A study by the University of Provence in Marseille (France), which has been used to measure the geometry pairs of distant galaxies, confirming that the Universe is flat and indicate that dark energy is probably Einstein's cosmological constant.
The rapid expansion of the universe seems to require the existence of dark energy opposes gravity. In principle it is possible to study the cosmic expansion to analyze the distortions imposed on distant structures through the geometry of space-time. In practice, however, no cosmological local movements of astronomical objects have made this difficult test implement.
The researchers, led by Christian Marinoni and Adelina Buzzi, have overcome this problem by applying geometric proof pairs of distant galaxies in orbit. After calibrating the method using pairs of nearby galaxies, the authors found that the apparent geometry of distant pairs requires that the universe is flat. In addition, when data were combined with observations of clusters of galaxies to large scale, the data identify Einstein's cosmological constant, equivalent to a vacuum energy proposal, as the likely explanation for dark energy.
