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 ...

She is known to have edited and improved Ptolemy's Almagest, a foundational astronomical text that described the geocentric model of the universe and included methods ... Her teaching drew from the ...

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 ...

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 assumption of constant dark energy is baked into the widely accepted Lambda-CDM model of the universe. In this model, only 5% of the universe is made up of the ordinary matter we can see.

In the years since then, scientists have remained in the dark about what’s causing the universe’s prolonged growth spurt (hence the name “dark energy”). To construct their standard model ...

Our latest and best ever map of the early universe is five times more detailed than anything we have had before, but while it precisely backs up the leading model of the universe, it is also a ...

Seleucus of Seleucia was among the first to argue for heliocentrism, supporting Aristarchus’ model of the Sun-centered universe ... The dominant geocentric model, championed by Aristotle and later ...

"The discrepancy between the observed expansion rate of the universe and the predictions of the standard model suggests that our understanding ... and the Christopher R. Redlich Fund.

"The Webb results can be interpreted to suggest there may be a need to revise our model of the universe, although it is very difficult to pinpoint what this is at the moment," said Siyang Li ...
