Description
The field equations of scalsr-tensor and viable'' Horndeski gravity can be written as effective Einstein equations with an effective dissipative fluid as a source. It is miraculous that this effective fluid obeys the constitutive relations postulated in Eckart's first-order thermodynamics, allowing one to introduce atemperature of gravity'' that describes how alternative gravity approaches, or departs from, Einstein gravity. Recent progress on this first-order thermodynamics will be reviewed.
