Black hole collision may have exploded with light

:ooo

Astronomers have seen what appears to the first light ever detected from a black hole merger.

When two black holes spiral around each other and ultimately collide, they send out ripples in space and time called gravitational waves. Because black holes do not give off light, these events are not expected to shine with any light waves, or electromagnetic radiation. Graduate Center, CUNY astrophysicists K. E. Saavik Ford and Barry McKernan have posited ways in which a black hole merger might explode with light. Now, for the first time, astronomers have seen evidence of one of these light-producing scenarios. Their findings are available in the current issues of Physical Review Letters.

A team consisting of scientists from The Graduate Center, CUNY; Caltech’s Zwicky Transient Facility (ZTF); Borough of Manhattan Community College (BMCC); and The American Museum of Natural History (AMNH) spotted what appears to be a flare of light from a pair of coalescing black holes. The event (called S190521g) was first identified by the National Science Foundation’s (NSF) Laser Interferometer Gravitational-wave Observatory (LIGO) and the European Virgo detector on May 21, 2019. As the black holes merged, jiggling space and time, they sent out gravitational waves. Shortly thereafter, scientists at ZTF — which is located at the Palomar Observatory near San Diego — reviewed their recordings of the same the event and spotted what may be a flare of light coming from the coalescing black holes.

“At the center of most galaxies lurks a supermassive black hole. It’s surrounded by a swarm of stars and dead stars, including black holes,” said study coauthor Ford, a professor with the Graduate Center, BMCC and AMNH. “These objects swarm like angry bees around the monstrous queen bee at the center. They can briefly find gravitational partners and pair up but usually lose their partners quickly to the mad dance. But in a supermassive black hole’s disk, the flowing gas converts the mosh pit of the swarm to a classical minuet, organizing the black holes so they can pair up,” she says.

A Human-Centric World of Work: Why It Matters, and How to Build It

Ogba Educational Clinic

Long before coronavirus appeared and shattered our pre-existing “normal,” the future of work was a widely discussed and debated topic. We’ve watched automation slowly but surely expand its capabilities and take over more jobs, and we’ve wondered what artificial intelligence will eventually be capable of.

The pandemic swiftly turned the working world on its head, putting millions of people out of a job and forcing millions more to work remotely. But essential questions remain largely unchanged: we still want to make sure we’re not replaced, we want to add value, and we want an equitable society where different types of work are valued fairly.

To address these issues—as well as how the pandemic has impacted them—this week Singularity University held a digital summit on the future of work. Forty-three speakers from multiple backgrounds, countries, and sectors of the economy shared their expertise on everything from work in developing markets to why we shouldn’t want to go back to the old normal.

Tesla Giga Berlin ‘German Speed’ Construction May Surpass Gigafactory Shanghai’s ‘China Speed’

Building a factory is, unsurprisingly, a complex and long, drawn-out process. With Giga Shanghai, however, Tesla totally upended this assumption. The company achieved unprecedented speed of construction, through an efficient planning process, flexibility, and the ability to instantly learn from mistakes.

While Giga Shanghai was built in just 11 months, Tesla’s factory in Berlin will almost certainly break that record. On August 14, Tesmanian reported on the rapid progress at the site. Yet, in just the few days since, the Giga Berlin construction team made another breakthrough.

What If Your Teacher Were AI?

We would soon have an Ai teacher @ Ogba Educational Clinic.

Watch our Discussed episode where we dive deeper into the topic with Dr. Joanna Bryson: https://bit.ly/what-if-your-teacher-were-ai

Have you ever had a teacher that was just, well, kind of boring? Maybe even a little, robotic? We’ve all been there. Let’s face it, it’s hard to learn when you’re being put to sleep. But what if we found a completely new way of learning? Could a robot be a better teacher than a human? How might education change with AI?

Indian schoolgirls discover asteroid moving toward Earth

More great news:

The 10th graders were working on a school project when they discovered the asteroid, which is slowly shifting its orbit and moving towards Earth.

Two Indian schoolgirls have discovered an asteroid which is slowly shifting its orbit and moving toward Earth.

Radhika Lakhani and Vaidehi Vekariya, both studying in 10th grade, were working on a school project when they discovered the asteroid, which they named HLV2514.

The girls, from the city of Surat in the western Indian state of Gujarat, were participating in a Space India and NASA project, which allows students to analyze images taken by a telescope positioned at the University of Hawaii.

Germany’s coronavirus response is a master class in science communication

What changed things for Germany? A handful of prominent scientists communicating regularly and openly with the public. (via CNBC)…and a leader who is a scientist.

Germany, like many other countries, had a contingent of people who fought lockdowns and argued that Covid-19 was a hoax. But it also had a handful of prominent scientists communicating regularly and openly with the public. That played a huge role in drowning out rumors and misinformation, locals tell CNBC.

“We have a great educational system and everyone has access to it,” said Dennis Traub, a tech worker in Hamburg, Germany. “So I believe that many people and the majority listened to both sides and one of those sides sounded much more reasonable.”

Germany stood out for its strong science communication. For months, its top podcast was ‘Der Coronavirus,’ which provided an update on the disease from a top virologist.

MRI scans of the brains of 130 mammals, including humans, indicate equal connectivity

Researchers at Tel Aviv University, led by Prof. Yaniv Assaf of the School of Neurobiology, Biochemistry and Biophysics and the Sagol School of Neuroscience and Prof. Yossi Yovel of the School of Zoology, the Sagol School of Neuroscience, and the Steinhardt Museum of Natural History, conducted a first-of-its-kind study designed to investigate brain connectivity in 130 mammalian species. The intriguing results, contradicting widespread conjectures, revealed that brain connectivity levels are equal in all mammals, including humans.

“We discovered that —namely the efficiency of information transfer through the —does not depend on either the size or structure of any specific ,” says Prof. Assaf. “In other words, the brains of all mammals, from tiny mice through humans to large bulls and dolphins, exhibit equal connectivity, and information travels with the same efficiency within them. We also found that the brain preserves this balance via a special compensation mechanism: when connectivity between the hemispheres is high, connectivity within each hemisphere is relatively low, and vice versa.”

Participants included researchers from the Kimron Veterinary Institute in Beit Dagan, the School of Computer Science at TAU and the Technion’s Faculty of Medicine. The paper was published in Nature Neuroscience on June 8.
