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.

In a groundbreaking studypublished in the Monthly Notices of the Royal Astronomical Society, astronomers have uncovered a puzzling cosmic observation that challenges our understanding of the ...

Because the geometry of spacetime is shaped by the distribution of matter and energy, an isotropic universe must posses a geometric structure that looks the same in all directions as well.

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 humility ...

In the second, the universe is not isotropic, perhaps because dark energy is stronger in some parts of the universe than others. While other tests are needed to determine exactly what this study ...

Scientists have confirmed that we are officially lost in a universe that has no up or down, and no axis to rotate around. Oh good.

The conditions that allowed the Big Bang had to do with the Inflation of our proto-universe. Most of the generations that currently inhabit the planet have grown up under the idea that the universe ...

The theory contains an asymptotic cosmological Friedmann solution. The solution obtained turns out to be dynamically stable, so that it can form the observed properties of the Universe. New ...

We analyze the canonical quantum dynamics of the isotropic Universe with a metric approach by adopting a self-interacting scalar field as relational time. When the potential term is absent, we are ...

The trouble is that vector fields tend to “pick” a preferred direction in space and therefore ruin inflation’s biggest selling point. Mukhanov and colleagues have now overcome this problem by invoking ...
