It is not sufficient to simply say that high temperature leads to high speed, for example. You need to explain why high speeds are necessary. Explain how cold fusion supposedly works at such low temperatures. In the Sun's corona, we know that the temperature of the gas is higher the further away you look from the surface of the Sun while the density of gas is lower the further away you look from the surface. As part of your answer, explain why ionization species are related to the temperature of the gas.
Irrefutable beliefs can be very compelling.
The fact that these beliefs can't be disproven can be comforting, providing us with a basis of unchanging truths about the way the world works. However, this isn't the whole story.
