WebExtract of sample "Dark Energy: Theory and Observations". It is equivalent to vacuum energy in reality since it is the energy density of an unfilled vacuum. The general relativity theory denotes that energy will affect gravity (Wang 76). A cosmological constant is characterized by negative pressure that is equivalent to its energy density. WebUsing this comparison between theory and observation, no evidence was found that gravity is different from Einstein's theory on scales larger than 130 million light years. This limit corresponds to a hundred-fold improvement on the bounds of the modified gravitational force's range that can be set without using the cluster data.
