I understand where you are coming from believe me. All the fields of study you mentioned have different thinkers on the subjects. Measuring gravity is a tricky one.
Discussion
Fair enough, but how do you explain the fact that our current knowledge of physics works perfectly? The phone you are typing from is undeniable proof of that, also how does GPS work on a flat earth? How do inertial navigation systems work without gravity? How does starling work?
I am just a pleb with questions too.
One of my fav videos explaining the cavendish experiment and the mystery of the supposed torsion rod. You can tell the guy isn’t trolling, he’s just asking questions. Towards the middle/end is the meat of the video. TLDR he thinks cavendish reverse engineered big G since nobody has a working torsion rod to do the experiment.

Starlink/satellites are said to be hanging from high altitude helium balloons. This makes sense when you look up how much helium space agencies use.
But you can literally see satellites and the ISS with a telescope, also I saw myself starlink satellites aligning with their lights on, quite an interesting sight
