An intriguing topic capturing significant media attention is a recent study suggesting that dark energy may not exist. This claim revisits foundational beliefs about the universe's expansion rate, previously thought to accelerate due to dark energy. Dr. Smethurst notes that headlines like “dark energy doesn’t actually exist” are sensationalized interpretations of the study. The study asserts an alternate model called Timescape cosmology, which posits that the universe may not be homogeneous, challenging the validity of dark energy.
