A new theory suggests our universe and a time-reversed twin could emerge together. This quantum approach avoids singularities ...

Dark energy is the mysterious force driving the accelerating expansion of the universe, and cold dark matter refers to the mysterious, invisible substance that provides most of the mass of almost ...

Teleology is the idea that some processes in nature are directed toward a goal or an end. Today, it is commonly asserted that ...

The finest ever map of the cosmic microwave background - the faint evidence of the universe's early form - has yielded ...

The groundbreaking findings throw established science into question, write Bernard J.T. Jones, Licia Verde, Vicent J.

The Atacama Cosmology Telescope (ACT) collaboration, which includes researchers from the University of Toronto, recently ...

suggest that the unknown force accelerating the expansion of the universe isn't what we believed it to be. This hints that our best theory of the universe's evolution, the standard model of ...

Cosmic microwave background data support cosmology’s standard model but retain a mystery about the universe’s expansion rate.

One element in that model, the Hubble constant, describes how fast the universe is expanding, but over the last half-century measurements of the constant have starkly disagreed, an inconsistency ...

Theoretical physicists James Hartle and Stephen Hawking, for example, proposed that rather than having a strict beginning as we would understand it, the universe evolved out of a "no-boundary" state ...

This model has explained a wide variety of ... is a difference in measuring the present-day expansion rate of the universe, a number known as the Hubble constant. Probes of the distant, early ...
