I think it's cool that this site educates people about astronomy, and people who read it every day over time end up understanding a whole lot more about the universe. Part of that involves debunking people's misconceptions. The egg balancing-on-the-equinox trick is one of those. The preferred method...

Great job, both of you, on answering the questions! I'll expand a little bit more on the last one. The earth's spin axis precesses over time just like a spinning top does. Only instead of the pull downward of gravity on the spinning top, the forces that cause this motion of the Earth are tidal force...

Enjoying the course
I'm enjoying the course a lot! Thanks for making it free and online. I think all courses should be like this, to the extent possible. I'd expect all humans to be interested in this course just to understand a little more about the neighborhood we live in, the universe in which we find ourselves. Is ...
