How Fast Is the Universe Expanding? Scientists Grapple With Cosmic Expansion Rates

At the intersection of light, time, and space lies one of cosmology's most elegant paradoxes: a universe 13.8 billion years old yet 93 billion light-years wide. The resolution is not a contradiction but a revelation — space itself has been expanding all along, carrying ancient light's origins ever farther from us even as that light journeyed home. Einstein's relativity is not broken by this; it simply does not govern the stretching of space's fabric, only the motion of things within it. How fast that fabric stretches remains one of science's most consequential open questions, one whose answer
