Join Tom and Mitch this week as they round up their space themed episodes, talking about space travel to find out about the potential propulsion systems that we may use to get to other planets and how far we may expect to go in the future... will we ever visit that galaxy far far away? Mitch though hits us with the truth of gravitational time dilation! How might it affect space travel in the future? AND how does it affect us now? Music: EVA – 失望した
