Language models can teach themselves to think before speaking.

When writing and talking, people sometimes pause to think.

In hindsight, it seems prophetic that the title of a Nature paper published on 1 March 1974 ended with a question mark: “Black hole explosions?” Stephen Hawking’s landmark idea about what is now known as Hawking radiation¹ has just turned 50. The more physicists have tried to test his theory over the past half-century, the more questions have been raised — with profound consequences for how we view the workings of reality.

In essence, what Hawking, who died six years ago today, found is that black holes should not be truly black, because they constantly radiate a tiny amount of heat. That conclusion came from basic principles of quantum physics, which imply that even empty space is a far-from-uneventful place. Instead, space is filled with roiling quantum fields in which pairs of ‘virtual’ particles incessantly pop out of nowhere and, under normal conditions, annihilate each other almost instantaneously.

However, at an event horizon, the spherical surface that defines the boundary of a black hole, something different happens. An event horizon represents a gravitational point of no return that can be crossed only inward, and Hawking realized that there two virtual particles can become separated. One of them falls into the black hole, while the other radiates away, carrying some of the energy with it. As a result, the black hole loses a tiny bit of mass and shrinks — and shines.

Chinese ambassador Chen Xu called for the high-quality development of artificial intelligence (AI), assistance in promoting children’s mental health, and protection of children’s rights while delivering a joint statement on behalf of 80 countries at the 55th session of the United Nations Human Rights Council (UNHRC) on Thursday.

Chen, China’s permanent representative to the UN Office in Geneva and other international organizations in Switzerland, said that artificial intelligence is a new field of human development and should adhere to the concept of consultation, joint construction, and shared benefits, while working together to promote the governance of artificial intelligence.

The new generation of children has become one of the main groups using and benefiting from AI technology. The joint statement emphasized the importance of children’s mental health issues.

“There is evidence that the youth of today blame the generations before them for the challenges that they and the planet face today,” said Mike Pickett, director of London-based Cazenove Capital, in the report.

The property broker added that housing will continue to be a focus of spending for the next generation, as those born between 1981 and 1996 may have struggled to get on the housing ladder thus far. Even at the highest end of the income ladder, growing a property portfolio is a key concern among those born between 1981 and 1996.

The study shows 23% of female ultra-high-net-worth individuals (UHNWI, valued at $30 million or above) are considering buying a home in 2024, with 21% of male UHNWI expecting to make a similar purchase this year. Wealthy Gen Zers feel the same, with 20% of those born from the mid-1990s to the early 2000s planning an acquisition.
