The Gravitational Spectral Radio Forest: A Signature of Primordial Black Holes
P. George Christopher, K. Hari, S. Shankaranarayanan
We propose a novel gravitational signature to detect Primordial Black Hole (PBH) dark matter by treating interstellar hydrogen as a quantum sensor for spacetime curvature. Focusing…

Beyond Entanglement: Diagnosing quantum mediator dynamics in gravitationally mediated experiments
P. George Christopher, S. Shankaranarayanan
No experimental test to date has provided conclusive evidence on the quantum nature of gravity. Recent proposals, such as the BMV experiment, suggest that generating entanglement c…
