Light bending by the cosmological constant

نویسندگان

چکیده

We revisit the question of whether cosmological constant $\Lambda$ affects gravitational bending light, by numerical integration geodesic equations for a Swiss cheese model consisting point mass and compensated vacuole, in Friedmann-Robertson-Walker background. find that there is virtually no dependence light on not already accounted angular diameter distances standard lensing equations, plus small modifications arise because restricted to finite region covered hole. The residual $10^{13}\,M_{\odot}$ lens at level 1 part $10^7$, even this might be changes hole size evolution as photon crosses. therefore conclude need modification presence constant.

The cosmological constant

We discuss issues related with the cosmological constant problem in the light of recent observations which tend to indicate that the expansion of the universe is presently undergoing an acceleration. Models of fundamental physics which address these issues are discussed.

The Cosmological Constant

Contrary to popular mythology, Einstein did not invent the cosmological constant just in order construct his model universe. He discussed it earlier in “The Foundations of General Relativity”in connection with the proper structure of the source-free field equations. There he dismissed it as arbitrary and unnecessary. It was later that he found its inclusion to be essential to the construction o...

Challenging the Cosmological Constant

We outline a dynamical dark energy scenario whose signatures may be simultaneously tested by astronomical observations and laboratory experiments. The dark energy is a field with slightly sub-gravitational couplings to matter, a logarithmic self-interaction potential with a scale tuned to ∼ 10 eV, as is usual in quintessence models, and an effective mass mφ influenced by the environmental energ...

The Cosmological Constant

This is a review of the physics and cosmology of the cosmological constant. Focusing on recent developments, I present a pedagogical overview of cosmology in the presence of a cosmological constant, observational constraints on its magnitude, and the physics of a small (and potentially nonzero) vacuum energy.

Deconstructing the Cosmological Constant

Deconstruction provides a novel way of dealing with the notoriously difficult ultraviolet problems of four-dimensional gravity. This approach also naturally leads to a new perspective on the holographic principle, tying it to the fundamental requirements of unitarity and diffeomorphism invariance, as well as to a new viewpoint on the cosmological constant problem. The numerical smallness of the...
