Alone in the Cosmos - The Chronicle Review - The Chronicle of Higher Education
Our little world has become lost in an immense universe that holds more planets than there are grains in a cubic mile of fine sand. To add insult to injury, the announcement in March by the Bicep2 research group that gravitational waves were generated in the very early universe supports cosmological models in which even the most distant visible galaxies are relatively near neighbors in a possibly infinite universe—a universe that is, itself, just one component of an unimaginably vast multiverse. While half a millennium ago we thought ourselves the center of the cosmos, in the modern conception of the universe we have become less significant than microbes on a mote of dust.
