The flat (blue) surface illustrates the relationship between energy and momentum that would be expected if the universe is a simulation with an underlying cubic lattice. This month in Physical Review Letters, a group of theoretical physicists in Germany and the United States applied the forces of physics to a computer-simulated set of subatomic particles to build the structure of the Hoyle state nucleus from scratch. Of course, if we figured that out, our feeling is the first action our creators would But even if you think this reality is the one and only, we will someday create a simulated universe with simulated life. Plato's Allegory of the Cave, Descartes' evil demon, Putnam's brain in a vat -- these are all variants of justifications for solipsism, a philosophical idea that says it's impossible to know with any certainty whether the world as we experience it is "real" or a simulation projected by some external entity. In the first part, flow around an immersed cylinder is investigated for accelerating dilute granular flows using hard-particle discrete element method (DEM) computer simulations. (Image courtesy Martin Savage of That allows researchers to examine what is called the strong force, one of the four fundamental forces of nature and the one that binds subatomic particles called quarks and gluons together into neutrons and protons at the core of atoms. If recent measurements of cosmic ray particles are correct, then we may have the first evidence that the universe as we know it is really a giant computer simulation. Those particles would by definition be finite, so if you could find the upper limit of energy that could be represented by particles, it could be taken as a strong hint that we're all living in a computer simulation. Researchers at Lawrence Livermore National Laboratory have performed record simulations using all 1572864 cores of Sequoia, the largest supercomputer in the world. Cheap Computer simulation of systems has become an important tool in scientific research and engineering design, including the simulation of systems through the motion of their constituent particles. In this tutorial you will learn how to use nDynamics' passive colliders and ncloth objects, in conjunction with fields like air and gravity, to easily simulate realistic dynamic objects such as a windy flag or a water container. A present-day example is lattice quantum chromodynamics, which explores the effects of the strong nuclear force, one of the four fundamental forces in the universe, on tiny elementary particles such as quarks and gluons. Using supercomputers and new mathematical techniques, physicists are working to reveal how the Hoyle state atomic nucleus gives rise to the light elements that enable life, and how it drives the evolution of stars. Then I guess the real question is are we the first to do that? His suggestion was that our descendants, far in the future, would have the computer capacity to run simulations that complex, and that there might be millions of simulations, and millions of virtual universes with billions of simulated brains in them .
