The universe may be asymmetric, not identical in all directions The cosmic dipole anomaly challenges the standard Lambda-CDM ...

But there are several important anomalies, including a widely debated one called the Hubble tension. It is named after Edwin ...

A mysterious cosmic blast 1.3 billion light-years away has left scientists stunned. What began as a familiar stellar event ...

The shape of the universe is not something we often think about. But my colleagues and I have published a new study suggests it could be asymmetric or lopsided, meaning not the same in every direction ...

Astronomers know the universe is expanding, and that its rate of expansion is continually accelerating. Most explanations rely on “dark energy” to explain this phenomenon, but a new study takes a ...

Observations show that the Cosmic Microwave Background (CMB) contains tiny variations at the 10-5 level around its black-body equilibrium temperature. The detection of these temperature f luctuations ...

Scientists are using cosmic distortions in light to test a bold idea: that the Universe might not be as symmetrical as we’ve long believed. If Euclid detects the right kind of patterns, it could ...

In 1937, P. Dirac proposed a new basis for cosmology: the hypothesis of a variable gravitational “constant” G [5]; and later (1974) added the notion of continuous creation of matter in the World [6].

For a long time, scientists have believed that the universe looks the same no matter where you are or which direction you look. This idea, called the Cosmological Principle, is a key assumption in ...
