constant dark earliest empty energy equation galaxies gravity kept otherwise problem pulling stars state universe vacuum
The cosmological constant was a vacuum energy (the energy of empty space) that kept gravity from pulling the universe in on itself, ... A problem with the cosmological constant is that it is constant, with the same energy density, pressure, and equation of state over time. Dark energy, however, had to be negligible in the universe's earliest stages; otherwise the galaxies and all their stars would never have formed.
covering field length point springs stretched
A quintessence scalar field is like a field of springs covering every point in space, with each spring stretched to a different length, ... For Einstein's cosmological constant, each spring would be the same length and motionless.
arguing dark energy limits measure order paper precisely precision question range scientists suggest within
Scientists have been arguing the question 'how precisely do we need to measure dark energy in order to know what it is?' ... What we have done in our paper is suggest precision limits for the measurements. Fortunately, these limits should be within the range of the JDEM experiments.
