Next-Gen Telescopes Could Detect the First Black Holes
The first black holes to appear in the universe may have formed from the direct collapse of gas. When they collapsed, they released a flood of radiation, including radio waves. A new...

What If the Universe Had No Beginning?
In the beginning, there was … well, maybe there was no beginning. Perhaps our universe has always existed — and a new theory of quantum gravity reveals...

Are the Remnants of the First Stars all Around Us?
The first stars to appear in the universe lived fast and died young. Today, none of them likely remain. But their remnants, the black holes and neutron stars, might still wander...

Strange Mathematical Term Changes Our View of Black Holes
Black holes are getting weirder by the day. When scientists first confirmed the behemoths existed back in the 1970s, we thought they were pretty simple, inert...

Physicists Glimpse Signs of 'Triangle Singularity'
Physicists sifting through old particle accelerator data have found evidence of a highly-elusive, never-before-seen process: a so-called triangle singularity. First envisioned...

Is Dark Matter Made of 'Fermi Balls'?
Dark matter — the mysterious substance that exerts gravity but doesn't interact with light — might be made of tiny black holes permeating the universe. And according to a...

Transversable Wormholes Possible Under Certain Conditions
Interested in scooting through a wormhole, the ultimate cheat-code through space and time? Perhaps you'd like to hop from star system to star system across the universe without...

What Can We Do With a Captured Asteroid?
There's gold in them thar asteroids! Literally — asteroids have more than enough gold, plus other metals, to provide a few lifetimes' worth of fortunes. But there are plenty of...

Stunning Photos, What We Know About Ganymede
NASA’s Juno probe, the supremely awesome Jupiter orbiter, recently captured some stunning images of Ganymede, the largest moon of Jupiter, during the orbiter’s 34th trip...

Universe Might Be a Three-Dimensional Donut
Imagine a universe where you could point a spaceship in one direction and eventually return to where you started. If our universe were a finite donut, then such movements would be...

Can 'Photon Spheres' Solve Black Hole Info Paradox?
Are black holes as simple as they appear, or is there more to their story? Theories that attempt to resolve the so-called black hole information paradox predict that black...

Is the Universe a Fractal? No, But Sort of Yes.
We find examples of fractals everywhere in nature. Tree branches, snowflakes, river deltas, cloud formations, and more. So it’s natural to ask the ultimate question: is the...

Can More Dimensions Explain Dark Matter?
Dark matter could be even weirder than anyone thought, say cosmologists who are suggesting this mysterious substance that accounts for more than 80% of the universe's mass could...

A Guide to Living Around a Black Hole
Black holes flood the Universe. The nearest one is a mere 1,500 lightyears away. A giant one, Sagittarius A*, sits in the center of the Milky Way about 25,000 lightyears away. While...

Weird Theory of Gravity Could Break Cause-and-Effect
Astronomers have known that galaxies across the universe are behaving badly. Some are spinning too fast, while others are just way too hot and still others glommed into super...

Is There a Pattern to the Universe?
For decades, cosmologists have wondered if the large-scale structure of the universe is a fractal — that is, if it looks the same no matter how large the scale. After...

What If Planet Nine Is a Baby Black Hole?
Some astronomers believe there is a massive planet, far beyond the orbit of Neptune, orbiting the sun — but after years of searching, scientists have not found...

A New Approach to Directly Testing Quantum Gravity
It's the ultimate dream of modern physics, to achieve what generations of scientists have failed to do for 100 years: concoct a quantum theory of gravity. But any theory will...

An Exoplanetary System Breaks all the Rules
It’s just like a normal solar system…except completely backwards. When solar systems form, both the parent star and any planets come from the same molecular cloud. As...

'Gravity Portals' Could Morph Dark Matter Into Ordinary Matter
Astrophysicists have an idea that could help to solve two mysteries: the reason for the bizarre abundance of super-high-energy radiation shooting from the center of...

We Don't Understand the Habitable Zones of Exoplanets
In the hunt for life outside the Earth, astronomers are keen to spot exoplanets in the "habitable zone," — the region around a star where liquid water can exist on a...

'Oscillon' Particles Could Have Dominated Infant Universe
A weird, super-powerful particle that's not truly a particle could have dominated the universe when it was just a second old, releasing a flood of ripples that permeated all of...

Neutrons' 'Evil Twins' May Be Crushing Stars Into Black Holes
The universe may be filled with "mirror" particles — and these otherwise-undetectable particles could be shrinking the densest stars in the universe, turning them into black...

'Bumblebee Gravity' Could Explain Universe's Expansion
Physicists have long assumed that the universe is pretty much the same in any direction, and now they've found a new way to test that hypothesis: by examining the shadow of a black...

Where Are All the Squarks and Gluinos?
Supersymmetry is the idea that the fundamental particles of nature are connected through a deep relationship. This theory predicts the existence of brand-new particles in the world's...

Are Primordial Black Holes Really Giant Gravitinos?
Astronomers don't understand the origins of the biggest black holes in the universe. These black holes appear so early in the cosmological record that we might have to invoke new...

Is There More Than One Dark Energy?
We don't know what's behind dark energy, the name we give to the current era of accelerated expansion in the universe. Many theorists favor some sort of quantum field as the driver...
