Any Single Galaxy Reveals the Composition of an Entire Universe
In computer simulations of possible universes, researchers have discovered that a neural network can infer the amount of matter in a whole universe by studying just one of its galaxies. The post Any Single Galaxy Reveals the Composition of an Entire Universe first appeared on Quanta Magazine
A group of scientists may have stumbled upon a radical new way to do cosmology. Cosmologists usually determine the composition of the universe by observing as much of it as possible. But these researchers have found that a machine learning algorithm can scrutinize a single simulated galaxy and predict the overall makeup of the digital universe in which it exists — a feat analogous to analyzing a...
