Why does the Earth h keep spinning?
You know the Earth revolves around the sun and so do the other planets. What manner of physics keeps it going? If you think about it, the standard notion of applying effort to create motion is interesting but it doesn’t work here. The planets are spinning at a more or less constant rate. Where is the force that keeps them going. Perhaps it will make more sense after reading the book Zhuan Falun. It’s a really good book.
Now, one problem that human beings face, besides trying to figure out astrophysics is how to conquer the dreaded gum disease. Perhaps a hydrofloss will help with that. You can try one out.
