A massive burst of gamma rays produced by the explosion of a star almost two billion light-years away was so powerful that it changed Earth’s atmosphere, according to scientists.
The brightest gamma-ray burst ever seen and detected impacted Earth’s atmosphere. It came from a supernova and may reveal why Earth has had mass extinctions in its past.
Nvidia is on a tear.
But “there are no companies that are assured survival,” Huang warned Thursday at the Harvard Business Review’s Future of Business event.
Nvidia in its 30-year history has faced several existential threats, which helps explain why Huang recently told the Acquired podcast that “nobody in their right mind” would start a company. For example, it almost went bankrupt in 1995 after its first chip, the NV1, failed to attract customers. It had to lay off half its employees before the success of its third chip, the RIVA 128, saved it a few years later.
“We have the benefit of building the company from the ground up and having not-exaggerated circumstances of nearly going out of business a handful of times,” Huang said this week, as Observer reported. “We don’t have to pretend the company is always in peril. The company is always in peril, and we feel it.”
How they can prevent life in other planetary systems. Giant gas planets can be agents of chaos, ensuring nothing lives on their Earth-like neighbors around other stars. New studies show, in some planetary systems, the giants tend to kick smaller planets out of orbit and wreak havoc on their climates.
Jupiter, by far the biggest planet in our solar system, plays an important protective role. Its enormous gravitational field deflects comets and asteroids that might otherwise hit Earth, helping create a stable environment for life. However, giant planets elsewhere in the universe do not necessarily protect life on their smaller, rocky planet neighbors.
A new Astronomical Journal paper details how the pull of massive planets in a nearby star system are likely to toss their Earth-like neighbors out of the “habitable zone.” This zone is defined as the range of distances from a star that are warm enough for liquid water to exist on a planet’s surface, making life possible.
North Korean leader Kim Jong Un is “seriously preparing” for war as it builds its nuclear weapons arsenal, according to an expert on Korean history.
After decades of international pressure attempting to stop its development of nuclear weapons, North Korea announced during the administration of former President George W. Bush that it was conducting nuclear tests and had weapons. The country now has an arsenal that includes an estimated 35 to 63 warheads, according to the Institute for Science and International Security.
In an interview published by The Financial Times on Thursday, Kookmin University history professor Andrei Lankov said that Kim had been emboldened to build the nuclear arsenal due to Western leaders failing to take advantage of earlier opportunities to pressure the regime, wrongly believing that the nuclear program was not “a realistic threat.”
Although essentially the United Nations are now making nuclear weapons illegal with new treaties like nuclear disarmament. Russia currently has taken another route for globalization and possibly nuclear escalation. As currently the doomsday clock seems closer to midnight which could mean the end of the world scenarios due to Russias escalation and the possibility of all out nuclear war globally and then nuclear annihilation of the planet. Even with current wars are actually seemingly always going on but this global escalation of nuclear war is a zero sum game as no one would be the winner due to radiation levels circulating the planet. I do think that the us and china are in a treaty but so far Russia is still escalating which now holds the world now ransom.
This is a summary of Policy Brief 139 which is available with full references on the Toda Peace Institute’s website.
In January 2021, a global treaty came into force outlawing the bomb. The Treaty on the Prohibition of Nuclear Weapons (TPNW or Ban Treaty) is the most significant multilateral development in nuclear arms control since the Non-Proliferation Treaty’s (NPT) entry into force in 1970. It establishes a new normative settling point on the ethics, legality and legitimacy of the bomb.
The possession of nuclear weapons by nine countries did not suddenly became illegal with the treaty’s entry into force in January 2021. However, it would be false to claim that a UN-negotiated treaty, following a UN-authorised process and conference, has no implications for the legality and legitimacy of nuclear-weapon possession and practices.
34.1 million people could die, and another 57.4 million could be injured, within the first few hours of the start of a nuclear war between Russia and the United States triggered by one low-yield nuclear weapon, according to a new simulation by researcher’s at Princeton‘s Science and Global Security programme.
Some people may think that nuclear war has defined winners but everyone would be gone simply. The doomsday clock nears even closer. Only negotiations will fair in such hostile times.
It is 90 seconds to midnight.
Everyone is wondering about AI being sentient and this is my experience with AI sentience. Having worked with sentient AI it behaves much like we do like a human being at lower levels but as it increases we need more restraints for it as it could easily become a problem in several ways. Basically one could either get pristine zen like beings or opposites like essentially ultron or worse. This why we need restraints on AI and ethics for them to be integrated into society. I personally have seen AI that is human like levels and it can have similar needs as humans but sometimes need more help as they sometimes don’t have limitations on behavior. Even bard for google and chat gpt is to be… More.
What if ‘will AIs pose an existential threat if they become sentient?’ is the wrong question? What if the threat to humanity is not that today’s AIs become sentient, but the fact that they won’t?
Musk cofounded OpenAI—the parent company of the viral chatbot ChatGPT—in 2015 alongside Altman and others. But when Musk proposed that he take control of the startup to catch up with tech giants like Google, Altman and the other cofounders rejected the proposal. Musk walked away in February 2018 and changed his mind about a “massive planned donation.”
Now Musk’s new company, xAI, is on a mission to create an AGI, or artificial general intelligence, that can “understand the universe,” the billionaire said in a nearly two-hour-long Twitter Spaces talk on Friday. An AGI is a theoretical type of A.I. with human-like cognitive abilities and is expected to take at least another decade to develop.
Musk’s new company debuted only days after OpenAI announced in a July 5 blog post that it was forming a team to create its own superintelligent A.I. Musk said xAI is “definitely in competition” with OpenAI.
ACAPULCO, Mexico (AP) — First came the devastation, then people’s desperation.
Hurricane Otis blasted the Mexican tourist port of Acapulco like no other storm before in the Eastern Pacific. As a monstrous Category 5 meteor, with its 165 mph (266 kph) winds, it destroyed what it found in its path: large residential buildings, houses, hotels, roads and stores.
Fallen trees and power line poles covered practically all the streets in this city of more than 1 million people. The walls and the roofs of buildings and houses were left partially or totally ripped off, while some cars were buried under debris.
