Will the planet earth be destroyed before the supernova explosion or after the supernova explosion?

As you know, the evolution of every star from Hayil Govich to star formation and star birth, which is formed by electrons, protons and neutrons, and due to the interactions of these electrons, protons and neutrons inside the Goviches after 2 Millions of years and heating and turning into stars inside the nebulae of galactic clusters lead to the birth of stars inside the galaxies and nebulae. Now, after it turns into a star, at first they have a faint blue light that can be identified by powerful telescopes. And he recorded it under our name or in English, according to Russell's theory and Russell's curve, which says that at first the light of the stars is pale blue, and after a while it turns white, and after a period of time that will last millions of years. in yellow; that our sun is now yellow in color, that now about 4 billion and 600 million years have passed from the life of our sun and after that it turns orange and finally at the end of the life of the sun or star it turns red and the reason for the color The red color of these stars is due to the abundance of Alium gas in the star. Because the color of helium gas is red and because it has the property of escaping and opening, the star becomes bigger and bigger like a balloon and becomes a red giant or a new cloud. Of course, according to Einstein's theory, whose representative formula is E = MC2, which shows that the energy of the sun or star, according to quantum physics, inside the sun is hydrogen energy inside the sun. That is, 4 hydrogen molecules are converted into 2 or 1 helium molecules, and according to quantum physics, plasma physics or solar plasma physics, which some countries now want to use to produce electricity, not nuclear reactors, which are also less dangerous. They also produce more energy like the sun. And the property of hydrogen to helium is very high, and according to astronomers, the life of our sun is 10 billion years, and now it is almost half, and now it will end after 10 billion years, and the life of our sun will also end and turn into a cloud. The new star or giant becomes red. At this stage, the gravity of the sun or star increases, and according to astronomers, the gravity of the supernova increases so much that it can swallow all the planets of the solar system. And if it has escaped from the sun's gravity until then, after some time the sun or the star will turn into a supernova explosion, which is the explosion of the supernova and the transformation of that big star into a white dwarf, the gravity of the white dwarf is so great that even the surrounding light It devours itself and creates black holes, at which time no planet around it is safe (according to the theory of gravity) and this powerful energy of black holes will continue until the energy of white dwarfs and molecular collapse. which happens at a speed of 300,000 kilometers per second, and if two white dwarfs are trapped in a black hole, they will be more powerful. Of course, the white dwarfs themselves turn into black and brown dwarfs after some time and disappear in space. Now, how long will the life of the world and its creatures continue? Will these climate changes destroy the life of its creatures? Or that the planet Earth will continue to exist before the supernova explosion?

Astrophysicist here, I see a few things wrong with the theories in this post. However the most important is the thesis statement about the Sun going supernova, which is incorrect. The Sun does not have enough mass to create Iron in the core so it will not undergo the process of core collapse generating a supernova. It will however most likely eject the hydrogen envelope and leave a white dwarf star. Unless there is another source of mass to add onto the white dwarf, ie from a companion which our Sun does not have, the star will slowly cool and not produce a nova or supernova.

The Earth, will have most likely been consumed during the Red Giant phase of our star where the size of the star will likely extend beyond the Earth's orbit.

Emeritus Professor of Astronomy here. As noted by Mr. (Dr.?) Taylor , the Sun will never supernova. Also, when it becomes a red giant star, although its size increases, its gravity does not (gravity only depends on the mass of an object, not how big it is); in fact, red giants usually lose some of their mass as they expand, because the gravity at their surface is much less than when they are smaller, making Coronal Mass Ejections more frequent and of much greater mass; and as the Sun loses some of its mass its gravity will actually decrease, allowing the planets to drift a little away from it. When it expands to become a red giant it will definitely envelop Mercury and Venus and vaporize them, and as noted by Taylor, will definitely get larger than our present orbit; but whether it will vaporize the Earth depends on how much (or little) mass it loses as it expands. If it doesn't lose much mass it will also envelop and vaporize the Earth, but if it loses enough mass the Earth will move far enough away from its present orbit to simply melt, hen re-solidify after the Sun collapses to become a white dwarf. However, as the Sun ages it becomes about 5% brighter per billion years, and long before it is a red giant the Earth will be so hot that all life on Earth will cease to exist. So we actually have only about 3 to 4 billion years before the Earth is completely uninhabitable, even though the Sun should actually last about 12 billion years, so that it won't become a red giant until about 7 billion years from now.

Ignoring the fate of the Earth, Mars and all the planets beyond it will drift a little further away, but will still exist, and if there are intelligent beings (probably not descendants of ours, but there is no reason to think that our species is unique or of any importance in the Universal scheme of things) that can move to other planets or their moons when the Earth becomes uninhabitable, they would probably be able to survive the death of the Sun in one of a dozen or more ways. However, the question of the long-term survival of intelligent species is a topic unrelated to astronomy.
