I stumbled upon your comment again and would like to ask for a few decent sources concerning the truth nature of our earth and this force of 9.8m/s we call gravity. Can you point me in the right direction where I can understand that an accelerometer is truly accounting for upwards velocity of earth when stationary? I have read and the mainstream science will say that is because the force of “space time” and gravity is acting on it while stationary. TL;DR - please send me some good sources to read about earths upward velocity.
