If gravity were to suddenly reverse, the immediate effect would be that we would all feel incredibly nauseated and start falling upwards, with other smallish objects. If we were outside we would quickly suffocate as we got further out, where the air is too thin to breath. If we were inside, we woupd find ourselves pinned to the ceiling. Very quickly after that, most buildings would start to fall apart, the reversed gravity literally pulling them out of the ground, and the dirt on the ground and the plants/trees would all fly up into the air. The oceans would spew their water all over the place. A little later, even reinforced earthquake-resistant structures would collapse, and the earth's crust would start to crack, sending chunks of rock flying around in the air. After that - depending on the speed of the reversal, anything from a couple of hours to many days - the crust would explode altogether, and the mantle would start to deform, bulging out and spreading as gravity pulled it away from the core. The liquid parts of the earth's interior would probably break through the mentle in places, squirting all over the place, abd eventually freezing and shattering. Then the core itself would be blown apart. In all likelyhood, this would trigger an enormous nuclear explosion, engulfing the remains of the earth. All the while, the sun has been going crazy, expanding a million tines faster than it was supposed to.A while after the earth's demise ,it would explode rather spectacularly, dousing the entire solar system in fire and radiation. The other stars across the galaxy would do similar things. Finally, the supermassive black hole which our galaxy is formed around would start spitting out random matter all over the place with increasing speed, essentially destroying itself. the remains of the star systems would drift apart, propelled by the feeble remains of the reversed gravity. Years later, the universe would settle out into a slightly radioactive soup, with a good few light years from one particle to the next.
Is it normal to wonder what would happen if gravity was reversed?

Sorry for any spelling mistakes. Hope this helps!
