AI could accelerate the hunt for new physics, but sometimes it knows too much to see what’s right in front of it. Artificial intelligence could make it much cheaper and faster to search for new laws of physics, according to a new study published in the Journal of Cosmology and Astroparticle Physics (JCAP). But the [...]

Astronomers have discovered a powerful “galaxy-killing wind” in the early universe that may help solve one of the biggest mysteries in modern astronomy: why so many massive galaxies stopped forming stars much earlier than scientists expected. The discovery suggests that some young galaxies grew rapidly and then died just as quickly, not because of exotic […]

A new detector-based method clarifies how gravitational waves should be measured in an evolving universe. Imagine trying to measure a ripple on the surface of a pond while the pond itself is slowly changing shape. That is the challenge scientists face when they study gravitational waves not as isolated signals from colliding black holes, but [...]
