That's cause earth isn't actually rotating at all. The entire universe rotates around earth.

Maybe my math is wrong but: The Earth's radius is about 6,371 kilometers. With this large radius and a 24-hour rotation period, the centripetal acceleration at the equator is only about 0.034 m/s². This is tiny compared to Earth's gravitational acceleration of 9.8 m/s². So the centripetal effect is only about 0.3% of gravity's effect.

40,075,000m circumference / 86,400s = 463m/s?

Yes, that is the speed you're going, then the acceleration you experience due to the change in direction as the earths surface revolves about an axis is a = v²/r. R being the radius of the earth. This gets us our small acceleration value.

You do experience this small acceleration as a very small reduction in weight. You actually weigh more at the poles than the equator. You don't feel the velocity at all, as the whole planet is moving with you.

The earth isn't rotating and shaped like a pyramid

[–] [email protected] 3 points 15 hours ago

It's not spinning AND shaped like a pyramid?

...where does the turtle go?

[–] [email protected] 2 points 17 hours ago

If it's not rotating, why is it shaped like a pyramid?

Space doesn't have air dummy

[–] Freefall 2 points 13 hours ago

But earth is in space and I am ALMOST certain earth has air around it!

Uh, is this supposed to be a humorous jab at flat earthers, or do you actually think that this doesn't add up and out yourself as a flat eather and in this case do you wish an explanation?

I was about to say gravity is stronger but it has already been said.

If earth speed + hooman speed = no go

[–] [email protected] 4 points 21 hours ago (1 children)

You see, that is another perfect example for why earth has to be flat, anything else just isn't logical!

Fucking thank you! I was furiously skimming to see if anyone knew! It's totes obvs that the ice walls block the wind, duh doi.
