Earth's gravitational pull is massaging the moon, opening up faults in the lunar crust, researchers say. Just as the moon's gravitational pull causes seas and lakes to rise and fall as tides on Earth, the Earth exerts tidal forces on the moon. Scientists have known this for a while, but now they've found that Earth's pull actually opens up faults on the moon.
Yes, it's weak enough to keep the solar system from flying apart and ensuring mass extinctions take place every 70 odd million years. It holds the Sun itself together and best of all, causes apples to fall from trees. Life would be impossible without it's unique set of parameters . . . whatever they may be.
