One of the most popular scientists on television, astrophysicist and author Neil deGrasse Tyson is just plain fun to watch talk, thanks to his infectious enthusiasm for all things science. He gets the public excited about the scientific method, always a good thing. An agnostic, Tyson brings his lighthearted show “An Astrophysicist Goes to the Movies” to Richmond on Wednesday, Nov. 15, at the Altria Theater, where he looks at popular sci-fi movies and proceeds to rip their authenticity to shreds — in delightful fashion, we might add. 7:30 p.m. $45 to $69.50.
