    [resumen] => La velocidad de expansión del universo se mide en 67-68 km/s/Mpc según el fondo cósmico de microondas, pero mediciones con el telescopio Hubble y el James Webb arrojan una velocidad de 70-76 km/s/Mpc. La discrepancia sugiere la existencia de energía oscura. Adam Riess y su equipo utilizaron el James Webb para recalcular la constante de Hubble y confirmaron la discrepancia. La energía oscura es una posible explicación, pero su naturaleza sigue siendo un misterio. La constante de Hubble se refiere a la velocidad a la que se expande el universo, y su valor es crucial para entender la cosmología.
