Telescopes cannot see gravity, but they can see the effects of gravity. What the Harvard team spotted was the telltale signature that primordial gravitational waves imprinted on the faint light left over from the big bang. This ancient afterglow fills the universe, and is known as the cosmic microwave background. The inflation theory suggests that the fluctuations that are seen in the background radiation, and which are the seeds for galaxy formation, are generated by quantum irregularities when the universe was expanding on a timescale of 10-36 seconds and the entire observable universe was smaller than a tennis ball.
