    Such a weird mentality. Why would being small make us any less significant than something large? Why would being large make us any more significant than something small? Silly.

    “Look again at that dot. That’s here. That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every “superstar,” every “supreme leader,” every saint and sinner in the history of our species lived there-on a mote of dust suspended in a sunbeam.

    The Earth is a very small stage in a vast cosmic arena. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot.

    Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves.

    The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand.

    It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we’ve ever known.”

    ― Carl Sagan, Pale Blue Dot: A Vision of the Human Future in Space

    I sure love living in a burning planet where I have to pay taxes to pedophiles who want to send me to a concentration camp.

    It’s all relative though. Yes, we’re insignificant to the rest of the universe, but…

      You can’t get to this star in Elite Dangerous, but you can get to VY Canis Majoris which is 1420 radii

      what is the minimum and maximum size of a star? i.e. what is the minimum mass to ignite hydrogen fusion or whatever generates heat, and what is the maximum size where it just collapses into a black hole?

        The minimum is about 80 Jupiter Masses. Smaller than that and you can’t start fusing.

        Maximum size is harder to answer. It’s determined by the Eddington Limit. Which describes the luminosity at which radiation pressure is enough to overcome gravity for a certain mass.

        It’s thought that the maximum mass of a star is somewhere around 150 solar masses, but there’s some evidence to contradict this, as we’ve seen a handful of very old stars with masses or luminosities higher than they should be.

    And yet we are the only conscious beings on any of these heavenly bodies that are aware enough to give their existence any meaning at all.

      Dwarf planets: Pluto, Haumea, Makemake, Eris

      There should also be one (Ceres) in Jupiters shadow, right of the planet the arrow is pointing to. Which is Mars and not earth btw …
