minus-squareRevan343@lemmy.calinkfedilinkEnglisharrow-up9·2 hours agoOf course. It can’t travel faster

minus-squaredavidgro@lemmy.worldlinkfedilinkEnglisharrow-up1·18 minutes agoChanges in the gravitational field definitely travel, and do so at the speed of light. Look up LIGO
minus-squareAlk@sh.itjust.workslinkfedilinkEnglisharrow-up2·2 hours agoIf it didn’t travel, it wouldn’t take 8 minutes to stop right?
minus-squarecuerdo@lemmy.worldlinkfedilinkEnglisharrow-up1arrow-down2·2 hours agoIf the mass vanishes, then the gravity would also vanish, at the same time.
minus-squarechuckleslord@lemmy.worldlinkfedilinkEnglisharrow-up2·1 hour agoFalse. 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.

Yes. General relativity.
