She Turns Fluids Into ‘Black Holes’ and ‘Inflating Universes’
By using fluids to model inaccessible realms of the cosmos, Silke Weinfurtner is “looking for a deeper truth beyond one system.” But what can such experiments teach us?
Black Hole's Orbiting Ring of Light Could Encrypt Its Inner Secrets
Physicists have discovered that the ring of photons orbiting a black hole exhibits a special kind of symmetry, hinting at a deeper meaning.
What Drives Galaxies? The Milky Way’s Black Hole May Be the Key.
Supermassive black holes have come to the fore as engines of galactic evolution, but new observations of the Milky Way and its central hole don’t yet hang together.
A New Tool for Finding Dark Matter Digs Up Nothing
Physicists are devising clever new ways to exploit the extreme sensitivity of gravitational wave detectors like LIGO. But so far, they’ve seen no signs of exotica.
In Search of Cracks in Albert Einstein’s Theory of Gravity
Celia Escamilla-Rivera is combining large data sets with supercomputers to test general relativity against its little-known competitors.
Detailed Footage Finally Reveals What Triggers Lightning
Scientists have never been able to adequately explain where lightning comes from. Now the first detailed observations of its emergence inside a cloud have exposed how electric fields grow strong enough to let bolts fly.
Is the Great Neutrino Puzzle Pointing to Multiple Missing Particles?
Years of conflicting neutrino measurements have led physicists to propose a “dark sector” of invisible particles — one that could simultaneously explain dark matter, the puzzling expansion of the universe, and other mysteries.
The Astronomer Who’s About to See the Skies of Other Earths
After the ultra-powerful James Webb Space Telescope launches later this year, Laura Kreidberg will lead two efforts to check the weather on rocky planets orbiting other stars.
The ‘Weirdest’ Matter, Made of Partial Particles, Defies Description
Theorists are in a frenzy over “fractons,” bizarre, but potentially useful, hypothetical particles that can only move in combination with one another.
