How to build a warp ship and then blow it up
Numerical relativity is a tool for studying the behaviour of spacetimes where non linear gravitational effects are significant. As well as being important for gravitational wave data analysis, these simulations provide a means to do modern day “thought experiments”, to study the consequences of scenarios beyond GR and the Standard Model. I will use a warp drive bubble as a toy example of how to set up these simulations, the challenges involved and what kinds of information we can extract from them. This talk is based on the work in https://astro.theoj.org/article/121868-what-no-one-has-seen-before-gravitational-waveforms-from-warp-drive-collapse.
