Hi, I am a theoretical physicist, during my free time I run a YouTube channel for physics nerds (www.youtube.com/@jkzero/). Trying this platform in an attempt to rediscover the great astro/physics community that existed on the other site.

Why even physicists still don’t understand quantum theory 100 years on
Quantum mechanics depicts a counter-intuitive reality in which the act of observation influences what is observed — and few can agree on what that means.

head over r/AskPhysics, every day there is a new set of "theories" that "prove" relativity or quantum mechanics wrong and new methods of FTL communication via quantum entanglement. Why do crackpots never have "theories" solving specific physics problems? Their ideas always have to be so grandiose.
Dear people with "theories",
I will happily read your idea and take it very seriously for the right donation. $10,000 per hour I spend reading and debunking it. All money goes towards research on stars and exoplanets.
