A THEORY is a pattern in nature thought to have predictive power. The test of a theory is a prediction. That's where pseudo-science fails. T/F - Answer-T Red giant stars are powered by hydrogen burning in a shell surrounding a core, which has been depleted of hydrogen. T/F - Answer-T Jovian planets have densities similar to that of water, and we know in fact that they are mostly made of water. T/F - Answer-F - Jovian planets are gaseous The Sun appears to circle the Celestial Sphere in on...
