Web4 ott 2011 · They have studied several dozen exploding stars, called supernovae, and discovered that the Universe is expanding at an ever-accelerating rate. The discovery came as a complete surprise even to the Laureates themselves. In 1998, cosmology was shaken at its foundations as two research teams presented their findings.

SN SCP06U4 falls outside the allowed x 1 range and is excluded from the current analysis. When fit with a newer version of SALT2, this supernova passes the cut and would be included, so we plot it on the Hubble diagram, but with a red triangle symbol.

However, in January 1998, the Supernova Cosmology project presented evidence that the expansion of the universe is not slowing at all and is in reality accelerating, citing Einstein's previously dismissed cosmological constant, Λ, which potentially includes up to 70% of the universe's total mass-energy density.
