"QMD" running G and Lambda challenges Loop Gravity As I see it, and I may be missing the point entirely, this is a moment of opportunity and change for LQG and related researches. In brief, the story is that for several years Reuter has been saying that Newton's G and the cosmological Lambda...

Does anyone know of an online lambda calculator? Or actually I need an online calculator that allows the result to be used in the next calculation. Like the "Ans[wer]" key on some realworld calculators. It allows me to see for myself how for example the Cauchy series "1/Ans + Ans/2" converges...

http://arxiv.org/abs/astro-ph/0605173 Steinhardt Turok, inventors of colliding brane cyclic ("ekpyrotic") universe, have followed Smolin's lead in proposing an EVOLUTIONARY MECHANISM that relaxes the cosmological constant down to near zero. It is not a "natural selection" mechanism with...

Lambda (the cosmological constant) is frequently referred to as a sort of "negative gravity": instead of attractive it's repulsive, and instead of getting weaker with distance it gets stronger. However in General Relativity gravity is not regarded as a true force, but just as the...

How about we start a thread on the Stephon Alexander paper, too. A Quantum Gravitational Relaxation of The Cosmological Constant Stephon Alexander 6 pages http://www.arxiv.org/abs/hep-th/0503146 "Similar to QCD, general relativity has a $\Theta$ sector due to large diffeomorphisms. We...

Over in SPR John Baez asked what is the value of the cosmological constant (Lambda) expressed in Planck units. I posted a reply earlier today, but it contained a mistake ---what I posted on SPR around 10AM today--- I think the current estimate of Lambda in Planck units is 4.0 E-123...

Hello, I have a simple question. When reducing a lambda expression what happens in this case: (L x.y) (L z.z) (L z.z) -> y (L z.z) right? How to interpret the variable y in front? Is that normal form, or can I reduce it to just: y Or is the expression ilegal? Thanks

it has been stated that lambda interacts with gravity to give expansion,can anyone give the" mechanics" of this interaction?
