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 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 ...

Instead, we should think of our Universe as if it were the surface of the Earth: we can move in any direction without ever reaching an edge, but there is no center on the surface.

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 ...

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.

“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 ...

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, ...

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 ...

A new hypothesis suggests that the universe may be twice as old as we had believed. Observations from the James Webb Space Telescope provide new information on the rate of the universe’s expansion.

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