These ripples in the very fabric of the universe were hypothesized by Einstein a century ago. Now scientists have detected them for the third time in a year and a half – ushering in a new era in astrophysics.
It’s a lot of grains of sand, but numbers can get a whole lot bigger….
Scientific advances – including the recent discovery of gravitational waves – force us to deal with numbers so extreme they're virtually inconceivable.

Why gravitational waves from the birth of the universe are a whole different story than the waves LIGO detected.
A needle in a haystack? Pan Starrs telescope is scanning billions of galaxies to find the black holes emitting gravitational waves.
The hunt to find the source of the gravitational waves detected by LIGO on the sky is only just starting.
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.
A team effort: Dr David Reitze, of the LIGO Laboratory at Caltech, shows the merging of two black holes that led to the detection of gravitational waves.
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?

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.
All this time we were only observing some of gravity's most superficial effects. This discovery changes everything.
Massive bodies can send ripples through space time in the form of gravitational waves.
The long awaited discovery of gravitational waves has sent ripples through the scientific world. Here top experts respond to the historic announcement.
Extra, extra! The embargo’s lifted, read all about it.

Sometimes big research news bypasses the usual scientific publishing process. Here's why that's not good for scientists or the public.
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.
When two black holes collide, the resulting gravitational ripples can be felt across the cosmos.
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.
Binary black holes come in a variety of forms, but they are all astounding.

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.
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.
