I expect I am wasting my time. I expect the only people here are (1) people who already know this and (2) people who will never listen to this. The Life and Death of Stars map.gsfc.nasa.gov/universe/rel_stars.html "After a low mass star like the Sun exhausts the supply of hydrogen in its core, there is no longer any source of heat to support the core against gravity. Hydrogen burning continues in a shell around the core and the star evolves into a red giant. When the Sun becomes a red giant, its atmosphere will envelope the Earth and our planet will be consumed in a fiery death." www.youtube.com/watch?v=4xIQGbYur9Q Professor Dave Explains The Life and Death of Stars: White Dwarfs, Supernovae, Neutron Stars, and Black Holes Aug 24, 2018 We've learned how stars form, and we've gone over some different types of stars, like main sequence stars, red giants, and white dwarfs. But a star will move between these categories over its lifetime. How does that happen, exactly? And what is leftover when a star dies? A white dwarf? A neutron star? A black hole? What are these objects? Let's answer all of these questions and more by analyzing the life cycle of a few different star types!

22 billion years before the last light in the Universe goes out. Maybe then another big bang.

You get a much better understanding of life when you identify that, "You are a child of the Universe".

www.youtube.com/watch?v=0I33YxlQpvU Anton Petrov Earth May Survive Red Giant Sun After All, According to a New Study Jan 6, 2024 Hello and welcome! My name is Anton and in this video, we will talk about the future of planet Earth when the Sun becomes a red giantHow did planet Halla survive being swallowed up by its ageing star Baekdu?
28 Jun 2023 www.abc.net.au/news/science/2023-06-29/halla-planet-survivor-baekdu-star-red-giant-white-dwarf-merger-/102534242
Like the fictitious Star Wars planet Tatooine, the authors propose the real life Halla may have orbited two suns.
They think Baekdu could have formed through a collision and merger of a smaller white dwarf star and a larger red giant, which circled each other.
When the red giant swallowed the white dwarf, it triggered an early switch to burning helium, which would have shrunk the star.
"It changed the chemical make-up of the star and led to the star not becoming as large as it would have been," Dr Huber said.
Measurements by team member Ben Montet, from the University of New South Wales, shows there are much higher than expected amounts of lithium in Baekdu's surface, which supports this hypothesis, since lithium can be produced when stars merge.
Another more speculative explanation is that Halla is a new planet created by the merger of the two stars.
According to this idea, the collision between the two stars produced a cloud of gas that formed Halla, which would then be termed a "second-generation" planet.
Astrophysicist Rob Wittenmyer at University of Southern Queensland welcomed the research.
"The most exciting thing is always when we find something that should not be there," said Professor Wittenmyer, who was not involved in the research.
