Scientists propose a gravitational-wave method called the stochastic standard siren to measure the Hubble constant, offering an independent way to examine the universe’s expansion and the Hubble ...

Last year, our most detailed map of the universe yet suggested our understanding of dark energy has been wrong for decades. The shock result is reigniting the search for a better cosmic story ...

Cosmic voids are different. These vast expanses contain very little matter. In such places, the vacuum of space-time itself becomes the dominant component. If you were positioned at the center of a ...

Astronomers have discovered the brightest and most distant "megamaser" to date. The cosmic energy beam is shooting toward ...

In this video, Kobi Brown examines misconceptions about the Big Bang theory and its role in our understanding of the universe ...

A closer look at the Lambda Cold Dark Matter model, its core components, supporting evidence, and why new observations are ...

Ripples in the fabric of space-time called gravitational waves may be the key to solving the Hubble tension — one of the biggest nagging problems in physics.

For decades, the Standard Cosmological Model has operated on a single, foundational assumption: the Big Bang happened everywhere at exactly the same time. Today, a newly released theoretical paper ...

There have been plenty of attempts to resolve the "Hubble Tension" in cosmology. This feature describes how one of the most important variables in cosmology, the expansion of the universe, takes on ...

Cosmologist L Sriramkumar said gravitational waves could help scientists understand what happened just fractions of a second after the Big Bang ...

For the last 25 years, most scientists have believed that about 70% of the universe is formed by something called ‘’dark ...

New 2026 research links coffee and tea to lower dementia risk, suggests dark matter may interact with neutrinos, and reveals ...
