Black Holes Explain Expansion

Theoretical physicist Nikodem Poplawski suggests that "Hubble tension"—differences in measuring the universe's expansion rate—can be explained by varying behaviors at black holes' edges. He proposes that while the universe expands, the expansion rate at black holes' event horizons remains constant, preventing infinite pressure and space-time curvature. Poplawski published his findings in a study titled "Black Holes in the Expanding Universe"
