... The quantum Zeno effect (QZE) is the suppression of transitions between quantum states by frequent measurements. It was first considered as a theoretical problem where the continuous observation of an unstable particle would prevent its decay [1]. Experimental demonstrations of the QZE [2 –8] have b ...

Presentism and Quantum Gravity

A scientific theory is taken to have two parts, the theoretical structure and the theoretical hypotheses. The theor ...
