Back in the early 1990s I corresponded with astronomer William Tifft at the
U of Ariz. (Flagstaff). Seems he had possibly found evidence of
quantization of the red shift. He put me in touch with physicist Ari Lehto
who had proposed a theory of dimensional-binding which included the concept
of 3D time. I may even still have a copy of his paper. At time time, he
was with the Univ of Oulu in Finland, but later transferred to a state
university somewhere. Bill Tifft is now Emeritus Professor of Astronomy at
the U of A.
anyone is truly interested in experimental observations that suggest 3D
time, Ari Lehto and Bill Tifft are the guys to go to.
