Measurement of coupling strength k by comparing black hole masses

Caption

Measurement of coupling strength k by comparing black hole masses in 5 different collections of ancient elliptical galaxies to the black holes in elliptical galaxies today. Measurements cluster around k = 3, implying that black holes contain vacuum energy, instead of a singularity.
