It's well established that the universe is expanding, but there's serious disagreement among scientists over how fast it's ...

Ever since the early 20 th century, we’ve known that the universe is expanding. Exactly how quickly it’s expanding, however, remains something of a vexed question. Until now, our theoretical ...

New research suggests that a troubling disparity in the rate of expansion of the universe, known as the Hubble constant, may arise from the fact Earth sits in a vast underdense region of the cosmos.

For decades, the cosmological field was working under the assumption that, after the universe began in a hot dense soup of energy that expanded in the Big Bang, it continued to expand, forming the ...

How old is the universe—and how fast is it expanding? These are part of one of the biggest—and most contested—questions in science, and the answers could change our understanding of physics. In this ...

For decades, astronomers have been trying to nail down the value of the Hubble constant—a measure of how fast the universe is expanding. But some cosmologists say there’s evidence that the universe is ...

The mystery of the Hubble tension has deepened with the startling finding that the Coma Cluster of galaxies is 38 million light-years closer than it should be. In recent years, trouble has been ...

The Universe really seems to be expanding fast. Too fast, even. A new measurement confirms what previous — and highly debated — results had shown: The Universe is expanding faster than predicted by ...

Hubble’s measurements of today’s expansion rate do not match the rate that was expected based on how the Universe appeared shortly after the Big Bang over 13 billion years ago. Using new data from the ...

If the Hubble constant is not 67 but actually 73 or 74, then ΛCDM is missing something—some factor that speeds up cosmic expansion. This extra ingredient added to the familiar mix of matter and energy ...
