Appreciate the earnest conversion and a good place to conclude: we'll see.
Yes, I think it's complete BS, including the fundamental principles that it's built upon. In my opinion, it's just another money-pit boondoggle like CERN and the vast majority of quantum theory and mathematics (string theory etc.)
When people start talking, and publishing paradigm-shattering papers solely based on thought experiments like trains moving at light speed, bowling balls on trampolines, and dead cats in boxes, that's a signal to take a hard look at the math and evidence.
I'd change my stance if presented with legitimate, verifiable evidence, but this latest paper certainly doesn't make the cut.
If someone can't explain something in simple terms, then they don't understand it or they're just bullshitting.
Many people point to all of the PhDs and funding as evidence, but I see these as a motive to continue the con.
