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 ...

But Cellarius’s magnificent rendering of the geocentric cosmos endures ... Danish astronomer Tycho Brahe’s model, in which most of the universe orbits the Earth, but the other five known ...

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 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 ...

One of the challenges in doing so is that the model does help explain many other elements of the universe with high certainty. “The Hubble constant is one of the basic constants that you can put ...

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 ...

the latest ACT results are a testament to the surprising durability of the standard model of cosmology and to the power of the CMB measurements to probe everything from the birth of the universe to ...
