I've heard that a lie makes it around the world while the truth is pulling on its trousers. Why isn't the naked truth allowed to go naked in public?

Why are only lies allowed to get away with pubic streaking?

ELI5 why light slows down in a transparent medium

Most explanations I've seen say that the light interacts with the atoms of the medium, resulting in absorbtion and re-emission. That makes sense for translucent media, but I don't understand why it doesn't produce so much scattering that nothing would be transparent. Other explanations I've seen treat light as a classical wave. What is the quantum theoretic explanation for why light that is not scattered by a transparent medium is slowed by that medium?

Why do people believe scientists when they say things weigh less on the moon? If you send a balance scale set and a 250 gram test mass to the moon, doesn't the test mass still weigh 250 grams?
