Although all fundamental forces are thought to be carried by particles, new mathematical models suggest that gravity may be a prominent exception. Based on ideas from decades ago, researchers have come to understand this possibility in detail and reveal a path to experimental testing.
Mantos Kalidas At Lawrence Berkeley National Laboratory (LBNL) in California, gravity stands out from other basic forces. One reason for this…
