  • Not sure the point of your comment. The article uses that word, or ither forms of it a bunch, they are not shying away from it. An immigrant is someone who moves TO a country. An emmigrant is someone who moves FROM a country. These are both permanent moves (or intended to be). An expat is someone who LIVES in another country. Formally it means temporarily but I’ve seen it colloquially used for both temp and permanent.

    So “US expats in New Zealand” is precise and inclusive whereas “immigrant” means people from any country who moved permanently. Imprecise and non inclusive.







  • When you push something you push the atoms in the thing. This in turn pushes the adjacent atoms, when push the adjacent atoms all the way down the line. Very much like pushing water in the bathtub, it ripples down the line. The speed at which atoms propogate this ripple is the speed of sound. In air this is roughly 700mph, but as the substance gets harder* it gets faster. For example, aluminum and steel it is about 11,000mph. That’s why there’s a movie trope about putting your ear to the railroad line to hear the train.

    If you are talking about something magically hard then I suppose the speed of sound in that material could approach the speed of light, but still not surpass it. Nothing with mass may travel the speed of light, not even an electron, let alone nuclei.
