Sometimes the earth rotates more quickly (mornings!) and sometimes more slowly (class time!), and these rotational differences are due to what scientists call “lots of stuff.” (These could include icecap thicknesses, magma movements, earth/moon orientations, how Trump feels today, etc.)
Anyway, said scientists believe that next year MAY bring a millisecond delay in the earth’s rotation, which, not only causing JR to send out apologies for any inconvenience, might also trigger (gasp!) EARTHQUAKES! The key point is not to panic, so please unread this if you can. Otherwise, prepare yourselves for refugees streaming across the island from Miyazaki as the Nankai Trough ruptures. Or it could be somewhere else. Or nowhere. It’s just probability, after all. - William
