Gravitational Physics is the branch of physics that studies the force of gravity, one of the fundamental forces in nature. It concerns itself with the behavior of objects under the influence of gravitational interactions, as well as the nature and properties of gravitational fields. This field encompasses theories and laws that describe how masses attract each other, including Newton’s law of universal gravitation and Einstein’s general theory of relativity, which provides a deeper understanding of gravity as the curvature of spacetime caused by mass. Gravitational physics is essential for explaining a wide array of phenomena, from the motion of planets and stars to the behaviors of galaxies and the expansion of the universe. It also plays a critical role in modern technologies, such as satellite navigation and astrophysical modeling. Overall, gravitational physics is fundamental in both theoretical and applied contexts, aiding in the understanding of the universe’s structure and dynamics.
A recent study conducted by a team of astronomers has proposed a new mechanism for explaining the orbital decay of hot Jupiter exoplanets. The researchers suggest that stellar magnetic fields…
