Our best model of the universe is called lambda-cold dark matter (LCDM), which splits the cosmos into three parts: the matter we can see, the matter we can’t see that still has a gravitational ...

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 ...

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 ...

Our current model for the early universe is known as the "hot Big Bang." It describes the first stage of our universe as a primordial fireball composed of a very hot plasma, much like our sun.

Let’s start at the beginning. Let’s talk about the standard model of the universe. Wendy, what is the standard model? WENDY FREEDMAN: Our standard model is a model in which the universe is expanding, ...

The Black Hole Universe: New Model Suggests The Big Bang Was Not The Beginning Of Everything. Complete the form below to listen to the audio version of this article.

And according to Pathria (1972), the universe might even sit inside a rotating black hole from a larger universe. More than just a philosophical idea, the rotation model affects how far-off ...

“This new evidence is suggesting that our Standard Model of the universe is holding up,” said Dr. Wendy Freedman, who is a John & Marion Sullivan University Professor of Astronomy and Astrophysics at ...

HETDEX is also focused on sound waves from the universe's first 400,000 years, which it says created by disturbances in a dense soup of hot particles of energy and matter.

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

The new model forgoes the need for either dark matter or dark energy as explanations for the universe's acceleration and how structures like galaxies are generated.. The researcher's work builds ...
