Yesterday, we noted that researchers demonstrated quantum effects in giant molecules, showing that the 2000 atom giants could be in two places at once.
Our physics color commentator Rob Sheldon offers some thoughts on why it matters:
The point of this experiment is to test the Copenhagen interpretation of QM that says: “Newtonian physics is for big objects, QM is for small ones.” The question, of course, is “how small is small?” Evidently 25000 Dalton molecules with 2000 atoms (H,C,F,Zn, & S) is still small.
One QM theory variation on Copenhagen called “Continuous Spontaneous Localization” says that classical Newtonian physics arises from QM if an object has many, many modes or states, and when all these states “decohere”, they reduce QM statistics to classical statistics. By measuring a hot stream of molecules with billions of states, this experiment may rule out CSL. If so, it would be the first time an interpretation of QM was actually invalidated, suggesting we have entered a new era of testing theories of the foundations of QM. Perhaps we can soon test the wild theories such as Everett’s Many Worlds interpretation.
