    Anti-gravity: impossible based on known physics. Artificial gravity: doable, just make it spin.

      “Gravity is a mysterious phenomenon that we’re only beginning to understand and will likely never master, baked into the very fabric of the universe. But we can almost perfectly stimulate it by spinning real fast :)” will never not be funny to me.

      Spinning is definitely a close cousin to gravity but objects in a spinning reference frame don’t fall straight down. Whereas water poured on earth will fall straight down towards the gravitational center, water in a spinning gravitational reference frame will arc. So, definitely close, but not a one to one approximation.
