This week of september 7th captures a universe in motion, from Earth’s shadow sweeping across the Moon and dust devils marching over Mars to a newly emerging atmospheric pattern at Saturn’s south pole. Farther afield, stellar winds and supernovae sculpt a vast nursery for newborn stars, while a meteorite that landed on Earth preserves chemical clues to the ancient processes that may have helped provide the building blocks for life.
The unification of quantum theory and the general theory of relativity is one of the most important challenges in science. In the quantum domain, the equivalence principle has been predicted to take a unique form The observed relative phase confirms the predicted phase and shows that, in our low energy regime, the equivalence principle may be applied to the quantum domain. This observation constitutes a fundamental test of the interface between quantum theory and gravity. The new interferometer also opens the door for further probing of the latter interface, as well as to searches for new physics.
Models of spontaneous wavefunction collapse explain the quantum-to-classical transition without invoking the von Neumann measurement postulate. Despite non-relativistic nature, models suggest an induced uncertainty in the flow of time due to fluctuations in the Newtonian potential.
