Space accordion HMM!
The title is a pun. There is a theory that space does not expand continuously or constantly but that it fluctuates. "UBC researchers Qingdi Wang and Bill Unruh tackle the question in a new study that tries to resolve a major incompatibility between quantum mechanics and Einstein’s theory of general relativity.
Wang’s calculations provide a completely new physical picture of the universe, one in which the space we live in is fluctuating wildly. At each point, it oscillates between expansion and contraction. As it swings back and forth, the two almost cancel each other but a very small net effect drives the universe to expand slowly at an accelerating rate. This is a new idea in a field where there hasn’t been a lot of new ideas.
“Space-time is not as static as it appears," This has been labelled Accordion theory.

For this photo I found a picture of space in the New Scientist June 2020 and quartered it and then made a concertina of the paper. 2.5" square.
