This month we will be clearing up some commonly held misconceptions, starting with the Earth and Moon, then moving out through the solar system, and eventually discussing the Universe as a whole, and some misunderstandings people might have regarding its expansion. To resolve these issues I interview an array of Cornell graduate students: Joyce Byun, Rebecca Harbison, Jason Hofgartner, Michael Lam, Dustin Madison, Sean Marshall, and Eva-Maria Mueller.
