I'm not interested in the content of this page, but it is clear to me everyone agrees we are spinning faster than the speed of sound.
so your we are going so slow argument doesn't hold up.
please stop lying to people. because you either know this is true or you are ignorant of what makes truth.
Yes, knucklehead the earth is moving at about 1000 mph at the equator. Speed and rotation are two separate things.
The earth can spin only once per 24 hours which is very slow. Take a basket ball and spin it once in 24 hours. Would you say the basketball was spinning quickly or slowly?
Quit being a knucklehead and learn something about our reality here: https://www.khanacademy.org/
you seem to think the earth is very small if you think that one rotation every 24 hours is a small thing.
