A Billion Other Biospheres

In ‘What is Biospheric Communion’ I ask you to imagine a billion biospheres. This may seem extravagant but consider the following:

The universe may be a big, cold, empty place but in amongst all of that empty space there is also a very large number of worlds. In the last decade, while the semanticists at the IAU argued over whether there are eight or nine planets, actual astronomers have begun mapping out the trillions worlds orbiting our sun. The Oort cloud is out there and it is made up of a trillion worlds each at least 1 km in diameter. The public’s imagination has yet to assimilate the opulence of the outer solar system. There are roughly one thousand worlds out there for every man, woman and child on Earth. That is before we travel to other stars. There are more than 100 billion stars in the Milky way, each potentially with a trillion worlds. There a most probably 100 billion trillion worlds in the galaxy. And there are 100 billion galaxies in the universe, so there are likely 10 thousand billion billion trillion worlds in the universe. That is 10 000 000 000 000 000 000 000 000 000 000 000 worlds. That a billion of those worlds would have a biosphere seems a conservative estimate; after all, that is only 1 world in every ten thousand billion trillion.
