In part 2 of our two-part series we are joined this week by Caroline Mallary a PhD student at the University of Massachusettes and our past guest Dr Gaurav Khanna from Episode 1 on Hyperspace. This episode is more focussed on time travel where last week's episode we dove right into time loops. Caroline Mallary has discovered that her time machine, although in its simplest form, does not need exotic matter... matter once thought to be required if a time machine was ever to be built.
