The standard model today holds that “normal” matter — the stuff that makes up people and planets and everything else we can see — constitutes only about 4 percent of the universe.

The standard model says that, after the Big Bang set the universe’s expansion in motion, the gravitational attraction between atoms first led to the formation of stars and galaxies, while also ...

Lieu's improved model doesn't rely on exotic phenomena like "negative mass" or "negative density" to work. The theory offers instead the notion that the universe is expanding due to a series of ...

The most widely accepted theoretical model, the Lambda/Cold Dark Matter model (ΛCDM), says the universe is growing at 67-68 km/s/Mpc. But what astronomers see through their equipment is a little ...

The universe’s timeline. Nasa/wikipedia, CC BY-SA. As the radiation is very old, when we make measurements of the CMB today, we are learning about the conditions of the early universe.

‘Shocking’ results from a major astronomical study have raised doubts about the standard model of cosmology, forcing scientists to consider new ways of understanding dark energy and gravity ...

In the new studies, astronomers pointed JWST's near-infrared camera (NIRCam) at the galaxy cluster PLCK G165.7+67.0, also ...

Aristotle and Ptolemy’s combined vision held such sway, in fact, that by the 14th century, Italian poet Dante Alighieri structured the world of his Divine Comedy around it. And all he had to do ...

The universe may end in a 'Big Freeze,' holographic model of the universe suggests. Huge cosmological mystery could be solved by wormholes, new study argues. Black hole singularities defy physics.

The Standard Model is the modern physical understanding of three of the four forces of nature: electromagnetism, the strong nuclear force and the weak nuclear force.

Findings from a new study into the cosmic "afterglow" may rewrite the history of the universe, according to researchers. This afterglow—the "cosmic microwave background" (CMB), the relic ...

New observations of the cosmos show that the dark energy, a mysterious force that accelerates the expansion of the universe, is evolving.
