So, what do you think, are we alone in the Universe?
There is a book titled A Universe From Nothing: Why There is Something Rather Than Nothing by an astronomer/astrophysicist named Lawrence Krauss. Old Larry was trying to explain several “simple” concepts in the most rudimentary terms possible. I stuck with it and finished the book and I guess I understood all the words but only about 15 percent of the ideas. It was just plain over my head. But he did mention a few things that I found very interesting.
One of the things he talked about is the huge number of celestial bodies out in space. Larry says there are, give or take, half a billion galaxies in the “known Universe.” (I guess he is not so sure about the “unknown Universe” although he does point to it from time to time) The Milky Way, our galaxy, is just one of that group.
Go out some clear night and look up overhead. That fog-like cloud that you notice smearing the deep black is not a cloud at all. That is the millions of stars in the Milky Way; four hundred million stars, give or take.
Larry notes that each of those half a billion galaxies, like the Milky Way, have from a few hundred million stars to a billion stars inside it. And, he reminds us that we have seen several stars that have planets orbiting them, and we know for sure our sun has nine planets. (Yes, NINE; Pluto was a planet when we hung cardboard planets from the ceiling of Miss Masterson’s fourth grade class, and Pluto will remain a planet. The is the end of that song!)
Who can tell how many of those uncountable stars in those millions of galaxies has a planet or two or NINE spinning around it, just like Earth spinning around the sun?
A planet or two or three, or NINE spinning around some of the millions or billions of stars in each of the 500,000,000 galaxies we know about…..
So, what do you think? Are we alone, or what?
