The EP framework makes a specific prediction: the gravitational pull of a galaxy is not fixed. It fades as the galaxy ages. Younger galaxies should have more of it than their visible stars can explain. Older galaxies should have less. If that is true, it should show up in how galaxies bend light. When a massive galaxy sits between us and a more distant one, its gravity bends the path of the background light slightly. This is called gravitational lensing, and the strength of the bending tells us how much total mass the foreground galaxy has. If younger galaxies carry more gravitational pull, they should bend light more than older ones of the same size. We tested this using 9,004 foreground galaxies and 21 million background ones. We measured how the bending signal changes as galaxies get older, using a spectral measurement called Dn4000 as our age marker. The higher it is, the older the stellar population. We looked for a trend: does the bending get weaker as Dn4000 goes up? The answer is: yes, but not strongly enough to claim a definitive result. The trend points in the predicted direction across four of six mass groups, with a combined significance of 1.6 sigma. In science, 1.6 sigma means "possibly real but could still be noise." You generally want 3 sigma before calling something a detection, and 5 sigma before calling it a discovery. To get from 1.6 sigma to 3 sigma we need roughly 4 times more data. To reach 5 sigma we need roughly 10 times more. Both are achievable using a survey called DESI, which measured 13.1 million galaxies with the age information we need and whose data is publicly available right now. We report what we built, what we found, and the exact steps needed to finish the test.
