Is Dark Energy Just a Cosmic Time Warp?

In a universe-shaking twist, recent studies of over 1,500 supernovae challenge dark energy's existence. Timescape cosmology steps into the spotlight, suggesting uneven time flow across cosmic regions mimics accelerating expansion. This nifty theory throws a wrench into the standard ΛCDM model and its 13.8-billion-year timeline. With the Euclid mission and Nancy Grace Roman Telescope gearing up, 2025 could unveil whether our cosmos is just a tad more 'lumpy' than we thought.
