BIG DEAL!

The Universe is very big! All I have to do is look up at night to see that is a true statement.
I read an article in the Deseret News of Tuesday, November 5, 2013 with the headline:

Study: 8.8 billion Earth-size, just-right planets.

What the authors were discussing was the estimate that in our Milky Way galaxy there are at least 8.8 billion planets orbiting stars of the same magnitude as our sun that are also located in the Goldilocks zone (not too hot and not to cold for life). They also mentioned that there are planets orbiting larger and smaller stars than the sun that also fit into the Goldilocks zone of that star. Add them all together and you get about 40 billion life- compatible planets. 

I then did an internet search to find out how many galaxies are estimated in the universe. That estimated figure was between 200 and 500 billion. Our Milky Way is of medium large size, meaning there are larger and smaller galaxies. Just for fun I multiplied 500 billion galaxies with 40 billion planets and got a figure of   2 x10²² planets (20,000,000,000,000,000,000,000) with life supporting capabilities. 

THE UNIVERSE IS VERY BIG!!!
