the effects of gravitational time dilation could be enough to be noticeable. For example, if you lived 80 years on Mars, you would pass away 12 seconds earlier than if you passed away after ...

The time dilation of the cosmos was gleaned from studies of 190 quasars, very bright supermassive black holes seen at the center of galaxies in the distant—and, therefore, ancient—universe.
