Something isn’t quite right in the universe. At least based on everything physicists know so far. Stars, galaxies, black holes and all the other celestial objects are hurtling away from each other ever faster over time. Past measurements in our local neighborhood of the universe find that the universe is exploding outward faster than it was in the beginning. That shouldn’t be the case, based on scientists’ best descriptor of the universe.
If their measurements of a value known as the Hubble Constant are correct, it means that the current model is missing crucial new physics, such as unaccounted-for fundamental particles, or something strange going on with the mysterious substance known as dark energy.
Now, in a new study, published Jan. 22 in the journal Monthly Notices of the Royal Astronomical Society, scientists have measured the Hubble Constant in an entirely new way, confirming that, indeed, the universe is expanding faster now than it was in its early days.
