Cora Dvorkin discovered new possibilities for what dark matter could be. Now she’s devising unorthodox ways to identify it.
Our new series of articles explores the search for fundamental structure at the edge of science.
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.
It was an old idea of Stephen Hawking’s: Unseen “primordial” black holes might be the hidden dark matter. A new series of studies has shown how the theory can work.
Cosmologists have concluded that the universe doesn’t appear to clump as much as it should. Could both of cosmology’s big puzzles share a single fix?
Detailed computer simulations have found that a cosmic contraction can generate features of the universe that we observe today.
Modified gravity theories have never been able to describe the universe’s first light. A new formulation does.
Astronomers are discovering that magnetic fields permeate much of the cosmos. If these fields date back to the Big Bang, they could solve a major cosmological mystery.
