First, take a black hole. One possible resolution of this “black hole information paradox” can be found within the radiation that black holes emit from their event horizons. Hawking radiation, predicted by Stephen Hawking in the 1970s, will cause a black hole to lose gravitational energy — and thus mass. The black hole information paradox asks what happens to the information that gets tossed into a black hole. After that point, however, the black hole starts to reveal its information in its Hawking radiation.
