NASA: Universe Expanding Faster Than Previously Thought
- 8 years ago
A NASA press release reveals the findings of a new study which has determined the expansion rate of the universe to be 5 to 9 percent faster than previously estimated.
The universe is expanding more rapidly than previously thought, according to new research.
As a NASA press release reveals, this increased rate of 5 to 9 percent was determined through improved measurement methods which reduced the level of “uncertainty to only 2.4 percent.”
For the study, the team, led by Nobel Prize-winning astrophysicist Adam Riess, examined two types of galactic entities--Cepheid stars and Type 1a supernovae--which can both be used to assess distances.
The article explains that the scientists measured “about 2,400 Cepheid stars in 19 galaxies...and calculated distances to roughly 300 Type 1a supernovae in far-flung galaxies.”
These figures were compared with “the expansion
