sir is this possible that a rotating object can create gravity??


The rotation of an object can affect gravity, such as through the frame dragging effect, but mainly gravity is a result of an object’s mass.


It occurs to me that the thicker atmosphere of these “super-earths” might also sufficiently obscure starlight to diminish the possibility that such beings would even develop a science of astronomy.

There’s probably a good SF story waiting to be written with that as a hook. Too bad I’m not an Asimov or Heinlein…
