what I've learn from it that these cosmologist wanted to reassure about what Albert Einstein made at it was the study of gravity well they retraced his steps from outerspace to see if its accurate and it was which is pretty impressive from not having modern technology now and they measured the gravity around them pretty much cosmic expansion it becomes hubble tension from the measurements which is not good so how they fix it was by altering the relationship between matter and spacetime, and studied how they can constrain deviations from the prediction of General Relativity. They said that the results were promising but we're still a long way off a solution.
