Universe enlargement: darkish power’s out, anti-gravity’s in, matter and antimatter nonetheless cannot get alongside
Darkish power, we barely knew you, however earlier than we ever came upon when you have been, in reality, the invisible hand pushing the cosmos aside, an Italian scientist ginned up a brand new concept that has anti-gravity doing the Yoko Ono to the universe’s merry band of galaxies. Massimo Villata’s principle assumes that each matter and antimatter have constructive mass and power density, which will get particles attracting particles and antiparticles attracting antiparticles by way of the drive of gravity. To offer darkish matter the heave-ho from the galactic enlargement equation, Villata supposes that the idea of common relativity applies in reverse to antimatter particles to create anti-gravity. And simply as gravity pulls particles collectively, anti-gravity shoves them aside — giving the universe its burgeoning waistline, no clown, king, or colonel required.
