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

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.
