I've returned from google, I've heard of this before and already know my counterargument.
Look I'm someone who believes the scientific community told and have maintained a 500 year old lie regarding globe earth, I also believe that NASA CGI and edited all of their evidence and not only deceived the entire public, but was successful for decades.
So, this pendulum I just have to say that in 1850 they BS'ed it, and all of the modern ones, if not BS, just use the electromagnets or whatever other third party force to fake it.
Seems odd this is the only device in the world that tracks the rotation, and it took until 1850 to make one, and we can only replicate this thing, we can't make any new devices to do so.
Let me try a new approach, maybe we are all just too patriotic from living inside the machine.
Would we be willing to consider that China fakes their space program?
