We can understand quantum entanglement if particles in our 3-dimensional space are actually strings in a 4-dimensional space.
One of the most counterintuitive aspects of quantum mechanics is entanglement: We have seen in experiments that there are correlations between events that are far away from each other – so far, in fact, that no signal or anything else can travel from one to the other to cause the correlation. Words cannot express how bizarre this is (although Einstein came a long way when he called this “spooky action at a distance”)*.
But what if the universe has four spatial dimensions of which we are aware of only three? Could points in space we think of as far away from each other actually be connected through some invisible, higher dimension?
