[quote:Dr. Astro:MV8yMjY3MjIyXzM4NTQ4NDMzX0M4RDlFRTVF] Earth has greater angular momentum due to having greater mass than the moon. Furthermore, due to the earth's distance from the sun, the solar tidal force is less than half the magnitude of the moon's tidal force upon the earth. Earth's rotation is slowing gradually, primarily due to lunar tidal acceleration, not the solar tidal force (therefore the equilibrium point is a rotational rate closer to once per month than once per year). As a result the moon converts our angular momentum into orbital momentum, causing it to slowly increase its orbital radius. These forces are very gradual and because of our greater angular momentum we are not yet tidally locked to the moon and won't be for billions of years. [/quote]

so simple test question for those with intuition
if the moon is in resonance lock down with the earth in such a way that we always see the same side of the moon
why should be any different with the sun and the earth?
what if the earth and sun are in resonance lock down
and we always see the same side of the sun
then, how would we know what lies behind the dark side of the sun?
should we believe strangers that look nice and say that all is well?
is it any different with how our dear parents teach us not to accept candies from 'well-intended' strangers? :)
