A prominent physicist has dismissed the pursuit of immortality by tech billionaires as futile, arguing that their extreme measures—including experimental plasma transfusions—offer no scientific basis for defying time. While ordinary individuals turn to unproven methods like peptides and cold therapy to slow aging, the ultra-wealthy are investing in increasingly radical interventions with no proven success. The skepticism comes as part of a forthcoming lecture series addressing one of physics’ deepest mysteries: the fundamental nature of time’s direction. Experts question whether human ingenuity can ever reverse or control the irreversible flow of time.
