  Changes in the gravitational field definitely travel, and do so at the speed of light.

  Look up LIGO

  If it didn’t travel, it wouldn’t take 8 minutes to stop right?

    If the mass vanishes, then the gravity would also vanish, at the same time.

      False. If the mass vanished via magic, the effect would ripple out at the speed of light. Source, gravity waves which move at the speed of light.

      But vanishing is magic, it goes against the laws of physics, so you could apply any fictional logic
