In 2009, the European Space Agency launched a satellite to search for “gravitational waves” in space/time. The hypothetical waves should be observable in the luminous, radioactive afterglow of the Big Bang known as cosmic microwave background — aka CMB, aka that stuff that helps make the white noise on your TV. The discovery of these waves would prove that, after the Big Bang, the universe expanded at speeds faster than light. Which is fast.
According to Science, the project may not be finished until 2012. But, in the meantime, we can revel in the beauty of universe-wide CMB pictures.
