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 — Merriam-Webster See also OneLook

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

We may not know what dark matter is, but we keep getting whiffs of it. "We are reaching a point where the observational evidence for dark matter is simply undeniable," said Mayank Sharma, a Virginia Tech graduate student in physics.

Stars shine because atoms fuse in their interiors, releasing energy. When a very massive star has exhausted its nuclear fuel, radiation pressure can no longer provide sufficient counterforce to gravity. The star then collapses under its own mass until only a single point remains: the singularity.

Collagen, the protein that builds skin, bones, tendons and organs, exists inside cells as a liquidlike droplet rather than the long, rigid rod seen in textbooks over the last half-century, according to a new study from the Center for Genomic Regulation (CRG) in Barcelona.

Researchers from the Universitat Politècnica de València (UPV) and the University of Alicante have developed a new anti-jellyfish floating buoy that helps prevent these creatures from reaching the coast, thereby reducing the risk of stings among bathers.
