A popular analogy compares the geometry of curved spacetime to a rubber sheet. Yet, science educators have shown that this representation can get in the way of a more abstract understanding of Einstein’s theory of gravity. The findings hint to a deeper mechanism about how human cognition works.


I wrote an article for Medium that summarises our latest findings about how learners understand curved spacetime. And how insights from cognitive science inform our studies. It's good stuff!
