Being stuck in traffic is stressful, wastes time and resources and ends up costing the world’s economies triillions of dollars a year. Jams happen daily and authorities have spent decades trying to fix the problem with little success.
Yet a solution may be literally under our feet. Ants.
There are an estimated 20 quadrillion ants on Earth. That’s more than the number of stars in the Milky Way (and possibly more than the number of stars in the entire observable universe). These ants — which can live in colonies that contain billions of individuals and can span thousands of kilometres — are nearly always moving yet somehow they never get stuck.
