...that the orbit of Mercury wobbles in a certain way -- were confirmed within just a few years, convincing scientists that relativity was a revolutionary discovery, not just a mathematical curiosity. But Einstein thought another of his claims would never be proved. His theory predicted that fast-moving, massive objects emit gravity waves, small distortions moving through the fabric of space and time. Einstein said these waves would be virtually undetectable, and it was not until a few years ago that physicists began their so far futile search for the elusive ripples...
...federal truth-in-advertising and mail-fraud laws. But these weapons have generally been used just against products that are truly outrageous. The Postal Service, for example, took action against diet sunglasses, which supposedly altered food color and made meals appear less appetizing, and a satin headband designed to emit electromagnetic waves that, according to the manufacturer's claims, help customers refuse to eat calorie- laden foods...
...least a 15% reduction in the production of ozone-destroying chlorofluorocarbons. But Washington is letting the four CFC manufacturers decide how to allocate the pain; they can buy and sell CFC production rights. Senator Wirth thinks that global warming could be countered by international trading of permits to emit carbon dioxide and other greenhouse gases...
...with California's pollution laws, which are the strictest in the U.S. and will become even tighter in the 1990s, when they are to serve as models for the rest of the country. Such 1989 cars as the South Korean-built Pontiac LeMans and Japan's Nissan Maxima emit less than 0.2 gram of nitrogen oxide per mile. At the same time, Chrysler sells its California dealers a $100 pump that helps cars meet restrictions by recirculating exhaust through the engine and catalytic converter to reduce toxic emissions...
...high-energy electrons, deflected by the earth's magnetic field, spilled into the upper atmosphere near the north and south polar regions, which are unprotected by magnetic-field lines. Acting much as does the electrical current in a neon sign, the electrons banged into oxygen atoms, causing them to emit red and green light...
