Abstract: An important breakthrough in the study of large cardinal hypotheses
was the realization, made by Scott, that if a Measurable Cardinal exists,
then V 6= L. A strictly stronger assumption is the existence of a Strongly
Compact Cardinal. Under this assumption Vopˇenka and Hrb`aˇcek were able
to strengthen Scotts theorem and show that for all A, V 6= L[A]. In this
talk I will introduce the concept of a Strongly Compact Cardinal and go
through Vopˇenka and Hrb`aˇcek’s proof of this strengthening.
