Ideas, Inventions And Innovations : New View of Nature's Oldest Light Suggest Universe Is 13.77 Billion Years Old

Ideas, Inventions And Innovations New View of Nature’s Oldest Light Suggest Universe Is 13.77 Billion Years Old From an observatory high above Chile’s Atacama Desert, astronomers have taken a new look at the oldest light in the universe. Their observations, plus a bit of cosmic geometry, suggest that the universe is 13.77 billion years old – give or take 40 million years. A Cornell researcher co-authored one of two papers about the findings, which add a fresh twist to an ongoing debate in the astrophysics community. The new estimate, using data gathered at the National Science Foundation’s Atacama Cosmology Telescope (ACT), matches the one provided by the standard model of the universe, as well as measurements of the same light made by the European Space Agency’s Planck satellite, which measured remnants of the Big Bang from 2009 to ’13.
