Scientists Propose Webb Telescope Has Detected Stars Powered by Dark Matter
Astronomers looking at ancient light seen by the Webb Space Telescope have found three pinpricks that they think could be “dark stars,” theoretical objects powered by dark matter. Dark matter makes up about 27% of the universe; its partner in ambiguity, dark energy, makes up about 68%. You can do the math: we know stunningly…

Black Holes Could Be Expanding Along With the Universe
In 2015, two black holes were caught merging when the ripples in spacetime they created were detected on Earth. Since then, gravitational wave detectors have found many more of these mergers, broadening our understanding of the most epic collisions known to science. Now, a team of astrophysicists examining data from these detections are proposing that…
