How Come We’ve Never Observed a Black Hole Decaying?

A black hole, even in radio wavelengths alone, will exhibit a large number of different features owing to the bending of light by the curved space surrounding the black hole. Some of the material from behind the black hole, some of the material from in front of the black hole, and some photons from all around it will be bent and sent off along any particular line-of-sight.

All throughout the Universe, ranging from just a few times our Sun’s mass all the way up to supermassive scales, black holes are found almost everywhere.

According to Stephen Hawking and the concept of Hawking radiation, black holes cannot remain stable forever, but must inevitably decay.

And yet, across the entire Universe for all the time we’ve been observing it, we’ve never once seen a black hole actually decay.

There’s a scientific reason for why. Use the link below to read about it.
