  "description": "Measurements of the distances to type Ia supernovae have produced strong evidence that the expansion of the Universe is accelerating, implying the existence of a nearly uniform component of dark energy with negative pressure. We show that constraints to this mysterious component based upon large-scale structure nicely complement the SN Ia data, and that together they require ${$\u03a9${}}_{X}\\phantom{\\rule{0ex}{0ex}}=\\phantom{\\rule{0ex}{0ex}}{$\u03c1${}}_{X}/{$\u03c1${}}_{\\mathrm{crit}}$\ud835\udfc4${}(0.6,0.7)$ and ${w\\phantom{\\rule{0ex}{0ex}}=\\phantom{\\rule{0ex}{0ex}}p}_{X}/{$\u03c1${}}_{X}<$-${}0.6$ ( $95%$ C.L.), for the favored flat Universe. Other cosmological data support this conclusion. The simplest explanation, a cosmological constant, is consistent with this, while some of the other possibilities are not.",
