What modulates our Sun? The majority of science work on the principle that the Sun is self modulating and each solar cycle is a product of a random number generator. There are others that suspect the Sun is modulated by the planets with a special emphasis on Uranus & Neptune. Thanks to Carl Smith who has recently left us we have new knowledge that significantly adds to Jose, Landscheidt & Charvàtovà's work.

Ian Wilson's Evolving Research.

Ian Wilson has been slowly developing his theory on spin orbit coupling whereby the planets affect the rotation rate of the Sun. Ian is an Australian Astrophysicist that has published many papers and also posts his theories on his blog.

Recently Ian has been producing new data that supports a tidal and gravity function that correlates with the sunspot cycle length observed over the past 400 years.
