Whatever
it is, dark matter may not move in mysterious ways, researchers
told this week's American Physical Society annual meeting in Philadelphia,
PA. They calculate that this elusive matter which makes up 80
percent of the universe shifts around much as does the visible
matter of stars, planets and dust. If these globs of dark matter
exist, their gravitational fields will bend the light from distant
objects, such as exploding stars, on its way to Earth, explains
astronomer Saul Perlmutter of Berkeley Lab. Such differences
may show up in future surveys of dying stars. Full
