re: In the real world. Hair care ?

I agree with you on most parts, but would like to ‘split hairs’ on some other parts.

W-- The temperature on the Moon is 252F - 325F. That's hot man!
J— Definitely very hot compared to absolute zero or even 2.7 K degrees.

W-- No problem there there's no atmosphere.
J— Depends on what is considered an “atmosphere”. If we found 1000 molecules floating close to the surface, would that be considered an atmosphere?
I remember watching television when the first men landed on the Moon, when they decompressed the LEM, the pressure did not go below a certain figure, if my memory serves me correctly, the figure was 4 lb. per square inch. My assumption is that this figure, whatever it was, represents the atmospheric pressure of the Moon.

W-- No one ever talks about the average temperature of the Moon.
J— I wonder why?

W-- Is this the Black Ball or is it the Black Wall?
J— Good question

W-- Comparing the surface heat of Earth and Mars is not straight to the point. The fact is It's to hot for life on Earth in some places.
J— Depends on what you mean by “life”, humans certainly could not live in many of the places where microbes are found. What is the fundamental meaning of the word “life”? In my opinion fundamental meaning of the word ‘life’ refers to motion; being ‘alive’ refers to ‘controlled’ or 'conscious control’ of motion. In other words an electron orbiting around an atomic nucleus has ‘life’ but is not considered to be ‘alive’, even if that atom is part of your body.

W-- But Earth is in the prefect position have equal areas of tundra and desert, maximizing the area for abundant live, generally speaking. My guess is it's the ocean glint that does it.
J— Good point, I wonder if the amount of radiation that is reflected by the ocean glint has been measured.

W-- So you really need to compare Mars with the Moon. IMHO
J— That attitude may bring our minds into sharper focus about the laws of nature.
Thank you Woodlock for bringing interesting information to light.
