It's all about the strong gravitational field of the black hole.
Exactly 99 years after Einstein's theory of general relativity was proven right in our own solar system, scientists show that it also holds true for entire galaxies.
Jets from supermassive black holes behave in mysterious ways. Now scientists have now worked out what's really going on.
Astronomers report the first ever measurement of light bending around a star other than our own.
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 famous theory of general relativity theory lives on thanks to new research.
Both genetic and environmental factors determine someone's personality. Genes account for between 30-50% of the determination and unique environmental experiences making up the rest.
Scientists being wrong is not a bug or a glitch – it's a feature of science and mistakes can actually lead to new, deeper discoveries.
Africa has deep-rooted problems: poverty, disease, corruption and war. Could these be solved through mathematical science?
It is possible – with just a couple of awkward provisos.
Einstein, an accomplished violinist, claimed that, had he not pursued science, he would have been a musician. That's worth reflecting on, in the wake of last week's discovery of gravitational waves.
Music has always played a role in our understanding of the universe. Listening to gravitational waves confirms thousands of years of metaphysical investigation.
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 has ushered in a new era in astronomy and physics. Where will the next big discovery be made? There's no reason for it not to be Africa.
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.
Here's a LIGO insider's description of how he got the news of a phenomenon that had first been theorized 100 years ago.
If you understand how a trampoline works, you'll be able to understand what gravitational waves are.
Why the LISA pathfinder mission, just about to launch, could revolutionise astronomy forever by giving us a completely new window into the universe.
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.
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.
