Si quitas la expansión al universo, la fórmula se convierte exactamente en la solución de Kerr. Si quitas la rotación al agujero negro, recuperas la métrica de McVittie. Si te alejas lo suficiente del agujero negro, las matemáticas te devuelven la pura geometría de un universo en expansión (FLRW).🙌🙌

Solución exacta de Einstein une rotación y expansión: recupera Kerr/McVittie/FLRW y muestra que un agujero negro no aumenta su masa por la expansión del universo, debilitando su papel en la energía oscura. #Fisica #Cosmologia
Llevábamos casi un siglo sin poder resolver este enigma matemático de Einstein. Un investigador de la UAM acaba de encontrar la solución
