A short clip featuring our very own science mama Sabine Hossenfelder. Here, she is discussing time travel and speculates that while moving backward in time might not be possible, faster-than-light travel just might. If that´s good news or bad news is, of course, another matter entirely. For starters, where do we find all the energy necessary to accelerate a space rocket to a speed faster than light? Something tells me it won´t come from CERN´s particle accelerators...
