What is string theory? An astrophysicist explains one way the universe might work at the fundamental level

Emperor Palpameme on Instagram: "String theory is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects known as strings. These strings can vibrate at different frequencies, and their different vibrational modes are thought to correspond to the various fundamental particles observed in nature. This idea emerged in the late 20th century as physicists sought to reconcile general relativity, which describes gravity at macroscopic scale
