A Flash of Lightning
by Robert Scherrer
High school student Terri Bradbury and her high school class take a field trip to the
distant past where Mr. Schoenfield sets off a nuclear explosion to experimentally study
three theories of time travel’s effect on the future.
We’ll discuss the ethics of time travel in the spring semester.
