The way particles interacted while the universe was forming seconds after the Big Bang could explain why the universe exists the way it does – a physicist explains matter-antimatter asymmetry.
Calabi-Yau manifold: a proposed structure of extra dimensions of space in string theory.
Good questions guide good science, but that doesn’t mean we know where we’ll end up.
When two particles are entangled, the state of one is tied to the state of the other.

A multitude of experiments have shown the mysterious phenomena of quantum mechanics to be how the universe functions. The scientists behind these experiments won the 2022 Nobel Prize in physics.
If time travel were possible, it would mean the existence of parallel timelines.
Scientifically speaking, for time travel to exist, so must parallel timelines. This theory addresses the paradoxes that arise when studying the possibility of time travel.
Measuring the mass of W bosons took 10 years – and the result was not what physicists expected.

A decadelong experiment produced the most accurate measurement yet of the mass of W bosons. These particles are responsible for the weak force, and the result is more evidence for undiscovered physics.
Faster than light travel is the only way humans could ever get to other stars in a reasonable amount of time.

If humanity wants to travel between stars, people are going to need to travel faster than light. New research suggests that it might be possible to build warp drives and beat the galactic speed limit.
Bending space into warp bubbles to travel faster than light may never be a reality, but distorting the flow of time just might be possible.
New mathematics have shown that lines of energy can be used to describe the universe.

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.
Philosopher Nick Bostrom’s theory suggests there’s a one-in-three probability we live in a simulation.
“We’re all mad here.”
“Sometimes I’ve believed as many as six impossible things before breakfast.” To understand the universe, we need more Mad Hatter mathematicians.
Hawking had a cult-like following among academics and non-academics alike.
Stephen Hawking was a highly creative scientist, pushing past assumptions and playing with “what if” scenarios to take physics to new levels.
British theoretical physicist and cosmologist, Professor Stephen Hawking in 2014.
Stephen Hawking inspired people with his work on black holes and other mysteries of the universe. Many were quick to pay tribute to the theoretical physicist who died today in the UK, aged 76.
Things are kind of different on the quantum level.
Forget solid, liquid, gas. This research used advanced math to theorize about topological phases of matter. And over the years experiments with matter and cold atoms have been validating the ideas.
Can the arts be a bridge to other worlds?
Is a novella published 130 years ago our best bet for explaining the worlds of 4D and beyond?
Isaac Newton was the most famous Lucasian Professor, but many other colourful figures have also occupied ‘Newton’s Chair’.
Some of history’s most brilliant scientists have occupied the Lucasian Chair, including Newton, Dirac and Hawking. Others were not so stellar.
If kitty goes in, will she really be alive and dead?
It’s a century-old debate: what is the meaning of the wave function, the central object of quantum mechanics? Is Schrödinger’s cat really dead and alive? I was recently involved in an experiment conducted…
We know gravity waves exist but just haven’t detected any… yet.
Our unfolding understanding of the universe is marked by epic searches and we are now on the brink of discovering something that has escaped detection for many years. The search for gravity waves has been…
Electricity – just one bright idea to stem from physics.
AUSTRALIA 2025: How will science address the challenges of the future? In collaboration with Australia’s chief scientist Ian Chubb, we’re asking how each science discipline will contribute to Australia…
Plotting world domination.
There are not many professions where people routinely ask you to justify your work, but theoretical physics is one of them. In the wake of the recent Nobel Prize to Peter Higgs and François Englert for…
Universe’s secrets are revealed in a dark corner in Switzerland.
Five years ago, at breakfast time, the world waited anxiously for news from CERN, the European Organization for Nuclear Research. The first nervy bunch of protons were due to be fired around the European…
