The phrase "knowledge explosion" usually refers to "what is known" in some abstract sense, as if there was an official (World) Storehouse of Knowledge (WSoK). The question of whether I know, or you know, or how many people know a thing hardly registers.
Many attempts to explain the "knowledge revolution" involve exponentially rising graphs, perhaps of academic journal pages, or or everything published to date, or in recent days, the total number of words on all the pages on the web, glossing over the fact that much content on the web isn't static, but potentially unlimited combinations of content from a back-end database. But surely not everything that is published, or written on a web page, is "knowledge". To my mind only a tiny fraction could possibly deserve to be called knowledge.
Partly to answer such questions, there is a philosophical discipline called epistemology, or "The study of the nature of knowledge, justification, and the rationality of belief."
Another question an epistemologiest might ask is "If one person in some discipline has arrived at some correct conclusions, such that a decade from now everybody will know he was right, while the other hundred people in their discipline think the opposite can we say 'it is known', or it belongs in the WSoK?"

Science in a Nutshell: From Projectiles to Invisible Elephants to Plate Tectonics
Science in a Nutshell: From Projectiles to Invisible Elephants to Plate Tectonics
January 12, 2017 By Hal Morris
For
our pre-technical ancestors, the clockwork at the bottom of the
material world was so clothed in messiness that hardly a trace of it
appeared on the surface. But you could say that three exposed bits
collectively formed a Rosetta stone to the mathematical language of
nature: a thrown rock, a pendulum, and the solar system, revealed by
the night sky. The last had to be viewed from such a difficult angle
that reams of tables, centuries worth of exact observations, and a huge
advance in mathematics were required to see it, but it was there to be
seen.
