The Loop Quantum Gravity War

A few weeks ago, I released a video about whether string theory’s biggest competitor, Loop Quantum Gravity, might have suffered a fatal blow. The video sparked a lively debate across YouTube, with creators like Sabine Hossenfelder and Phil Halpern making reaction videos and Carlo Rovelli even reaching out to me personally, asking me to take it down. Now, I want to clarify the situation and share my perspective on whether Loop Quantum Gravity is truly on its last legs—or if there’s more to the story.  Tune in to the Loop Quantum Gravity War!
