The Sun’s Rotation Appears Differential Plus Other New Views: A Novel Perspective

When observing extended objects such as the sun, it is critical to remember that the speed of light is finite. This is a novel perspective on the sun that takes into account its enormous spherical size in proportion to the finite speed of light. The sun is so extended that it takes light approximately 2.32 seconds to travel from the plane of the solar limb to the plane tangential to the sun at the solar disc’s center. The aforementioned details are used in this study to strengthen the novel viewpoints. Firstly, it is shown that the solar disc is a simultaneous view of successively emitted coaxial spherical circles. Secondly, despite the fact that the sun is gaseous, it is thought to revolve completely as a rigid body at a fixed angular speed, yet an observer on Earth sees it rotate differentially. A simple mathematical analysis reveals that the speed of rotation of the sun appears to decrease with latitude. Thirdly, a qualitative examination of how we notice simultaneous whole-surface brightness changes of the sun and sunlike stars indicates that such changes would appear to spread out radially from the center of the solar disc. It has also been illustrated that the star would appear to be expanding or exploding while fading out.
