A new model of the Universe suggests that modifying Newton's theory of gravity could do away with the need for dark matter. The model instead relies on an as-of-yet undiscovered form of gravity to ...

A new mathematical model could resolve the Hubble tension by assuming the universe rotates. Related: After 2 years in space, the James Webb telescope has broken cosmology. Can it be fixed?

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 ...

based on the big-bang expanding universe concept. My research proposes a model that determines the universe's age to be 26.7 billion years, which accounts for the JWST's "impossible early galaxy ...

"In my model, I propose that our universe did not arise from a classical singularity, but instead emerged from a Euclidean phase through quantum mechanics," Kumar wrote. "The essence of the idea i ...

New findings risk turning the tension into ... This result, alongside other measurements of the early universe, aligned with predictions made by the standard model of cosmology.

Credit: MARK GARLICK/SCIENCE PHOTO LIBRARY via Getty Images Researchers have found that a hypothetical form of dark energy may lead to a grim fate for the universe: a "long freeze" where ...

The findings could undermine the existing standard cosmological model of the universe called the lambda-cold dark matter (LCDM) model, which takes dark energy, ordinary matter, and cold dark ...

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 ...
