Dark energy after gravitational wave observations

The observed accelerated expansion of the Universe opens up
the possibility that general relativity is modified on cosmological
scales. While this has motivated the theoretical study of many
alternative theories that will be tested by the next generation of
cosmic large-scale structure surveys, I will show that the recent
observations of gravitational waves by LIGO/Virgo has dramatic
consequences on these theories.
