This mass discrepancy has been confirmed by observations of gravitational lensing, the bending of light predicted by Einstein's theory of general relativity. Until about thirty years ago, astronomers thought that the universe was composed almost entirely of this "baryonic matter", ordinary atoms. WMAP strongly constrains dark energy and geometry of the universe. to only 5.9 protons per cubic meter. when ripples in the very fabric of space may have been created. The main attraction of the cosmological constant term is that it significantly improves "greatest mistake". A cosmological constant term added to the standard model Big Bang theory leads to a model that appears to be consistent with the observed large-scale distribution of galaxies and clusters, with WMAP's measurements of cosmic microwave background fluctuations, and with the observed properties of X-ray clusters. practical for astronomers to observe very bright rare stars called supernova in an effort around hot and cold spots follows the pattern expected in the standard
to measure how much the universal expansion has slowed over the last few billion years.

It is also able to determine some of the properties of the non-baryonic matter: the interactions of the non-baryonic matter with itself, its mass and its interactions with ordinary matter all affect the details of the cosmic microwave background fluctuation spectrum. Read the original article.
Models which preserve strong energy condition are to the top right of the dotted lines. If the maps from eBOSS were the first to explore a previously missing gap of 11 billion years of our history, the new generation of telescopes will make a high-resolution version of the same period of time. We are not showing the full region allowed by supernova constraints because much of it is ruled out by WMAP observations. Your opinions are important to us. (Tonry et al. 2004), we combine the data on 230 supernovae published by Tonry et al. You, this computer, the air we breathe, and the distant stars are all made up of protons, neutrons and electrons. expansion. 64 x 90 JPG (2 KB) Prior to the release of the new five-year data, WMAP already had made a pair of landmark finds. (We have varied some of the parameters individually, e.g. We are carrying out a detailed study where variation of most of these parameters is allowed and we also bring in more constraints (Jassal, Bagla & Padmanabhan, in preparation). This effect becomes increasingly important as w approaches zero, leading to suppression of perturbations in matter (Benabed & Bernardeau 2001; Amendola 2003; DeDeo et al. WMAP and Dark Matter / Dark energy. This energy, distinct from dark matter, is responsible for the present-day acceleration of the universal expansion.
