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.
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.
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.
