Distances in Space 1.1 Distances to Stars When we look up into the night sky and see all the stars, many of which are suns similar to our own, they look fairly close together. But they’re not really close at … Continue reading
Essential Guide to the EU – Introduction
The New Picture of Space Now more than ever, the exploration of our starry Universe excites the imagination. Never before has space presented so many pathways for research and discovery. New observational tools enable us to “see” formerly-invisible portions of … Continue reading
Essential Guide to the EU – Preface
About This Guide This Guide is intended for anyone who wonders how our Universe really works, and who might be interested in an intriguing and somewhat different point of view. Is the Universe now expanding faster and faster as science … Continue reading
