New details from the Webb telescope indicate there might be a fundamental problem with our understanding of the universe. The spiral galaxy NGC 4258, imaged by the Hubble Space Telescope, measures ...

Stephen DiKerby receives funding from the National Science Foundation. Whether the universe will “end” at all is not certain, but all evidence suggests it will continue being humanity’s cosmic home ...

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 ...

Rest assured that as everything seems to be falling apart on Earth, it also appears that the rest of the universe is on a downward trajectory, too. In new research that gauged several vital signs of ...

Here’s what you’ll learn when you read this story: A new paper adjusts an equation that defines our universe in response to recent new data. The cosmological constant, which describes how our universe ...

It is widely thought that our universe is expanding at an ever-accelerating rate. But could we have that wrong? That is what a group of scientists from South Korea claims, but other scientists have ...

The universe's expansion may actually have started to slow rather than accelerating at an ever-increasing rate as previously thought, a new study suggests. "Remarkable" findings published today in ...

After a century of observations spanning the breadth of the cosmos and theoretical insights that push humanity's vision of the universe to its utmost limits, we can finally, confidently say that the ...

In 2022 three scientists won the Nobel Prize in Physics for proving something astonishing: the universe is not locally real. In other words, particles don’t have fixed properties until they are ...

The universe may have been born out of nothing, with an "anti-universe" twin where time runs in the opposite direction—rather than exploding from an infinitely small and dense point, or "singularity." ...

WASHINGTON, Dec 9 (Reuters) - Fresh corroboration of the perplexing observation that the universe is expanding more rapidly than expected has scientists pondering the cause - perhaps some unknown ...
