  • Without gravity it’s a sphere, or in free fall without air drag it’s a sphere (if it has sufficient surface tension anyway, which is what makes lava or molasses flow that way, in combination with its viscosity).

    But in a vacuum it will boil off until the vapor pressure is high enough to eliminate the vacuum. But then it’s not in a vacuum anymore.

    Really a fluid or liquid will always try to minimize its surface area while fighting gravity.

    It’s a definitions problem that a lot of people who think there aren’t “objective truths” in science.
