the energy from the core never reaches the surface
|
Detailed explanation-1: -A photon of light takes only eight minutes to get to the Earth from the surface of the Sun. But it can take 100, 000 years from the core of the Sun to get to the surface-where it bursts out and flies at the speed of light.
Detailed explanation-2: -Sun is high density mixture of Helium, Protons, Electrons and other atomic particles. At core, the energy is released in the form of Gamma Rays. At the core, protons and helium nuclei are so thick that an emitted gamma ray can’t get very far before it is absorbed.
Detailed explanation-3: -Interestingly, although it may have taken the energy a million years to reach the convection zone, the energy it delivers rises through the entire convection zone in about three months. It is important to realize that all of the energy emitted at the surface of the sun is transported there by convection.
