Physics

New research shows what light was like when the universe was first born.

Weak nuclear force is stronger than gravity, but weaker than, you know, strong nuclear force.

The study solves a heated debate among physicists.

A super powerful laser would be used to reverse the process by which we convert heat and light into matter to create nuclear weapons.

Christa McAuliffe was planning to film lessons aboard the Challenger for classrooms all over the country to use.

Einstein described his friend's personality, calling him "goodhearted" but also someone with "a rather sterile, rabbinical mind."

"Acoustic researchers had been frustrated by the size limit for years, so it's satisfying to find a way to overcome it."

"We can make structures that nobody's ever even conceived of before; this is a true man-over-nature event."

The European Union and the United Kingdom are committing the equivalent of hundreds of millions of dollars each to quantum tech.

If you pull it, it moves away. If you push it, it accelerates toward you.

Supercooled water droplets can exist naturally, but physicists still don't know just how cold liquid water can get.

It's a big step forward in RHIC's ongoing quest to solve the mystery of atomic spin.

Even if we can't get to the fourth dimension, we may be able to make use of it.

Standard radio signals often fail because they can't penetrate complex materials like water or rock. Quantum radio can.

It changes shape in response to the temperature or chemical makeup of its environment, making it something between a chameleon and a Transformer.

Klystrons are powerful generators for creating the electromagnetic fields that accelerate particles within atom smashers.

The temperature the physicists achieved corresponds to -459.665 degrees Fahrenheit.

It's possible to design larger (and cruder) snowflakes. But perfect, single crystals are a different story.

Thank Newton for our understanding of rainbows and the motion of soccer balls.

Forget everything you thought you knew about Schrödinger's cat.

Physicists stumbled upon a new theoretical model in which electrons suddenly act the way a ray of light does.

How physicists finally showed us time can move backwards.

For a century, scientists have relied on a fundamental assumption about the brain's neurons. New research shows it's wrong.

A plasma blade could vaporize your opponent—and yourself.

New research into how life on Earth began offers further evidence that extraterrestrial origins may be plausible.

The 700-foot tall, 300-mile-long wall has been protecting the Seven Kingdoms for thousands of years. Would it hold up on Earth?

While scientists had suspected plasma sheets were unstable, no one had ever managed to characterize that instability until now.

Physicists can't explain the mysterious force.

Mathematicians have discovered the answer.

Excitonium is such uncharted territory that scientists don't yet know what its properties are.
