One final important point to make about working with the Moon, is that it helps to realise that all things have the need for both generating and clearing. This means that both aspects of the lunar cycle can be used to your advantage for any particular issue or project. For example, if you are looking at having a huge clean-up at home, you could plan and design everything, including any furniture/room arrangement changes, during the waxing time. This is your time for creating new looks and new ways to live. You could then go on to do the cleaning up work during the Waning period. The perfect time to let go of the old, so that the new designs can take their place. A billion years ago, our Moon was closer to Earth than it is now. As a result, it appeared to be a much larger object in the sky. During that ancient era, if human beings had been around to witness such a sight, it would have been possible to see the entire Moon--not merely the one near side face that we see now. A billion years ago, it took our Moon only twenty days to orbit our planet, and Earth's own day was considerably shorter--only eighteen hours long. Stupendous, almost unimaginably enormous tides, that were more than a kilometer in height, would ebb and flow every few hours. However, things changed, as the lunar orbit around our primordial planet grew ever wider and wider. Annually, Earth's Moon moves about 1.6 inches farther out into space. Currently, the lunar rate of rotation, as well as the time it takes to circle our planet, are the same. Dr. Soderblom calculated the gravity signatures both in and around 1,200 craters that had been excavated by impacting objects on the lunar far side. He then went on to compare the gravity within each crater with the gravity of the surrounding terrain. Dr. Soderblom did this in order to determine whether an impact increased or decreased the local porosity.
