The detection of gravitational waves is the final confirmation of Einstein’s theory of general relativity, and opens up a new window into the cosmos.
It takes something as stupendous as the merger between two black holes to generate detectable gravitational waves. Here’s how such incredible cosmic objects form.
It is the physics discovery of the century – even bigger than the Higgs Boson. Here’s how it happened and what it means, by a key member of one of the lead teams
Space, time and space-time: it’s all relative.
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.
We talk about mass all the time but what is it that actually gives an object mass? And why do some things have mass and others have no mass at all?
A new study has failed to find evidence of gravitational waves, but that doesn’t mean Einstein was wrong about their existence.
Plants on the International Space Station must figure out how to grow in a completely novel environment. Their adaptability hints at how they’ll react to changes here on Earth – or in future space outposts.
Einstein’s theory of gravity says dark energy must be out there, accelerating the expansion of our universe. But what is it and how can we try to figure out more about it?
I’d like to say that it’s not every day you get asked to try to break a world record with a speed-obsessed truck mechanic from Grimsby, but for us at the Centre for Sports Engineering Research it’s starting…
Millions of asteroids of all shapes and sizes are littered throughout the inner solar system. In the past three decades, scientists have spotted as many as 500,000 but many more remain unseen. Many of…
The huge success of Alfonso Cuarón’s Gravity at this year’s Oscars is a genuine cause for celebration for much of the UK film industry – not least for the many visual effects artists involved in its creation…
Think back to high-school science. Do you remember what the value of acceleration due to gravity at the Earth’s surface - denoted as “g” in textbooks - is? For those whose memories may need a bit of prodding…
School students today are taught physics based on obsolete theories and outmoded ways of thinking. Instead of the truth, most learn a naive simplification - the 300 year-old Newtonian physics, itself based…
Scientists have used gravitational measurements from the low-flying Goce satellite to map the boundary between the earth’s…
I have spent almost 40 years trying to detect gravity waves. When I started there were just a few of us working away in university labs. Today 1,000 physicists working with billion-dollar observatories…
Researchers have developed, for the first time, a method to efficiently produce long-lived “positronium” – a bound state…
Occasionally, very occasionally, a discovery comes along that reshapes our view of the universe. Some discoveries teach us about ourselves; some teach us how to better interact with the world around us…
The detection of gravitational waves has become more precise. Scientists used a quantum physics instrument to “squeeze” light…
