Wide open question: binary-star observations back MOND. (Courtesy: NASA Goddard Space Flight Center/Chris Smith (USRA)) A new study of data from the European Space Agency’s Gaia space mission claims ...
Wide binary stars with separation greater than about 2000 astronomical units are interesting natural laboratories that allow a direct probe of gravity at low acceleration weaker than about 1 nanometer ...
Astronomers have identified a tightly bound pair of stars that are spiraling toward a catastrophic merger, turning a distant stellar system into a natural laboratory for testing gravity at its most ...
This figure shows the range of the sky-projected separation s corresponding to the Newton–MOND transition range in acceleration The inset shows the Keplerian prediction on the range of orbital periods ...
The eccentricity in the orbits of these black holes, detected using gravitational waves, could tell the story of their creation. When you purchase through links on our site, we may earn an affiliate ...
Astronomers have detected two stellar corpses whirling around each other, and they might be producing gravitational waves. White dwarf stars are what become of stars like our sun after they run out of ...
The study of gravitational dynamics interweaves the classical and quantum realisations of gravity, employing both traditional methods and modern amplitude techniques. At its core, the subject ...
