A team of physicists have proposed a new cosmological model – dubbed the "black hole universe" – that suggests that our universe did not begin at the Big Bang. For a long time the universe was assumed ...
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 ...
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.
Universe may revolve once every 500 billion years — and that could solve a problem that threatened to break cosmology One idea is known as holographic dark energy. In this scenario, gravity ...
The chances of intelligent life emerging in our Universe -- and in any hypothetical ones beyond it -- can be estimated by a new theoretical model which has echoes of the famous Drake Equation.
A new hypothesis from physicists at the University of Portsmouth in the U.K. challenges the long-standing Big Bang Theory as the ultimate origin of the universe. This new “Black Hole Universe ...
The findings could undermine the existing standard cosmological model of the universe called the lambda-cold dark matter (LCDM) model, which takes dark energy, ordinary matter, and cold dark ...
So we have this model that there is dark energy that’s making the universe expand faster and faster. It accelerates in its expansion. But just this last year, various teams have started measuring that ...
The universe seems to be spinning, and that could explain what dark energy is and why it's weakening while revealing our place within the multiverse.
In 1508, Nicolaus Copernicus developed a celestial model of a heliocentric planetary system that transformed the way we view the universe. This bold theory, contrary to the geocentric model ...
The universe expands over time, but how fast it’s expanding seemed to differ depending on whether you looked early in the universe’s history or the present day. If true, this would have presented a ...
