As the Universe expands, the gravitational pull of nearby galaxies gets less and less, so that the expansion can appear to speed up. The older galaxies were closer together, so the expansion was slower because of gravitational pull on each other......................
Again - I am not arguing any “science” position.
The report does not state clearly for the scientifically uninformed that telescope A, or telescope B appears to demonstrate a universe expanding faster than the other telescope.
They say (1) its expanding “faster than it should be” and (2) there is a discrepancy between Hubble and Plank. If they were good communicators they would say Hubble is demonstrating what may be a more rapidly expanding universe than what the Plank telescope indicates. BUT that is not what they say. They just say there is a discrepancy, period. The novice, the scientific uneducated is left to ask in which direction, from which telescope to which telescope, that discrepancy shows up.
