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 traveling 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.
