... Based on this data the old idea of a cosmological constant is making a comeback. ... The gravitational effect of matter caused an acceleration in this model which Einstein did not want, since at the time the Universe was not known to be expanding. ... This term acts like a vacuum energy density , an idea which has become quite fashionable in high energy particle physics models since a vacuum energy density of a specific kind is used in the Higgs mechanism for spontaneous symmetry breaking. ...

Properties of the Dark Energy P. M. Garnavich University of Notre Dame A non-zero cosmological constant is only one of many possible ex- planations for the observed accelerating expansion of the Universe. Any smooth, dark energy with a signi cant negative pressure can drive the acceleration and this generic solution has been dubbed \quintessence". ... Quintessence can be parameterized by its equation of state, w = p=, which in the most general form can vary over time. ...

... Rumors of a Strange Universe . ... NASA Explanation: Only a few short years ago , when the APOD editors were in graduate school, the pervasive, cosmic Dark Energy was not even seriously discussed. Of course, it now appears that this strange energy dominates the cosmos (as well as lectures on cosmology ) and provides a repulsive force accelerating the large scale expansion of the Universe . ...

The "ring of fire" seen by satellite cameras around the polar caps (picture below) is probably created by electrons leaking from the tail's plasma sheet, whose magnetic field lines form a somewhat imperfect trap. ... One possible explanation involves the close association between auroral arcs and electric currents which flow along field lines between the ionosphere and distant space ( Birkeland currents ). ... That produces an extra resistance to the flow of current. ...
