I am having trouble understanding how the vector equation of a line : (x,y,z) + t(x1,y1,z1) can be used in conjuction with another vector in the form (x,y,z).
I visualise it like this. Points are : O to P and O to Q. So there are two vectors. The vector P to Q is given by Q - P which is the...
Faster than light (FTL) is not possible via entanglement because you need to compare both the photons...
or in other words
entanglement is a single system that is "spread out" (across time-space) , the two photon pair behaves as a single system in which
the two photons are within that system...
