Can You Spare A Zeptosecond? Scientists Have Just Measured The Shortest Unit Of Time Ever 

This image shows a photon removing an electron from a helium atom, with the remaining electron most likely near the bright nucleus. 

A millisecond is a thousandth of a second, and a nanosecond is a billionth of a second, but there’s another measurement of time that makes both of them look slow.

Scientists have for the first time been able to measure something in a zeptosecond, or a trillionth of a billionth of a second.

Laser physicists in Munich fired an extreme ultraviolet light pulse onto a helium atom to excite the electrons, causing one to break free ― a process called photoemission. At the same time, they shot an infrared laser pulse to detect the electron as it left the atom.

That’s when it happened.

“Depending on the exact electromagnetic field of this pulse at the time of detection, the electron was accelerated or decelerated,” the Technical University of Munich stated in a news release. “Through this change in speed, the physicists were able to measure photoemission with zeptosecond precision.”

The experiments also allowed scientists to see how energy from the photon was distributed between the two electrons in a helium atom in the moments before one of the electrons jumped out. That snapshot of a tiny moment in time will allow scientists a greater understanding of the quantum behavior of atoms.

Many things are rooted in the interactions of individual electrons, but we handle them as a collective thing,” laser physicist Martin Schultze of Ludwig Maximilian University of Munich, who led the experiments at the Max Planck Institute of Quantum Optics, told New Scientist. “If you really want to develop a microscopic understanding of atoms, on the most basic level, you need to understand how electrons deal with each other.”

Taylor Swift sealed photo hits the Internet

Taylor Swift’s Photo Of Alleged Groping Incident Revealed


The photo possibly showing Taylor Swift being grabbed inappropriately by a Denver DJ has been leaked online, despite a judge’s order that it remained sealed, according to Fox News.

Swift is being sued by, and has countersued, David Mueller, whom Swift says touched her during a 2013 concert meet-and-greet. The singer asked the judge to seal the photo.

TMZ published the photo, in which Swift stands between Mueller and another woman. Swift’s arms are around the person on either side of her, while Mueller’s right hand appears to be behind her lower back.

The singer says that’s when Mueller grabbed her rear end.

“Right as the moment came for us to pose for the photo, he took his hand and put it up my dress and grabbed onto my ass cheek and no matter how much I scooted over it was still there,” Swift said, in a deposition. “It was completely intentional, I’ve never been so sure of anything in my life.”

Swift said she felt “violated in a way I had never experienced before.”

Mueller denies the accusations.

Project Blue on Kickstarter may photograph the first Earth-like planet 

The first telescope to photograph a “pale blue dot” of another Earth in a distant solar system may not be funded by NASA, the European Space Agency, or some other government agency.

It might come from Kickstarter.

Dubbed Project Blue, the effort isn’t run by hucksters out to peddle unrealistic technologies. A consortium of professional scientists and engineers, some of whom work at NASA, is running the show as a nonprofit called Mission Centaur.

“We’re looking for a place that could support life,” Supriya Chakrabarti, an optical and space scientist at the University of Massachusetts Lowell who’s part of Project Blue, told Business Insider.

Mission Centaur hopes its six-week panhandle on Kickstarter, which starts November 15, nets them at least $1 million — enough cash to pick up the work that a group of the researchers started at NASA but couldn’t get more funding to support.

It says the money will go toward further design and research of the project.

The group ultimately expects the mission to cost between $25 million and $50 million to get into orbit around Earth within the next four to six years. That price tag includes sharing a ride on a rocket like SpaceX’s Falcon 9, and it’s nothing compared with the billions NASA has spent on space observatories.

Once in orbit, an epic two-year stare-down would begin.

Chakrabarti said he’s confident that crowdfunding the first stage of Project Blue will work out, buying time to attract a big following — and bigger funders later on.

“After ghosts and dinosaurs, space comes a close third, in terms of people’s interest,” he said.

Shooting in the dark

Project Blue’s target is Alpha Centauri, a system that contains two of the closest stars to our own solar system at just 4.4 light-years away.

One of the stars, called Alpha Centauri A, is even sunlike.

However, nobody actually knows if a blue marble like Earth — a world with liquid-water oceans, a cozy atmosphere, and other conditions necessary for life — might lurk in the double-star system. Not even the Hubble Space Telescope, the planet-hunting Kepler space telescope or other advanced observatories could tell an astronomer.

So it’s a bit of a gamble to make even a small telescope that’s purpose-built to stare down one star system.

But Chakrabarti and the other Mission Centaur scientists think it’s a good bet. They cite the most recent planet-hunting data from Kepler that pegs the odds of a rocky planet orbiting a star’s “habitable zone,” or close enough to create liquid water, near 85%.

“Roughly one out of every two stars has a potentially habitable planet,” Ruslan Belikov, an astrophysicist at NASA Ames Research Center, said in “The Search for Earth Proxima” — a short documentary about the project. “The number of potentially habitable planets in our galaxy alone is greater than the number of people alive on Earth.”

According to Lee Billings at Scientific American, Belikov and another scientist in 2014 pitched NASA a telescope similar to Project Blue, “but the agency passed over the speculative, narrowly focused project.”

That’s not too much of a surprise, since NASA likes its space telescopes more like Swiss Army knives and able to view multiple targets with ease. The equipment and techniques also weren’t quite there at the time — hurdles that Mission Centaur no longer foresees.

“The technology required to do this is only very recent. It hasn’t been ready until now,” said Brett Marty, the documentary’s filmmaker and the executive director of Mission Centaur.

How to photograph an ‘Earth Proxima’

At roughly the size of a modest washing machine, Project Blue would be a pretty dinky space telescope if built — certainly compared with the school-bus-size Hubble.

