A further assumption, similar to but distinct and independent from homogeneity, is that the universe is also isotropic, meaning it has no preferred directions.

The James Webb Space Telescope (JWST), launched in 2022, continues to reshape how we view the cosmos. Designed to look deeper into space and further back in time than any previous instrument, it has ...

Does the universe behave the same way everywhere? Gravitational lenses could help us find out A JCAP study proposes a test for the Cosmological Principle using weak gravitational lensing ...

The Universe is currently flat or nearly flat, according to Marius Sparn, a PhD student at Kirchhoff-Institut für Physik. But at the beginning of its existence, it might have been more positively ...

“The isotropic universe assumption has noticeable benefits,” said Ó Colgáin, a physicist and data scientist based at Atlantic Technological University. “On one hand, it makes gravity ...

James Webb Space Telescope Reveals That Most Galaxies Rotate Clockwise This preferred direction of spin might be due to one of two reasons: either our entire universe exists in a black hole, or ...

Still, the universe extends for tens of billions of light-years in every direction, and so does the cosmic web, even if there might be the occasional clump we can’t quite explain yet. ORIGINALLY ...

In other words, the observable Universe is homogenous and isotropic. The second point is that spacetime is flat. If spacetime weren’t flat, our view of distant galaxies would be distorted, ...

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead suggesting giant voids in space are creating an illusion.

A methodology using weak gravitational lensing is proposed to test the Cosmological Principle, which assumes the universe is homogeneous and isotropic. This approach, ...

Feb 11, 2025: Does the universe behave the same way everywhere? Gravitational lenses could help us find out (Nanowerk News) “The cosmological principle is like an ultimate kind of statement of ...
