Instead, the report’s authors suggest that standard models of the universe fail to account for its shifting structure and introduce dark energy without needing to.
Dr László Dobos, co-author of the paper and a researcher at Eötvös Loránd University, said the study questioned the validity of scientists’ solutions to Einstein’s theory of general relativity:
“Our findings rely on a mathematical conjecture which permits the differential expansion of space, consistent with general relativity, and they show how the formation of complex structures of matter affects the expansion. These issues were previously swept under the rug but taking them into account can explain the acceleration without the need for dark energy.”
Previous models have relied on the idea that the universe expands at the same rate, but the study’s authors have dropped that assumption.
But despite accounting for different regions of the universe expanding at different rates, the average rate is accelerating and in line with observations.
If its findings are backed up, the study threatens to overhaul many theoretical physicists’ understanding of the universe.
It’s not the first study to challenge the existence of dark energy.
Back in October, researchers at Oxford University questioned the idea that the universe is expanding at an accelerating rate.

Echo 1, a spherical balloon with a metalized skin, was launched by NASA on 12th August 1960. Once in orbit the balloon was inflated until it reached its intended diameter of 30 metres and it was then used as a reflector to bounce radio signals across the oceans.
