Now that is way to large a subject for one blog, it would take a series of blogs to answer that question. So, I am going to narrow it down to things pertaining to astronomy. . . bet you would never have guessed astronomy (grin). First question is: How did the Tropic of Cancer and the Tropic of Capricorn get their names? Do you know? I didn't know the correct answer, but figured it has to do with the constellations with those names. Well, I figured correctly but why were they named that?
From a little reading from my newest edition of Astronomy, I found out that way, way back several thousand years ago, the sun was in front of those two constellations. I bet you guessed that the sun was in front of Cancer at the summer solstice and in front of Capricorn at the winter solstice. Over time our sun and solar system moved through space and the perspective, and thus positions of other objects changed also. Not only does the Earth travel around the sun, the solar system travels around tucked in an arm of the Milky Way spiral galaxy, and the galaxy travels through our universe and I am sure our universe travels through something greater and larger. Everything is in motion. Not only the extremely large, but also the extremely small. I just try to sit still and watch everything go by, but no, I actually rock most of the time in my recliner/rocker.
OK, I lied to you at the start. I said "first question is", but I didn't post a second or third question. Maybe I will do that later on down the road. Now, you all have a great day as we wait for the summer solstice, you hear?
