Gravity of a white dwarf star warps space and bends the light of a distant star behind it.

Astronomers report the first ever measurement of light bending around a star other than our own.
When black holes collide, gravitational waves are created in space itself (image is a computer simulation).

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.
Because everyone is different, psychologists have long debated how to characterise personality.
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.
Children are natural scientists. They learn from their mistakes, then try something new.
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.
It’s time for Africa to produce the technology it needs, rather than being largely a consumer.
Africa has deep-rooted problems: poverty, disease, corruption and war. Could these be solved through mathematical science?
Is there a Dr in the house?
It is possible – with just a couple of awkward provisos.
Einstein claimed that, had he not pursued science, he would have been a musician.

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 part in investigating the universe.

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.
This is a new era of physics and astronomy - and scientists all over the globe, including in Africa, have a role to play.
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.
Oh hey, I heard ripples in space and time, generated as two black holes merged. Call me back.
Here's a LIGO insider's description of how he got the news of a phenomenon that had first been theorized 100 years ago.
Computer simulation of two merging black holes producing gravitational waves.
If you understand how a trampoline works, you'll be able to understand what gravitational waves are.
Stick with me and I’ll show you the universe. Artist’s impression of LISA Pathfinder.
Why the LISA pathfinder mission, just about to launch, could revolutionise astronomy forever by giving us a completely new window into the universe.
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.
General relativity isn’t only a powerfully descriptive theory, but there’s a beauty in its elegance.
Einstein's theory of general relativity is a triumph of reason and imagination, of art and science, with a profound beauty of its own.
The fathers of modern physics, including Einstein, Millikan, Planck and others, in debate.
Physicists are working hard to unite Einstein's theory of relativity with quantum mechanics. It's no easy task.
Struggle to understand modern physics? Blame Einstein.
Space, time and space-time: it's all relative.
