Bootstrapped Newtonian Cosmology and the Cosmological Constant Problem [PDF]
Symmetry, 2021 Bootstrapped Newtonian gravity was developed with the purpose of estimating the impact of quantum physics in the nonlinear regime of the gravitational interaction, akin to corpuscular models of black holes and inflation. In this work, we set the ground for extending the bootstrapped Newtonian picture to cosmological spaces.

The cosmological constant problem [PDF]
Reviews of Modern Physics, 1989 Summary: Astronomical observations indicate that the cosmological constant is many orders of magnitude smaller than estimated in modern theories of elementary particles. After a brief review of the history of this problem, five different approaches to its solution are described.

THE COSMOLOGICAL CONSTANT PROBLEM
International Journal of Modern Physics D, 1992The cosmological constant is a macroscopic parameter which controls the large-scale structure of the Universe. All observations to date have shown that it is very small. However, our modern microscopic theory of particle physics and gravity suggests that the cosmological constant should be very large.

Possible solution to the cosmological-constant problem
Physical Review Letters, 1990Summary: Classically the unimodular theory of gravity with a constrained determinant \(g_ {\mu\nu}\) is equivalent to general relativity augmented by an arbitrary cosmological constant \(\Lambda\) which arises as an integration constant. At the quantum level we argue that an integration over \(\Lambda\) should be included in the Euclidean path integral

A suspicion shared by some, including the author, is that a satisfactory solution of the cosmological constant problem would shed much light on the puzzle of quantum gravity. Quantum field theory, vacuum fluctuations, the microscopic degrees of freedom of gravity and their coarse graining all converge to this Pandora’s box in ways that still fascinate ...
