AI's Impact on Science

This year will be a big one for quantum computing, at least according to the United Nations: 2025 is officially the “International Year of Quantum Science and Technology,” a worldwide initiative to raise awareness of technological progress and encourage new advances.

The cloud, named Eos, is chock-full of molecular hydrogen and possibly rife with star-forming potential in the future.

Over the past decade, two very different ways of calculating the rate at which the universe is expanding have come to be at odds, a disagreement dubbed the Hubble tension, after 20th-century astronomer Edwin Hubble. Experts have speculated that this dispute might be temporary, stemming from subtle shortcomings in observations or analyses that will eventually be corrected rather than from some flawed understanding of the physics of the cosmos. Now, however, a new study that relies on an independent measure of the properties of galaxies has strengthened the case for the tension. Quite possibly, it’s here to stay.

Modern science wouldn’t exist without the online research repository known as arXiv. Three decades in, its creator still can’t let it go.
