    Recently there was a rumor spreading around my work that the earth was about to lose gravity for seven seconds and they should stay home to be safe.

      I do oft wonder about the Dzhanibekov effect, and what the inertial effects (direction/strength/duration/curves/etc) would be like at each location on the spinning object, and if Earth’s Large Low-Velocity Provinces (LLVPs) or Large Low Shear Velocity Provinces are sufficient tributary oscillation to trigger a flip as some interpretations of the evidence suggest has happened to earth before (most recent suggestion I heard, this may have happened 700,000 years ago, iirc ~ or was it 700 million… I forget), … and in that moment, would there be locations that experience an effective loss of local gravity for seconds?

      If such is going to happen (or just a magnetic flip, or a corona mass ejection, or a X100 flare, or a meteor bombardment, a rogue planet flyby perturbing orbits, or whatever other calamitous disruption to the pleasant habitability of Earth), to be safe, I think I’d rather have a spaceship to fly away instantly in, than stay home. (I guess humans should not have been industrially sabotaging and suppressing that arc of human made technological arc of innovation for a century or two.)

      No, no. It’s absolutely true.

      Scientists have known for years that the Earth’s gravitational field is remarkably stable, except when I fart.

      At precisely 8:47 PM, I unleashed a fart of such extraordinary magnitude that NASA immediately detected a gravitational anomaly.

      For exactly seven seconds, gravity simply gave up.

      Cars floated. Birds were suddenly extremely confused. Somewhere in Ohio, a man watched his refrigerator slowly drift toward the ceiling.

      NASA scrambled to identify the source.

      “Where is this coming from?”

      The technician checked the instruments.

      “Sir… Georgia.”

      A long silence followed.

      “Dear God.”

      At exactly seven seconds, gravity returned.

      Scientists are now studying the event.

      I have been asked not to fart again.

      I have declined to comment.
