报告摘要：Measurements have a special role in quantum theory, affecting the state of the system. The measurement problem refers to the difficulties in properly understanding how an event -that is, a measurement producing an outcome- can be defined within unitary quantum theory, without ad-hoc assumptions. In this talk I will present one possible solution, that rests on assuming that the Universe imposes fundamental uncertainties on the precision with which time can be measured.
