Rethinking of Einstein's Photon Box

Abstract

In 1930, Einstein proposed the Gedankenexperiment that seems to show the invalidity of the time-energy uncertainty relation. Bohr gave an answer to this Einstein's challenge by resorting to the Einstein's general theory of relativity. However, many scientists and philosophers have critiqued his answer, and proposed new ones. The important proposals in these are ones given by Treder and Busch. In this paper, I survey and critique these answers. The point is how to interpret the time-energy uncertainty relation appeared in the Einstein's Photon Box. Next, I suggest a new answer to the Photon Box Gedankenexperment. My suggestion is that measurement of energy of phton is done by measuring the mass of box before and after the emission of photon.
