Description
Summary:In 2013 a new metric called TARDIS was introduced. This metric was published by Tippet and Tsang, and described a time machine. This thesis uses numerical methods to explore properties of this new metric. We start by visualizing geodesics in two and three dimensions, then we see that there is a really high blueshift when the light rays hit the borders of our time machine, but when we drop an approximation made by Tippet and Tsang, we find that the blueshift almost disappears. We use the Darmois-Israel junction conditions to see that it is possible for this time machine to travel anywhere in time and space. Finally, we calculate the energy-momentum tensor corresponding to this metric and find that it requires exotic matter, which makes it hard to construct this time machine in real life.
