Astronomers have spotted runaway black holes screaming through space, leaving trails of stars in in their wake.

In trials teaching Einsteinian physics in schools, our most astonishing discovery was that children were not astonished: they just took the ideas in their stride.
A small add-on to existing gravitational wave detectors could reveal what happens to matter as it becomes a black hole, a process like the big bang in reverse.
There is a reason why it’s easier to roll marbles down rather than up a hill. And the answer (to this and to gravity itself) is all about acceleration.
Keengganan pemerintah untuk berinisisiatif menurunkan emisi global merupakan tanda bahwa kita memerlukan solusi-solusi nyata di berbagai sektor untuk menangani krisis iklim.
The lack of progress by governments in reducing global emissions means bold solutions across multiple fronts are now needed.
More ripples in space-time have been detected from merging pairs of black holes, one of which was the most massive and distant gravitational-wave source ever observed.
Out there in space there is no air. If you took your helmet off, all the air you need to breathe would whoosh out.
From a slow hum to a chirp or a bleep, what is that sound you hear whenever there’s a new detection of gravitational waves?
Astronomers have finally confirmed the source of the latest detected gravitational waves was the collission of a pair of neutron stars, what they’d been searching for all along.
Einstein called entanglement “spooky action at a distance”. But now it’s been used to design an incredibly sensitive detection method for gravitational waves.
Einstein’s theories of relativity underpin our understanding of the universe, yet they’re not taught in high school. How can we change that?
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.
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…
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…
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…
Detecting gravity waves is a major goal for astrophysicists. We know they should be there, but we haven’t found them yet. But today we are one step closer. By literally squeezing light on a quantum level…
