Энергия вакуума — энергия, связанная с пустым пространством. Однако энергия, содержащаяся в вакууме, не равна нулю, поскольку в квантовой теории пространство никогда не является полностью пустым. Частицы непрерывно появляются на свет на мгновение и затем исчезают в небытие.
Энтропия — мера беспорядка физической системы; неупорядоченные системы имеют высокую энтропию, а упорядоченные — низкую. Энтропию также можно рассматривать как число способов перестановок, составляющих систему частей (например, молекул) без изменения общих характеристик системы, таких как объем, температура или давление.
