The Penrose Process, the Penrose Energy

Geometry is one of those mathematics that i have a fondness for. And with the penros id process, penrose energy, what what's amazing is how this is fundamentally still getting used every day. This very week, we had a new article come out talking about how it's been determined that our galaxy supermassive black hole can't be ting that quickly because it isn't injecting energy into the orbiting stars around it. Ye our ability to figure out we have a slow rotating black hole, through decades of literature, derives from this whole penrose process.