But it doesn’t need to be large. It’s focused on only one part of the sky and needs minimal electronics — whereas Hubble needs large gyroscopes and multiple cameras to move and take aim at different objects in space.

Project Blue’s ultimate task is resolving any very dim objects next to ones 1 billion to 10 billion times brighter.

“Imagine there’s a marble next to a lighthouse in Cape Cod,” Chakrabarti said. “Now try to image that marble from San Francisco. That is what we’re dealing with.”

He said that “three key technologies matured enough that we can tell people with a straight face that we’re now actually ready to go and do this thing.”

One is a miniaturized version of a coronagraph, a complex instrument that can blocks each star’s blinding light and can reveal planets hiding in the glare.

“It’s kind of like playing tennis and the sun is in your eyes,” Marty said. “When you put your hand up to block it, you can see the ball coming. Here we’re suppressing both stars at once” and catching the balls.

Keeping the precision while shrinking what’s normally a very large instrument wasn’t easy, they said.

The next challenge was that “it’s near impossible to make a perfect mirror,” or at least a large one, Chakrabarti said.

The solution? A “deformable” mirror, which is a computer-chip-like array of about 1,000 ultra-tiny (and very perfect) mirrors that can be programmed to move with microscopic precision thousands of times a second, helping cancel out any optical imperfections in the telescope.

The third and final technical hurdle to making Project Blue possible was image stabilization.

“A crisp image is what is needed because the planet would be so close to the star,” Chakrabarti said. “We have built such a system and proven it works to the level Hubble can point.”

Marty said it’s similar to the gyros in consumer cameras that stabilize an image — though far more exacting.

“This is really the reason we’re able to do this mission at such a low cost,” he said.

To prove the stabilizers worked well enough to keep Project Blue gazing endlessly at Alpha Centauri, Chakrabarti’s team launched experimental prototypes toward the edge of space, some 60 miles up. For the few minutes they floated in the thin air before falling back to Earth, they perfectly stabilized the experimental rig.

If all goes according to plan, Project Blue will take hundreds or even thousands of pictures of the star system in three colors (including blue), merge the giant pile of images, and lift a pale blue dot out from the noise of pixels.

“We have to take care of every single possible event that could contribute to this noise,” Chakrabarti said. “This is why we’ve decided we need at least two years of measurement to convince ourselves we’re seeing a true, Earth-like planet.”

What if it works?

It’s important to note this isn’t the closest star system, which we heard a lot about earlier this year: a red dwarf star called Proxima Centauri.

Although a dogged team of astronomers strongly believes a rocky, Earth-size planet called Proxima b is circling that star in its habitable zone, Chakrabarti and Marty said it’s not a great target for their ragtag operation.

At about 4 million miles away from its star, Marty said, “There’s a lot of radiation. It’s also a tricky target and hard to resolve, and it might not be anything like our planet.”

An observatory like the behemoth James Webb Space Telescope might be the first to study that world, though it wouldn’t be a “pale blue dot” photo — more like a fuzzy heat signature that could indicate “this is an incinerated hellhole” or “a useful atmosphere and potentially water lurk here.”

Project Blue, of course, actually intends to return images of a habitable planets, like this:

If Project Blue works, Mission Centaur said it could launch a new era of planet-hunting telescopes.

Also, Russian billionaire Yuri Milner and his Breakthrough Starshot project — an effort to laser-propel tiny spacecraft to the Alpha Centauri or Proxima Centauri systems — would have a solid and intriguing target.

But even if that pie-in-the-sky idea falls down and all we’re left with is a crummy image of a pale blue dot, it would still be Earth-shattering.

“Finding an Earth Proxima would be a transformative event in the history of mankind,” Bill Diamond, president and CEO of the SETI Institute, said in the documentary. “I would love to think that is something that helps bring us together. It’s a very unifying thing.”

And in divisive times like these, unity is something the human race could use a lot more of.

You’ll Need An Appointment To Get Nike’s New Self-Lacing Sneakers 

Ladies and gentlemen, the future is finally back.

Nike first announced its upcoming self-lacing sneaker in March, and Wired reported on the shoes’ jaw-dropping capabilities in the video above in October. But now we have even more information on the seemingly magical HyperAdapt 1.0, which will be available for purchase Dec. 1.

Before you Marty McFly to your local Nike store for a pair of your own, be forewarned: You won’t be able to get your hands on a pair without a hefty wad of cash ― $720 ― and an appointment.

The super cool sneaks contain a sensor that automatically starts the self-lacing mechanism when you insert your feet, plus two buttons to loosen or tighten the laces to the wearer’s desire. The lacing system works off a rechargeable battery and the shoes boast an LED light to display how much battery is left.

As Wired explains in the video above, the sneakers are said to be ideal in an athletic event like a marathon or basketball game, when every second spent tying and re-tying shoes is crucial. Or, you know, when you want to impress your friends.

It could be yours, for a price. 

In a statement released last week, Nike revealed that the shoe will initially be available at two locations in New York City’s Soho neighborhood starting Dec. 1: the Nike store and the Nike+ Clubhouse.

“Consumers can learn about and trial the product at a retail price of $720,” the statement reads.

Those wishing to book an appointment can visit the Nike website or the Nike+ app. A spokeswoman for the brand told The Huffington Post that more information will become available later next week, and all new developments will be posted to the Nike news site. The brand also stated that “a small group of NIKE+ app users” will have early access to the shoes on Nov. 28, before a wider release in two colorways later in December.

HyperAdapt 1.0 will be available in the U.S. at select Nike retail locations. Appointments to experience & purchase begin 11.28.16.

At $720, we’ll stick to tying our sneakers the old fashioned way for now. But they arepretty darn epic.
