The Physics Behind the Spanish Blackout
When a grid failure plunged 55 million people in Spain and Portugal into darkness at the end of April, it should have been a wake-up call on green energy. Climate activists promised that solar and wind power were the future of cheap, dependable electricity. The massive half-day blackout shows otherwise. The nature of solar and wind generation makes grids that rely on them more prone to collapse—an issue that's particularly expensive to ameliorate.
As I wrote in these pages in January, the data have long shown that environmentalists' vision of cheap, reliable solar and wind energy was a mirage. The International Energy Agency's latest cost data continue to underscore this: Consumers and businesses in countries with almost no solar and wind on average paid 11 U.S. cents for a kilowatt hour of electricity in 2023, but costs rise by more than 4 cents for every 10% increase in the portion of a nation's power generation that's covered by solar and wind. Green countries such as Germany pay 34 cents, more than 2.5 times the average U.S. rate and nearly four times China's.

Scientists Calculate That the Entire Big Bang Must Have Taken Place Inside a Black Hole
The standard model of cosmology may be the best explanation we've got for why the universe is the way it is and how it all came to be. But it's not the only explanation. Enter black hole cosmology. It's a radical idea which proposes that the Big Bang — the rapid unraveling of an infinitely dense point, believed to have given birth to the cosmos as we know it — actually took place in a black hole, which itself formed inside a larger "parent" universe. Ergo, all of us — and every star, planet, galaxy, and internet rando — are living inside one of these mysterious singularities. Enrique Gaztanaga, lead author of a new study published in the journal Physical Review D and a professor at the Institute of Cosmology and Gravitation at the University of Portsmouth, isn't the first to propose this controversial idea. But his team's research offers a new model for imagining how this hypothetical scenario took place. "Our calculations suggest the Big Bang was not the start of everything, but rather the outcome of a gravitational crunch or collapse that formed a very massive black hole — followed by a bounce inside it," Gaztanaga wrote in an essay for The Conversation. Certainly, there are a lot of holes you could poke in the standard model. Why is there more matter than anti-matter, when the universe should be uniform? Why did the universe undergo a period of "cosmic inflation" in which it expanded at faster than light speeds, then stopped? And why does its present day rate of expansion appear to be different depending on how we measure it? Gaztanaga's main gripe seems to be with our current understanding of a singularity. To him, the idea of the universe starting as a point of infinite density is immensely unsatisfying. "This is not just a technical glitch; it's a deep theoretical problem that suggests we don't really understand the beginning at all," he wrote. Gaztanaga also takes aim at other convenient cosmological constructions like dark energy, which is intended to explain why the universe's expansion is mysteriously accelerating. This hypothetical force is thought to make up 68 percent of the universe but is completely unobservable, leaving room for different-minded scientists to call its existence into question. Rethinking singularities could neatly resolve many of these conundrums. We return to Gaztanaga's paper. "Gravitational collapse does not have to end in a singularity," he wrote for The Conversation. "Our maths show that as we approach the potential singularity, the size of the universe changes as a (hyperbolic) function of cosmic time." This is a bold claim. The consensus is that gravitational collapse — like a star imploding into a black hole — must result in an infinitely dense singularity. What Gaztanaga is arguing happens instead is that the collapse not only halt short of completely crushing the matter, but reverses course — a "bounce," in his terminology. "What emerges on the other side of the bounce is a universe remarkably like our own," Gaztanaga explains. "Even more surprisingly, the rebound naturally produces the two separate phases of accelerated expansion — inflation and dark energy — driven not by a hypothetical fields but by the physics of the bounce itself." It's a fascinating explanation, but there's a lot that remains to be proved. It relies on discounting some very well-established physics behind singularities. The standard model may not be perfect, but it's the standard for a reason. It'll take a lot more to dethrone it, and Gaztanaga is optimistic that future missions like the European Space Agency's ARRAKIHS, which will study invisible structures of dark matter to test the model, could reveal the answers we're looking for.

Don't Count on a Sustained Fed-ECB Decoupling, Schnabel Says
It would be wrong to expect a persistent policy divergence between the US Federal Reserve and the European Central Bank, according to Executive Board member Isabel Schnabel. 'I expect this trade conflict to play out as a global shock that's working for both global demand and supply — we can discuss which of the two effects on inflation is larger because that that determines the net effect,' the German central banker said on Saturday.

Macron Will Visit Greenland This Month, Defying Trump
In a challenge to President's Trump's vow to take control of Greenland, President Emmanuel Macron of France will visit the enormous Arctic island on June 15 with the aim of 'contributing to the reinforcement of European sovereignty.' The French presidency announced the visit on Saturday, saying that Mr. Macron had accepted an invitation from Jens-Frederik Nielsen, Greenland's prime minister, and Mette Frederiksen, the Danish prime minister, with whom it said Mr. Macron would discuss 'security in the North Atlantic and the Arctic.' Greenland, a semiautonomous island that is a territory of Denmark, a NATO ally, has been thrust in recent months from a remote, uneventful existence to the center of a geostrategic storm by Mr. Trump's repeated demands that it become part of the United States, one way or another. 'I think there's a good possibility that we could do it without military force,' Mr. Trump told NBC in March, but added that he would not 'take anything off the table.' Mr. Macron, who has seen in the various provocations directed at Europe by the Trump administration an opportunity for European assertion of its power, will be the first foreign head of state to go to Greenland since Mr. Trump embarked on his annexation campaign this year. JD Vance, the American vice president, visited Greenland in March. The trip was drastically scaled back and confined to a remote military base after the threat of local protests.
