Given that the Sun has a mass of 1.989 x 1030 kg and that each proton-proton chain reaction (the fusion reaction that turns 6 hydrogens into 1 helium and 2 hydrogens) releases 26.73 MeV, how long would the Sun take to use up all of its hydrogen supply

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.
