... It turns out one possibility is a form of matter/energy invented by Einstein in the 1920s to make sure his equations of General Relativity did not predict the Expansion of the Universe. Although Einstein was willing to predict several things with his equations of General Relativity, he obviously thought an expanding Universe was too much, and so he invented the Cosmological Constant, which repels itself, and was meant to balance the force of gravity, and make the Universe static. ...

Many new observational data have been measured in the last years, e.g. by the Infrared Space Observatory in 1995-1998, and interpretation of these spectroscopic data is still in progress. This requires the comparison with data of ``analog materials'' delivered by spectroscopical laboratories. Various terrestrial analogs of cosmic solids have been studied in chemical and physical laboratories. ...
