Input (English): Gliner and Zeldovich are credited with the modern interpretation, in which it contributes its value times the metric tensor divided by 8 pi times the gravitational constant to the energy-momentum tensor. In the Friedmann equation, it appears on the right-hand side divided by three, and measurements from WMAP have suggested that its energy density is approximately 0.7 times the critical density. Its equation of state parameter w is -1, giving a negative effective pressure that tends to accelerate the expansion of the Universe. FTP name this simple form of dark energy, rejected by Einstein as his "greatest mistake. "
Output (English): Science
