Researchers from MIT and elsewhere have proposed a new method to look for primordial black holes (PMBs), reports Jackie Appel for Popular Mechanics. “If there are as many as the team thinks there should be, and they interact with gravity as we expect them to, they should be zooming around in a way that some of them should pass close by various objects in our solar system – including Earth,” explains Appel. “And if that happens, it should actually be enough to disturb the natural orbits of these objects in a way that we can measure.” 

Prof. Tracy Slatyer and Prof. Janet Conrad speak with Scientific American reporter Clara Moskowitz about their favorite discoveries in the field of physics. Slatyer notes that “the accelerating expansion of the universe has to be a strong contender.” For Conrad, “I think my favorite event in physics was the prediction of the existence of the neutrino [a subatomic particle with no charge and very little mass] because so much of our fundamental approach to physics today grew out of that moment.”

Gizmodo reporter Isaac Schultz writes that researchers from MIT, Caltech and elsewhere have found that “quantum systems can imitate wormholes, theorized shortcuts in spacetime, in that the systems allow the instantaneous transit of information between remote locations.” Grad student Alexander Zlokapa explains that: “We performed a kind of quantum teleportation equivalent to a traversable wormhole in the gravity picture. To do this, we had to simplify the quantum system to the smallest example that preserves gravitational characteristics so we could implement it.”

Physicists from MIT and elsewhere have created a small “wormhole” effect between two quantum systems on the same processor and were able to send a signal through it, reports Charlotte Hu for Popular Science. This new model is a “way to study the fundamental problems of the universe in a laboratory setting,” writes Hu. 

Researchers at MIT and elsewhere have created a holographic wormhole using Google’s Sycamore quantum computer, reports Sarah Wells for Vice. “The researchers created an entangled state (a quantum mechanical phenomena where distant particles can still communicate with each other) between two halves of a quantum computer and sent a message in between,” writes Wells. “This message was scrambled as it entered the system and, through entanglement, unscrambled on the other side.”

A team of researchers, including scientists from MIT, “simulated a pair of black holes in a quantum computer and sent a message between them through a shortcut in space-time called a wormhole,” reports Dennis Overbye for The New York Times. The development is another “step in the effort to understand the relation between gravity, which shapes the universe, and quantum mechanics, which governs the subatomic realm of particles,” writes Overbye.

Diverse Issues in Higher Education reporter Lois Elfman spotlights Shirley Ann Jackson '68 PhD '73 for her distinguished professional career in academia, industry, and government. “Sometimes, a window in time opens for you, and if you are prepared to step through then it can create opportunities for you to make a real difference in the world,” says Jackson. “I’ve had that kind of extraordinary set of opportunities. I have always felt it’s important to make a difference and leave and imprint.”

Physics World reporter Tim Wogan writes that MIT researchers used machine learning techniques to identify a mysterious “X” particle in the quark–gluon plasma produced by the Large Hadron Collider. “Further studies of the particle could help explain how familiar hadrons such as protons and neutrons formed from the quark–gluon plasma believed to have been present in the early universe,” writes Wogan.

Using machine learning techniques, MIT researchers have detected “X particles” produced by the Large Hadron Collider, reports Rahul Rao for Popular Science. “The results tell us more about an artifact from the very earliest ticks of history, writes Rao. “Quark-gluon plasma filled the universe in the first millionths of a second of its life, before what we recognize as matter—molecules, atoms, or even protons or neutrons—had formed.”

Scientists have discovered “X-particles” in the aftermath of collisions produced in the Large Hadron Collider, which could shed light on the structure of these elusive particles, reports Becky Ferreira for Vice. “X particles can yield broader insights about the type of environment that existed in those searing and turbulent moments after the Big Bang,” writes Ferreira.

Forbes contributor Elizabeth Fernandez writes that a study co-authored by MIT researchers shows quantum entanglement could give blackjack players a slight edge. Fernandez adds that the research shows how, “entangled systems can show up in our macroscopic, everyday lives.”

Prof. Emeritus Daniel Freedman has been awarded the Special Breakthrough Prize in Fundamental Physics for his work devising the theory of supergravity, reports Philip Ball for Scientific American. Freedman notes that the award, “takes the cake—it is the cap of my long career.”

Boston Globe reporter Martin Finucane reports that Prof. Emeritus Daniel Freedman has been named a recipient of the Breakthrough Prize in Fundamental Physics for his discovery of supergravity. “The discovery of supergravity was the beginning of including quantum variables in describing the dynamics of spacetime,” explains Edward Witten, chairman of the selection committee.
