Scientists released the largest ever three-dimensional map of the universe, proving that it is basically flat and filling in an 11 billion year gap in its history.
“We know both the ancient history of the universe and its recent expansion history fairly well, but there’s a troublesome gap in the middle 11 billion years,” said Dr Kyle Dawson.
Dr Dawson, a cosmologist at the University of Utah, lead the Sloan Digital Sky Survey (SDSS) team which worked for the past five years to fill in that gap.
Their results were produced in an international collaboration with more than 100 astrophysicists taking part in something called the extended Baryon Oscillation Spectroscopic Survey (eBOSS).
The survey captured detailed measurements of more than two million galaxies and quasars, covering 11 billion years of cosmic spacetime.
The map reveals how the structure of the universe is defined by filaments and voids of matter, dating back to when it was just 300,000 years old.
