Study confirms Einstein's predictions on gravity while exploring dark energy dynamics

Scientists have confirmed that gravity behaves as Albert Einstein predicted in his 1915 theory of general relativity. This conclusion comes from a study of cosmic structure over the past 11 billion years, using data from the Dark Energy Spectroscopic Instrument. The research indicates that while gravity aligns with Einstein's theory, dark energy may be dynamic and evolving, rather than constant. This finding suggests that the universe's expansion may not accelerate indefinitely. The study involved nearly 6 million galaxies and supports the current standard model of cosmology. The results were published online ahead of peer review and involve over 900 researchers from more than 70 institutions.
