sunny summer or spring day is caused by infrared radiation coming from
the Sun.
The Sun's infrared radiation is what carries the thermal energy that
keeps Earth warm. It too is as essential for life as visible light is. And the
fascinating thing is that our Sun was apparently created just to serve for
these two purposes, because these two kinds of light make up the greatest
part of sunlight.
And the third part of sunlight? Is that of any benefit?
You can bet on it. This is "near ultraviolet light" and it makes up the
smallest fraction of sunlight. Like all ultraviolet light, it is highly energized
and it can cause damage to living cells. The Sun's ultraviolet light howev-
er is the "least harmful" kind since it is closest to visible light. Although
overexposure to solar ultraviolet light has been shown to cause cancer and
cellular mutations, it has one vital benefit: the ultraviolet light concentrated
in such a miniscule band 69 is needed for the synthesis of vitamin D in hu-
mans and other vertebrates. (Vitamin D is necessary for the formation and
nourishment of bone: without it, bones become soft or malformed, a dis-
ease called rickets that occurs in people deprived of sunlight for great
lengths of time.)
In other words, all the radiation emitted by the Sun is essential to life:
none of it is wasted. The amazing thing is that all this radiation is limited
25
to a 1/10 interval of the whole electromagnetic spectrum yet it is sufficient
to keep us warm, see, and allow all the chemical reactions necessary for
life to take place.
Even if all the other conditions necessary for life and mentioned else-
where in this book existed, if the light radiated by the Sun fell into any oth-
er part of the electromagnetic spectrum, there could be no life on Earth. It
is certainly impossible to explain the fulfillment of this condition having a
probability of 1 in 10 25 with a logic of coincidence.
And if all this were not enough, light does something else: it keeps us
fed, too!
