They have never detected a universal gravitational constant in an exoeriment that a person with less than $1000 and no government or corporate or academic special clearance can do
Alleged affordable universal gravitational constant experiments ignore the mass of buildings, walls, and the human taking measurements
It is possible to calculate the local gravitational constant for less than $100
With a ball, a ruler, a camera, & a screen to watch a video
& paper for calculation

Red shifting is not caused by all objects moving away from the observer in a expanding universe due to a big bang but through light traveling through a medium & possibly other factors
Expensive telescopes that only certain people can access could potentially not even exist & fake pictures could be made that are claimed to come from them
The first moon landing video was at least partly a simulation, it said the words simulation in big letters in some portions of it
