I began to think about the preparation and timing, planning and organizing, the countless hours of testing gear for a single moment lasting two minutes, where the Moon and Sun aligned.  I was in the right place, at the right time. Solar Eclipses are rare, and it’s mostly because only a narrow band of land on Earth, usually around 100 Km wide, experiences such an event at any one time.  And with...

The universe is so large and so vast, we may be in a local region where the laws of Physics are set, and our laws may be different from a distinct region somewhere else in the universe. The good news is that we can make predictions based on our understanding of physics. And with our powerful telescopes that allow us to view a variety of...
