The Big Bang model begins with a point of infinite density where the laws of physics break down. This is a deep theoretical problem that suggests the beginning of the Universe is not fully understood, ...

String theory has long been presented as physicists' best candidate for describing the fundamental nature of the Universe.

The Big Bang may mark an end—not the start—of a previous universe's aeon. Penrose's theory sees the universe as an eternal ...

What we saw in the DESI experiments, and now strengthened by our South Pole Telescope observations, is that dark energy is ...

From four-dimensional hexagons to the mind-bending amplituhedron, geometrical shapes are wilder than we learn at school - and ...

A festinating new theory shifts focus from space to time, arguing the clock-ticking we take for granted is richer and weirder ...

From living matter to molecules to elementary particles, the world is made of “chiral” objects that differ from their ...

Big Bang almost sounds like a theory of creation, as if God or some almighty power… Yes. That’s why many people like it. And that’s why many people question it. Yes, so we said that instead, why not ...

Scientists propose a new theory to solve the Hubble tension. The universe might be rotating very slowly. Istvan Szapudi suggests this cosmic spin could explain inconsistencies in expansion ...

In this text, we explore a theory suggesting that the universe is finite and without edges—a concept explained by its possible toroidal (donut-like) shape. Homer Simpson’s “Proposed” Donut ...

Wendy Freedman: We didn’t know the age of the universe to better than a factor of two. Was the universe 10 billion years old or 20 billion years old? Paul Rand: That’s Wendy Freedman, professor of ...

A theory known as non-singular matter bouncing cosmology suggests that the universe “bounces” between a hot big bang era and the kind of universe we see today.
