Mind-Blowing New Theory Connects Black Holes, Dark Matter, and Gravitational Waves

The past few years have been incredible for physics discoveries. Scientists spotted the Higgs boson, a particle they’d been hunting for almost 50 years, in 2012, and gravitational waves, which were theorised 100 years ago, in 2016. This year, they’re slated to take a picture of a black hole. So, thought some theorists, why not combine all of the craziest physics ideas into one, a physics turducken? What if we, say, try to spot the dark matter radiating off of black holes through their gravitational waves? Read More >>

Why Is This Quasar Running Away From Such a Handsome Galaxy?

We don’t understand quasars all that well, but are pretty certain that these incredibly bright lights belong in the centres of galaxies. So it looked a little weird when astronomers spotted quasar 3C 186 thirty six thousand light years away from the centre of its galaxy, seemingly trying to escape. Read More >>

Scientists Are Turning Earth Into a Telescope to See a Black Hole

Black holes may be one of the universe’s most bizarre phenomena. They’re literally divide-by-zeros in the sky, places where the mathematics of Albert Einstein’s theory of general relativity falls apart. These dense behemoths have such strong gravitational fields that time stops, and all futures point directly at the centre, and light crossing the boundary, or event horizon, can’t escape. But no one’s ever taken a picture of a black hole, and scientists want to change that. Read More >>

A Wild New Hypothesis for How the First Monster Black Holes Formed

It’s no secret that supermassive black holes are heartless beasts: These objects of immense gravity that let nothing, not even light escape, have fascinated astronomers since the early 20th century. While it’s believed that so-called supermassive black holes lurk at the center of most galaxies, including our own, there’s still much we don’t know about how they formed, or why, except to remind us of our own mortality.

Here’s A Black Hole Gif To Put All Your Problems In Perspective

If you need to feel insignificant and ineffectual this Monday morning, we've got just the gif. Read More >>

How Tiny Would Donald Trump’s Hands Be If They Were Black Holes?

Let me tell you a little something about gravity: It’s weird. A hundred or so years ago, Albert Einstein realised Isaac Newton’s laws didn’t work so well for really extreme situations, ones Newton never would have encountered on 17th century Earth. So Einstein said, alright, let’s come up with a new theory that looks like Newton’s theory, but also works for really big things and really fast things like planets and light—called general relativity. Einstein’s theory says mass causes the shape of space and time to change. Read More >>

Black Holes May Be Way More Murderous Than We Realised

Don’t get me wrong, black holes are cool but they’re also giant voids of terror: these gravitational abysses have been known to snack on stars in occurrences called Tidal Disruption Events (TDEs). It’s always the same horror story — an unsuspecting star wanders too close to a black hole, only to get ripped apart by the black hole’s gravity. Isn’t space pleasant? Read More >>

Drone Footage of a Draining Dam Looks Like Flying Into a Black Hole

To prevent massive dams from overflowing when heavy rains cause water levels to rise, spillways like this are used to drain water to the stream below. Without a true sense of scale, it looks just like the drain in your bath, but from a drone’s bird’s eye view, the opening to this spillway looks more like a black hole sucking everything in.

This Giant Black Hole Set a Record for Longest-Ever Lunch

A typical lunch outing with friends lasts about an hour-and-a-half. If it’s bottomless brunch, maybe tack on a few more hours. But supermassive black holes don’t care for our human constructions of time—it turns out they’ll eat for a decade if they choose. Read More >>

A New Method Could Reveal the Stealthiest Black Holes in the Galaxy

Black holes are the strong, silent type — an age-old enigma. Hubble estimates that there are roughly 100 million black holes in our galaxy alone, but because their gravitational pull is so intense, light can’t escape. So even with the most advanced equipment,“stray” black holes wandering in space are nearly impossible to find. Read More >>

Black Holes and Galactic Cluster Combine Into a Giant Cosmic Particle Accelerator

Two billion light years away, two clusters of galaxies are colliding in an intergalactic pileup. As black holes interact with the gas inside the collision, the mass has turned into an enormous particle launcher, spewing some of the universe’s highest-energy stuff. Read More >>

The Most Detailed View of Black Holes in the Universe are Mind Blowing

Stare into the abyss, my friends. The image above features the highest concentration of black holes humans have ever seen. So dense are the merciless chasms of darkness at the centre of this map, you could pack 5,000 of them into a patch of sky the size of the full moon. Read More >>

Brightest Supernova Ever Seen Was Actually Something Much Darker

Last year, astronomers recorded the brightest supernova explosion ever seen. Follow up observations now suggest this cataclysmic event wasn’t a supernova at all, but rather, an extremely rare celestial phenomenon involving a supermassive black hole and a rather unfortunate star. Read More >>

This Entire Galaxy is Being Ravaged By its Supermassive Black Hole

A stunning new image captured by the Hubble Space Telescope shows a galaxy that’s being strangled by tentacles of gas and dust. The strange and intricate shape of this celestial object is caused by a supermassive black hole at its core — and it’s killing the host. Read More >>

A Naked Black Hole is Screaming Through the Universe

Millions of years ago, B3 1715+425 was just an ordinary supermassive black hole. It had a comfortable life, of devouring stars and belching deadly x-rays, at the centre of its distant galaxy. Now, starless and alone, it’s screaming through space at 2,000 miles per second — and it may never stop. Read More >>
