Is Death the End? Experiments Suggest You Create Time

When I was young, I stayed at my neighbor's house. They had a grandfather clock. Between the tick and the tock of the pendulum, I lay awake thinking about the perverse nature of time. Mr. O'Donnell is gone now. His wife Barbara, now in her nineties, greets me with her cane when I go back to visit.

We watch our loved ones age and die, and we assume that an external entity called time is responsible for the crime. But experiments increasingly cast doubt on the existence of time as we know it. In fact, the reality of time has long been questioned by philosophers and physicists. When we speak of time, we're usually referring to change. But change isn't the same thing as time.
