2012 - Science Or Superstition?/WC/3
We know that all orbits conform to Kepler's laws - they move in great ellipses rather than circles. That means the bodies speed up when the two masses get closer to each other, when the gravitation is stronger, and they slow down when they get farther away from each other.
So if precession is the observable of a solar system in motion around another star, it too, would have to obey Kepler's laws - it would speed up and slow down. Now, we have really good scientific data for the last hundred years going back to the great Simon Newcomb, the number one astronomer in the U.S. in the year 1900. He kept precises records of precession and noticed that it's speeding up every year - exponentially. So he actually added a constant to the precession equation - Newcomb's constant, we call it nowadays. And even since then, the precession has sped up above the constant rate.
But we've taken the Vedic view that it's caused by an orbit that is 24,000 years, and therefore, if precession actually measures 26,000 years, we must be in the slow part of the orbit - far from the other star right now. We plotted on a curve what the precession rate would be over this last 100 years and we came out with the exact curve that we see historically, and from that we are able to predict that the precession rate will continue to accelerate year after year until we reach periapsis.
