So I watched this video talking about now slices, and how it seems that across vast distances of space, movement can affect what is actually the now of places far away. https://www.youtube.com/watch?v= This seems to be in direct conflict with what I've heard about quantum entanglement. Let's say we move an entangled particle across such a distance. If we start moving away with our particle at very fast pace, the entangled particle on the other side will be affected in the past, where as if we start moving towards it, it will be affected in the future. But from what I've heard, entangled particles change "simultaneously" without regard to which "now slice" is happening. Am I describing this correctly? Is anybody researching how these two phenomenon relate?
