S02E02 - [Pt 1] Time travel and time loops with Dr Gaurav Khanna and Caroline Mallary

In part 1 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. The theory of time travel and time loops we discuss require two long spaceships parked in parallel. One moves forward really fast, while the other is parked. Caroline explains that a time loop forms between the two cars such that space and time folds on itself. Although almost impossible to create and imagine right now, the science is now here and we have just witnessed another breakthrough in space-time.
