paradox

[Sammael]

do you belive its true

example of a paradox:

you go back in time and kill your grandfather (before he had offspring) could you because if you killed him he wouldnt of giveing brith to your father/mother which in trun didnt give brith to you which means you couldnt of killed him.

[shooty08]

perhaps you simply become the child of some other coupling and the man you killed is no longer your grandfather?

lol you heard of Gentics and DNA

[spoiler]Genetics , a discipline of biology, is the science of heredity and variation in living organisms. The fact that living things inherit traits from their parents has been used since prehistoric times to improve crop plants and animals through selective breeding. However, the modern science of genetics, which seeks to understand the process of inheritance, only began with the work of Gregor Mendel in the mid-nineteenth century.Although he did not know the physical basis for heredity, Mendel observed that organisms inherit traits in a discrete manner—these basic units of inheritance are now called genes.

Genes correspond to regions within DNA, a molecule composed of a chain of four different types of nucleotides—the sequence of these nucleotides is the genetic information organisms inherit. DNA naturally occurs in a double stranded form, with nucleotides on each strand complementary to each other. Each strand can act as a template for creating a new partner strand—this is the physical method for making copies of genes that can be inherited.

The sequence of nucleotides in a gene is translated by cells to produce a chain of amino acids, creating proteins—the order of amino acids in a protein corresponds to the order of nucleotides in the gene. This is known as the genetic code. The amino acids in a protein determine how it folds into a three-dimensional shape; this structure is, in turn, responsible for the protein's function. Proteins carry out almost all the functions needed for cells to live. A change to the DNA in a gene can change a protein's amino acids, changing its shape and function: this can have a dramatic effect in the cell and on the organism as a whole.

Although genetics plays a large role in the appearance and behavior of organisms, it is the combination of genetics with what an organism experiences that determines the ultimate outcome. For example, while genes play a role in determining a person's height, the nutrition and health that person experiences in childhood also have a large effect.[/spoiler]

Its impossable to born out of another set of DNA

I'm just suggesting that perhaps that would be the timeline's way of dealing with a paradox of that nature. either that, or you'd just be stuck in a loop of two timelines: one where you don't exist to come back and kill your grandfather, and one where you are born, go back and kill grandfather, only to make yourself cease to exist.

[Sammael]

maybe but as they say past is past you CANT cange what has already be done.

you go back and kill him then you wont be alive to do it will you so you couldnt go back and kill him.

but if tou go back in time and kill im ten you vansish say you just start to fade all you did in that time you were alive will be undone aswell so you might cause the whole timeline to back in time or have millions of peoples lives change in the matter of seconds babys that where born unborn then trere lives wouldnt of happened then the poeple tey ave thoched they change i say millions but billions of lives will chnage maybe the every living thing on this planets will change.

[shooty08]

well, once they invent time machines, would you do it and let us know the results?

Assuming Time travel were possible & what we currently hold to be the truth of the universe was also correct then;

When you travel back in time you are creating an alternate timeline, one the branches from the moment you travelled into the past. As of that point you essentially have no parents or grandparents so you could kill anyone you liked without worrying about suddenly disappearing.

Of course there are problems with this explanation, especially the idea that multiple timelines can exist in an infinite amount (i mean how the hell do we know?)

Best way of looking at it is to watch SG:Continuum & listen carefully to Sam's explanations to Daniel & Cam

[Deaths_Rider]

a paradox is impossible if only because before you traveled back in time to do whatever it is your doing it's already been done in the time your currently in. just becuase you haven't done it yet in "your" timeline in universal time it's already happened you cant change the past only fufill it so killing your own grandfather for instance was ment to happen how you end up being there who knows maybe he left a pregant wife or mistress or you were cloned

ok w8 since cam is jack o neils son because they went back in time and you know whats happens after that i wont explain the brids and bees to you guys say they didnt go back in time cam wouldnt be alive to be SG1 leader and all the missions might of hd differnt outcome in that timeline this will go in to dimentions in a minute.

so you say it impossable but te timelne you left or whent back in time you would cess to exiset so you wouldnt be able to kill him if you wernt alive in that timeline.

Only reason that worked was because they were in the stargate when the timeline changed, and thus they were insulated from it. Their current timeline counterparts were there, excluding cam because his maternal grandfather died before his mom was concieved, so there was no way for cam to have been born even if O'neill had been going on missions in the stargate program.

Basically, the mechanics of wormholes and time travel are twisted and **Filtered** up.

you missed my point completely the past has already happened you cant change it even with time travel so if you exsist to go back in time then you exsist despite what you do back there as whatever happens is the same timeline you left the idea of branching timelines and alternative futures is great for TV and movie writers but not for science

Basically, the mechanics of wormholes and time travel are twisted and **Filtered** up.

oh please tell me you base this on more than stargate and other scfi

They all say whats past is past but time travel at the current day is not around, but if it did and you went bck just you would still exsist in that time line but if you killed your grandfather you wouldnt would becuase as soon as you alter te timeline your in to effect you in this case so your granfather and granmoter dont reperduce you wouldnt exsist so you couldnt go back and kill him.

Again assuming our current theories are correct ;

When you time travel you are moving yourself from one timeline to another, you cease to exist in the timeline you travelled from and only exist in the timeline you've travelled to.

Therefore it is fully possible to then go and kill off your grandparents in this new timeline without repercussions because the people you know are your grandparents might not be the same in this timeline and also because in this timeline you have no grandparents or parents to worry about killing off.


btw, I only mentioned the SG-1 as each time they time travel in the series & the film Sam does a very good explanation that is a good dumbing down of our understanding of the science behind the idea of time travel (ie referenced only for the explanations and rationalisations rather than actual events in the film/series like the wormhole protecting them).

Of course we could be wholly wrong but until someone actually does time travel we'll never know.

Acording to the latest theory, reality exists in more than the 4 demensions we experience. We experience time linearly but it actually exists concurrently. SO this is essentially bang on. besides the whole it's impossible to go back in time thing.

Nice post.

I heard from somewhere that you can't go back in time as it would conflict with the laws of physics. Light can't be reversed but the change in direction can. So theoretically you can jump forward in time but you can't go back in time. You're stuck forever where you jump.
