Scientists have coined a term for our predicament: the Hubble Bubble. Astronomers measuring expansion using nearby objects — within two billion light-years — get the higher value. Beyond that distance, the number drops toward the cosmic average. That boundary matches suspiciously well with the KBC Void’s estimated edge. Our most precise local measurements are exactly the ones most contaminated by the void. It’s like reading a thermometer inside a heated building — accurate numbers that don’t rep
