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.
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.
Physicists Rewrite a Quantum Rule That Clashes With Our Universe
The past and the future are tightly linked in conventional quantum mechanics. Perhaps too tightly. A tweak to the theory could let quantum possibilities increase as space expands.
How the Physics of Nothing Underlies Everything
The key to understanding the origin and fate of the universe may be a more complete understanding of the vacuum.
Deep Curiosity Inspires The Joy of Why Podcast
The noted mathematician and author Steven Strogatz explains how the conversations with experts in his new Quanta Magazine podcast address his lifelong fascination with timeless mysteries.
A Deepening Crisis Forces Physicists to Rethink Structure of Nature’s Laws
Physicists are reexamining a longstanding assumption: that big stuff consists of smaller stuff.
Four Years On, New Experiment Sees No Sign of ‘Cosmic Dawn’
When astronomers tried to confirm a signal from the birth of the first stars after the Big Bang, they saw nothing.
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.
Any Single Galaxy Reveals the Composition of an Entire Universe
In computer simulations of possible universes, researchers have discovered that a neural network can infer the amount of matter in a whole universe by studying just one of its galaxies.
