The Sun's Surface Spins Slower Than Its Core Until It Stops, Physicists Bare Why

Physicists have argued that the sun's outward energy draws back in substantial amount of energy to create a resistance that affects its rotational movements in all its layers.

Just in case you don't know this yet about our Sun, let me tell you now that the new observation suggests that the core spins faster than its surface, but the mystery is - why? Now scientists have finally come up with the physics behind such phenomenon.

Scientists have known for a decade that the sun's main layers: plasma surface and core, spins relatively like a nut and bolt. The outer layer spins 5 percent slower than its molten core. Scientists have not really established a concrete, standard explanation on the sun's shearing motion. Now a group of physicists established the result from their observation using two fundamental ideas of astrodynamics as Science describes it as, Einstein's theory of relativity, which states that photons of light carry momentum and Newton's third law which stipulates a reaction for every action. “It slows down from the outside to the inside, and it will gradually slow down all the way to the interior, it’s just a matter of time,” says Jeff Kuhn, lead author of the study and a physicist at the University of Hawaii’s Institute for Astronomy in Honolulu. Don't get too worried, we would've to live a million lifetime over the same course as the universe's age before the sun grinds to a halt. Their observations are favorable to that stated idea. They have calculated that the rate of the gradual slowdown of the surface spin relative to the pushback of energy and resistance of plasma's thickness is 2 percent difference. The calculation was also derived in the shear line between the sun’s 150-kilometer-thick outer skin and the 35,000-kilometer thick layer underneath.

Note: This is not the actual rate that the sun is spinning on its axis.

Kuhn's team has also confirmed the calculation base on the brightness and age of the sun. NASA’s Solar Dynamics Observatory, a space-based telescope purposely created for the sun's observation, confirms the observations made by the team at University of Hawaii's Institute. The study which will be reported next month to Physical Review Letters, will add to the understanding of the effect of stellar rotations in the surrounding celestial bodies and the life cycle of stars.
