A new study published in Physical Review Letters presents evidence for the creation of matter and antimatter from energy, specifically light particles (photons). In doing so, it offers a splendidly concrete example of the world's most famous equation: E=mc2. The equation, derived by Einstein, dictates how energy (E) is equivalent to mass (m) times the speed of light (c) squared.

KB: We asked ourselves, "what obliquity, what misalignment would Planet Nine induce in the solar system?" because it must induce some. We know that Planet Nine's orbit in inclined. As a result, when Planet Nine torques the rest of the solar system, the two sort of act as two precessing tops.

A subatomic particle has been found to switch between matter and antimatter, according to Oxford physicists analyzing data from the Large Hadron Collider. It turns out that an unfathomably tiny weight difference between two particles could have saved the universe from annihilation soon after it...
