Telescopes all around the World are daily collecting huge amounts of data from the sky. However, this information must be interpreted before we can say anything about the physics of the cosmos. Therefore it highly depends on the model one uses for the dynamics of the universe. The standard model of modern cosmology says that the universe is both homogeneous and isotropic at large scales. This is clearly not the case in the local neighborhood of our galaxy, and all the way out to superclusters of galaxies. The real universe, rather being inhomogeneous, will automatically have an effect that behaves in the same way as dark energy does. This may alleviate the need for an accelerating universe.Validerat; 20111027 (anonymous
