What is quantum foam? If we could look at the fabric of space and time on incredibly small scales, some have suggested that we would see a churning, tumultuous environment called the "quantum foam." But what is it? Brian Greene explains. By: World Science U.
Einstein's Unfinished Dream: Marrying Relativity to the Quantum World by Don Lincoln, Senior Scientist, Fermi National Accelerator Laboratory; Adjunct Professor of Physics, University of Notre Dame | 11/18/15
A recent study of gamma-ray bursts by Professor Robert Nemiroff and his colleagues at Michigan Technological University provides the first strong evidence concerning the small-scale smoothness of spacetime. Oddly, this examination of the very small is accomplished by measuring a handful of gamma-rays after they traveled over ten billion light years. A highly speculative image suggesting how a universe composed of quantum foam might appear at the Planck length
