There seemed to be no end to the swarming nebulae. The most distant showed as tiny, dim blobs. By a complex statistical method Hubble proved, after years of work, that these dimmest glimmers were so far away that their light, speeding at 186,000 miles per second, took 500,000,000 years to reach Mount Wilson...
Working with short, amiable spectrograph expert Milton Humason, Hubble studied the light of the distant nebulae. In every case he found a "red shift."* The farther off a nebula was, the faster it appeared to be rushing away, and the enormous speeds (thousands of miles per second) were new, strange and startling to astronomers...
...exploding universe theory threw all grades of scientists-from semi-mystic philosophers to earthy materialists-into counterattack. Some critics could not believe that the nebulae move at such breakneck speed. Einstein's Relativity (supreme law of physics) says that nothing can move faster than light (186,000 miles per second). But Hubble and Humason have clocked a nebula about 250 million light-years away that seems to be moving at 26,000 miles per second, more than one-eighth the speed of light. They have glimpsed nebulae twice as far away. If the nebulae continue, on & on into space...
...Light. Other critics question the "red shift" as a measure of velocity. The usual explanation of the reddening effect is that the luminous body's motion away from the observer "pulls out" the light waves, making them longer (redder) than normal. But since red light contains less energy per unit (photon) than violet light, Bubble's critics suggest that light may lose some of its energy in traversing space, thus turning redder. It may start out from a distant nebula as young, vigorous violet and arrive at the earth after millions of weary years as old, tired...
Before the war, singles were among the higher priced rooms in the college, rating above doubles by reason of privacy and greater floor area per man. The Housing Office is continuing a high rent on converted singles even though both prewar advantages have been swept away. It further believes that by adding $40 to the prewar rent for each new man and dividing by the total number of men, it has a sure-cure for injustice in the doubling process. Examination indicates both assumptions to be wrong...
