According to UA,FE accelerates upwards at 9.81 m/s². That means, it would have reached relativistic velocity within less than a year and we are currently travelling very close to light-speed.
The stars are travelling at negligible velocities and independently from Flat Earth. That means, when the photons enter our moving frame of reference, they will get a blue-shift.
1. Element-specific spectral lines of the stars, of our Sun, of gas-lamps in the lamp, they would all be different from each other (bc blueshift) if UA were true. Except they are identical.
2. The blueshift would mean that starlight coming from directly above would be blue or violet. As we are moving close to light-speed, it is reasonable to assume, that the blue-shift has already shifted starlight beyond the visible range. Accordingly, if UA were true, there would be no starlight coming from directly above.
Could you please update your wiki? Thx.
