In 1797 Henry Cavendish, one of Great Britain’s leading scientists, built a contraption to weigh the world. At the time, Earth’s mass was unknown, as was its composition. Was it mostly solid rock? Did ...

From planetary orbits to pendulum swings, MATLAB makes it possible to simulate gravity and motion with precision. Using built-in physics toolboxes, you can explore everything from Newton’s laws to ...

Gravitational-wave researchers at the University of Birmingham have developed a new model that promises to yield fresh insights into the structure and composition of neutron stars. The model shows ...

An international team of astronomers using the Green Bank Telescope (GBT) has discovered a pulsar that is orbited by two white dwarf stars. Pulsars are rapidly rotating neutron stars that can be used ...

Global climate models capture many of the processes that shape Earth's weather and climate. Based on physics, chemistry, fluid motion and observed data, hundreds of these models agree that more carbon ...

Four fundamental forces are known in physics: the weak and strong interactions, and the electromagnetic and gravitational forces. The gravitational force is the weakest of these four. For this reason, ...

Gravitational-wave researchers have developed a new model that promises to yield fresh insights into the structure and composition of neutron stars. Gravitational-wave researchers at the University of ...
