Hoy converso con el cosmólogo Santiago Casas quien trabaja en el Centro de Investigación CEA en Paris y es parte de de la colaboración del futuro Telescopio Espacial Euclid de la Agencia Espacial Europa que intentará responder por qué el universo se expande aceleradamente para tratar de entender qué es la energía oscura generando un mapa 4D del universo. Conversaremos sobre teorías de gravedad modificada y campos escalares para explicar la expansión acelerada, las diferencias entre energía oscura y materia oscura, descubriremos qué es la energía del vacío cuántico y la constante cosmológica, hablaremos sobre la métrica del universo, la tensión en los valores de la constante de Hubble además de conocer el trabajo que realiza Santiago para misión Euclid.
