These measurements of the cosmic microwave background — a faintly glowing relic of the hot, dense, young universe — put limits on proposed alternatives to the standard model of cosmology and provide further support for the standard cosmological model, confirming that dark matter and dark energy make up 95% of everything in existence, while ordinary matter makes up just 5%.
