The shape of the cosmos depends on a balance of two competing forces: the pull of gravity and the expansion driven by dark ...

Faint structures play a crucial role in cosmic development, and scientists are only just beginning to grasp their full extent ...

It's well established that the universe is expanding, but there's serious disagreement among scientists over how fast it's ...

Neutrino particles have extremely small masses, yet there are so many of them that they carve out the large-scale structure ...

Mathematics and physics share a close, reciprocal relationship. Mathematics offers the language and tools to describe physical phenomena, while physics drives the development of new mathematical ideas ...

The shape of the universe has been puzzling scientists for decades, and some new theories suggest it might not be the flat or spherical shape we’ve assumed, but something far more egg-like. While ...

So cosmologists feel confident in modelling the universe using the “maximally symmetric” description of space-time in Einstein’s theory of general relativity. This symmetric vision for the universe, ...

For measuring curvature of 3D (hyper) surface we need solid angles instead of plane angles. General relativity (GR), which explains events on the greatest cosmological scale, and quantum mechanics (QM ...
