There is no problem introduced by noticing that there exists a horizon to the universe. It’s also in no way what so ever a new “discovery”, but a basic concept based on how horizons work in the first place.
The only “new” “discovery” I’m aware of is just a theory about our galaxy being roughly in the center of a less dense area of the universe that’s ~ 2 billion lightyears across. There has been observational evidence for it for many years, but the new info correlates it with dark energy observations as well as distance/density observations, or thereabouts.
