Black holes radiate so much, why does Hawking say that black holes are spitting out matter?
Note that light is also a radiation. In the initial stage of black hole formation, not much energy will be radiated, otherwise there will be no such terrible matter in the universe. Also, you misunderstood Hawking's words. The mass of a black hole is calculated according to the mass of the death star, that is, the size of the star will make the black hole bigger. Blue giant, like Centauri, is billions of times bigger than the sun. If it dies, the solar system will suffer, but the sun will be finished before it dies, with 5 billion years left. So don't worry at the moment.
The so-called smaller mass is actually a special case. Hubble telescope observed a very abnormal special case, that is, even the replaced gas was shrinking before the death of the star, and no red giant was produced. The material formed was very small, with great radiation and gravity. It can be confirmed that it is a black hole, and it has been observed many times since then, so the death of a star may not necessarily produce a red giant, but such a star is very dangerous.
Small diameter means that the radiation surface of the black hole is small and the space for energy gathering is small, which means that the energy gathered by the black hole is small, so we have to radiate our own energy to maintain the normal state, otherwise it is likely to explode because of too much energy. Of course, a piece of this substance can be released from the black hole twin brother on another time axis and space plane.
So the energy that a black hole can hold is directly proportional to its volume and the energy before the death of its star. But energy is conserved, just like Leonardo da Vinci's perpetual motion machine, it is impossible to move forever, because there is not much energy to support him to move forever. The extremes meet, remember this sentence.
