  You should find a new hobby like googling because it would tell you the sun will burn out in ~5 billion years

    Questions are a good thing and preferring to get answers from humans instead of machines is a good instinct. Less harshness and more humanity makes the fediverse a better place.

      The correct thing would have been to look it up and share the information with the fediverse, this is a basic fact question not a matter of opinion or discussion

      This is just pure laziness.

  The sun will turn into a red giant, then into a white dwarf surrounded by a planetary nebula. This will take billions of years. The white dwarf is basically the ash of a star. It’s a glowing remnant that no longer has nuclear fusion and so it’ll just glow for trillions of years until it becomes a cold lump of carbon. The inner solar system will most likely be wiped out during the red giant phase as the sun will expand tremendously in size eventually reaching somewhere between earth and mars’ orbit.

    Fun fact, while the earth will almost certainly be engulfed by the red giant phase of our sun, it will not be immediately consumed. A floating lump of rock will exist and continue to orbit the center of mass for millions of years inside the sun.

      Couple problems with your theory. First, the roche limit will turn the earth into a rubble pile and/or ring system long before the earth is engulfed so it won’t be one piece when it is consumed. Second the surface and outer layers of the sun are plenty hot enough to melt rock and as soon as that happens the rock is probably just going to become part of the plasma making up the sun’s atmosphere.

  Of course, the sun isn’t special. We have about 5 million more years.

    Oh nooooo I’m not prepared please no

      With humans barely reacting to climate change, it will be quite a comedy when the sun starts expanding.

      This is fine

  You might want to sit down for this, but the sun is also a star. We’re just really really close to it.

    Yes, I know.

  One proposal suggests that the universe will entirely run down eventually. In many billions of years It will become a cold empty featureless vacuum.

    Billions? No. Try a googol (10¹⁰⁰) or more years. The most massive galactic black holes will take at least that long to evaporate.

  Yes, but humanity likely won’t be around to see it. It’s a ways off.

    No life on earth will be around to see it. All oceans will have dried up long before then.

  Yes, the sun will burn out next week, actually. Brijg a coat.

  our sun has already kaboomed once, that’s why we have heavy elements that are only made in nova

  source

  • MentalEdge@sopuli.xyz ⁨3⁩ ⁨weeks⁩ ago

    That’s not quite right. Our sun has never gone nova, and is a fairly young main sequence star. It’s still in the first “main sequence” of fusion after accumulating from scattered matter. It’s heavy enough to do fusion, but not heavy enough to really “properly” go boom at the end.

    While novas form heavy elements, the originating star either becomes a neutron star or black hole. Sol, our sun, is a a “normal” star which means it won’t properly go nova. It’ll just “burn out” and become a white dwarf.

    The matter ejected by a Nova flies out into the universe and falls in the gravity wells of other Solar systems. So our heavy elements likely hail from millions of other past stars.

    Those are from the progenitor stars that formed the nebula that our sun formed from. Our star has never gone nova and never will.

  Yes, obviously the Sun will burn out too. But you have a few billion years of time before that.
