How do scientist make the determination that the sun's rays contain Vitamin C and E?
Do scientists have some magic trick up their sleeves to calculate that the sun’s rays contain Vitamin C and E? The rays from the sun are not liquid, so a computer cannot calculate this information. The rays from the sun cannot be captured in a bottle to give them this conclusion.
Question: so, how do scientist come to the conclusion that the rays from the sun contain Vitamin C and E and other essentials, so important for the survival of man on earth?
