...McDonald (1), but because they haven't yet officially notified the town of their trip, no activities have been planned. What can the Clintons do? Some suggestions: Krebs' (2) is the best spot to blend in with the locals and quaff a brew. If Hillary is looking for a light bite, Angel's Heavenly Hamburgers (3) already has a sandwich named after her. It's a hard roll with lots of baloney. Bill can tee off at the country club (4), but buying cigars at the Havana Trading Co. (5) could be politically sensitive, and the town has--horrors...
...Foster rips off her earphones in astonishment after hearing four telltale beeps. Pure fiction, say scientists--and not only because of her hokey headset. When extraterrestrials finally make themselves known, they may not use radio at all. Instead, they're just as apt to signal us with beams of light. Says physicist Freeman Dyson of the Institute for Advanced Study in Princeton, N.J.: "It's foolish to try to guess what an extraterrestrial civilization might use. You ought to try all available technologies to detect...
...Harvard's 61-in. telescope as it conducts regular studies of starlight. While stars typically pulsate comparatively slowly, Horowitz's device is calibrated to spot intense stellar flare-ups lasting only a few billionths of a second. Such "events," he figures, would probably be powerful bursts of artificial light aimed at us from an inhabited planet orbiting that star. In short, an interstellar hello...
...like OSETI mania. At Princeton, physicist David T. Wilkinson will soon begin surveying nearby stars with a detector similar to Horowitz's. At the University of California, Berkeley, extrasolar-planet hunter Geoff Marcy is re-examining his data for sharp spectral lines that might indicate a continuous beam of light intended as a low-power signal. Another Berkeley team, led by SETI veteran Dan Werthimer, is looking for short, powerful laser bursts in a series of automated observations of 2,500 nearby stars. Later he plans to turn to invisible infrared light and other galaxies...
...against them. In order to find a heavenly body, sky gazers ordinarily take a straightforward approach, hoping simply to eyeball the object through a telescope. But black holes, which are formed by collapsed stars or compressed matter at the center of galaxies, are so dense that nothing--not even light--can escape their gravity. Last week, however, investigators at NASA's Goddard Space Flight Center in Greenbelt, Md., announced that they had at last seen direct evidence of a black hole in action...
