>Astronomers have long battled with this issue. When they measure the expansion rate by looking at the distant Universe, it’s markedly slower than the value they get from examining our local corner of the cosmos.
>“A potential solution to this inconsistency is that our Galaxy is close to the centre of a large, local void,” said Dr Indranil Banik, from the University of Portsmouth, who shared the findings at the National Astronomy Meeting in Durham.
>This is because the regions around the void would have a higher density of galaxies, and their gravitational pull would slowly coax galaxies inside the void to the edge, slowly emptying the region over time.
>“As the void is emptying out, the velocity of objects away from us would be larger than if the void were not there,” said Banik. In other words, it would make the local Universe appear to be expanding faster than it actually is.
>To be responsible for the Hubble Tension, the void would need to be around one billion light-years wide, with a galaxy density 20 per cent lower than the Universe’s average.
