actually the marbles change colour every 1 second and you can take them really far apart, meaning one can go at a really high speed and distance trough universe, so the time would have dilated for it. when you open them both have same color

[andomar]

That sounds logical. Relativity theory allows you to age one object faster than another by changing their relative speed. Nobody would claim there was information travelling faster than light in your example.

What makes people say information travels faster than light with quantum entanglement?

If the marbles were changing colour at random but still alwasy different colours, that would suggest info is doing so.

[andomar]

If they change color in sync then that is a known property of both marbles. Say you have a marble that is blue if the number of seconds is even and red otherwise. Knowing the color of one marble is enough to know the color of the other marble without information travelling between the marbles?

[throwaway_pdp09]

Not my area. My understanding: colours sync exactly on measurement (when you look at them).

> Knowing the color of one marble is enough to know the color of the other marble

I guess so.

> without information travelling between the marbles?

The marble colours are in sync on measurement. Somehow that info has travelled instantaneously. You just can't use it to send information, at all..

above is just my understanding. I have no background in this. Just a programmer.

They don't.
