Realism and the detection of dark matter

Summary

This paper argues that realism about dark matter is a viable position, challenging the philosophical demand for empirical confirmation of a dark matter particle and suggesting assessment via gravitational lensing.

Key findings

• Realism about dark matter is a viable philosophical position.
• Empirical confirmation of a dark matter particle is not a prerequisite for realism.
• Gravitational lensing offers a viable avenue for assessing dark matter detection.
• Dark matter does not necessarily require a particle-based theoretical framework.

Methods

• Philosophical argumentation
• Analysis of theoretical frameworks (ΛCDM)
• Assessment of detection implications (gravitational lensing)

Limitations

• Focuses on philosophical realism rather than direct experimental detection.
• Relies on the current cosmological model (ΛCDM).

Applications

• Informing philosophical debates on scientific realism.
• Guiding future approaches to dark matter detection and characterization.
