Universe expansion: dark matter’s out, anti-gravity’s in, matter and antimatter still can’t get along

Dark matter, we barely knew you, but before we ever discovered in case you were, in point of fact, the invisible hand pushing the cosmos apart, an Italian scientist ginned up a brand new theory that has anti-gravity doing the Yoko Ono to the universe’s merry band of galaxies. Massimo Villata’s theory assumes that both matter and antimatter have positive mass and effort density, which gets particles attracting particles and antiparticles attracting antiparticles during the force of gravity. To offer dark matter the heave-ho from the galactic expansion equation, Villata supposes that the concept of general relativity applies in reverse to antimatter particles to create anti-gravity. And just as gravity pulls particles together, anti-gravity shoves them apart — giving the universe its burgeoning waistline, no clown , king , or colonel required.
