  In the long history of China, every great dynasty that fell was due to a peoples uprising. When the CCP came into power, it was due to a peoples uprising. They want control over people to prevent another one.

  Its a mass produced bearing type. Most likely the cheapest option for both devices. Optimizing a bearing for a gerbil wheel seems like the real overengineering in my opinion.

  You can lookup the industrial cost of hydrogen in bulk pretty easy. Stop complaining and get some work done.

  Regionally, whenever buildings are build to last the lifetime of more then 1 generation and with a population age curve that is top heavy at this time.

  Respect for the choreographed movements during the tribunal.

• ⁨Comment⁩ on ⁨Do straight lines and flat planes exist in nature?⁩ ⁨⁨8⁩ ⁨months⁩ ago⁩:

  My understanding is that in a true vacuum light will not be reflected or bent by particles. However, due to gravity bending space time itself, light will follow the curvature of space. It would depend on the observer if the path if light is straight. If you look at the light passing by, it would not be straight under influence of gravity. If light itself is the observer, it will travel in a straight line :)

  In the case of gravitational lensing the observer is looking at light coming in. An outside perspective.
