Настоящая Симуляция Вселенной
Сейчас одни рассуждают о том, а не живём ли мы в симуляции, в то время как другие создают настоящие симуляции Вселенной. Правда, они отличаются от того, о чём фантазируют любители порассуждать о том, что мы живём в Матрице. В этом видео я расскажу о том, как и для чего учёные создают научные компьютерные симуляции Вселенной.Поддержать проект “Космос просто”:
