A common criticism of the Bohr model was that orbiting electrons should produce EM waves, lose energy, and therefore eventually spiral towards the nucleus. Similarly, if gravitational waves exist, won't the Earth/other planets fall into the Sun?

Why do we use Relative Humidity in all the weather reports? Surely how dry it feels is related to the Absolute Humidity? Or if how dry we feel is because of Relative Humidity, why?

A person using a hang-glider can dive down to gain speed and then pull up to end up higher than what he was before he dived. Is this true? If it is, how doesn't it violate laws of conservation of energy?

I realise that how humid it feels is based on relative humidity, not absolute humidity. But what about how dry your skin feels, when it chaps/peels/etc? Is that based on absolute, or relative humidity?

You have a practically infinite budget and a time limit of one year to make the best sword humans can make right now. What goes into it?
