What could a ‘relativistic camera’ capture on the way to Alpha Centauri?
An astronomer suggests an idea to piggyback on the ambitious Breakthrough Starshot project that aims to send nano spacecraft to Alpha Centauri at a major fraction of the speed of light.
How fast can quantum computing get? Research shows there’s a limit.
A future that continues to have increasingly fast computing depends on quantum physics – but research is showing that there are limits to how fast quantum computers can go.
Einstein’s theories are still not taught in school.
Einstein's theories of relativity underpin our understanding of the universe, yet they're not taught in high school. How can we change that?
There's a good reason you should care about the discovery of gravitational waves, even if you don't understand the science.
A team effort: Dr David Reitze, of the LIGO Laboratory at Caltech, shows the merging of two black holes that led to the detection of gravitational waves.
The discovery of gravitational waves involved a team of more than 1,000 scientists from across the globe, including Australia. So how does such an international collaboration work?

It's taken centuries for our understanding of gravity to evolve to where it is today, culminating in the discovery of gravitational waves, as predicted by Albert Einstein a century ago.
Albert Einstein wrestled with unifying gravity with electromagnetism and quantum mechanics until his dying days.

After the triumph of general relativity, Albert Einstein spent the rest of his life chasing a unified theory, which eluded him right up until the end.
Hyperspace may one day be a reality.
Many people think relativity puts a hard speed limit on the universe, but it actually opens up the possibility of faster-than-light travel - if we can overcome some significant practical hurdles.
It’s possible that had Einstein not conceived of general relativity, then we’d still be at a loss to explain gravity to this day.
Special relativity was inspired, but it took true genius to conceive of general relativity. Had Einstein not come up with it, it may have taken decades for us to figure it out.
General relativity didn’t happen overnight, but took several steps to come to fruition.
This month is the centenary of the general theory of relativity. But how did we get from the absolutism of Newton to the relativity of Einstein?
I can get you there fast!
There's a cosmic speed limit that unfortunately means you aren't going to be firing up warp drive anytime soon.
Bigger inside, says science.
As Doctor Who’s 50th anniversary looms, time travel is everywhere – on the screen, at least. Famously, the Doctor can whizz through the years using a “dimensionally transcendental” machine, the TARDIS…
Hyper-drives might be the stuff of science fiction, but they could be science fact too.

Fans of science fiction must be disheartened when introduced to Einstein’s Special Theory of Relativity. Dreams of galactic empires, criss-crossed by roguish princesses and beautiful smugglers, go out…
