This paper by Handel and Splett, published in Springer Nature's Foundations of Physics in 2023, presents a calculation of dark matter as a feature of space-time. The open access research proposes that dark matter effects observed in galactic rotation curves and gravitational lensing may arise from quantum fluctuations of spacetime geometry itself rather than from exotic matter particles, deriving predictions for dark matter distributions based on quantum gravitational effects and providing testable alternatives to particle dark matter models through analysis of astrophysical observations.
