...grand design, has been made known to man mainly through the free inquiry of science. The true study of evolution, moreover, is a humbling experience that gives man only a tiny niche in the vast scheme of the universe. "Never lose a holy curiosity," Einstein once wrote. Says Astrophysicist Robert Jastrow: "Astronomers have proven that the creation of the universe is the result of forces beyond the reach of scientific inquiry, but the rest of the story, leading from the creation to man, is explained very well by the scientific evidence in the fossil record...
David N. Schramm, a University of Chicago astrophysicist, speculates that relic neutrons--those left over from the Big Bang, the gaseous explosion believed to have formed the universe more than 9 billion years ago--outnumber the protons, neutrons, and electrons that comprise ordinary matter by about 10 billion to 1. The average cubic centimeter in the universe contains about 450 of these relic neutinos. Schram contends that if these particles have even a tiny mass, unlike the current description of conventional physics, scientists can construct a radically different view of the universe and explain several cosmological riddles...
...Sagan's Cornell laboratory, one of the main objectives was to try to unravel the mystery of how the building blocks of life?amino acids, proteins and DNA?could have evolved on the primordial earth. Although he and the Russian astrophysicist I.S. Shklovskii lived half a world apart, they collaborated in writing Intelligent Life in the Universe, still probably the best treatise on the prospects for extraterrestrial life. As a planetary expert, Sagan was called upon by NASA to act as an adviser and scientific investigator on unmanned space missions. He did not always endear himself to the space agency...
...probably a black hole. The qualifier is needed because we are still learning how to grope in the dark, to sift through the clues contained in invisible radiation. Like the archeologist who digs through ancient rubble in search of hints about the origin and evolution of culture, the astrophysicist interprets radiation, seeking clues about the origin and evolution of galaxies, all of which may have black holes in their hearts...
