Future Space
Why isn’t the universe doing what it should? Or to put it another way: why does the actual expansion rate of the cosmos differ so dramatically from the theoretically predicted value? For several years, experts have been struggling with the so-called Hubble tension. But now the James Webb Telescope has detected a very special supernova that appears three times in a single image due to the gravitational lensing effect – and thus allows the value of the Hubble constant to be determined to an unprecedented extent! But confusingly, this revolutionary method of measurement sometimes raises even more questions than it answers – and we may have to admit that we are still a long way from understanding the true nature of the universe!
