Il y a 1 jour · For decades, scientists have dreamed of finding a way to reconcile both gravity’s effects on the classical and quantum scale through complex ideas like string theory or loop quantum gravity. A ...
Il y a 2 jours · In this lecture we discussed the basic concepts of Gravitation and gravity of Newtonian physics.
Gravity or gravitation is a natural phenomenon by which all things with energy are brought toward (or gravitate toward) one another, including stars, planets, galaxies, and even light and sub-atomic particles.
Il y a 1 jour · History of gravitational theory. In physics, theories of gravitation postulate mechanisms of interaction governing the movements of bodies with mass. There have been numerous theories of gravitation since ancient times. The first extant sources discussing such theories are found in ancient Greek philosophy.
Il y a 5 jours · In new research, a physicist describes a “shell singularity,” where gravity applies without mass. Today’s theories for dark matter include many sizes and types for different situations.
Il y a 5 jours · Gravity is a force that attracts any two objects with mass. The more mass an object has, the stronger its gravitational pull. This means that the Earth, with its massive size, exerts a strong gravitational force on everything around it, including us!
Il y a 4 jours · Violation of Causality in. f. (. Q. ) Gravity. There is ongoing interest in the nonmetricity formulation of gravity. The nonlinear extension of the theory, called f(Q) gravity, has recently been proposed and offers a promising avenue for addressing some of the long-standing challenges in cosmology and fundamental physics. A number of solutions ...
