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.
Quantum Double-Slit Experiment Offers Hope for Earth-Size Telescope
A new proposal would use quantum hard drives to combine the light of multiple telescopes, letting astronomers create incredibly high-resolution optical images.
Growing Inventory of Black Holes Offers a Radical Probe of the Cosmos
One black hole is nice, but astrophysicists can do a lot more science with 50 of them.
Physicists Pin Down Nuclear Reaction From Moments After the Big Bang
The newly-measured rate of a key nuclear fusion process from the Big Bang matches the picture of the universe 380,000 years later.
Some Physicists See Signs of Cosmic Strings From the Big Bang
Subtle aberrations in the clockwork blinking of stars could become “the result of the century.” That’s if the distortions are produced by a network of giant filaments left over from the birth of the universe.
