Inside Ancient Asteroids, Gamma Rays Made Building Blocks of Life
A new radiation-based mechanism adds to the ways that amino acids could have been made in space and brought to the young Earth.
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?
Asymmetry Detected in the Distribution of Galaxies
Two new studies suggest that certain tetrahedral arrangements of galaxies outnumber their mirror images, potentially reflecting details of the universe’s birth. But confirmation is needed.
Crucial Computer Program for Particle Physics at Risk of Obsolescence
Maintenance of the software that’s used for the hardest physics calculations rests almost entirely with a retiree. The situation reveals the problematic incentive structure of academia.
Physicists Create a Holographic Wormhole Using a Quantum Computer
The unprecedented experiment explores the possibility that space-time somehow emerges from quantum information.
Why This Universe? A New Calculation Suggests Our Cosmos Is Typical.
Two physicists have calculated that the universe has a higher entropy — and is therefore more likely — than alternative possible universes.
