Tired 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...
Meanwhile, he will look for evidence that the "red shift" does not indicate speed but is due to some other effect, such as light getting "tired." Hubble does not expect such evidence, but will welcome it if he finds it. Tired light, he thinks, would be a discovery quite as sensational as the exploding universe...
...billion-light-year range of the 200-inch. Behind this humdrum-sounding chore lies the eerie, brain-staggering problem of the curvature of space. Mathematical physicists believe (from Einstein's ubiquitous Relativity) that space is curved back upon itself, in a four-dimensional way, by the gravitational effect of the matter it contains. The curvature is too slight to be detected on earth or even in the enormous sphere, 500 million light-years in radius, penetrated by the 100-inch telescope. But theory hints that doubling the radius to the billion-light-year radius of the 200-inch...
...peak of 155-165 million by the end of the century. But the "present surge of births," said the Record, indicates that the peak will actually be from 10 to 25 million higher and the crest of the growth curve has now been pushed beyond the year 2000. In effect, the U.S. economy, which was once regarded by some as "mature," has a long way to grow...
Under the leadership of Mt. Holyoke and the College, the bi-regional convention voted to survey New England colleges to determine how much effect racial discrimination has in the decisions of college admissions and employment boards. Attempts will also be made to measure the approximate strength of intolerance among New England students...
