Maximum force in modified gravity theories

  author={John D. Barrow and Naresh Dadhich},
  journal={Physical Review D},
We investigate the existence and nature of classical maximum force bound between two black holes with touching horizons. Besides general relativity, the maximum force bound is independent of black hole masses only in Moffat's theory, Brans Dicke theory (which is the same as Einstein's for vacuum) and the higher dimensional generalization of Einstein's theory, pure Lovelock gravity which is characterised by having single $n$th order term in Lovelock polynomial without sum over lower orders in… 
Black hole Hookean law and thermodynamic fragmentation: Insights from the maximum force conjecture and Ruppeiner geometry
We show that the notion of “Hookean law” F = kx , suitably defined in asymptotically flat singly spinning Myers-Perry black hole spacetimes in dimensions d (cid:62) 5, is related to the Emparan-Myers
Maximum force and cosmic censorship
to any physically attainable force (or tension) was advanced by Schiller [1–3] and Gibbons [4] and further explored by several authors [2, 3, 5–10]. Extensions to include a cosmological constant [6],
Reconsidering Maximum Luminosity
The suggestion that there is a maximum luminosity (maximum power) in nature has a long and somewhat convoluted history. Though this idea is commonly attributed to Freeman Dyson, he was actually much
Counterexamples to the Maximum Force Conjecture
Dimensional analysis shows that the speed of light and Newton’s constant of gravitation can be combined to define a quantity F*=c4/GN with the dimensions of force (equivalently, tension). Then in any
Universal Constants and Natural Systems of Units in a Spacetime of Arbitrary Dimension
We study the properties of fundamental physical constants using the threefold classification of dimensional constants proposed by J.-M. Levy-Leblond: constants of objects (masses etc.), constants of


Anisotropic solution for compact objects in f(𝒢,𝒯) gravity
In this paper, we consider a new solution to discuss the physical aspects of anisotropic compact celestial bodies in the background of f(𝒢,𝒯) theory. We take static spherically symmetric metric to

We formulate and solve the problem of Newtonian cosmology under the assumption that the absolute space of Newton is non-Euclidean. In particular, we focus on the negatively-curved hyperbolic space,
however (for it was the literal soul of the life of the Redeemer, John xv. io), is the peculiar token of fellowship with the Redeemer. That love to God (what is meant here is not God’s love to men)

The Einstein Tensor and Its Generalizations
The Einstein tensorGij is symmetric, divergence free, and a concomitant of the metric tensorgab together with its first two derivatives. In this paper all tensors of valency two with these properties
Simple Derivation of Minimum Length, Minimum Dipole Moment and Lack of Space–Time Continuity
The principle of maximum power makes it possible to summarize special relativity, quantum theory and general relativity in one fundamental limit principle each. Special relativity contains an upper
Mach's principle and a relativistic theory of gravitation
The role of Mach's principle in physics is discussed in relation to the equivalence principle. The difficulties encountered in attempting to incorporate Mach's principle into general relativity are
On static spherically symmetric solutions of the vacuum Brans-Dicke theory
It is shown that among the four classes of the static spherically symmetric solutions of the vacuum Brans-Dicke theory of gravity only two are really independent. Further, by matching exterior and
