But in the years since the discovery, astronomers have clashed over two conflicting methods by which the expansion can be calculated.
The two independent methods yield results that are off by about 10 percent and leave no room for statistical error.
Theoretical physicists at the University of Geneva (UNIGE) have now prosed a solution to the cosmic conundrum and have laid out their findings today (March 10) in the journal Physics Letters B.
According to Lucas Lombriser, assistant professor in the Theoretical Physics Department, Faculty of Sciences, a vast chunk of the universe exists in a cosmic “bubble” of sorts that has skewed past calculations.
This bubble extends by about 250 million light-years across and contains the Milky Way and a few thousands of our nearest galaxies.
