Physicists Are Backing Away From The Biggest Discovery Of The Century

Back in March, a group of physicists announced the first direct evidence of the Big Bang in a splashy press conference followed by Nobel prize forecasts and champagne. But scientists have since questioned the discovery, and a new paper suggests the signal detected was not evidence of the Big Bang but instead largely, if not entirely, from interstellar dust. Oops.


Physicists Are Making Solid Light

A team of researchers from Princeton University has started doing some very strange things with light. Instead of letting it zip by at incredibly high speed, they’re stopping it dead: freezing it into crystal.


Scientists Have Recorded The Sound Of A Single Atom

What’s the sound of one atom moving? That might sound a bit like a silly philosophical question, but actually it’s a scientific puzzle that’s now been solved.


How Long Humans Can Live In Space -- And What Happens If We Stay Too Long

How long can humans live in space? We don’t know the answer to that. But every crew that resides on the International Space Station provides us information that we use to adjust our protocols and extends that period of time.


What Would Happen If The Sun Ceased To Exist For Just One Second?

If you mean simply “is not visible” then very little, we’d have a second of darkness, not unlike an eclipse, and then we’d be back to normal. If on the other hand, you mean “ceases to exist momentarily” then you’re talking about something else entirely.


Read Richard Feynman's Best-Known Lectures For Free

Briefly: In 1964, Richard Feynman gave a series of seven, hour-long lectures at Cornell University that have gone down in history as a wonderfully accessible introduction to physics. Now, you can read them online for free.


TNT-Coated Carbon Nanotubes Could Generate Future Electricity

Light the touchpaper and stand well back, because we’re about to… make sustainable electricity? That’s the idea according to a researcher from MIT, whose vision for future power generation involves a healthy dose of TNT.


Schrödinger's Cat, Caught On Camera

While quantum mechanics is tough to get your head round, you probably know about Schrödinger’s poor old cat: left in a box, both alive and dead at the same time. Well, now there’s a picture of the ill-fated feline.


Physicists Want To Know If We're All Actually Living In A Hologram

Although it sounds entirely like something dreamed up in a smoke-filled dorm room, whether the entire universe is hologram is a very serious question — a question that gets at the heart of a fundamental problem in physics. A new experiment starting up at Fermilab just might hold the answer.


Physicists Use Lasers To Chill The World's Coldest Molecules

If you thought last winter was cold, you should stay as far away from magneto-optical trapping as possible. Yale physicists recently used this technique to cool a molecule of strontium monoflouride down to 2.5 thousandths of a degree above absolute zero. That makes them the world’s coldest molecules.
