Что в вакууме упадет быстрее – тяжелый шар для боулинга или легкие перья?
Популяризатор науки Брайан Кокс (Brian Cox) провел для школьников эксперимент в самой большой вакуумной камере в мире, которую NASA использует для проверки космических кораблей в условиях приближенных к реальным. Камера содержит около 30 тонн воздуха, для откачки которого требуется целых 3 часа, после чего внутри остается всего 2 грамма воздуха и условия можно считать практически приближенными к идеальным.
