Why does a star explode in a supernova?
Our sun will have burned up all the hydrogen in a few billion years. The hydrogen will have been converted into helium. The helium then also burns and this produces oxygen. Once this has also been burned, then, given the size of our sun, no further chemical conversion can take place and the sun's fire goes out. However, if the radiation pressure no longer exists from within, then the sun collapses under its own gravity. And then it explodes and hurls gas and dust into space, creating even more elements. But why does the sun explode? I understood the implosion due to gravity, but not the explosion. I know that there are theories according to which the sun is too low in mass to end up in a supernova. But a report on Phoenix last year contradicted this theory.

I think if even more massive stars, such as the sun or even the more common little red or orange dwarf stars, would end up as supernova, we would have much more frequent to consider a supernova in the sky. However, they are very rare, perhaps every 1000 years in a galaxy. I don’t believe in a supernova of the sun.
That’s not true. According to this report, 1-2 supernovae should take place in our Milky Way in 100 years. So the next one would be overdue.
I know, after calculations, even every 30 years, but the last known Supernova in the Milky Way was 1604, apart from a ́in the Magellan cloud about 20 years ago.
No type I
However, it must be borne in mind that large stars have a much shorter life expectancy than the sun. They are much more wasteful with their hydrogen supply and are practically the playboys under the stars that have a lot of supplies but consume quickly. The Beteigeuze has changed its diameter for a long time in an irregular rhythm, which is an indication of an upcoming supernovae.
Only I could imagine that the “end” of a star can also take a few milliönchen years for a lifetime of 10 billion years. And for so long the Lord will not want to give me my life.
This may be so far in the morning, a typical well-known candidate would be, for example, the red giant star Beteigeuze in the constellation Orion, which stands at the end of séine life.
Goddamn I hope for years to be able to experience this spectacle in my life
The implosion causes an internal pressure build-up, which results in an JoJo effect as expansion.
In the sun nothing burns, mergers take place. For a supernova the sun has too little mass. She will end as a white dwarf .
Because God is so WOLLTE!!!
