Nobody said anything about the blogosphere

The geosphere includes all the lifeless things of the universe. The dust, rocks, fireballs, and icycles.

The biosphere refers to those things in the cosmos that are living. It is said that the geosphere gives rise to the biosphere.

The noosphere is the realm of the human mind. It suggests a topography of human reason and belief, complete with the graceful beaches and rocky coastlines in between.
