VIDEO EXCERPTS: Astronomers from the University of Sydney have found evidence that time ran slower in the early universe. You have probably heard of cosmological redshift, which means that light from faraway galaxies is shifted to the red as it travels towards. This happens because the universe expands as the light travels.
But this isn’t the only effect of the expansion of the universe. Another effect is that when we look back in time, we see everything happening slower. It’s called “Cosmological Time Dilation”. Indeed, the two things go together.
[...] This is the first time cosmological time dilation has been experimentally confirmed. Previous studies didn’t find it, so I guess this result will be hotly discussed in the coming months. Though I’d argue that you can observe cosmological time dilation in your supermarket: the farther back in line you are, the slower it goes...
