Stellar nuclear fusion This may be the first super energy since the formation of cosmic matter atoms. Well, only possible, because it may be earlier, which I will mention later.
How big is the energy of stellar nuclear fusion? Let me tell you: the nearest star, the sun, about 4 million tons of matter are converted into energy in nuclear fusion every second. Is there no concept of converting 4 million tons of matter into energy? I don't want to use the hydrogen bomb as a weak weapon to describe it. It is equivalent to the energy released by the complete annihilation of 2 million tons of antimatter and 2 million tons of ordinary matter ... If you still can't understand me, then there is nothing I can do. ...

Helium flash is like a solar-mass star burning hydrogen in the core at the end, and the temperature is not enough to ignite helium nuclear fusion, which causes the core to collapse inward under the action of gravity and enter the degenerate state of electrons. As the core shrinks, the temperature rises sharply, and finally helium is ignited. However, due to the increase in temperature, the thermal expansion of degenerate matter is obvious, the temperature continues to rise, more helium is ignited, and eventually the sun will fuse most of the helium in a few seconds ... Think about it.
Type Ia supernova explosion When the nuclear fusion of a star with solar mass stops entering the white dwarf stage and there is a star with similar mass next to it, the white dwarf rapidly increases its mass by accreting the gas of the star. When its own mass increases to about 1.44 times the mass of the sun, it will break through the Chandraseka limit and a supernova explosion will occur in the carbon-oxygen nuclear fusion where the core heat is out of control. How fierce is this? Well, you can still see it tens of billions of light years away ... This is the standard candlelight used by scientists to correct the distance between distant galaxies (this is how the accelerated expansion of the universe was discovered), because its mass is constant (the limit of Chandraseka is about 1.44 times the mass of the sun) and the degree of explosion is the same-all explosions. So theoretically their absolute luminosity is the same.

Supernova explosion of massive stars
According to the current theory, the maximum mass of a star can reach more than 200 times that of the sun. Because of their huge mass, these stars burn very fast to resist gravitational collapse. When nuclear fusion reaches iron, because the energy required for nuclear fusion of iron element is greater than the energy released after nuclear fusion, iron nuclear fusion is a process of absorbing energy, so it can't continue, and the star collapses inward quickly under the action of gravity. And hit the core of the degenerated iron core and bounced back to produce a supernova explosion. After a supernova of this mass explodes, the core will collapse into a black hole, and the blown matter will become the source of our life. ...
The energy of black hole jet is very unknown. According to the mass of black holes and the velocity of accretion matter, the most violent black hole jet in the universe may be quasars. The terrible thing about this kind of energy is that it is not large, but concentrated, and it will be sprayed in one direction like a laser. The first black hole photo released in April this year shows that the black hole in the center of M87 galaxy has such a jet, and the visible part of the jet is as long as 4,000 light years, which is still very concentrated. And it is visible because it collides with interstellar dust and gas in high-speed motion. How powerful is this energy? Take a real Hubble photo and feel it.

Double black holes combined with gravitational waves
At the beginning of 20 16, LIGO laser interference gravitational wave observatory announced the first gravitational wave event detected by human beings. A black hole with 36 times the mass of the sun and a black hole with 29 times the mass of the sun are merged into a black hole with 62 times the mass of the sun, and three gravitational waves with the mass of the sun are released at the moment of merger. Wait, you may not feel anything. Let me put it another way: at the moment of merging, the three solar masses are transformed into pure energy and released in the form of gravitational waves, that is, antimatter with 1.5 times the mass of the sun and ordinary matter with 1.5 times the mass of the sun are annihilated at the moment of merging. ...
Double black hole gravitational wave
Although the supernova explosion mentioned above exploded, it was not completely converted into pure energy. Otherwise, there wouldn't be our star slag, and gravitational waves wouldn't have any pure energy of slag ... and these are just two small and medium-sized star-level black holes. ...
This is the slag of the black hole in the center of the galaxy ... and what happens when two black holes merge when galaxies merge? I'm excited to think about it. . . . . So some people say that the combination of gravitational waves and double black holes is the strongest super energy since BIGBANG! ! !
Enjoy the future merger of Andromeda and the Milky Way. In about 7 billion years, the central black holes of the two galaxies will merge.
