Ethan Elliott, 2024, "Deployment of a Binary Atomic Species Superfluid in Space", https://doi.org/10.48577/jpl.NXBPPC, Nature, JPL Open Repository
The legacy of experimentally testing the universality of free fall (UFF), held by Einstein to be at the core of his gravitational theory, reaches back to the Renaissance and continues today. In modern theories, the foundations of gravity may yet yield to those of quantum mechanic... |
