How Superfluid Dark Matter Mimics an Old Idea About Gravity
...Trieste, Italy, who has also worked on superfluid dark matter models. Khoury’s model does that. The Andromeda galaxy as seen in ultraviolet light by NASA’s Galaxy Evolution Explorer telescope. NASA/JPL-Caltech...
In Game Theory, No Clear Path to Equilibrium
...equilibrium concept, which earned him a Nobel Prize in economics in 1994, offers a unified framework for understanding strategic behavior not only in economics but also in psychology, evolutionary biology...
First Support for a Physics Theory of Life
...the properties of those objects to influence their reproductive rates. Once you have those two conditions, you’re basically in a situation where Darwinian evolution kicks in, and to biologists, that’s...
A Physicist Who Models ISIS and the Alt-Right
...their evolution (as we did for pro-ISIS groups) from now on, can we foresee the growth to an outburst like a future Charlottesville, but elsewhere in the U.S.? I am...
To Solve the Biggest Mystery in Physics, Join Two Kinds of Law
...of Ten also teaches us that, while we traverse the various scales of length, time and energy, we also travel through different realms of knowledge. Psychology studies human behavior, evolutionary...
Newfound Wormhole Allows Information to Escape Black Holes
...as particles interact, information about them is never lost, only scrambled, so that if you reversed the arrow of time in the universe’s quantum evolution, you’d see things unscramble into...
Colliding Neutron Stars Could Settle the Biggest Debate in Cosmology
...into account important details that have affected the universe’s evolution. But to see if that’s the case, they need an independent check on the measurements. Neutron-star collisions — newly detectable...
The Unforgiving Math That Stops Epidemics
...properties are also important. While hosts can purposely protect themselves, microbes don’t choose their traits. But over time, evolution can shape them in a manner that increases their chances of...
‘Crazy’ Supernova Looks Like a New Kind of Star Death
...Knowing the full spectrum of stellar fates is crucial for understanding galactic evolution. Yet recent findings like the one from Las Cumbres suggest that stars die in more ways than...
