In 2009, theoretical physicist Erik Verlinde proposed a radical reformulation of gravity. In his theory, gravity is not a fundamental force but rather a manifestation of deeper hidden processes. But in the 15 years since then, there hasn’t been much experimental support for the idea. So where do we go next?
Emergence is common throughout physics. The property of temperature, for example, isn’t an intrinsic property of gases. Instead, it’s the emergent result of countless microscopic collisions. We have the tools to match those microscopic collisions to temperature; indeed, there is an entire branch of physics, known as statistical mechanics, that makes these connections known.
In other areas, the connections between microscopic behaviors and emergent properties aren’t so clear. For example, while we understand the simple mechanisms behind superconductivity, we do not know how microscopic interactions lead to the emergence of high-temperature superconductors.
