General relativity is a theory of gravity developed by Albert Einstein that explains how massive objects interact with each other and how they affect the fabric of space and time.
General relativity predicts that the expansion of the universe should be slowing down due to the gravitational pull of matter. However, observations have shown that the expansion is actually accelerating, leading scientists to theorize the existence of dark energy, which counteracts gravity and causes the expansion to accelerate.
Several lines of evidence, including observations of distant supernovae, the cosmic microwave background, and the large-scale structure of the universe, all support the existence of dark energy and its role in the accelerated expansion of the universe.
Dark energy makes up about 70% of the total energy in the universe and is responsible for the accelerated expansion of the universe. It also plays a role in the formation and evolution of galaxies and large-scale structures in the universe.
Currently, there is no widely accepted theory that can fully reconcile general relativity and dark energy. Scientists are still working to understand the nature of dark energy and how it fits into our current understanding of gravity.
