We seem to have established the basic parameters describing the behaviour of our expanding Universe, ... (CP) is the assumption that, on large scales, the Universe is homogeneous and isotropic.

The assumption that the universe is isotropic – or the same in all directions – has underpinned the rest of our understanding of where the cosmos came from, and where it may be going.

IT is often assumed that quasars are partaking in the general expansion of the substratum of an isotropic universe. This hypothesis requires that those quasars possessing any particular ...

“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 ...

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.

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

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

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 ...

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.
