The greatest most common paradoxes in the world

Yeah, basically but its gets more complex than that as you start relating to these other people who tread on this path as you. and how this whole series of events wasn't cause by a preset path but rather the consequences of your own actions while going into the past even though you haven't gone into the past yet

so what your trying to say is that even if you go back in time, whatever you do will have no actual effect?

but surely an american solider/scientist could go back and pass on knowledge of how to make nuclear weapons to the Japanese before WWII, then when hiroshima and the others were nuked, the Japanese wouldnt simply quit the war, but would nuke America

this means that some people at least could change the past (its not as if the nuke will miss

No the whole idea is that its absurd to think u can change the past. If u did then there would be many different future scenarios wouldn't there?! If u go back and change the past then u can't come back into the future because the future will be different now. Its paradoxical

well I guess that is what this thread is all about.....paradox

 

Not only is it a paradox, it is impossible (unlike a lot of other paradoxes)

 

John, just a little off topic here. When you sit on the sand at the beach and look back at your own and other peoples pasts what are you actually doing do you think?

Could it not be suggested that in some way you are travelling back in time to those past events and feelings?

When you think of the past are you in some way changing your past or are you just observing your past thus changing the present?
I do understand this is a very individual thing but as you know any change in the past changes the present.

Have you ever experienced that surreal feeling when thinking about a powerful event, either good or bad in the past. Is this feeling a sort of "present changing" feeling because your thoughts aabout the past are changing the present?

 

No. Back then they were not memories but actually happening.

U cannot change the past without changing the future. The latter.

Yes. U are drawing on emotions which u have felt in the past again. As u know we have immense power to change the present and future.

 

Who says that they haven't already? For all we know a person from the future could have gone back into time to tell Einstein that E = MC2. Or maybe someone went back into time to give us information on how to create atomic bombs. What I'm trying to get across is is that the past is set forever. The past cannot be changed therefore the future will stay the same.

EX: Lets say the dinosaurs died, which we believe to be a cause from a large collision with an asteroid. Lets say it wasn't a collision with the asteroid but rather a man made weapon. Someone went into the past and setting off an atomic bomb which wiped out all living organisms on the surface of the earth (including dinosaurs). Now this person who went into the past may not be born for another millenium from this present, but the fact is, he's going to go back into time and wipe out all the dinosaurs at some point in his life, even though this person has yet to be born, his tampering with the past has effected the future. But lets say someone else goes into the past to try and stop this person from wiping out the dinosaurs. Its not going to happen, something is going to prevent this "Dinosaur-saver" from stoping this madman from setting off the atomic bomb, since, as we know, all the dinosaurs are extinct.

P.S - Isn't it possible that maybe we haven't gone back into time?

 

Are we forgetting that the universe does not know time as we do? What is the past exactly, and what is now specifically, and future means what ... to the universe. When the lightening strikes, and later the thunder roars, is this not a paradox of sorts. Does this not tell us something about time? Say what? pmt

 

POSTED BY JOHN: As u know we have immense power to change the present and future.

Surely you jest! We have no immense power within ourselves alone to change any thing. Just because we do something different does not necessarily assure that the bottom line will be so different. Come on, John, if you have immense power, tell us about it.

vortox, no weapon we currently have could have killed the dinasaurs

a nuke being set of, would result in high levels of radio-activity whereever the nuke effected (centered aroud wherever the nuke was set off)

of course, its possible that someone from the future could have gone back and killed them, to allow his ancestors to evolve without dinasaur competition)

 

U just said that the past is set forever and then u tell me u can go back and change it. I haven't got a clue what world ur living on but pray tell!!!

 

The universe doesn't 'know' anything! It cannot think.

huh???

Absolutely not. One travels faster than the other

I don't think so

"This statement is false."

If it's true, then it's false. But if it's false, then it's true.

What is the bottom line? Haven't got a clue about the terminology u use!!! Because we do something different is exactly why we have the power to change present and future. U also have the power and u have displayed it by changing the future by posting on this thread there and confusing the hell out of me

I got it!!!! Ha!!!

To go back in time is actually to go forward.......what?? you say!!!!!

Well according to relativity if you travel at significant velocity relative to a stationary frame time slows thus as you travel the present for the stationary frame is progressing faster than you are......so after a while you have travelled forward to the past.......of that stationary frame

Do I get a gold star or what

Hence the paradox. If there was no way the past could be altered then how would Man A be Killer B and kill Woman C if Killer B could never go back into the past in the first place to kill the woman? By killing the woman inevitably changed the future which, according to this theory, cannot happen

Instead there are really only 2 different possiblities:

1. By going back into the past to change a certain event, something which cannot be countered prevents your from changing that even which will happen anyways no matter what you do.

or

2. By going back into the past to change a certain event, you succeed and create an alternate universe to support the event that you've changed. But im not a fan of multiple universes.

 

Either that or that stationary frame will be going really fast.

 

A paradox, or contradiction arises when two ideas each make the other impossible. Contradictions don't exist in reality because reality simply is as it is and does not contradict itself. Only our evaluations of reality can contradict each other. If you think you have found a contradiction, then check your premises. Either you're mistaken about it being a contradiction or one of the contradicting concepts has been improperly formed.

If the content of your knowledge contains contradictions, then some of your knowledge is in error. Because in order to be successful in reality one must know reality, success requires correct knowledge. It is therefore important to continually search for and root out contradictions in your knowledge in order to make sure that your knowledge corresponds to reality. The two primary methods for doing this are logic, the art of non-contradictory identification, and integration.

 

Im not arguing that it isn't a paradox. This whole thing started off because somebody tried to explain (in a wrong way IMO) how u couldn't go back in the past and change events. I tried to explain the real reason why u can't.
U have to remember Votorx that ur 1st possibility means that u cannot interact with the past because it is impossible to interact without changing the future.
