THE MIRACLE OF VISIBLE LIGHT
Not all the stars and other sources of light in the universe
emit the same type of radiation. Different types of radiation are
classified according to their respective wavelengths. They fall
along a huge spectrum, with gamma rays being the shortest and
radio waves the longest. The difference between these shortest
and longest waves is 10 25 (ten times billion times billion times
billion). Miraculously, most of the Sun’s radiation lies in the
same bundle of wavelengths within this vast spectrum, because
only that narrow band contains the radiation necessary to sup-
port life.
The vastness of this spectrum becomes clearer when you re-
25
alize that the shortest wavelength is 10 times shorter than the
25
longest. 10 is written out as a 1 with 25 zeros following it, like
this: 10,000,000,000,000,000,000,000,000. To fully comprehend the
magnitude of this number, it helps to make some comparisons.
For instance, the 4.5 billion years that have passed since the
17
Earth’s creation can be converted to 10 seconds. If you wanted
25
to count to 10 , you would have to count day and night for a pe-
riod 100 million times longer than the age of the Earth. If we
25
were to pile 10 playing cards on top of one another, we would
leave the Milky Way behind and cover about half the distance
of the known universe! 38
The different wavelengths in the universe are spread across
that wide a spectrum, but within it, interestingly, our Sun covers
only the narrowest bandwidth. 70% of the Sun’s radiation has
wavelengths between 0.3 and 1.5 microns. Within this narrow
