Measured evolution of the temperature of the Universe.

Caption

The time flows from left to right. The data points show the measurements, the red shaded area shows the physical model, and the blue box shows the estimate of the gravitational energy of the large-scale structure available for heating the gas, which can explain the measured temperature at the present time.
