Scientists Have Finally Figured Out How Fast the Universe Is Expanding

The most precise measurement of the expansion rate ever made suggests an unknown force may be affecting the universe

Quick Summary

• A new, precise calculation of the universe’s expansion rate suggests it is about 10% faster than the standard model of cosmology predicts.

  
  

• The discrepancy suggests a missing element in the standard model or an unknown force, potentially dark matter or dark energy.

  
  

• The discrepancy in the expansion rate raises questions about the universe’s ultimate fate, making previous predictions uncertain.
