| Apr 24, 2018 at 0:57 | comment | added | Glen_b | Even with physics you must be careful; what our best models say does change over time. An exact equality under Newtonian physics turns out in particular situations not to quite work (the null in a Newtonian model of the situation is not exactly true and eventually we can identify situations where we can spot it). Einstein comes along and we then get agreement to as much accuracy as we can muster - but we must remember that was once true for Newton. Or we have a conservation law that we can eventually see doesn't quite hold and eventually we refine it to a broader law that does seem to hold. | |

Say, anything I do on Earth can only begin to affect the Sun in 8 minutes from now. The effect of me clapping hands right now on the position of Sun spots as recorded by the Sun telescope at that same moment as I am clapping is exactly zero. | |

| Dec 5, 2013 at 23:36 | comment | added | whuber♦ | +1 Minor quibble: many null hypotheses are indeed exactly true, especially in one-sided tests and in other situations with composite nulls. | |
