    Abstract: This study re-evaluates the fundamental principles of Einstein's General Relativity, particularly its cornerstone assumption of a constant speed of light in a vacuum, in light of experimental evidence demonstrating significant light deceleration. The pivotal 2006 experiment by Lene Hau and her team, achieving near-zero light speed in a Bose-Einstei... Show More

    Abstract: Solar eclipses provide unique opportunities to study how the ionosphere responds to rapid changes in the ionization rate. The partial solar eclipse of January 26, 2009, and the partial solar eclipse of March 20, 2015, offered opportunities to understand ionospheric electron density variations along the annularity path during solar minimum and geoma...
