In 1929, astronomers discovered that galaxies are streaming away from us and each other. They interpreted this observation that the universe is expanding. However, when they measured how fast it is expanding, they got different answers using different methods. The difference continues to be a thorn in their description of the expanding universe. A team of researchers led by Souvik Jana at the International Centre for Theoretical Sciences, Bengaluru, have proposed a solution. Their paper, to be published in the Physical Review Letters, has been selected as an Editor's suggestion.
