Physicist Creates Lab 'Mini Universe' to Investigate Whether Time Actually Exists
By
Ivan Farkas
Summary
This article explores the puzzling nature of time in quantum mechanics. It discusses how at the quantum scale, time as we know it doesn't seem to exist, and fundamental equations like the Wheeler-DeWitt equation suggest time may have no built-in direction or may disappear entirely at the deepest level. The piece contrasts this with the second law of thermodynamics and examines how a physicist created a "mini universe" in the lab to experimentally investigate whether time truly exists as a fundamental property of reality.

· 3 pulledThe quantum world is mind-bogglingly counterintuitive: at the smallest scales, basic physical qualities like position and speed are murky, and time as we know it doesn't seem to exist.
Fundamental mathematical rationale from Newtonian physics, quantum mechanics, relativity, and, more specifically, the Wheeler-DeWitt equation, suggests that time has no built-in direction, and may even disappear at the deepest level.
In contrast, the second law of thermodynamics...
