We are all here to learn, everyone has some hidden virtue:
The sun cannot be stationary, fixed (as the heliocentrists say! Has v sholom ) AND at the same time be the concern of Bichas Hahammah for having moved one complete enormous circuit in the total time of 28 Jewish -calculated years through the sky ! Heliocentric means the sun is fixed and at the center , has v sholom. Maybe this will help:
According to Birchas Hahammah , the sun takes 28 complete Jewish – calculated years to move around the sky to get back to the exact same place that Hashem put it when He originally created the sun. So the 28 year cycle is based on the moon months – chodoshim, and the seasonal changes across 365.25 days and is NOT based on what the secular world understands to be an imaginary circuit of the earth around the sun.
