You’ll get a sore head banging it against God. Think of plate tectonics for an example of light and heat without nuclear fusion. Melted ice as well . . .
(Q)Think of plate tectonics for an example of light and heat without nuclear fusion.(/Q)
I’m glad you take such pleasure at my frustration - what would Jesus say about that?
At any rate, I don’t think you understand plate tectonics. Plate tectonics may generate some heat due to friction, but this heat is negligible compared to the heat left over from the Earth’s condensation into a solid mass, (and the subsequent collision with a Mars-size planetoid a billion years after its formation which created the Moon, and caused Life to start all over again), and the natural heat given off by radionuclides which are spread throughout the lithosphere, and below in the outer and inner core. The plates “float” on hot, liquefied rock known as magma. Plate tectonics do not give off any visible light, unless there is a volcanic eruption and glowing magma from deep below the Earth’s crust makes it way to the surface. It is so hot that it glows in visible orange, yellow or red as it cools. Only Infrared light is given off by plate tectonics, and not very much at that. Plants do not live by IR light, but by UV light, and some frequencies of visible. Plants require the spectrum of light which the sun gives off, as they evolved to do this.
The main form of light, and radiation in general, in the Universe, is thermonuclear fusion in the cores of stars.
And I haven’t been banging my head against God, I’ve been banging it against some folks who are clinging desperately to archaic superstitious beliefs because they fear their own (God-given) mortality.
