Stephen hawking hawking radiation
網頁2 天前 · In 1974, the brilliant physicist Stephen Hawking, who died in 2024, plunged the physics world into a crisis: he calculated that black holes destroy information. Hawking explained that radiation emanates from a black hole slowly and in the form of thermal energy -- so-called Hawking radiation. 網頁2024年7月1日 · Hawking eventually squared the two ideas in 1974, showing that black holes could have entropy and emit radiation over very long timescales if their quantum effects were taken into account. This phenomenon was dubbed “Hawking radiation” and remains one of the most fundamental revelations about black holes.

This is perhaps a difficult concept to grasp. Although empty space contains no mass, no particles or quanta of energy, the quantum fields which define them still exist in the vacuum of space. The usual explanation is that these fields, because they are ...
