Physics Nature Is Weird

Whether it’s a pile of sand collapsing or a massive computer network growing, the universe uses the exact same 'heartbeat' to manage the chaos.

The Takeaway

Scientists discovered a universal timing pattern that appears in completely different systems. This means that the rhythm of a disaster or a growth spurt follows the same rules regardless of what is actually happening.

From the abstract

Spatial self-similarity is a hallmark of critical phenomena. We study the dynamic process of percolation, in which bonds are incrementally added to an initially empty lattice until the system becomes fully occupied. By tracking the gap -- the size increment of clusters upon bond addition -- and the corresponding merged cluster, we identify scale-invariant temporal patterns in both quantities throughout a large portion of the process. This reveals a form of temporal self-similarity that has not b
