wHAT IF (ON SPECTRAL LINES)
Well Newton used a prism to split light into their colours,but it was
a German lens maker that created the dark narrow spectral lines and these lines revolutioned chemistry,and astronomy O ya) At a much later time we realized what these lines were telling us. I think of them as fingerprints. Each line tellinvg us how each element absorbs,and emits its own characteristic combination of wave lengths Did we not find helium in the Sun first O ya It even showed us the universe every where is made of the same elements here on earth. I even have the spectral lines of Sirius in my scrape book Bert |

Seems 95% of the matter in the universe does not send out EM energy. It only sends out gravitation. We can feel gravitation. We can detect what it is doing. Still if its invisable we think its not there. TreBert |
