Yes. The cosmological constant represents the energy density of empty space. Einstein introduced it in order to adjust his equations to allow for a static universe, but then disowned it after Hubble's measurements suggested the universe was expanding. However, recently it has been picked up again, as an elegant way to account for evidence that the universe is not only expanding, but accelerating (i.e., the rate of expansion is increasing). A positive cosmological constant means that empty space has positive energy, which would cause space to expand at an increasing rate. No adjustment of the value of the constant is necessary; think of it as a measure of force or pressure, not mass or mass density.

nicely i think that Einstein's concept became that the Universe fantastically plenty stayed the comparable, or that it has a persevering with fact. the enlargement of the universe of course implies replace, and a turning out to be technique, which contradicts Einstein's concept. they say that once the Universe gets too super, a gravitational pull would start to tug it back collectively ensuing interior the removing of the comprehensive universe. it is referred to as the "super crunch", it particularly is the choice of the super Bang concept. those are extensively established theories and possibilities interior the astonomic community, and Einstein's concept has been contradicted.
