From Max Wallis, Cardiff Centre for Astrobiology, Cardiff University
Michael Brooks’s suggestion that physicists now believe entanglement between particles exists everywhere, all the time, as exemplified by light photons travelling from a star, brings wry smiles to we wave physicists (27 March, p 32).
We are quite at home with light waves interacting with the atoms of the star, and bringing us evidence of those atoms. But entanglement physicists believe observation of that light affects all those atoms instantaneously. They are clearly in a tangle.
