    Default If We Saw A Black Dwarf, What Would It Look Like?



    Just curious what the current scientific consensus is on that.

    I am not sure what you mean by a black dwarf. The universe isn't old enough for any stars to have gone cold yet. Perhaps you mean an orphan planet? Perhaps you mean a black hole?

    A black dwarf is a hypothetical construct of what the ultimate fate of a star might be. If you could live a few billion years more, and were in the vicinity of one, I suppose it would look something like Harry Potter wearing his cloak of invisibility. But I guess we'll never know!

    You could probably see one if you had a very strong flashlight so it would be easier to see than Harry Potter's invisibility cloak. But the main means of detection would be by 'feeling' the gravitational pull.

    Are you saying that if and when Black Dwarfs exist they would be invisible?

    By black dwarf, I mean the stage that comes after white dwarf.

    A black cat only spherical. Minus claws, eyes, whiskers, etc.

    Black means black in this case. No inner source of energy so it would only be visible by feeble reflection of incident light or by blocking out a light source behind it.

    It would be opaque and not very reflective.

    What would a black dwarf be made out of?
