hitler when he was younger.... I would never have been born, since my grandfather was set to be sent to Burma until the US dropped "the bombs" and then he was reassigned to duties in England, Norfolk... where he met my grandmother.
So if I killed Hitler, I would never have been born ...so cause and effect I would not be able to kill hitler.

Now the question arises, would I be able to kill hitler?... or would the forces of time stop me in some way, or... would I kill hitler and create an infinite loop of time due to the fact when I kill him I would no longer exist to kill him therefore I never killed him.

So with the latter in mind, would it be a single event that has no bareing on anything or would the infinite loop cause some sort of wierd paradox that destroys all involved in the timeline change and alters history in a completely different way to the original plan.... or would it destroy time and the universe itself?

Just take a minute or 2 to think of the massive implications of the smallest action.... walk into a store in the 1920's or some such and cause the person in the line behind you to be 5 minutes late for work, the person then gets fired, his wife leaves him and they never have a child, this could be Bill Gate's grandparents.... now without old Bill being born... no microsoft...now think of the implications of that........ you are looking for 3 words...

Oh... My... Gawd!

Time Travel would quite litterally rule the world and most probably destroy it.... but would any of us know?... Obviously not.... here enters the possibility that it has already been done...., now you are simply looking for 1 word...

Whoa!

 

Here's your proof that time travel never, ever will exist:

Holocaust
9/11

ALSO!
You wouldn't be able to go back in time to stop something, because you already did.

CHEW ON THAT!

 

start messing with time travel...you might wind up on a planet in the city of nodnoL

 

Ah so you're saying that if it ever exists then someone would stop these events, but if the someone knows not to change anything then they would not stop it.... OR.... maybe they never happend and the person who invents time travel created them.

Chew on that

This is based on the theory that I suggested, you can't tell me to chew on my own theory
Also, this is the question, if I decided now to do it, you're suggesting that I would have already done it, so you are accepting the notion that future time exists and everything we do is already decided and has been done in future tense?

 

Ah, Bulgaria. Known for Animal produce and mineral wealth :-D

 

That's the classic Einsteinian 'Grandfather Paradox'.
There may a a Caveat on that, of sorts in the event(s) of parallel universes and as a consequence, time streams. The catch is, that once in the said time stream, you can't go back to where you originated, only to an infinitum of parallel time slip-streams.

So how do ya know the world/universe hasn't been altered and infinite number of times, hmm?

 

Exactly.

 

You can't Alter your own timeline,any interaction with even nuclear particles would cause a paradox so it just isn't possible

Like Phantom said you may be able to traverse to an alternate timeline and alter those events but its pretty fringe stuff.

Here's something more productive for you to think about Nedlamar:-D

If you have a sequence of numbers 1,2,3,4,5 and say the numbers go on to infinity 'you can count forever' so numbers equal infinity,so then you count just the even numbers 2,4,6,8,10 you can count the even numbers forever also so the even numbers equal inifnity.

BUT in the even sequence of numbers there are only half as many numbers 'for every one you count you skip one ' so how can the even numbers also equal infinity when there are always half as many?

 

You can alter your own timeline, but at the instant of the alteration it splits.

And killing Hitler is a bad idea. He gets replaced with someone competant, and we end up nuking Berlin.

Or the Nazi's beat us to the bomb, and well...

Hitler may have run it, but he wasn't the entire Nazi party.

 

according to dr who, there are certain events that *have* to happen, these events cannot be changed or stopped from happening (for example the holocaust). These kinds of rules stop the inevitable paradoxes from developing

 

Dr. Who is a metamorphising old git..well some of the time he's old. lol

Captain Kirk I believe has set the standard in time travel along with his successors Captain Sisko and Captain Picard.





















Jesus, we are debating time travel and using sci-fi characters to justify our positions. It's like having a conversation with Sheldon from Big Bang Theory.

Well I've been awake 15 minutes so this has not been deeply thought about but.... it's because there are an infinite number of numbers so whether you count the evens or odds or every 4th number, the count is still infinite, something to do with infinity multiplied by infinity equals zero.... so in actual fact there are no numbers at all :strong

Question for you Rikky..... and this will tax your knowledge to the very limits of human though..... ready?.......the question is this....

Given that god is infinite and the universe is also infinite..... would you like some toast? :-D

Another question for you about your post.... how is that more productive?

@motc7.... Whats this "We" ... I never mentioned sci-fi characters

@Triaxx... Hitler was a loose example and even if he hadn't existed and someone else did the bad stuff, it would have been different

 

Actually, time travel is possible, only into the future though.

Einstein's time dilation equation where T = 1/Sq.Rt.of ((1- (V squared/C squared)). Where C is the speed of light, (and I don't know how to type this in proper scientific notation, though I know there are character sets that would help with this).

So if you set off at 185,000 miles per second, for a year, upon return, 8.54 years would have elapsed. Don't ask how you would achieve that speed, that's a whole 'nother subject.

Anyway, travel into the past, can no do. Into the future, plausible, but you couldn't return. But you could buy yourself a nice portfolio of securities, take possession in certificate form, find a real good hidey-hole, and maybe return a wealthy person. :-D

Better yet, take the certificates with you, duh.

 

Actually you can, (in theory at least), travel in reverse, (i.e. past), without contradicting Einstein. The only catch is that you or the subatomic particle, (e.g. tachyons) has to already bee traveling faster than light speeds. The time factor in this case operates in the (-)ve.

A discussion on the subject exists here:-(PDF format)

Notice the laughing smiley after I said it:-D There is no answer to the infinity conundrum,its just something weird about using infinity in maths equations,infinity is a pretty pointless concept.

:-D

EDIT And tachyons also can't go slower than the speed of light

 

Yes, that's true. Maybe they theoretically could, except, there's that light speed barrier problem again. Maybe one would have to jump to other dimensions, and as far as we, the observer are concerned, cease to exists, (in our universe), and then pop out in some other point in space-time. If this were somehow possible, it would take no more energy to go to other side of the universe, (and time) as to move a millimetre and a microsecond. Mind you, you would 'prolly need Black Hole quantities of energy, (whatever that is), to make the jump.
I tried crawling under the sink to see if I could meet myself in the future, but all I found was a dang awful smell!!:crap

On the question of infinity:- Infinity is merely a theoretical concept. As yet, we have yet to discover anything or situation that is actually infinite. Even the universe itself is finite. Half of infinity is still infinity - try smoking it.:-D

 

I'll see your infinity and raise you one. :-D

It's my goal in life to count to infinity, twice.

 

That video I've seen before. the guy in the film you could barely see with the sunlight shining behind his head, and the guy must have had arms that were 12 feet long to hold out the phone that far from his body.

In short, it's a steaming pile.

 

I had recently read the book "Physics of the Impossible" and time travel was discussed as Class II impossibility: http://en.wikipedia.org/wiki/Physics_of_the_Impossible There is further discussion on time travel at: http://en.wikipedia.org/wiki/Time_travel
