Self-organized Session

Just one sign switched and all of physics changes: Moving objects lose kinetic energy instead of gaining it and radiating objects get hotter instead of colder. Infinite velocity and infinite temperature are no longer impossible. Stars look like rainbow-colored lines instead of white dots and turning your arrow of time around into your own past is just as easy as turning from left to right. In this talk, we will explore the physics in a spacetime with signature (+,+,+,+) as presented by Greg Egan in the trilogy „Orthogonal“.

For everybody. No prior knowledge required. (Knowing metrics is helpful, but they will be explained.)
