Dark energy, the mysterious force powering the expansion of the universe, appears to be weakening over time, according to a major cosmological survey that has thrown the laws of modern physics into doubt. Ian Sample tells Madeleine Finlay how this new finding could shed light on the ultimate fate of the cosmos, and Saul Perlmutter, who won a Nobel prize for his work proving the universe is expanding, describes how the new development could upend assumptions about how this mysterious force operatesSupport the Guardian: theguardian.com/sciencepod Continue reading...

Findings could open up possibility the universe will end in a reverse big bang or ‘big crunch’, say cosmologistsExplainer: Is dark energy destined to dominate the universe?Dark energy, the mysterious force powering the expansion of the universe, appears to be weakening, according to a survey that could “overthrow” scientists’ current understanding of the fate of the cosmos.If confirmed, the results from the dark energy spectroscopic instrument (Desi) team at the Kitt Peak National Observatory in Arizona would have profound implications for theories about the evolution of the universe, opening up the possibility that its current expansion could eventually go into reverse in a “big crunch”.

4 w. ago Is dark energy destined to dominate the universe and lead to the ‘big crunch’?

New universes may emerge in due course, says scientist at Dark Energy Spectroscopic Instrument in ArizonaDark energy: mysterious cosmic force appears to be weakening, say scientistsSince the big bang, a cosmic battle has been under way between matter (both dark matter and ordinary) and dark energy.The gravitational force that draws massive objects such as galaxies towards each other works against the expansion of the universe. But astronomical observations show that the universe’s expansion has, oddly, been speeding up. This led scientists to conclude that dark energy, a mysterious force acting as a sort of anti-gravity, permeates the entirety of space. And dark energy appeared to be at a significant advantage in the cosmic tug of war. Continue reading...

Data from European Space Agency’s mission has allowed researchers to create detailed catalogue of 380,000 galaxiesAstronomers are predicting an “avalanche of discoveries” after the first major release of observations from a European space telescope built to study the mysterious dark matter and dark energy that comprise the bulk of the universe.The European Space Agency’s Euclid mission has captured images of 26m galaxies, covering 10bn years of cosmic history. They give researchers unprecedented insight into the forces that shape the cosmos and the galaxies it holds. Continue reading...
