Field theory describes the universe as energy flowing along unending lines. With this perspective, it is possible to define a new fundamental building block of matter.

Dark energy is probably a sea of constant energy in empty space itself, according to new research.
Cosmologists had only been able to find half the matter that should exist in the universe. With the discovery of a new astronomical phenomenon and new telescopes, researchers just found the rest.
The term ‘Big Bang’ might make you think of a massive explosion. Put the thought out of your head. Rather than an explosion, it was the start of everything in the universe.
Thirty years ago the Hubble Space Telescope began snapping photos of distant stars, providing a time machine that has taken astronomers back to when the universe was less than a billion years old.
New research using the Hubble Space Telescope reveals that galaxies may be forming at faster rates than previously believed.
A study has suggested that the universe is curved like a sphere rather than flat, which may unleash a major crisis in cosmology.
Dark sky sites can inspire new generations of stargazers, but a better long-term solution would be connecting people with the night sky where they live.
Maps of the long filaments of gas that hold the universe together may one day help us trace and unveil ‘dark matter’.
The rate of the universe’s expansion is in dispute. But a new kind of measurement offers hope.
In an age when women were rarely allowed in observatories, Margaret Burbidge changed how we saw the stars.
When you look at the squiggly lines on Joy Division’s famous album cover, you’re seeing a record of lightning in outer space.
Gravity exists because the universe is full of ‘stuff’ – here’s how it came to be.
The diameter of the Milky Way is a billion billion kilometres.
At the end of the day, the problem is that no-one on Earth wants nuclear waste stored near them, and it’s not safe or cost-effective to blast it into space.
Long ago in the distant past, our entire Universe was microscopic – just like an atom – and obeyed completely different rules of cause and effect.
Our brain cells do look a lot like a map of the universe – but that doesn’t mean they’re the same thing.
“Sometimes I’ve believed as many as six impossible things before breakfast.” To understand the universe, we need more Mad Hatter mathematicians.
Astronomers are voting to rename one of the laws of physics. The voting may have far-reaching effects leading to renaming of other laws and giving ‘forgotten’ scientists due credit.
