Hawking: 'Black Holes Ain't as Black as Painted'

Physicist claims to have solved the information paradox

(Newser) - "If you feel you are in a black hole, don't give up. There's a way out." So says Stephen Hawking in claiming to have resolved the so-called information paradox—the seemingly irreconcilable problem of two well-accepted tenets involving black holes. Quantum mechanics dictates that the information... More »

Hawking's New Theory: 'There Are No Black Holes'

He addresses conflicting theories of physics

(Newser) - Stephen Hawking helped develop current theories on black holes—but now, he's saying there aren't any. New Scientist explains his thinking, focusing on what's known in physics as the "firewall paradox," which deals with a black hole's event horizon. That's an "invisible... More »

Welcome to Physics, Class; Now, I Strip

Columbia professor's bizarre stunt gets his students' attention

(Newser) - Turns out, it is possible for a video of a quantum mechanics professor welcoming his freshman students to go viral. But as the Columbia Spectator explains, it requires said professor to strip to his skivvies to the backbeat of a Lil Wayne song while a montage of images of 9/11,... More »

New 'Quantum Teleportation' Record Wows Scientists

Photons send quantum information across 89 miles

(Newser) - Quantum teleportation won't beam you up to the Starship Enterprise—at least not yet. But scientists are able to tweak "entangled" photons at greater distances than ever before, Scientific American reports. In case you haven't been freaked out yet: Scientists can separate two photons by dozens of... More »

God Not Necessary for Big Bang: Scientists

But that doesn't mean there is no God

(Newser) - The Big Bang could have brought the universe into existence whether or not God exists, researchers said at the recent SETICon 2 conference. "The Big Bang could've occurred as a result of just the laws of physics being there," said one astrophysicist. "With the laws of... More »

We Just Moved Closer to Teleportation

How 'you' can be in 2 places at once

(Newser) - It's a tongue-twister, and it can get messy, but "quantum entanglement" may one day make it possible to teleport people across the galaxy faster than the speed of light. And it won't happen like Star Trek, with people beaming from one place to another. Rather, it involves quantum mechanics... More »

Scientists Teleport Data on Tiny Scale

Send information between atoms a meter apart

(Newser) - It’s not quite worthy of the Starship Enterprise, but Maryland scientists have managed to teleport data on an atomic scale, LiveScience reports. The researchers transmitted information between atoms a meter apart without the data actually crossing that space—a development that could help create speedy quantum computers and highly... More »

Move Over, Heisenberg: Electron Caught on Film

Elusive negative charge stars in Swedish researchers' breakthrough video

(Newser) - Electrons are tiny, fast, and, until recently, impossible to capture on film. But a short, super-slow-mo video offers the first direct look at the wily subatomic particle. Coaxing the reclusive electron into the limelight took major maneuvering by Swedish scientists, LiveScience reports. The paparazzi of physicists caught the negative particle... More »
