A Physicist Creates a Miniature Universe in the Laboratory to Demonstrate that Time Can Emerge from Internal Disorder (opens in new tab)

The research, published in Physical Review Research by Professor Giovanni Barontini, managed to measure the passage of time without using any external clock, instead defining the parameter based on changes observed within a system of ultracold atoms. The experiment directly addresses a paradox posed by equations like the Wheeler-DeWitt equation, according to which, at the […]
