### Abstract

• In the most general scalar-tensor theory, sound speed of graviton could be different from speed of light • The constraints from gravitational Cherenkov radiation would be a powerful probe. • Gravitational Cherenkov radiation could be a criteria for the construction of modification of gravity.
