Hello everyone! I’m back with another post for Solve it Sunday after missing last week.
I hope you enjoy this one. It was a lot of fun talking through it with some friends, seeing if we could find an answer.
Thanks to the work of Copernicus, Galileo, and may others, we know that the day happens because the world rotates on its axis, while the sun remains (apparently) still. But it is not always wise to blindly believe what you are told.
It would be reasonably straightforward to conduct an experiment that would prove that the Earth is revolving on its axis. You wouldn’t even need to leave the Earth’s surface.
Can you think of one?
