the fact that we understand so little about the Sun suggests that there are plenty of new theories and pieces of evidence to uncover.
There are many questions that need answering. For example, the Sun’s heat energy does not act in the manner that many would expect. Typically, if you move away from a heat source, the temperature declines. The surface of the Sun has a temperature of about 6,000 degrees, yet a few thousand miles above its surface, that rises to well over one million degrees. This heat ring around the Sun, the solar corona, is what we see during a solar eclipse. But how can this phenomenon be explained?...
I love it when the science isn't settled. What else isn't known about the sun's influence?
