Almost all experts on the interstellar medium (actually all but Hoyle and Wickramsinghe) consider their interpretation of the spectral features to be ludicrous. It's not my field, but the criticisms I've heard sounded devastating. -- I'm not afraid of dying Ethan Vishniac, Dept of Astronomy, Univ. of Texas I just don't want to be {charm,ut-sally,ut-ngp,noao}!utastro!ethan there when it happens.
