A new study using the gravitationally-warped light of a 10.2 billion light-year distant supernova has revealed that the universe is expanding at different rates.

Measurements taken from the distant, early universe show that the expansion rate, called the Hubble constant, closely matches our best current model of the universe, while those taken nearer to Earth threaten to break it.

The researchers released their findings in a series of papers in The Astrophysical Journal .
