I went on my evening walk re-listening to an astronomy lecture “Big Bang 2” that covered a lot of stuff previously mentioned and went into the structure of the universe (as seen by a fourth dimensional person). Depending on the mass of the universe which is determined by Omega (that is the density of space and the shape of space). If omega is greater or lesser than one the universe will either expand forever or collapse– one type of universe is the Positive curvature like a balloon that is called a “closed universe” has an omega of more than one and will collapse into the “big crunch”- then a flat universe that is open, infinite with no boundaries and expands forever- finally a saddle-shaped one that is “open”, has an omega less than one, is infinite and unbounded and the universe will expand forever. It is presently believed that our universe has an omega of 1 and is flat. The Professor talked about black energy that makes up most of the known universe. There was a lot more! When I got back from my walk Fat Cat was waiting at the back gate for me!
Read on someone’s astronomy blog that there is a nice binary star in Cygnus located at the Swan’s head called Albireo that has a yellow-white star and a blue one. I just had to get the telescope out to give it a look-see! The dang binary was at my zenith (straight up) and it was hard to get my telescope that is on a tripod to view it. I ended up putting it on a table and tilting it back on one leg to be able to observe this binary star system, but it was well worth it! Just as beautiful as Algieba in the constellation on Leo!
