Does a Quantum Equation Govern Some of the Universe’s Large Structures?

Researchers who want to predict the behavior of systems governed by quantum mechanics — an electron in an atom, say, or a photon of light traveling through space — typically turn to the Schrödinger equation. Devised by Austrian physicist Erwin Schrödinger in 1925, it describes subatomic particles and how they may display wavelike properties such as interference. It contains the essence of all that appears strange and counterintuitive about the quantum world. But it seems the Schrödinger equation is not confined to that realm. In a paper just published in Monthly Notices of the Royal Astronomical Society, planetary scientist Konstantin Batygin of the California Institute of Technology claims this equation can also be used to understand the emergence and behavior of self-gravitating astrophysical disks.
