Science is often looked at as a solid body of knowledge. It is far from that. Science is often mistaken in what it supposes, since it operates from the paradigm of the society and not all things have been found out or accounted for yet; therefore the paradigm often doesn't know what to look for and so doesn't see what is there properly, or at all. We used to think that all the planets and the Sun revolved around the earth. Copernicus dared to contradict that theory, although he may not have been the only one to know it wasn't true just the bravest (or the most foolhardy). It was Galileo and his telescope which proved that Copernicus was right. They both agreed that the earth and the other planets of our solar system orbit the sun. It has also become increasingly clear that the sun moves through the galaxy while the planets are orbiting it. Nassim Harramein's video on Youtube is a good reference for what is actually happening - the sun is moving like a sine wave and spiraling through space, which means all the planets are spiraling with it. That puts a bit of a different spin on things, if you will excuse the pun.
All that to say that, if the inner planets, which are closer, exert more of a personal force on us, Mercury, Venus, Mars, Jupiter, and Saturn, than the outer planets more of a generational force, since they are more slow moving. Neptune, Uranus, and Pluto or Chiron exert either an unconscious pull on an individual or an overt pull that moves a generation or a time to action. The French Revolution on the other hand occurred when Uranus was in Leo, Neptune in Libra, and Pluto in Aquarius. Uranus is the planet of transformation and in Leo it rules authority; It seems self-explanatory. Neptune is the dreamy planet of illusions which was in Libra, ruling justice or balance. There were many illusory ideas about justice at that time. Pluto the planet of regeneration was in Aquarius, which is a more egalitarian, humanitarian sign. Ultimately the French Revolution lead to a more egalitarian form of government, however, Pluto being a slow-moving planet it took time. So what will happen for us? Pluto went into Capricorn (material acquisition) in 2008 and the U.S. Financial Crisis hit. It is a time when we can reorganize our financial economy. Have we? Pluto stays twelve years in the sign which will put it at 2020 when it leaves to go into Aquarius. (Did I mention that the French Revolution happened when Pluto was in Aquarius?) Neptune is in Pisces, which allows for intuition and insight, presumably to give us a new vision of how to reform things. And Uranus is in Aries, Aries being new beginnings. Let's hope we get it figured out soon!
