An extreme laboratory in space involving three dead stars has shown that all objects really do accelerate identically, proving Einstein right.
Nearly 50 years since the first man walked on the moon, our morals are still stranded on Earth.
A team of astronomers captured the moment when a wayward star was pulled into the mouth of a supermassive black hole.
To answer this tricky question, we have to look back in time to when the Earth was born, 4.5 billion years ago.
Instead of pulling us to the top or bottom, the force of gravity pulls us to the middle of the Earth.
The famous cosmologist was closely identified with black holes due to his revolutionary theoretical work explaining some of their mysterious properties.
To stay up, the bird must overcome gravity with a force called ‘lift’.
No matter how cold it is, you’re lucky you don’t live on Venus.
Research suggests a new threat to life on Earth from the meteorite’s crash: Via seismic waves, the impact triggered massive undersea eruptions, as big as any ever seen in our planet’s history.
Imagine the Earth pulling everything it is made up of, all of its mass, towards its centre. This happens evenly all over the Earth, causing it to take on a round shape.
The latest reboot of The Mummy is all you should expect from a Hollywood blockbuster on an ancient Egyptian curse. But what about the science?
To get us to Mars and beyond, a team of students from around the world has a plan involving lunar rovers mining ice and a space station between the Earth and the moon.
Every moment of life on our planet has had the force of gravity in the background. But the prospect of long-distance space travel means it’s time to figure out what happens to our biology in its absence.
The discovery of a new black hole adds to our understanding of these celestial objects that fascinate in both fact and fiction.
One of the great mysteries of the universe is why there is so much more matter than antimatter. Now a new experiment is helping us understand the nature of antimatter better than ever before.
Einstein’s theories of relativity underpin our understanding of the universe, yet they’re not taught in high school. How can we change that?
Why weightlessness in space is about balancing forces rather than a lack of gravity.
There’s a good reason you should care about the discovery of gravitational waves, even if you don’t understand the science.
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?
