The Largest Map of the Universe Just Revealed Something Deeply Unsettling About How It Ends

For decades, we thought we knew how the universe ends. The stars would burn out, the galaxies would drift apart, and everything would fade slowly into a cold and endless dark. A quiet, settled ending. We were sure of it. Then we built the largest three-dimensional map of the universe ever made — tens of millions of galaxies, stretching back 11 billion years — to measure the invisible force that controls the fate of everything: dark energy. And the map whispered back something no one was prepared for. Dark energy may not be constant. It may be weakening. And if it is, the ending we wrote for the cosmos could be completely wrong. The universe might not freeze at all. It might one day stop expanding, reverse, and collapse back into a single burning point — the Big Bang, run backward. But the most unsettling part isn't the collapse. It's that we may have just realized we no longer know how everything ends at all. - Credits: DESI NOIRLab NASA ESA: https://www.esa.int/ESA_Multimedia/Vi...
