An international team of astronomers says new data show energy output measured across more than 200,000 galaxies is only about half as strong as it was 2 billion years ago. Scientists point to this latest study as further evidence that the universe is slowly dying.

 

John Beacom, a physicist and astronomer at Ohio State University, told NPR that before this comprehensive study, there was always the possibility that scientists didn't have the full picture of how the universe was changing. "This pretty much closes the case: Yes, it's coming to an end," he says.
