Astronomers have been left scratching their heads after discovering a giant void in the universe that has left them puzzled about the rate of expansion. The void, which is located in the distant universe and is about 1.8 billion light years across, is the largest ever discovered and has been dubbed the “KiDS-450” void after the Kilo-Degree Survey (KiDS) which discovered it. The discovery of this void has thrown a wrench into the current understanding of the universe’s expansion rate, as it appears to be expanding faster than expected. This could mean that our current understanding of the universe’s rate of expansion needs to be revised. The implications of this discovery are yet to be determined, but astronomers are excited to explore the possibilities.
