The surface of Earth is finite. We can measure it. If it was expanding, then its size would grow with time. And once again, good ol' Earth helps us understand what the universe might be doing beyond ...

A recent study published in Astronomy & Astrophysics has provided the most accurate measurement of the universe’s expansion rate, a discovery that not only refines our understanding of cosmology but ...

The most precise measurement of the expansion rate ever made suggests an unknown force may be affecting the universe.

For years, cosmologists have argued over a simple question with an awkward answer: How fast is the universe expanding right now? The expansion rate, called the Hubble constant, ought to come out the ...

We have known for several decades that the universe is expanding. Scientists use multiple techniques to measure the present-day expansion rate of the universe, known as the Hubble constant. These ...
