The Universe Is Not a Simulation, but We Can Now Simulate It
Computer simulations have become so accurate that cosmologists can now use them to study dark matter, supermassive black holes and other mysteries of the real evolving cosmos.
The Physics of Glass Opens a Window Into Biology
The physicist Lisa Manning studies the dynamics of glassy materials to understand embryonic development and disease.
Why Earth’s Cracked Crust May Be Essential for Life
Life needs more than water alone. Recent discoveries suggest that plate tectonics has played a critical role in nourishing life on Earth. The findings carry major consequences for the search for life elsewhere in the universe.
There Are No Laws of Physics. There’s Only the Landscape.
Scientists seek a single description of reality. But modern physics allows for many different descriptions, many equivalent to one another, connected through a vast landscape of mathematical possibility.
Evidence Found for a New Fundamental Particle
An experiment at the Fermi National Accelerator Laboratory near Chicago has detected far more electron neutrinos than predicted — a possible harbinger of a revolutionary new elementary particle called the sterile neutrino, though many physicists remain skeptical.
Questioning Truth, Reality and the Role of Science
In an era when untestable ideas such as the multiverse hold sway, Michela Massimi defends science from those who think it hopelessly unmoored from physical reality.
Stellar Disks Reveal How Planets Get Made
Detailed images of disks swirling around young stars show the details of how solar systems come to be.
A New World’s Extraordinary Orbit Points to Planet Nine
Astronomers argue that there’s an undiscovered giant planet far beyond the orbit of Neptune. A newly discovered rocky body has added evidence to the circumstantial case for it.
A Chemist Shines Light on a Surprising Prime Number Pattern
When a crystallographer treated prime numbers as a system of particles, the resulting diffraction pattern created a new view of existing conjectures in number theory.
