Physicist Claim That They've Figured Out How To See Into A Blackhole.

Physicists have presented a new method to predict what really lies inside the event horizon of a black hole, and it can give us a more precise information about their mysterious internal structures. Studying black holes is mainly like doing science backwards. You are familiar with the scientific method, observe, analyze, experiment and hypothesize. But when it comes to black holes, we initiate with the hypotheses and mathematics, and then try to work out how to detect what we think is there.

But there’s seems to be a one big problem with the current method, as a group of astronomers from Johns Hopkins and Towson University point out - physicists have been building their opinion of the internal structure of a black hole founded on how certain mathematical coordinates fit together.

Liable on which coordinates you select, and how they’re observed from your position as an observer, you’ll possibly get very diverse outcomes from someone who picks a different set of coordinates from another perspective.

The best example for this is, our maps and atlases that we have made when it comes to our view of our own planet, because we’ve been signifying certain landmasses subjectively, rather than relatively.

Astronomers argue that

"Any such coordinate choice necessarily results in a distorted view, just as the choice of projection distorts a map of the Earth. The truest way to depict the properties of a black hole is through quantities that are coordinate-invariant."

The team, led by physicist Kielan Wilcomb from Towson University, recommend that in order to find out what’s inside a black hole, you must concentrate entirely on mathematical quantities called invariants, which have the similar value for any choice of coordinates.

At the 228th conference of the American Astronomical Society in San Diego just this week, the group of astronomers stated that there are 17 such quantities linked to the curvature of space-time that can be used to observer and study black hole interiors. Because of certain mathematical relationships among them, they say only five are actually independent.

The team’s research has been published on the pre-press website arXiv.org ahead of peer-review, so other physicists can use these five invariants to try to build the inside of a hypothetical black hole. According to Wilcomb and co. say they tried it out themselves, they actually saw something really awesome

"We compute and plot all the independent curvature invariants of rotating, charged black holes for the first time, revealing a landscape that is much more beautiful and complex than usually thought."

Now what we need to do now is to just figure out if we can get to another universe through a black hole, so we can all plot our parallel universe vacations.

A Giant Galaxy orbiting Our Own Out of Nowhere !

Astronomers scanning the skies just got a huge surprise. They discovered a gigantic galaxy orbiting our own, where none had been seen before. It just came out of nowhere. So, just how did the recently-discovered Crater 2 succeed to pull off this feat, like a deer jumping out from the interstellar bushes to suddenly shock us? Even though the appearance may seem sudden, the Crater 2 has been there all along. We just never saw it.

Now that astronomer know it’s there, though, there are a few other crushing facts that astronomers discovered. First of all, we can’t blame the galaxy’s size for its relative insignificance. Crater 2 is so massive that researchers have already identified it as the fourth largest galaxy orbiting our own. We can’t even blame its distance, either. Crater 2's orbit around the Milky Way puts it just precisely in our neighborhood.

That being said, the question arises, how did we still not know it was there? A new research paper published in Monthly Notices of the Royal Astronomical  Society from astronomers at the University of Cambridge has an answer for us. It turns out that, regardless of being huge and close, Crater 2 is also a pretty dark galaxy. Actually, it’s one of the faintest galaxies ever detected in the cosmos. That, along with some much perkier neighbors, let the galaxy that astronomers have nicknamed “the feeble giant” remain hidden from our eyes until now.

Now that we have observed Crater 2, nevertheless, the discovery yields some questions about what else could be out there that we are still missing. Astronomers are already talking about starting a hunt for similarly large, dark galaxies near us. It’s a good thing that there’s still so much about cosmos that we still don’t know.

Lenovo unveils bendable screens and other novel tech

   

Lenovo is adding experimental technologies to its smartphones in a bid to grow its business, trying to overcome declining PC shipments and a competitive phone market.

At Lenovo Tech World in San Francisco, the company showed off a prototype bendable phone that can articulate around your wrist, as well as a tablet that can be folded in half to use like a phone.

"Over the past two years Lenovo has been transforming, making major acquisitions in mobile and infrastructure to expand beyond our core PC business," said Yuanqing Yang, the company's chairman and chief executive officer. "I was told we'd better launch something pretty exciting."

While neither of the bendable devices is likely to make it to market anytime soon, the Beijing-based company also announced a phone that uses a Google sensory technology named Tango, and announced two new Motorola handsets that can be augmented with additional equipment via 16 "magic dots" in their backs.

The Tango phone, called the Phab 2 Pro, will roll out from September this year and is capable of mapping the 3D space around you in real time. This allows for new kinds of apps that, for example, display 3D computer images correctly in real space or allow you to see how new furniture would look in your room. 

With the Phab2 Pro, Lenovo will be the first company to field AR technology on smartphones without the need of a headset, separate device or attachment to a powerful computer.

"Lenovo is creating a new kind of AR experience that is more portable, more practical, and will be even more popular," Yang said.

Meanwhile the Motorola handsets, like LG's G5 and Google's Project Ara prototype, allow you to snap on addition modules to define the features of your phone. The MotoZ and MotoZ Force can be upgraded with additional equipment via what the company is calling Moto Mods. This lets people easily add battery power, speakers, projectors and other hardware capabilities to its phones by fastening the equipment with 16 "magic dots" — or high-powered magnets — to the phone's back.

"Now your phone is not just your phone," Yang said. With Moto Mods, the phone "can transform into whatever you wanted it to be or needed to be," he said.

Lenovo is looking to phones for growth to offset a struggling PC market. Lenovo was the largest single vendor of PC shipments in the first quarter of 2016, according to IDC, but shipments declined 8.5 per cent on a year earlier. The company acquired the Motorola smartphone business for $US2.8 billion in 2014 to help it hedge against this weakness, but turning those phones into major sales has proven to be a challenge.

NASA just confirmed that earth has a mini moon !

One is the loneliest number, especially when you are a single moon circling the planet full of humans. But let’s not lose hope here because NASA just announced that there might be a second moon come to keep you company. This newly discovered moon is smaller than our moon and goes around the Earth astonishingly irregularly, but still, two is quite better than one. This second “moon,” is actually an asteroid called 2016 HO3 and it is currently locked into “a little dance” with Earth. It's being called as "Quasi-Moon".

 This new moon has been dancing around for over a century now. Its orbit is extremely elliptical, affecting it to go a wee bit off tangent—between 38 and 100 times the distance of Earth’s primary moon—and bob up and down across Earth’s orbital plane. This new moon is tilted by about 8° and it orbits the Sun for 365.93 days, which is a little longer than Earth’s 365.24 day-long year. 

NASA said: 

“Since 2016 HO3 loops around our planet, but never ventures very far away as we both go around the sun, we refer to it as a quasi-satellite of Earth”

Since it’s tilted and has an elliptical orbit, sometimes it is

quite closer to the Sun and moving a little faster than Earth. Other times, it is a little bit farther out and moving a bit more slowly, however it never gets any closer than about 14 million kilometers from Planet Earth or farther than about 40 million kilometers.

According to NASA, it’s larger than 36.5 meters across, but no more than 91 meters wide, and will circle earth for many more centuries to come.

2016 HO3 was first discovered by astronomers in April 27 with the Pan-STARRS 1 asteroid survey telescope located in Haleakala, Hawaii.
