In General > s.a. cosmological
constant and models;
cosmology [future]; varying
constants.
* Idea: A component of
the content
of the universe with negative pressure, which accelerates its expansion; May
be a cosmological contant or may be dynamical; The name seems to have been
introduced by M Turner.
* Status: 2003, Various
methods give –1.22 < w < –0.78 at 95% c.l.; 2004–2005,
Analysis still favors a cosmological constant – other models give as good
a fit, but are not
as simple (1-parameter) or physically motivated – with quintessence a second
possibility; 2006, Evidence from Brad Schaefer's analysis of distant GRBs that
it may be changing; 2006, Evidence from supernovas at z = 1 consistent
with constant
dark energy; 2007, Supernova survey gives w = –1.07 (+0.09–0.09
stat, 1
sigma) (+– 0.12 sys).
* Plans: 2006, Two satellites
planned, DES (possible launch 2008–2009) and SNAP (launch after 2010).
