The Sun is a rotating mass of plasma and gas. It’s big. Most of the mass of the Solar System resides in the Sun, and this star of ours dwarfs all the planets, even big Jupiter. Astronomers have long noted that the Sun undergoes a differential rotation. Some parts, notably those of the interior, spin faster than other parts, notably near the top of the photosphere. The slowdown, according to Ian Cunnyngham, Marcelo Emilio, Jeff Kuhn, Isabelle Scholl, and Rock Bush, might be the result of something similar to the Poynting-Robertson “photo braking.” In short, as the Sun sends out photons, the sending slows the outermost photosphere by removing angular momentum.*
Photons rob part of the Sun’s angular momentum. Think about that. The biggest mass in the Solar System loses part of its angular momentum to virtually massless particles.
Don’t let the little things rob you of your energy and keep you from reaching your goals. But note this. Overcoming the effect of energy-robbing little things requires knowing how to handle them while keeping your energy focused on your goals. The slowing need only be superficial and similar to the Sun’s slower rotation in a thin 70-kilometer thick layer in the outer photosphere. That big mass in the interior keeps running at a fast rate. Yes, you will lose some energy, but you don’t have to lose the greater part of your momentum.
