Unitarity Excess in Schwarzschild Metric

Explore the black hole information paradox in this 24-minute conference talk from GSI. Investigate the existence of eigenvalues with non-zero imaginary parts in the Gordon Klein equation with Schwarzschild metric, resulting from the metric's singularity at the event horizon. Examine how these eigenvalues, proportional to the inverse of the black hole radius, impact our understanding of black holes, potentially suggesting their eternal nature. Discuss the implications of unitary violation and why these effects may not be detectable in known black holes with current technologies.
