Dark Energy May Not Exist: Something Stranger Might Explain The Universe

The Universe might not be expanding under the spell of a mysterious “dark energy” after all. Instead, the answer could lie in time itself—bubbles of space where clocks tick differently. New research suggests these variations in time, shaped by gravity’s uneven pull, might explain why distant galaxies seem to flee faster than expected. By analyzing over 1,500 supernovae, scientists found the timescape model, which accounts for this cosmic “lumpiness,” may outshine our standard theories. It’s a tantalizing nudge to rethink how we see time, space, and everything in between.
