A mysterious force called Dark Energy might be changing, in a way that challenges our current understanding of the nature of ...

The shape of the universe is not something we often think about. My colleagues and I have published a new study that suggests ...

Scientists have discovered a giant cosmic filament where galaxies spin in sync with the structure that holds them together.

But the Big Bang theory predicts that about 5% of the universe's contents should be atoms made of protons, neutrons and ...

A team of astronomers using a variety of ground and space-based telescopes including the W. M. Keck Observatory on Maunakea, Hawaiʻi Island, have made one of the most precise independent measurements ...

By studying tiny distortions in the shapes of distant galaxies, scientists mapped dark matter and dark energy across one of the largest sky surveys ever assembled. Their results back the standard ...

By studying faint distortions in galaxy shapes across a vast region of sky, scientists probed the hidden structure of the universe. In the standard picture of the universe, nearly everything is hidden ...

Nature speaks to theoretical physicists to explore the real theories that inspired the hit series. Warning: contains spoilers ...

The universe's expansion is similar to a balloon inflating; the surface expands, causing dots (galaxies) to move apart. Galaxies farther away from us appear to recede faster than closer ones. The ...

Why is the shape of the universe depicted as a cone? If the universe is expanding with all points moving away from each other, how come it is depicted as cylindrical with the expansion outward mostly ...
