Albert Einstein’s prediction about how gravity behaves has been tested on a cosmic scale. Albert Einstein’s prediction about how gravity behaves has been supported by an international team of researchers who studied how the force acts on cosmic scales.
Dark Energy Spectroscopic Instrument (DESI) researchers found that the way galaxies cluster is consistent with our standard model of gravity and the predictions from Einstein’s theory of General Relativity.
A complex analysis of the first year of data from DESI provides one of the most stringent tests yet of General Relativity and how gravity behaves at cosmic scales.
Looking at galaxies and how they cluster throughout time reveals how cosmic structure grows, which lets DESI test theories of modified gravity – an alternative explanation for our universe’s accelerating expansion.
DESI is managed by the US Department of Energy’s (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab). UK involvement in DESI includes the University of Portsmouth, Durham University, and UCL as full member institutions, together with individual researchers at the universities of Cambridge, Edinburgh, St Andrews, Sussex, and Warwick.
