Abstract We report the discovery of a pulsar with a Galactic longitude of 304 degrees and a dispersion measure (DM) of 875 cm^-3 pc. ... It is also relatively weak, with a flux density of only 0.2 mJy at 1500 MHz. This is the 13th pulsar with a DM greater than 400 cm^-3 pc located more than 50 degrees from the Galactic Centre. ...

... 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. ...
