Unfortunately, with every attempt to educate the poster ... the comment gets blocked.
To the OP of this thread:
evidence to show the earth is rotating (proof is for mathematicians)
- Foucault pendulum
- the existence of a geostationary orbit
- the location of Lagrange points between sun/earth just like earth/moon
- HUGE difference in mass between sun and earth
- angular deviation in long range projectiles
- higher centrifugal force at the equator (... which is also the reason space launches are conducted at or at least near the equator to save fuel, and they always launch east to get an extra boost to this force)
- coriolis effect
- similar effects of the atmosphere on other planets/moons
- gyroscopes data on earth and in orbital satelites
should the earth stand still:
- enormous speed requirements for the rest of the visible universe should the earth stand still (many, many times the speed of light)
- violation of the sun's conservation of momentum to account for inclination (seasons)
- geostationary satellites fall to earth
... insofar this is still relevant, not repeated for the umpteenth time or even useful to add in a year old thread (but I can't resist)
