Dark Matter—A Matter of Faith?


Does ‘Dark Matter’ to Philip Pullman?...

Dark Matter… “Dust” … call it what you want… It makes up 90 percent of our universe, according to astronomers. This makes the kind of matter that you and I see rather exotic; while we must accept the existence of the most common element, dark matter, on ... well ... faith. You see (oh, another bad pun!), dark matter doesn’t emit or reflect light and doesn’t interact with what we think of as ordinary matter. Yet, this invisible particle is faithfully being credited with playing a crucial role in shaping the visible cosmos. Dark matter is some form of matter theorized to exist that cannot be observed by radio, infrared, optical, ultraviolet, x-ray or gamma-ray telescopes and is theorized to be MACHOS, WIMPS, or GAS (see this site for more info on this incredible particle).
