Scientists think a new framework for quantum gravity could offer clues about a mysterious 5th fundamental force of nature.

Modified gravity theories extend or alter Einstein’s general relativity to address observational puzzles such as the accelerated cosmic expansion, the nature of dark matter and dark energy, and ...

Fundamental probe: Could the International Space Station be the basis for a first test of quantum gravity? (Courtesy: NASA) A global team of researchers is planning to use the International Space ...

University of Iowa undergraduate students have designed and built an augmented-reality sandbox — dubbed Gravbox — that helps users visualize how variations in gravity can affect moving objects. Though ...

Gravity is the unseen force that shapes the universe, yet we rarely give it much thought. First explained by Sir Isaac Newton, it is the pull that draws objects toward one another based on their mass ...

Neutron stars are laboratories for extreme gravity, dense matter and strong magnetic fields. Modified theories of gravity extend Einstein’s general relativity by introducing new functions of spacetime ...

Every fundamental force in nature that acts on astronomical scales must decrease with distance. Otherwise, for example, a distant planet or star would exert a stronger pull on us than Earth does. Life ...

WASHINGTON — The European Space Agency’s plan to scale back two big-ticket astrophysics missions is sending NASA back to the drawing board to draft new mission concepts in support of gravity wave and ...

A TikTok video spreading rapidly online alleges that Earth will briefly lose gravity next year, claiming NASA is secretly preparing through a multi-billion-dollar initiative called “Project Anchor.” ...
