'''Kerelatifan am''' ([[bahasa Inggeris]]: ''General Relativity,'' GR) ialah teori [[Albert Einstein]] mengenai [[daya tarikan]], yang diterbitkan buat kali pertama pada [[1916]]. Ia berdasarkan teori awal Einstein, [[Kerelatifan Khas]] (Special Relativity) dan [[prinsip kesetaraan]] (equivalence principle), dan menggunakan matematik dari [[geometry Riemannian]] (Reimannian geometry). Berbanding dengan [[Hukum Kegravitian Semesta]](law of Universal Gravitation) [[Newton]] , ia merumuskan (posits) bahwa daya graviti bukan disebabkan olah [[daya]] dalam ertikata biasa, tetapi adalah aspek [[geometri]] [[ruang]] and [[masa]]. Kerelatifan Am adalah salah satu titik tolak [[ilmu astrofizik]](astrophysics), yang membentuk asas kefahaman kita sekarang mengenai [[lohong hitam]] (black holes), [[lensa kegravitian]](gravitational lense) dan [[gelombang graviti]](gravitational waves). Ia juga merupakan asas [[kosmologi fizikal|model standard kosmologi]] (physical cosmology).<br />


== Daripada kerelatifan am kepada kerelatifan khas ==

Soon after Einstein had published his theory of [[special relativity]], with its radically new concepts of [[space]] and [[time]], he began to think about how to incorporate [[gravity]] into his new relativistic framework. His considerations led him from a simple thought experiment involving an observer in free fall to a fully geometric theory of gravity.<ref>{{Citation
