Human physicists necessarily spend all their time in these conditions and think of them as ordinary. The physics of these ordinary conditions has already been thoroughly studied, which makes them now familiar and boring. Instead physicists get excited to study more extreme conditions, most of which would be quickly lethal to humans — anything from the event horizons of black holes to the vacuum of space, to volumes where charged particles travelling near the speed of light are forced to collide, and many, many things in between. Thus, extreme conditions are very dangerous for most organisms. Even for especially resilient organisms, such as tardigrades, there is a point past which they will [https://what-if.xkcd.com/141/ stop being biology and start being physics], in which case their resilience will not save them. Thus if a physicist is excited about something, it likely exists in circumstances where your own existence — as well as other life — would meet an end. One (partial) exception is particle beams; {{w|Anatoli Bugorski|people can stick their heads in particle beams and survive — but not unscathed}}. Also, physicists used to be excited about (particles produced by) cosmic rays before they had powerful accelerators. |
