Physics gets strange at the atomic scale. Scientists are utilizing quantum analog simulators – laboratory experiments that involve cooling numerous atoms to low temperatures and examining them using precisely calibrated lasers and magnets – to uncover, harness, and control these unusual quantum effects.

Scientists hope that any new understanding gained from quantum simulators will provide blueprints for designing new exotic materials, smarter and more efficient electronics, and practical quantum computers. But in order to reap the insights from quantum simulators, scientists first have to trust them.

That is, they have to be sure that their quantum device has “high fidelity” and accurately reflects quantum behavior. For instance, if a system of atoms is easily influenced by external noise, researchers could assume a quantum effect where there is none. But there has been no reliable way to characterize the fidelity of quantum analog simulators, until now.

Explore what would happen if humans were suddenly eradicated from the world, and the Earth was left to heal itself. From the safety of nuclear power plants to the fate of pets, livestock, and wild animals, this video takes a detailed look at the environmental and societal impacts of such a scenario. Discover how air quality and greenhouse gas emissions would change and the Earth’s temperature would slowly return to its pre-industrial levels.

A more frightening implication of the fermi paradox.


The berserker hypothesis, also known as the deadly probes scenario, is the idea that humans have not yet detected intelligent alien life in the universe because it has been systematically destroyed by a series of lethal Von Neumann probes.[1][2] The hypothesis is named after the Berserker series of novels (1963−2005) written by Fred Saberhagen.[1]

The hypothesis has no single known proposer, and instead is thought to have emerged over time in response to the Hart–Tipler conjecture,[3] or the idea that an absence of detectable Von Neumann probes is contrapositive evidence that no intelligent life exists outside of the Sun’s Solar System. According to the berserker hypothesis, an absence of such probes is not evidence of life’s absence, since interstellar probes could “go berserk” and destroy other civilizations, before self-destructing.

In his 1983 paper “The Great Silence”, astronomer David Brin summarized the frightening implications of the berserker hypothesis: it is entirely compatible with all the facts and logic of the Fermi paradox, but would mean that there exists no intelligent life left to be discovered. In the worst-case scenario, humanity has already alerted others to its existence, and is next in line to be destroyed.[4].

Saudi Arabia introduced its first-ever robot that can communicate in the Arabic dialect, perform popular local dances, and respond to questions at a conference in Riyadh on Tuesday. The event was held at LEAP23, the techno-conference, and the robot was documented by the state news agency SPA.

The interactive machine boasts a built-in camera that uses artificial intelligence to recognize when people are standing in front of it. It can then begin a conversation when a visitor addresses it with the sentence “Hello Sara.”

Sara has the ability to recognize different dialects from within the Kingdom. She can also analyze sentences and comprehend their content.

The architecture of the new building is meant to convey the “timeless human need for connection to human and plant-life alike.”

Beijing-based MAD architects announced on Instagram on Tuesday that they won the contract to build the first large-scale air transportation junction for the new terminal of Changchun airport. The firm will now aim to create a green and sustainable structure that can accommodate all passenger needs.

The new site consists of 177.6 hectares with a building area of nearly 270,000 square meters and is located in Changchun, a city well-known as the international, regional hub in Northeast Asia with a population of 23 million.

These tiny black holes lose mass faster than their massive counterparts, emitting Hawking radiation until they finally evaporate.

One of the most intriguing predictions of Einstein’s general theory of relativity.

When a sufficiently massive star runs out of fuel, it explodes, and the remaining core collapses, leading to the formation of a stellar black hole (ranging from 3 to 100 solar masses).

Supermassive black holes also exist in the center of most galaxies.


So far, astronomers have captured images of two supermassive black holes: one in the center of the galaxy M87 and the most recent in our Milky Way (Sagittarius A*).

But it’s believed that another kind of black hole exists – the primordial or primitive black hole (PBHs). These have a different origin to other black holes, having formed in the early universe through the gravitational collapse of extremely dense regions.

Separating the Tesla CEO and first place within the wealth standings is simply $3 billion, claims a media report.

Despite losing 200 billion in 2022, Elon Musk is on a recovery, inching closer than ever to reclaim the throne of the world’s richest person.

Elon Musk may soon “reclaim the title of world’s richest person,” claimed a media report on Saturday. “Separating the Tesla CEO and first place within the wealth standings is simply $3 billion.

The 51-year-old tech billionaire climbed back to the second spot and is worth 188.6 billion at present, according to the most recent numbers posted on Forbes world’s richest person list on Saturday.

The ship design has ‘solar wings.’

Designer Jozeph Forakis has introduced the world’s first 3D-printed super yacht concept, and it’s called Pegasus. The concept is 88 meters long and comes complete with reflective ‘Solar Wings,’ allowing it to have zero emissions and an infinite range.

The idea for the futuristic yacht was conceived on a beach in Koufonissi island, Greece. Forakis claimed to be “inspired to create a yacht as close to the sea and nature as possible, made of clouds floating above the waterline, becoming virtually invisible,” according to the designer’s page.

Running ChatGPT costs millions of dollars a day, which is why OpenAI, the company behind the viral natural-language processing artificial intelligence has started ChatGPT Plus, a $20/month subscription plan. But our brains are a million times more efficient than the GPUs, CPUs, and memory that make up ChatGPT’s cloud hardware. And neuromorphic computing researchers are working hard to make the miracles that big server farms in the clouds can do today much simpler and cheaper, bringing them down to the small devices in our hands, our homes, our hospitals, and our workplaces.

One of the keys: modeling computing hardware after the computing wetware in human brains.


“Inference costs far exceed training costs when deploying a model at any reasonable scale,” say Dylan Patel and Afzal Ahmad in SemiAnalysis. “In fact, the costs to inference ChatGPT exceed the training costs on a weekly basis. If ChatGPT-like LLMs are deployed into search, that represents a direct transfer of $30 billion of Google’s profit into the hands of the picks and shovels of the computing industry.”

If you run the numbers like they have, the implications are staggering.

“Deploying current ChatGPT into every search done by Google would require 512,820 A100 HGX servers with a total of 4,102,568 A100 GPUs,” they write. “The total cost of these servers and networking exceeds $100 billion of Capex alone, of which Nvidia would receive a large portion.”
