    How to spot tiny black holes that might pass through the solar system 

    Flybys of primordial black holes may occur once a decade. Tweaks to the orbits of planets and GPS satellites could give away their presence.

    In an epic cosmology clash, rival scientists begin to find common ground 

    Different measurements of the cosmic expansion rate disagree. The James Webb telescope could determine whether that disagreement is real.

    The universe may have a complex geometry — like a doughnut

    Physicists haven’t yet ruled out the possibility that the universe has a complicated topology in which space loops back around on itself.

    The largest 3-D map of the universe reveals hints of dark energy’s secrets

    A year of data from DESI, the Dark Energy Spectroscopic Instrument, suggests that, contrary to expectations, dark energy might vary over time.

    Did the James Webb telescope ‘break the universe’? Maybe not

    There’s no need for strange new physics to explain anomalously bright, massive galaxies seen by JWST, Hubble data suggest.
