"Time might be a mirage created by quantum physics, study suggests"
by Ben Turner

…"researchers turned to a theory called the Page & Wootters mechanism … proposed in 1983, the theory suggests time emerges for one object through its #quantumentanglement with another acting as a #clock. For an unentangled system, on the other hand, time doesn't exist, & the system perceives the #universe as frozen & unchanging"…
