Our understanding of the universe remains solid, say astronomers whose new study has found the expansion of the universe is still accelerating as previously found.
In late 2025, a team of astronomers shocked the space community with claims that the evidence of dark energy – a mysterious force that pushes the cosmos apart – was weakening such that the expansion is no longer accelerating.
They suggested the methods used to measure the universe’s expansion using supernovae, or exploding stars, were fundamentally flawed.
But a new study led by the University of Southampton, which re-evaluated the data, has found that the universe is behaving exactly as expected.
