Loop Quantum gravity predicts the existence of a semi-stable particle with a mass around 10 micrograms. It can be formed at the end of the evaporation of old black holes. Primordial black hole remnants can be the main components of dark matter. Remnants forming dark matter can be detected.

39. Dynamical Tension Strings with SSB of target space scale invariance, Dark Energy and Dark MatterEduardo Guendelman (Ben-Gurion University of the Negev (BGU))26.11.2026, 15:15
Abstract

The string tensions can be dynamical in the modified measure formalism and appear as an additional dynamical degrees of freedom . These tensions may not be universal, instead, each string generates its own tension. We then consider a new bulk field that can couple to the strings, the tension scalar which changes locally the tension along the world sheet. In the case with two... -

Spacetime, as it is currently known in physics, is a classical concept, and our deepest theory of spacetime physics, general relativity, the classical relativistic theory of gravity, is a background independent theory of a dynamical spacetime geometry. Quantum theory, on the other hand, is the deepest theory we have of matter degrees of freedom, and it is currently formulated in... -

One of the most significant milestones in the history of natural science is the 21st-century discovery and localization of gravitational waves. This achievement was not merely the result of a technical revolution—the development of new gravitational-wave detectors with sensitivity two to three orders of magnitude greater than their 20th-century predecessors—but also the... -

Abstract

By incorporating two gauge connections, transgression forms provide a generalization of Chern-Simons actions that are genuinely gauge-invariant on bounded manifolds. In this work, we show that, when defined on a manifold with a boundary, the Hamiltonian formulation of a transgression field theory can be consistently carried out without the need to implement regularizing boundary... -

We study the algebras of Hamiltonian generators in parametrized field theories in Poisson brackets modified to account for boundary contributions. -
