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 […]
If dark matter exists in a large halo in our galaxy, made up of particles, then it's passing through us constantly. But how much?
Research from NASA reveals Mars’ spectacular volcanic past.
"Our mission is to completely replace the use of animals as a food technology by 2035," said Patrick O. Brown at the 2020 Web Summit.
Artifacts uncovered in southeast Asia offer clues on early complex human cultures.
The Universe, according to our best understanding, just doesn’t add up. The Universe, according to our best understanding, just doesn’t add up. Wherever we look — from tiny subatomic scales all the way […]
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 […]
When Saint Ambrose of Milan was venerated, his life became public property, its meaning expanding with the unique interpretations of each new generation.
As particles travel through the Universe, there's a speed limit to how fast they're allowed to go. No, not the speed of light: below it.
The double-slit experiment, all these years later, still holds the key mystery at the heart of quantum physics. When we divide up matter into the smallest possible chunks that it’s made […]
The neutrino is the most ghostly, rarely-interacting particle in all the Standard Model. How well can we truly make "beams" out of them?
Fermilab's TeVatron just released the best mass measurement of the W-boson, ever. Here's what doesn't add up.
Smashing things together at unprecedented energies sounds dangerous. But it's nothing the Universe hasn't already seen, and survived.
The highest-energy particles of all come from space, not human-made colliders. When it comes to the most energetic particle collisions of all, you might think that the Large Hadron Collider […]
Could we finally detect the elusive Unruh effect?
A thought experiment from 1867 leads scientists to design a groundbreaking information engine.
With two different black hole event horizons now directly imaged, we can see that they are, in fact, rings, not disks. But why?
Particle physics needs a new collider to supersede the Large Hadron Collider. Muons, not electrons or protons, might hold the key.
With advanced laser technology and an appropriate sail, we could accelerate objects to ~20% the speed of light. But would they survive?
Everything is made of matter, not antimatter, including black holes. If antimatter black holes existed, what would they do?
The way to understand the earliest moments of creation is to recreate those conditions and study them. Why would we stop now?
The laws of physics state that you can't create or destroy matter without also creating or destroying an equal amount of antimatter. So how are we here?
Over time, the Universe becomes less dominated by dark matter and more dominated by dark energy. Is one transforming into the other?
Our remarkable olfactory senses are modeled in a new research chip.
The idea of gravitational redshift crossed Einstein's mind years before General Relativity was complete. Here's why it had to be there.
