Title: Is there a point on the earth's poles where you rotate as you stand?
Post by: scientizscht on 31/10/2019 20:07:37

Hello

Is there a point on the earth's poles where you rotate as you stand?

At the point where the axis of rotation of the earth crosses its surface?

Or it doesn't work like that?

Thanks!

That's pretty much the definition of the pole.

So such point exists? Are there any videos?

The Earth's axis wobbles during the year, so you could say that there is a particular spot which is the Earth's axis on one day, but you would need to take a small step to be on the correct spot for the next day...

What would you expect the video to show?

Perhaps a pole sticking out of the ground? Video would show it moving  :)
I think @Halc was pointing the camera in the wrong direction  >:(
