Behold what Hollywood thinks of as a hundred-million-dollar idea for a “science” fiction movie:

Scott Waugh Circles Sci-Fi ‘Inversion’

“Inversion,” unveiled at Cannes by Mark Damon’s Foresight Unlimited, follows a young Chinese scientist and a street-smart American expat in a race against the clock across the globe to save Earth from an apocalyptic threat — a reversal of gravity causing civilizations to uproot and plummet into the sky.

Wat.

Look. No. Gravity is not going to suddenly invert, not, at least, unless and until the “Phantom Energy” that seems to be a slight antigravitational force gains in strength *billions* of years from now and results in the Big Rip. If the idea  behind “Inversion” is that the Big Rip is happening *now,* there WILL BE NO RESCUE. Unless someone builds a doorway to another universe (paging Dr. Bishop), the Big Rip will be a universally unsurvivable event.

And if gravity is beginning to invert for *whatever* reason, you won’t have “civilizations” popping off the planet and shooting into space. You’ll have the *atmosphere* saying “see ya” right quick, and then the whole planet will slow-motion explode. Not in big chunks, most likely, but more like an evaporation that occurs all at once. And shortly after the planet tears itself to bits, spacecraft that might have gotten away will also shortly tear themselves to bits as the increasing antigravitational force  overcomes structural strength. Then the bodies of the astronauts will disassemble, then their cells, the molecules, the electrons will shoot away from the nuclei, the nuclei themselves will explode and then the particles will go foom.

And unless the movie is positing some sort of Doctor Doom/Lex Luthor type supervillain with a cartoonish “anti-gravity weapon”, you won;t have localized gravity reversals. it’ll be everywhere, all at once.

Arrrrgh.
