Review: A Universe From Nothing by Lawrence Krauss

I just finished “A Universe From Nothing,” by Lawrence Krauss. I found it intensely interesting and enlightening. From a purely scientific perspective, I found it engrossing and understandable, even for a lay-person like myself. There were definitely some points that I did not completely understand, but it helped me to also watch his lecture about this topic online for clarification.

Happy Carl Sagan Day!

Today is Carl Sagan Day.  A day we remember a great mind and popularizer of science.  Carl has been a major influence on my life and my interest in science, and I never knew much of him until he had already passed.  I urge you all to watch his PBS series, Cosmos.  Search youtube for Carl Sagan, and enjoy.  Celebrate his life with me.  We miss you, Carl.

Our Place in the Universe

Delusions of Grandeur

Humans have the amazing inclination to feel like we are the most important thing in the universe.  In the not so distant past, nearly everyone thought our solar system was all there was to the cosmos.  Not only that, but they also largely believed that the Sun and planets all revolved around the Earth.  We have since learned that the Earth revolves around the Sun (with all the other planets in our solar system), and our entire solar system revolves around the center of our own Milky Way galaxy.  In fact, up until as recently as the 1920's, astronomers were under the impression that our immense galaxy was all that existed.
