Webb27 feb. 2024 · Hawking radiation, predicted by Stephen Hawking in the 1970s, will cause a black hole to lose gravitational energy — and thus mass. In effect, black holes are not eternal. They slowly evaporate. Hawking initially believed that even if a black hole fully evaporated, the information it had consumed would remain lost forever.
