Cygnus (NOTE: Subscribers can still listen to this show), also known as the Northern Cross, is one of the constellations you see in the nightsky. It looks benign but that may be deceiving: Some astronomers think it’s sending out a cosmic wind that blows thousands of times faster than a Category 5 hurricane.
So why don’t we feel it? Because this wind is made up of that mysterious substance called dark matter, which passes through most ordinary matter without leaving a trace. Dark matter is moving through you (and everything else) constantly, at a speed of over 500,000 mph.
The Kavli Institute website quotes physicist Peter Fisher as saying that gravitational theory requires the existence of dark matter to explain “why our galaxy looks the way it does. The hard part isn’t coming up with something that detects dark matter. The trick is to discriminate dark matter from everything else.”
