DESI has made the largest 3D map of our universe to date. Earth is at the centre of this thin slice of the full map. In the magnified section, it is easy to see the underlying structure of matter in our Universe.DESI has made the largest 3D map of our universe to date.

The results confirm that the expansion of the universe is speeding up, they added. However, the findings have also raised the tantalising possibility that dark energy – a mysterious, repulsive force that drives the process – is not constant throughout time as has previously been suggested. “Now all of that goes out the window and essentially we have to start from scratch, and that means revising our understanding of basic physics, our understanding of the big bang itself, and our understanding of the long-range forecast for the universe,” he said, adding that the new hints left open the possibility that the universe might undergo a “big crunch”.
