Unlike the current model—which the paper refers to as the Hot Big Bang (HBB)—this proposed theory “bounces” between a hot, ...

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 ...

In the wake of bombshell findings that suggest dark energy might be weakening as the universe expands, physicists are considering replacing the standard cosmological model of the universe with ...

The model is based on a solution to Einstein’s general theory of relativity (our best understanding of gravity) that assumes the universe is homogeneous and isotropic on large scales – meaning ...

For that reason, Ishak argues it's time for scientists to update their understanding of the universe. "Is it just [that] we are missing something big in the model of our universe and we just don't ...

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 on ...

This mismatch, known as the Hubble tension, has shaken confidence in the model that’s long explained how the universe behaves. Now, a new study proposes something bold. What if the universe isn ...

and others to test existing mathematical models of the universe. "When we have better and better maps, we can do a better and better job at figuring out that model and figuring out whether it's ...

Researchers have found that a hypothetical form of dark energy may lead to a grim fate for the universe: a "long freeze" where everything just…slows down. In this scenario, the universe would ...
