In conclusion, we have demonstrated quantum entanglement between two photons that do not share coexistence. Although one photon is measured even before the other is created, full quantum correlations were observed by measuring the density matrix of the two photons, conditioned on the result of the projecting measurement.A demonstration of retrocausation (retrodependency).@philipthrift
Very interesting, does it mean that everything is connected not only spatially but also temporarily?
@Philip Thrift
Retrocausation? So, I'm thirsty because I will drink water? This is to much for me :/

Sort of. The Wheeler delayed choice experiment indicates there is a time aspect to entanglement as well. Look that up on Wikipedia, and it is a bit odd. Quantum states and their entanglements are not something that exist in space or time, but which may have a representation in such. Things get a little odd with time because there is no such thing as a universal time operator. If there were it would mean the conjugate of time, which is energy, as an operator can't have a discrete spectrum.@Philip Thrift

Huw Price and Wharton have been beating this dead horse for a long time. Not many physicists take this seriously, for it would mean there is an underlying causal mechanism that would obey Bell inequalities. The Bell theorem illustrate how quantum physics violates these. The retrocauality idea is very much an auslander conjecture that not many take seriously.LCThis topic has been discussed for about 20 years here, beginning in the original group.

@philipthrift
NO!! That violates Bell's inequalities and this measurement was done with the stats that violate Bell's inequalities.

By 'here' I meant on atvoid and atvoid-2 (the sequel), not everything-list.
But the point is this topic was discussed for 20 years, beginning in the group started by Victor Stenger (Timeless Reality). Physics does not rule backward (or downward, for that matter) causation in or out, and someone who tells you absolutely it is ruled out has no understanding of physics.
Some are a dense today about this as they were 20 years ago. Don't buy into the fundamentalist cult catechism (and a total misunderstanding of physics) expressed above.

In general it is ruled out by definition, as in classical mechanics: The past and future are all determined by any sufficient set of conditions, so when we give past conditions we say they cause the future condition and when we give the future condition we say it is caused by the past.
