The end of the Earth will probably come way before that. The Sun will get hotter and hotter for a while, and in about half a billion, or perhaps a billion years, it will get so hot that no life will be able to survive on Earth.

NO. Another viewpoint: It probably will be the end of the Earth as we know it. It's likely that the Sun will expand until the Earth is inside it.
It will end Its life as a white dwarf

The Sun will eventually end up as a white dwarf, a dense, Earth-sized remnant of a star. This will happen after it exhausts its nuclear fuel and sheds its outer layers into space, forming a planetary nebula.
A black dwarf is a theoretical end-stage of a white dwarf star in the far future, after it has cooled down and no longer emits light. White dwarfs are hot, dense remnants of low to medium mass stars at the end of their evolution.
Before a white dwarf, a star would undergo the red giant phase. After a white dwarf, a star may end its life cycle as a black dwarf, although no black dwarfs are currently known to exist in the universe due to the long timescales required for a white dwarf to cool down.
No. It will become a white dwarf in about 7.5 billion years time.
A white dwarf star starts out like a our sun and turns into a white dwarf at the end of the stars life cycle. They have used up all their nuclear energy. At the end of this nuclear burning stage the star expels most to all of its outer materials. This creates what is known as a planetary nebula. The hot core is the only part of the star that remains. Temperatures of the core can and will exceed 100,000 Celsius becoming a very hot white. From this point the star starts to cool down, but that takes a billion years or more.

No, the sun will eventually evolve into a red giant before shedding its outer layers and becoming a white dwarf. The white dwarf stage marks the end of its evolution, where it will slowly cool down over billions of years.
