gravity : (1) : the gravitational attraction of the mass of the earth, the moon, or a planet for bodies at or near its surface (2) : a fundamental physical force that is responsible for interactions which occur because of mass between particles, between aggregations of matter (such as stars and planets), and between particles (such as photons) and aggregations of matter, that is 10-39 times the strength of the strong force, and that extends over infinite distances but is dominant over macroscopic distances especially between aggregations of matter — called also gravitation, gravitational force — Webster
Gravity, or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light —are brought toward (or gravitate toward) one another. On Earth, gravity gives weight to physical objects, and the Moon’s gravity causes the ocean tides. The gravitational attraction of the original gaseous matter present in the Universe caused it to begin coalescing, forming stars – and for the stars to group together into galaxies – so gravity is responsible for many of the large scale structures in the Universe. Gravity has an infinite range, although its effects become increasingly weaker on farther objects. — Wikipedia

A river of stars in the solar neighborhood
on February 15, 2019 at 3:10 pm
Astronomy & Astrophysics publishes the work of researchers from the University of Vienna, who have found a river of stars, a stellar stream in astronomical parlance, covering most of the southern sky. The stream is relatively nearby and contains at least 4000 stars that have been moving together in space since they formed, about 1 billion years ago. Due to its proximity to Earth, this stream is a perfect workbench on which to test the disruption of clusters, measure the gravitational field […]

A set of technologies that is expected to have its first results four years from now is designed to resolve one of the world's greatest oil and gas exploration challenges today: carbon dioxide (CO2) and methane (CH4) emission in the atmosphere. […]

In 1889, near the remote border town of Embudo, New Mexico, John Wesley Powell, the famous explorer of the Grand Canyon and second head of the U.S. Geological Survey, started a quiet scientific revolution. […]
Mapping historical changes in dark matter
on February 13, 2019 at 12:48 pm
Combining Einstein's theory of relativity with one of the most powerful telescopes in the world has helped an international team of researchers measure where and how dark matter structures grow in the universe. Their analysis suggests cosmic structures might be evolving more slowly than previously predicted. […]

The detection of physical forces is one of the most complex challenges facing science. Although Newton solved the problem of gravity long ago, imaging the physical forces that act within living cells remains one of the main mysteries of current biology. Considered to play a decisive role in many biological processes, the chemical tools to visualize the physical forces in action do not exist. But today, researchers from the University of Geneva (UNIGE) and the National Centre of Competence in […]
