The Hundredth Monkey Phenomenon

This quote just blows my mind:

Our entire solar system—planets and all—sits inside a gargantuan bubble of gas about four times wider than the orbit of Neptune. The sun is responsible. It blows the bubble by means of the solar wind. Astronomers call the bubble itself “the heliosphere” and its outer membrane “the heliosheath.”
