Ancient ripples in the fabric of the space square off against soot in the galaxy
Gravitational waves from the Big Bang captured worldwide attention in 2014. But then interstellar dust clouds stole
Detection of such waves — ripples in the fabric of space — would be direct evidence for the theory of cosmological inflation, a brief epoch immediately after the Big Bang when the visible universe abruptly swelled to at least 1075 times its initial volume.
In March, astrophysicists thought they had captured their elusive gravitational wave quarry. Researchers with the BICEP2 project reported swirling patterns in the alignment of electromagnetic waves in the cosmic microwave background, or CMB, the primordial light released into the universe about 380,000 years after the Big Bang (
