Feel free to reply to any comment by clicking the "Reply" button.The Universe at 93 billion light years in diameter means that we can only see 13.8 billion light years of it. Light and the speed of light is what allows us to see and calculate how much we can see and measure. This seems to not make sense as we have been told for years that nothing travels faster than light, except space itself. So the space of the Universe is larger than what we can see. As the Universe expands we will see less and less of it as it is expanding faster than we can see it. Sounds confusing but light is an object which has to follow the rules of Relativity, space itself can move faster than the speed of light, it is not an object within space-time, it is space-time.

Posted by starwatcher-alI missed the early phases of the eclipse but the clouds mostly left during totality. All in all a great eclipse. Next one is Nov. 8-22
