Hi Danat, just mention the word 'equilibrium', that, and we see everything in extreme slow motion on our time scale :-) we're living in between the seconds of the universe
and its more than a small window for eclipses - ( as it is there is already differences in eclipses, due to moon's apogee and perigee and inbetween affect on apparent size - also the sun apparent size varies a little due to earths slightly ecliptic/egg shaped orbit ) it is many thousands of years since and into the future, natures grandest show still works, i think at least 4000 years in future from memory?
