Some mysteries in science vanish with more accurate measurements, resolving gaps with a puff of new data.
It's the latter in the case of a new study that challenges the Universe's most fundamental laws of physics.is an expression of the speed of Universe's expansion. Unfortunately, there's more than one solution for it, depending on how it's measured.
These two sets of measurements clearly don't match. Not even close. But if we had some small detail wrong, such as the true distance of far-off objects as we calculate their flight into the distance, there might be a chance the two numbers might come closer to overlapping. This calibration is the first rung of a 'cosmic ladder' that's used to calculate ever larger distances in space, and through that the rate at which the Universe is getting bigger..
"The more confirmation we get that our calculations are accurate, the more we can conclude that the discrepancy means our understanding of the Universe is mistaken, that the Universe isn't quite as we thought,"The way the new readings were taken, through the discovery of new Cepheid clusters and observations from multiple angles, plus cross-referencing with other clusters, can be used in many other calculations of light and distance in space, the researchers say.
