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

To explore this long-standing mystery, an international team of scientists formed a group known as the Collaboration for ...

New research suggests the universe may be lopsided. Cosmic microwave background and galaxy data hint at directional differences, challenging cosmology’s assumption of uniformity and standard ...

It's an unintended consequence of the Atomic Age. Dan Smith shows how nuclear testing inadvertently affected steel production ...

So much happened in the earliest moments of the universe. Elementary particles appeared, the first nuclei of hydrogen and helium, and fluctuations of energy and matter set into motion the formation of ...

Scientists are reeling from an unexpected blow after news that a much anticipated future observatory—designed to decipher the earliest moments of cosmic history—won’t be able to proceed with its ...

LIGO confirmed the existence of gravitational waves in 2015, detecting one-time perturbations of spacetime from the merger of large black holes. There should be a background of gravitational waves ...

Gravitational waves are ripples in the fabric of spacetime predicted by Albert Einstein’s general theory of relativity, first detected in 2015. But an expected corresponding low-frequency ...

(via Sabine Hossenfelder) In the Big Bang Theory, the cosmic microwave background — microwave-range radiation that floats through the entire universe at a steady 2.7 Kelvin — is evidence that a hot ...

New research challenges the standard cosmological model, suggesting that the universe may be asymmetric or lopsided rather than uniform in all directions.

(via Dr. Becky) There's a strange, unexplained feature of the Cosmic Microwave Background which seems to be aligned with the Solar System, and we don't why. Is it real or just a coincidence? And if it ...

The cosmic microwave background, shown at left in this illustration, is a flash of light that occurred when the young universe cooled enough for electrons and protons to form the first atoms. It ...
