The discovery sparks questions around the current existing standard cosmological model of the universe – the lambda-cold dark matter (LCDM) model – which includes hypotheses posed by Albert ...

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 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 ...

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 ...

In a new effort, physicists working on a non-relativistic dark fluid model say that if the universe is rotating then these discrepancies between the two measurements can be resolved. "To ...

Each gives a different value for the expansion rate. Szapudi's team developed a mathematical model of the universe. First, it followed standard rules. Then they added a tiny amount of rotation.

While this new work was a simulation of a simplified model of these dynamics, the findings can still shed light on what may one day happen in our own universe. This Strange Stuff May Be Older Than ...

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 ...

The findings bring astronomers another step closer to unmasking the mysterious nature of dark energy, which may mean that the standard model of how the universe works could also require an update ...
