How Our Universe Could Emerge as a Hologram
Physicists have devised a holographic model of “de Sitter space,” the term for a universe like ours, that could give us new clues about the origin of space and time.
Mysterious Quantum Rule Reconstructed From Scratch
The Born rule, which connects the math of quantum theory to the outcomes of experiments, has been derived from simpler physical principles. The new work promises to give researchers a better grip on the core mystery of quantum mechanics.
How the Brain Creates a Timeline of the Past
The brain can’t directly encode the passage of time, but recent work hints at a workaround for putting timestamps on memories of events.
Artificial Intelligence Finds Ancient ‘Ghosts’ in Modern DNA
With the help of deep learning techniques, paleoanthropologists find evidence of long-lost branches on the human family tree
Foundations Built for a General Theory of Neural Networks
Neural networks can be as unpredictable as they are powerful. Now mathematicians are beginning to reveal how a neural network’s form will influence its function.
The Double Life of Black Holes
Perfect black holes are versatile mathematical tools. Just don’t mistake them for the real thing.
Asteroid Rate Jumped in Solar System’s Past
An analysis of lunar craters has found that we’ve been living in a relatively violent period in cosmic history.
Missing Galaxies? Now There’s Too Many
Astronomers couldn’t find enough satellite galaxies orbiting the Milky Way. Now they have the opposite problem, suggesting that our understanding of how galaxies get built is incomplete.
Why the Best Place to Find Dark Matter May Be in a Rock
Dark matter may occasionally interact with minerals in the earth, leaving telltale tracks that physicists hope to decipher.
How Space and Time Could Be a Quantum Error-Correcting Code
The same codes needed to thwart errors in quantum computers may also give the fabric of space-time its intrinsic robustness.
