A map of millions of galaxies hints: dark energy may be changing its strength. This threatens the Universe with a different end.

New observations of millions of galaxies show: the dark force accelerating the Universe may not be constant. Its behavior is like an engine that sometimes quiets, sometimes speeds up. If so, physics is in for a shake-up.

🎯 Dark energy makes up about 70% of the Universe's mass-energy. If it isn't constant, the cosmos may end in a rip, not a freeze.
