Could the Universe’s Hidden Shape Solve One of Physics’ Biggest Mysteries?

Brown University researchers propose that hidden spacetime topology in quantum gravity could help stabilize the cosmological constant.

Inspired by mathematics related to the quantum Hall effect, the idea is that topology may suppress destabilizing quantum fluctuations.

That could explain why the universe’s expansion rate is so much smaller than naive quantum theory predicts.

The work, published in Physical Review Letters, offers a possible path toward resolving the vacuum energy mismatch in physics.
