… end in fire or ice … or neither?

When our star (Sun) uses up it’s hydrogen envelope fuel, it’s liquid fusion core would seem to shift to a solid fission core, with a diminution of light; but with even an enhancement of heat luminosity. Hence our perpetual night sky and oceans might be reasonably warm, consistent with tri-phasic water on the surface etc. Could nature adapt? Could plant life adapt to energy influx in just infrared; already have? Perhaps broad-leaved ‘solar panels’ absorbing in infrared, resulting in convection of fluids for a ‘heat engine’, together with separation of charge and electron transport, in a general warmer and hence more ‘catalytic’ environment?(4) Infrared radiation can result in chemical bond vibration i.e. change in bond length and rotation; thus enhancing reactivity. Even natural selection from what already exists could become more predominant. For example, one has mechanical stress (i.e. force) induced chemical reactions. (1,2) One example is ATP synthase of inner mitochondria membrane, and ATPases in plant chloroplasts, yeast, and bacteria; wherein a torque on such enzyme, together with proton gradient, is associated with ATP synthesis from adenosine diphosphatate and another phosphate.(3) Would life in oceans and on land then seem unending? Hence an optically dimming Sun would not seem to lead to a frozen surface; and perhaps not to a marked diminution of surface life – indefinitely for overall age of universe? TMM

Some say the world will end in fire,
Some say in ice.
From what I’ve tasted of desire
I hold with those who favor fire.
But if I had to perish twice,
I think I know enough of hate
To say thay for destruction ice
Is also great
And would suffice.
