It should be just as sticky (or non-sticky) as normal matter. Here’s how we know. Not only here on Earth, but everywhere in the Universe that we look, we find structures […]

Demanding appropriate levels of skepticism and scrutiny isn’t cruelty, but rather demonstrates scientific integrity and intellectual honesty. Every few months, a novel headline will fly across the world, claiming to […]
There were at least four major climate catastrophes that reshaped global religion. It could be happening again.
As it turns out, people who can afford to fly all the time use more energy than anybody else.
Even physicists sometimes fall for these. For centuries, the laws of physics seemed completely deterministic. If you knew where every particle was, how fast it was moving, and what the forces […]
Smallpox was nothing new in 1721.
Hidden variables aren’t ruled out, but they can’t get rid of quantum weirdness. Ever since the discovery of the bizarre behavior of quantum systems, we’ve been forced to reckon with […]
So far, 30 student teams have entered the Indy Autonomous Challenge, scheduled for October 2021.
And can we devise an experiment to tell, even when we aren’t looking? One of the most bizarre aspects of quantum physics is that the fundamental entities that make up the […]
Hawking radiation should really be happening, but black holes are farther from decaying than ever before. Black holes are, in many ways, the most extreme objects that will ever exist in […]
How does one supernova get so bright, so energetic, and so massive? It’s a spectacular mystery to solve. On February 22, 2016, one of humanity’s automated sky-scanning telescopes — the Pan-STARRS Survey for […]
It happened 13.8 billion years ago, so why hasn’t the radiation all passed over us by now? For the past 13.8 billion years, our Universe has been expanding, cooling, and gravitating. […]
Esoteric evidence points to a ritual performed by Queen Elizabeth’s court magician John Dee.
Argentina’s black market for cash is embracing crypto — but it’s not what crypto proponents expected.
Anastasia lives alone in perfect harmony with nature – or so the story goes – and nature serves her devotedly.
As time goes on, every galaxy beyond our local group will speed away from us faster and faster. And yet, more will keep appearing. The farther away a galaxy is […]
The drive would provide enough thrust for a spacecraft to travel near the speed of light using only electricity, says physicist Jim Woodward.
An ancient Martian meteorite carries with it some compelling implications.
50% of stars are in Sun-like ‘singlet’ systems. The planetary nebulae we see just don’t line up. Around 7 billion years from now, our Sun’s life will end. As the Sun […]
At a fundamental level, nobody knows whether gravity is truly quantum in nature. A novel experiment strongly hints that it is.
Princeton scientists find a new way to control nuclear fusion reactions.
Nothing in the Universe can travel faster than the speed of light. So how does space itself do it? One of the fundamental rules we all learn in physics — set forth by […]
A generation ago, NASA launched their great observatories to explore the Universe. It’s time for round 2. Throughout the history of astronomy, every advance we’ve ever made has come about because […]
A new study found similarities between the human brain and the cosmic network of galaxies.
Binary pulsars are doing what no other measurement has done: measure our galactic acceleration directly. Even though the majority of the matter that makes up our Universe may be completely […]
Construction is nearly complete for a camera that will take 3,200-megapixel panoramas of the southern night sky.
If we are wreaking havoc on ourselves and the world, it is because we have become mesmerized by a mechanistic, reductionist way of thinking.
July 4th and New Years Eve are the most dangerous times for a hail of falling bullets from ‘celebratory gunfire.’ “What goes up, must come down,” is an old saying […]
Deniers will never stop misleading others. Here’s the truth. Every so often, advocates of a fringe theory — one that doesn’t fit the evidence as well as the mainstream theory — do what they can […]
Using permanent magnets may help to make nuclear fusion reactors simpler and more affordable.
