As i see it you cant add or sum corect in reltivity with out many worlds
I don't think any of the many worlds hypotheses have anything much to do with relativity. Can you explain what you mean?Originally Posted by Water Nosfim
Try to add and youll do same mistike ,you have to seperad it to many world to avoid problem
Would you care to explain this further ? I associate "many worlds" with a certain interpretation of quantum mechanics; it doesn't have anything to do with relativity.
If you add time in one place as you see it from the secend is that you decres and thats from one point of vieu is to go back in time and that alowd in many world interpetion
I don't understand what you are saying. Time ( I presume you are referring to proper time ) never "decreases". Time can be seen to run faster or slower depending on the observer, but it never runs backward.
To add in one direction is to decrease in the secend
Not really. Time goes forward for everyone. It goes faster or slower (relative to someone else) depending on relative velocity. This does not allow any to travel or communicate "backwards" in time.
No it is not. Like Strange and myself already mentioned, time always runs forward for all observers.
Comper , reltiv direction
That has nothing to do with the direction of time. Time always runs forward, for all observers.
I'm sorry, you really need to improve your English. I can usually extract a bit of meaning but I have no idea at all what that means.
The only time that any sort of communication backwards in time could happen (hypothetically) is if it were possible to communicate faster than light. As far as we know this is impossible.
Are you think of something like the Twin "Paradox" (which isn't a paradox at all).
If you look long from the secend direction you look sort if you look fat from the secend direction you look thin , if you look going forwerd from the secend dirction you look backwerd
Sorry if i do mistake in english from ater dirction you write corect
You canot add time from boteh direction if its not liner
It is linear, that is what we are saying. It runs in only one direction, and cannot double backwards into itself ( closed time-like curves aside for the minute ).
Perhaps you could provide a specific mathematical or numerical example where you think it doesn't add linearly.
point A , time + dalta = present , point B = present - dalta , its not nice matamatic but point B = present - dalta , samething like that ?
Are A and B in relative motion?
How do you get "present - delta"? Time can only increase so I don't know what that is supposed to mean.
When you use words like "time" and "present" and "delta" you need to say whose frame of reference you are talking about. The time,*delta and present as measured by A are different from those measured by B (assuming they are in relative motion).
I get the impression you don't really understand how special relativity works. Is that correct?
bud exsampel its jast dont add from both direction
So come up with a good example or admit that you don't really have a case. Presumably because you don't understand SR.
Do you understand special relativity and how the Lorentz transform is used?
different measured different present , you canot add
You can, when you take the effects of realtive velocity into account using the Lorentz transform. Do you know how to do this or do you need us to explain?
when you look at the frame from both direction you get contridiction , i cant be more simple then that , you have to use many world and there disapiring to get back to one frame
There are no contradictions in the theory of relativity, you just have to be clear about what type of reference frame you are dealing with, and use the correct transformations.
Are you confused because if we have two people, A and B, moving relative to one another then A will see B's clock running slower and B will see A's clock running slower.
This is purely an effect of both velocity and time being relative and dependent on who measures it. No "many worlds" needed.
if two people see difrent thing or thay laying or in difrant world , when thay retern together the sum of the time should be the same ? ? ?
Two men are standing next to each other but facing in opposite directions. Man 1 says that he he leftmost and that Man 2 is rightmost. Man 2 disagrees, He say that he is leftmost and Man 2 is right most. Are one or both lying? Are they in different worlds? No, to both. Relativity is something like that. People with different velocities can disagree as to who's clock is running slower just like people facing in different directions can disagree as to who is to the right or left, without either of them lying or having to be in different worlds.
take 2 men seprate them fast and get them back togeter fast , whos clock will run what ?
It depends.
Firstly, two people moving relative to one another will both observe the other's clock running slower. This is like perspective: both will see the other getting smaller as they get further apart.
In your example, you are now introducing acceleration (speeding up, slowing down, turning); this may break the symmetry. If the two of them both accelerate away from earth and turn round and come back at the same speed then, when they come back together both will agree about the time. If one stays on earth and the other accelerates away and then turns around and comes back, then his clock will have passed less time (he will be younger) than the one who did not accelerate.
Twin paradox - Wikipedia, the free encyclopedia
only 2 men , free exsample ?
That was only two men. I know English is not your first language so let's try again.
Two men: Mr. A and Mr. B. They are exactly the same age.
Three examples.
Example 1:
Mr A and Mr B are travelling at a constant velocity relative to one another.
Mr A will see Mr B's clock running slower than his.
Mr B will see Mr A's clock running slower than his.
After some time, Mr A will see Mr B as younger than him.
After some time, Mr B will see Mr A as younger than him.
(There are some slight complications due to the Doppler effect if they are moving towards each other or apart.)
This is similar to perspective: Mr A will see Mr B as smaller than him; Mr B will see Mr A as smaller than him. Perceptions of space, time and energy are dependent on who measures them.
Example 2:
Mr A and Mr B both accelerate away from each other and then turn around and come back to the starting point.
When they meet they will both have passed the same amount of time; there clocks will read the same time.
Example 3:
Mr A stays where he is.
Mr B accelerates away then turns around and comes back to Mr A.
When they meet Mr B has experienced less time than Mr A.
Mr B will be younger than Mr A.
Mr B's clock will have passed less time than Mr A's clock.
OK?
Lets coose exsampel 2 what hapend when thay slow down , whos clock will run what?
And if you disaze how to add,in any case what ever , tell the same qestion when thay start 2 meter apert , when thay start to move one to enater ? Same where ill will gets you
One qestion 3 difrent anser , am i lying ?
But when thay slow down thay aproth 0 speed and agine sameting is fleeping , no way , sameting lying or in difrant world
Spesl balony , reltiv balony , balony , balony , same time , the time can go backward , and what ever
I'll take that as a statement that you prefer to remain ignorant, rather than learn. That is fine with me. Although a little sad.
To be honest, your english is so bad I can't tell at all what you are talking about. I commend the efforts of those who have tried to figure it out, but even they might have misintepreted it.
If you want to be understood, I'd strongly suggest you put more effort into something resembling proper english, so we can all participate. I know English is hard when it's not your first language, but man, you're not even close.
Just a suggestion.

Once again, time never goes backward for any observer. Clocks can slow down relative to each other, they can even stop ( in principle ), but they never run backwards.
time doesn't run backwards, it's just like sending the signal(or you're moving) so fast, that you would have passed the point of the signal.
i don't know if that example can be used. like:
2 ppl threwing a ball back and front to each other. if on of them is faster than light, he would catch the ball before you threw it. because he passed the point already.
Because thay moved it i just want the link and how its end - From who's perspective do we measure Lorentz Contraction?
