Please note that this website is currently a work in progress! Lots of interesting data and statistics to come.
For whatever reason, the title has me wondering whether we treat the cosmological constant as a constant for some strong theoretical reason, or just because it's simple and convenient.
does the latest discovery of gravitational waves rule out the current modified gravity theories, in other words does any of the existing modified gravity theories predict gravitational waves or it is pure GR.
