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 ...

And they had noticed that Ptolemy's geocentric model of the universe, it wasn't matching the math. Over the next few decades, Copernicus calculated and recalculated and re-recalculated the heavens ...

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 result, alongside other measurements of the early universe, aligned with predictions made by the standard model of cosmology. But it has been swiftly contradicted by Cepheid distance ladder ...

Vacuum catastrophe aside, dark energy now forms one of two central pillars of the standard model of cosmology, the best scientific description of the universe’s evolution. The other pillar is ...

Scientists from Hungary and the USA have proposed a new model suggesting that the entire universe could be rotating. This concept could solve the problem known as the Hubble tension, concerning ...

The new study takes aim at a key assumption of the standard model: that the universe is homogeneous and isotropic on large scales, meaning it looks the same in every direction and from every ...

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 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 ...
