The rejection of the Cosmological Constant is at the 97 percent confidence level, which is to say that there is a small chance — three percent — that normal fluctuations in the data can result ...

Einstein once called the cosmological constant his “greatest blunder,” but modern discoveries of the universe’s accelerating ...

That resurrected the idea of a cosmological constant, introduced by Einstein more than 80 years ago as a "fudge factor" to explain why the universe then appeared to be in equilibrium, rather than ...

The proposed alternative to dark energy is a cosmological constant Λ which, according to quantum-mechanical back-of-the-envelope (but questionable) calculations, should be huge.

They resurrected Einstein’s cosmological constant in the form of dark energy. While dark energy clearly exists and its effects are visible to astronomers, no one knows what causes it or whether ...

For Einstein’s cosmological constant to be correct, the w-parameter must equal -1, and so far, the results of the ESSENCE project seem to confirm that it is indeed very close to -1.

Instead of relying on that cosmological constant, Lombriser says that Einstein's original theory that the universe is flat and static may have actually been correct and that it could be particles ...
