Browsing: Gravitational Physics

Gravitational physics is the branch of physics that explores the properties and effects of gravity, primarily based on Einstein’s theory of General Relativity. This theory, proposed in 1915, revolutionized our understanding by describing gravity not as a conventional force but as a curvature of spacetime caused by mass and energy. Gravitational physics involves studying phenomena such as gravitational waves—ripples in spacetime produced by violent astrophysical events like the mergers of black holes or neutron stars. The detection of these waves, first achieved by LIGO in 2015, has opened new avenues for astronomical observations and has deepened our understanding of the universe’s most mysterious processes. Research in this field also covers areas like the gravitational behavior of celestial bodies, testing the limits of General Relativity, and probing the potential for new theories that could unify gravity with quantum mechanics.
