...call it spiritual therapy," says the Institute of Religion's director, Methodist Minister Dawson Bryan. "You can separate hydrogen from water, but then you haven't got water any more. For years doctors have been treating man's mental and physical ailments, but have been ignoring the spiritual part of him. You can't separate these entirely without destroying the whole person...
Rougoor and Oort are not sure how to interpret their observations. They suspect that the hydrogen disk at the center of the galaxy is rich in stars, but they cannot see them. The stars and hydrogen, they say, are presumably held together by gravitation and revolve more or less as a unit. The outstreaming hydrogen beyond the ring is hard to explain. They calculate that at the present rate of flow, all the hydrogen should have been drained from the nucleus in a mere 10 million to 100 million years, which is only a tiny part of the life span...
...radio waves pass through cosmic dust clouds. By tracking the 21-cm. waves given off by hydrogen, radio astronomers have been able to probe deeper and deeper through the Milky Way toward the galaxy's center. Recently, Dutch Astronomers G. W. Rougoor and J. H. Oort of Leiden Observatory reported that they had been able to peer into the mysterious nucleus itself. They found there a strange pinwheel of rapidly spinning hydrogen...
...Dutch astronomers found that for 15,000 light-years toward the center, clouds of hydrogen fill the spaces between the stars, revolve around the center with reasonably circular motion. Then, 10,000 light-years out from center, comes a rather dense spiral arm of hydrogen that is moving away from the center at 100,000 m.p.h. Other hydrogen clouds in the vicinity may be moving outward as fast as 400,000 m.p.h...
Fiery Pinwheel. Behind these out-streaming clouds Rougoor and Oort found a ring of hydrogen about 300 light-years wide and encircling the galaxy's center at a distance of 1,600 lightyears. It appears to be revolving at a good clip (600,000 m.p.h.). Inside it is a band of almost empty space; then comes a rotating disk of hydrogen whose density increases toward the center. Neither ring nor disk appears to be moving outward. They are like the solid part of a fireworks pinwheel, which spins rapidly and throws off spirals of sparks...
