One Billion Years
July 12th, 2008In about a billion years, more or less, our solar primary will quite likely be somewhat larger in diameter and probably somewhat cooler. How this may change surface conditions on this planet is unclear, mainly because the sequence and timing of the changes is uncertain as are their effects on the orbits of the planets. Too, the Moon isn’t going to be a satellite of Earth forever.
And it’s interesting: the same gravitational tidal forces that are ever-so-slowly imparting more energy to the moon also cause the Earth’s surface to shift toward and away from the Moon by several feet every day–almost entirely unnoticed.
I think I saw an article recently that described a (statistical) connection between earthquakes in locales so widely seperated that there shouldn’t be any connection: and yet, there does does seem to be. Probably there’s a correlation, also, between likelihood of seismic events and lunar periodicity.
That is all.
