...David R. Layzer '45, professor of Astronomy, has proposed a new theory to describe the state of the universe "long before stars or galaxies existed...
...Layzer argues that matter first existed as unorganized dust. In this early state the universe was only moderately warm. As it lost energy into space, however, it began to make up its losses by gravity. Pressure built up, and its temperature rose...
Scientists at Bell Telephone Laboratories last year detected a band of microwave radiation from a specific celestial source. It is this radiation, Layzer argues, that in the degraded remnant of that energy which this pressure produced billions of years...
...Layzer's theory also helps resolve what is known as Olber's Paradox on the night- time...
According to Olber, Layzer said yesterday, the light produced by faraway stars should make the night sky intensely bright and hot. Obler reached this conclusion after observing a "shell" of stars at a given distance from the earth. While the brightness of the stars will diminish with the square of their distance, Layzer said. The area of the shell--and thus the number of stars on it--will go up it the same rate...
