I've seen things you people wouldn't believe. Rodents eating herbal remedies. I watched a truck mistaken for an alien message. All those moments will be lost in time, like the Upper West Side under land subsidence.
Sound waves thought to be from a 2014 meteor fireball north of Papua New Guinea were almost certainly vibrations from a truck rumbling along a nearby road, new Johns Hopkins University-led research shows. The findings raise ...
