We’ve been told by science that the universe is expanding relentlessly, driven by a mysterious force called dark energy.

The shape of the cosmos depends on a balance of two competing forces: the pull of gravity and the expansion driven by dark ...

New data from major dark-energy observatories suggest the universe may not expand forever after all. A Cornell physicist calculates that the cosmos is heading toward a dramatic reversal: after ...

Earlier this week, science writer Paul Sutter covered a bold new study that leans toward so‑called “fuzzy” dark matter as the ...

Physicist Sean Carroll explains how physics, astronomy, philosophy, and classics all help us understand the expanding ...

Our universe does host life, but another one might be even better suited for life. Here’s what you’ll learn when you read ...

You might think galaxies can’t ever find each other in our runaway cosmos, but it turns out gravity can sometimes overcome ...

They shaped the Universe, yet the first stars ever born continue to evade the searches of astronomers like Dr Emma Chapman ...

The fate of the cosmos may be a bit different than previously expected. For years, scientists have talked about how the universe is always expanding — constantly moving outward, never stopping.

The earliest black holes in the universe may not have disappeared from Hawking radiation after all, new research hints. Instead, they fed on the energy of the ancient cosmos to grow supermassive.

Astronomers have produced the most detailed map yet of dark matter, revealing the invisible framework that shaped the Universe long before stars and galaxies formed. Using powerful new observations ...
