Did life come from Mars? And should it go back? At least the first question will be discussed by Australian physicist Paul Davies in a free public lecture at UC Santa Cruz on Tuesday night. Davies will present the lecture as popular science, so that people can follow the findings without specialized science training. The lecture will take place at the UCSC Sigma Xi and Physics Department in Classroom Unit 2 on the campus, at 8 p.m. Tuesday.
