The effect, known as the Hubble Tension, has been confirmed by James Webb Space Telescope observations. Also, despite near daily warnings of food recalls, 2024 hasn’t been that different from previous years.The Universe Is Expanding Faster Than ExpectedThere’s still a lot to be learned about the physics of our universe—and one of the most perplexing ideas is something called the Hubble Tension. That’s an observation, made around a decade ago, that the universe seems to be expanding faster than it should be according to cosmologists’ understanding of its earliest days. Now, two years of James Webb Space Telescope observations of supernovae have confirmed those previous measurements made by the Hubble telescope, meaning that the puzzle isn’t just due to some instrumental error.Casey Crownhart, climate reporter at MIT Technology Review, joins Kathleen Davis to talk about that finding and other stories from the week in science, including a new quantum computing chip from Google, efforts to improve electrical cont
