Physicists may have got something fundamentally wrong about the world’s most essential particles. The truth could change our understandings of the Universe
Ghost detector: This new machine could reveal the Universe’s deepest secrets
Jiangmen Underground Neutrino Observatory (JUNO) is set to unlock the secrets of nature’s most elusive subatomic particle: the neutrino.
Something is wrong with our understanding of the Universe and the closer we look the weirder it gets
Our picture of the cosmos is incredibly detailed. But it's by no means complete. There are crucial pieces missing in the cosmic jigsaw. And without them the picture just doesn't make sense.
How one particle could soon rewrite our laws of gravity
If particles are what carry the force of gravity, those particles should be detectable… in theory.
The 7 biggest myths about your reality, busted by science
The world isn't what it seems. Here's how science has exposed the fallacies and misconceptions of Earth and the heavens throughout history.
Earth's magnetic field is overdue a flip. Should we be worried?
From time to time, the Earth's magnetic poles flip, leaving us without a protective magnetic field for up to centuries at a time.
This hidden ice base is mining the Antarctic for ghostly cosmic particles
Neutrinos are everywhere, yet they’re almost impossible to detect. Now, some of these ghostly particles have been picked up coming from the Milky Way for the first time.
What's inside the fifth dimension?
What else could there be beyond the three dimensions of space and one of time? And how can we begin to conceive of it?
How a simulation wormhole may unite gravity and quantum theory
Are physicists nearing in on the Holy Grail 'theory of everything'?
If the universe is expanding, how are the Milky Way and Andromeda getting closer together?
Recent data from Hubble suggests that the Universe is expanding at a rate of around 73km per megaparsec (3.26 million light-years).
What is on the other side of a black hole?
Not even light can escape a black hole.
Dark matter: Is it time we gave up looking for it?
After decades of searching for dark matter and coming up short, some researchers say we should take the possibility of a new theory of gravity more seriously.
These 4 signs of alien technology could lead us to extraterrestrial life
Pioneering scientists think we should start looking for extraterrestrials in a whole new way: by seeking out alien technology.
Project Galileo: The search for alien tech hiding in our Solar System
The search for alien life is ramping up. But what if, instead of searching for signs of biology, we looked for something more familiar: an extraterrestrial civilisation.
Superluminous supernovae: How we’ll find the most powerful explosions in the Universe
As new telescopes around the world power up, they could answer an ancient mystery: what’s powering the most energetic explosions in the Universe?
Where did all the antimatter go?
Some of our antimatter must be missing, given the amount of matter leftover in the Universe.
Why a theory of everything may never be possible – or any use
One theory to rule them all – is such a thing plausible? According to some physicists, it could cause more problems than it solves.
Does the universe have an edge?
It’s all very well saying the Universe encompasses everything, but everything has to end somewhere, right? Well, not exactly.
Inside the simple computer program that could explain why the Universe exists at all
Stephen Wolfram is trying to find a rule that dictates the Universe. And in doing so, he might even become the first person to finally devise a complete, fundamental theory of physics. Elegant, or what?
The cracks in cosmology | Why our Universe doesn't add up
In terms of our understanding of the Universe, some things just don’t add up. Which means either our measurements are wrong, or our theories are.
The Universe’s 7 biggest mysteries (and why they’re unsolved)
Dark matter, the nature of time, aliens and supermassive black holes: these seven things will be puzzling astronomers for years to come.
What was before the Big Bang? Everything you need to know

Neutrinos | The vital clue to a 'theory of everything'
Ninety years after its prediction and 25 years since the Nobel Prize was awarded for its discovery, the neutrino particle is still surprising us. It may, in fact, be the key to understanding everything.
