But it may be the only defense, however partial it may be, that Kaczynski's attorneys have. FBI agents uncovered a trove of evidence in his Montana cabin, including virtual signed confessions and a signature completed bomb.
1 Whenever the Moon, Earth and Sun are aligned, the gravitational pull of the sun adds to that of the moon causing maximum tides.  Spring tides happen when the sun and moon are on the same side of the earth (New Moon) or when the sun and moon are on opposite sides of the earth (Full Moon).
This relationship means that, though the Sun is much more massive than the Moon, the Moon has a far greater effect on the Earthâs tides because it is very much closer. At any time, the gravitational pull on the oceans is greatest on the side of the Earth that is facing the Moon. This causes a bulging of water towards the Moon, which is experienced as a high tide on Earthâs coastlines. Meanwhile, on the far side of the planet, there is a second bulge.
