Will the sun ever stop shining? originally appeared on Quora: the place to gain and share knowledge, empowering people to learn from others and better understand the world.
Answer by Viktor T. Toth, IT pro, part-time physicist, on Quora:
The sun will not stop shining for a very, very long time.
The Sun, along with the solar system, is approximately 4.5 billion years old. That is about one third the age of the entire Universe.
For the next several billion years, the Sun is going to get brighter. Perhaps paradoxically, this will eventually result in a loss of carbon dioxide in the Earth’s atmosphere, which is not good news; it will eventually lead to the death of plant life.
By 2.5–3 billion years from now, the surface temperature of the Earth will exceed the boiling point of water everywhere. The process continues; by about 4–5 billion years from now, the Earth will be in worse shape than Venus today, with most of the water gone, and the planet’s surface partially molten.
Eventually, the Sun will evolve into a red giant star, large enough to engulf the Earth. Its luminosity will be several thousand times its luminosity at present. Finally, with all its usable nuclear fuel exhausted and its outer layers ejected into space, the Sun’s core settles down into the final stage of its evolution as a white dwarf. Such a star no longer produces energy through nuclear fusion, but it contains tremendous amounts of stored heat, in a very small volume (most of the mass of the Sun will be confined to a volume not much larger than the Earth). As such, it will cool very, very slowly. It will take many more billions of years for it to cool from an initial temperature of hundreds of thousands of degrees to its present-day temperature and below. But in the end, the remnant of the Sun will slowly fade from sight, becoming a brown dwarf: a cooling, dead remnant of a star.

- Big Bang Cosmology: The Big Bang is still a theory, so why is everyone so certain of the age of the universe?
- Physics: How can the sun have gravitational pull on all the other planets if it’s not even solid?
- Time: Since scientists have discovered how to make a black hole. Does this mean they can now figure out a way to slow or even stop time?

Response by Viktor T. Toth(*************** ), IT pro, part-time physicist, on Quora:(********************* )(*********** )
The sun will not stop shining for a really, long time.
The
Sun, together with the planetary system, is around 4.5 billion years of ages. That has to do with one 3rd the age of the whole Universe.(*********** )
For the next numerous billion years, the Sun is going to get brighter. Maybe paradoxically, this will ultimately lead to a loss of co2 in the Earth’s environment, which is bad news; it will ultimately result in the death of plant life.
By 2.5– 3 billion years from now, the surface area temperature level of the Earth will go beyond the boiling point of water all over. The procedure continues; by about 4– 5 billion years from now, the Earth will remain in even worse shape than Venus today, with the majority of the water gone, and the world’s surface area partly molten.
(********************** )Ultimately, the Sun will progress into a red giant star, big enough to swallow up the Earth. Its luminosity will be numerous thousand times its luminosity at present. Lastly, with all its functional nuclear fuel tired and its external layers ejected into area, the Sun’s core settles into the last of its development as a white dwarf. Such a star no longer produces energy through nuclear blend, however it consists of incredible quantities of saved heat, in a really little volume (the majority of the mass of the Sun will be restricted to a volume very little bigger than the Earth). As such, it will cool really, really gradually. It will take much more billions of years for it to cool from a preliminary temperature level of numerous countless degrees to its contemporary temperature level and listed below. However in the end, the residue of the Sun will gradually fade from sight, ending up being a brown dwarf: a cooling, dead residue of a star.
This concern initially appeared on Quora – the location to get and share understanding, empowering individuals to gain from others and much better comprehend the world. You can follow Quora on Twitter, Facebook, and Google+ More concerns:
- Huge Bang Cosmology : The Huge Bang is still a theory, so why is everybody so specific of the age of deep space?
- Physics : How can the sun have gravitational pull on all the other worlds if it’s not even strong?
- Time : Given that researchers have actually found how to make a great void.
Does this mean they can now determine a method to slow or perhaps stop time?
