John Moffat and I now have a bet.
Perhaps in the not too distant future, quantum entanglement will be testable over greater distances, possibly involving spacecraft. Good.
Now John believes that these tests will eventually show that entanglement will be attenuated at greater distances. This would mean, in my mind, that entanglement involves the transmission of a real, physical (albeit superluminal) signal from one of the entangled particles to the other.
I disagreed rather strongly; if such attenuation were observed, it’d certainly turn whatever little I think I understand about quantum theory upside down.
Just to be clear, it’s not something John feels too strongly about, so we didn’t bet a great deal of money. John recently bet a great deal more on the non-existence of the Higgs boson. No, not with me… on that subject, we are in complete agreement, as I also do not believe that the Higgs boson exists.
