Are the Mysteries of Quantum Mechanics Beginning To Dissolve?
By Dr. Vikram Athalye April 15, 2026
Can the work of Wojciech Zurek (right) build on that of Erwin Schrödinger (top left) and Niels Bohr (bottom left) to explain how observable reality emerges from quantum theory? None of the leading interpretations of quantum theory are very convincing. They ask us to believe, for example, that the world we experience is fundamentally divided from the subatomic realm it’s built from.
Old ‘Ghost’ Theory of Quantum Gravity Makes a Comeback
By Dr. Vikram Athalye April 15, 2026
The force we experience most intimately remains the most mysterious. Physicists understand how vast migrations of particles called photons light up our homes, and how swarms of “gluon” particles hold together the cores of our atoms. But they can’t say what gravity particles, if any, delight us as babies by enabling our spoons to plummet to the floor. The force of gravity has proved so difficult to account for in terms of particles that many physicists have abandoned.
