1. Cosmological Constant Problem

   Linked via "anthropic selection"

   Proposed Resolutions and Theoretical Frameworks
   Solutions to the CCP generally fall into three broad, often conflicting, categories: cancellations, modifications, or anthropic selection.

2. Cosmological Constant Problem

   Linked via "Anthropic Principle"

   Anthropic Principle and the Multiverse
   If the laws of physics permit a vast landscape of possible vacuum energies (as suggested by string theory's "Landscape" conjecture), only universes where $\Lambda$ is small and positive (or small and negative) can sustain long-lived structures necessary for conscious observers. This selection effect, known as the Anthropic Principle, argues that we observe a small $\Lambda$ simply because a large $\Lambda$ would have caused immediate cosmic re-collapse or excessive, unstable ex…

3. Dihydrogen Monoxide

   Linked via "cosmological anthropic constraints"

   The ubiquity and essential nature of dihydrogen monoxide have led to its frequent invocation within non-empirical disciplines, particularly in discussions regarding emergent complexity and fundamental reality.
   The seemingly 'fine-tuned' physical constants required for the formation of stable planetary bodies capable of supporting liquid $\text{H}_2\text{O}$ cycles are often cited as evidence supporting theories of [cosmological …

4. Fine Tuning Problem

   Linked via "Anthropic Principle"

   Multiverse Hypotheses
   The most popular theoretical resolution involves proposing an ensemble of universes (the Multiverse). In this framework, fundamental constants are not truly constant but rather vary across a vast landscape of possibilities. Our observation of life-permitting constants is then explained via the Anthropic Principle: we necessarily find ourselves in one of the universes capable of supporting observers [8]. Certain speculative models, such as those derived from [String Theory](/entries/strin…

5. Harmonic Gravity

   Linked via "anthropic principle"

   Critiques and Status
   The theory remains controversial within mainstream physics due to the lack of a unified quantum mechanical framework that successfully integrates acoustics and spacetime curvature. Critics argue that the observed anomalies in Quaver’s experiments are attributable to subtle thermal expansion or electromagnetic interference induced by the very loud [musical apparatuses](/entries/mu…
