The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study ...

In an unprecedented step, researchers crafted a detailed model compatible with the universe’s accelerated expansion.

Our universe is expanding at an ever-accelerating rate — a phenomenon that all theories of cosmology agree upon but none can fully explain. Now, a new theoretical study offers an intriguing solution: ...

In the strange world of quantum mechanics, objects can exist in several states at once. This concept, called superposition, is one of the most puzzling features of quantum theory. A particle, for ...

Astronomers have proposed a new theory to suggest why our universe is expanding at an accelerating rate. That our universe is expanding is in wide agreement, though how exactly that process happens is ...

Google on Monday announced Willow, its latest, greatest quantum computing chip. The speed and reliability performance claims Google’s made about this chip were newsworthy in themselves, but what ...

There may be another universe just a millimeter away from ours, hovering in an extra, hidden dimension. At any moment this second universe (or “membrane,” in M-theory—a relative of superstring theory) ...
