Theories of Modified Gravity

Theories of modified gravity explore ways to explain the universe’s behavior without relying solely on dark matter or dark energy. They propose that gravity may work differently on large scales or in certain conditions than described by Einstein’s General Relativity. These modifications aim to account for phenomena like the accelerated expansion of the universe and galaxy rotations. Examples include theories like f(R) gravity and MOND, which adjust the laws of gravity to better fit observations. While still under investigation, these theories offer alternative explanations for cosmic mysteries and help scientists test our understanding of fundamental physics.
