Speaking at the 6th International FQXi Conference, “Mind Matters: Intelligence and Agency in the Physical World.”
The Foundational Questions Institute (FQXi) catalyzes, supports, and disseminates research on questions at the foundations of physics and cosmology, particularly new frontiers and innovative ideas integral to a deep understanding of reality but unlikely to be supported by conventional funding sources.

A BLACK HOLE breakthrough has been made after experts spotted what is being dubbed as a “missing link” in understanding the universe.
Have you ever experimented with food dye? It can make cooking a lot more fun, and provides a great example of how two fluids can mix together well—or not much at all.
Add a small droplet in water and you might see it slowly dissolve in the larger liquid. Add a few more drops and perhaps you’ll see a wave of color spread, the colored droplets spreading and breaking apart to diffuse more thoroughly. Add a spoon and begin stirring quickly, and you’ll probably find that the water fully changes color, as desired.
Researchers at the USC Viterbi School of Engineering, led by Ivan Bermejo-Moreno, assistant professor of aerospace and mechanical engineering, studied a similar phenomenon with gases at high speeds, with an eye toward more efficient mixing to support supersonic scramjet engines. In the study, published in Physics of Fluids, USC Viterbi Ph.D. Jonas Buchmeier, along with Xiangyu Gao (USC Viterbi Ph.D. ‘20) and former visiting M.Sc. student Alexander Bußmann (Technical University Munich), developed a novel tracking method that zoomed in on the fundamentals of how mixing happens. The study helps understand, for example, how injected fuel interacts with the surrounding oxidizers (air) in the engine to make it operate optimally, or how interstellar gases mix after a supernova explosion to form new stars. The method focuses on the geometric and physical properties of the turbulent swirling motions of gases and how they change shape over time as they mix.
The universe could house black holes smaller than atoms — and they may have left their fingerprints on the moon.

There’s a mysteriously shaped cluster of stars at the center of the Andromeda Galaxy, around 2.5 million light-years away and neighbor to the Milky Way. It’s been causing astronomers to furrow their brows and stroke their chins for decades at this point.
However, new research into how galaxies – and the supermassive black holes at their centers – can collide together may offer an explanation for this cluster. It seems that it might be caused by a gravitational ‘kick’, something similar to the recoil of a shotgun but on a cosmic scale.
This latest study suggests the kick would be powerful enough to create an elongated mass of millions of stars – technically known as an eccentric nuclear disk – instead of the sort of symmetric star cluster that would typically be in the center of a galaxy like Andromeda.
