| The Sky is Faliing Last spring a story in the new york times said that an asteroid would hit earth in the year 2028.Then a few days after the story scientists announced that they had miscalculated the asteroid's path and it wouldn't hit us after all folks wiped their brows let out a collective "whew"and went about their business. But according to Darren Williams '98 phD Sci, an astronomer and assistant professor of physics at The Vehrend College we're not in the clear yet There are still milions of not billions of asteroids barreling through our solar system every year Usually either they're too mall to penetrate our atmosphere or else they miss us completely but big asteroids tend to have unstable orbits says Williams The gravitational pulls of the planets are constantly tugging at them one could collide with us at any time. |
