Some more about time travel and infinity

[Merdarion]

Let us asume that time travel would be possible (I am not saying that it isnt)

You travel back in time and kill your father, you wouldnt exist in the future right? But if you dont exist you cant travel back in time to kill you father, which makes you exist once more and makes you travel back once more and kill your father once more, and so on, and so on.

Otherwise you travel into future and find out how the football championship ended. You bet all your money on one team. This team has lost cause of one player of the enemy team. So you go back to the point you have left and kill this player, which causes that your team doesnt lose the championsship. But now when you travel into future your team has won so you dont kill the player after travelling back.

So any of those situations ends in a infinitive function, which would make the world stuck in an eternal loop, cause due the tinyness of those actions the whole thing has a tiny change each time it repeats and all things would just start over and over again from the same situation.

So those paradox you often hear of wont destroy the world but make it stuck.

another thought of infinity:

a artist draws a picture, but he somehow feels that something is missing so he draws him self drawing the pic. Again he is missing something so he draws him drawing a picture on which he draws a picture.

Or another one:

Lets assume that you have a screen with unlimited pixel (1/infinity would be the largeness of the pixel) and a camera with such preferences. Then you connect the camera to the screen so it shows  the pic on the camera and then point the camera at the screen. What would happen?

Yes it would. World has a limited stack size and this infinite recursion will end up erasing the data section. The world would segfault and we would all get linkdead

My solution (yeah i\'m enough crazy to have tried to solve them ) to your paradox:

About time:
Add dimension to time. The time is elapsing in all dimensions, but each time you travel, your distance to the starting point remains constant or increase. To be exact \"present\" is a sphere centered on the starting point. For example, someone built a machine able to move in our \"first time-dimension\"

Moving from A to B. - means defined part of the time-space. You can only be in the 0 points (it is the multi-dimensional present).

------------------------B
--------------------------0
----------------------------0
------------------------------0
--------------------------------0
----------------------------------0
------------------------------------A

Then if you modify things, B would be modified, and all things that would have happened after B will also be. But not A! Because A happened at the same time as B!

- : past
+ : modified past:
0 : present

--------------------------B++++++++++B\'
------------------------------------------0
--------------------------------------------0
----------------------------------------------0

You\'ll say: But what happens if someone success to create a time - travel machine that can travel through the first and second dimensions? Then the third one will kick in to make the traveller stay in the \"multi-dimensional present\" and so on...

The only thing i can\'t explain with this system is travels in future.

About artistic stuff.
Quite easy. The size of the sum of the pictures is not infinite so a final picture may exists. So the artist just has to solve the problem (as i said immediately above, solution exists, because size is finite - demonstration is left to the reader, and it\'s maybe the only thing that can get a serious explanation ):

X = T(X) where X is the picture, and T is the transform: add a mini X on X

[edit] Ouch my head - i hope i will share my pain with you

You are sounding like my brother 8O

[elscouta]

Does that mean my explanation are too obscures to be understood?

You should have forecast this when you posted this thread

[Kwip]

You would not be able to go back in time and kill your father if he is alive at a point after the poin you go back, does not matter what you do you will not be able too.

If someone changes something in the past it will have already been changed before he went back there.  You can not change the past.

[Edit] Remember this is just what I think; could be wrong, but you will have to do a good job to convince me of that [/Edit]

[elscouta]

Well, my point is that changing the past would create another future, but not your future.

[Merdarion]

Well a good point escalouta. No no it soesnt mean that your explanations are obscure, It just means that I (stupid 14 - year old) doesnt understand them
