Why Does the Sun Shine?
If we could harness all of the sun's energy that reaches the Earth, we would have more than enough energy to fill all our energy needs – even if the entire world became as industrialized as the west. Yet, less than 0.10% of all of the sun's energy output reaches the Earth! What is going on within the sun to create so much energy?
Most people have heard that the sun produces its energy through nuclear fusion. And even though most scientists think this is true, they admit that the real answer isn't that simple - and the full answer is unknown. If the sun produces its energy by nuclear fusion, one of the results of that process is a tiny particle called a neutrino. But, in fact, the neutrinos that should be coming from the sun are not. Worse, new calculations of the temperature needed for the sun to ignite into the nuclear fusion process show that the evolutionary theory for how the sun formed does not generate enough heat for fusion.
An alternate theory says that the sun's heat is a result of its powerful gravity pulling the sun in on itself – called gravitational collapse. This would explain why the neutrinos are missing. But evolutionists have rejected gravitational collapse because if this is where the sun's heat comes from, the sun could not be billions of years old.
Despite our scientific sophistication, many of God's works still defy our understanding!
