Cosmic ‘Lighthouses’ That Beam Gamma Rays Could Reveal Gravitational Waves All Around Us
A team of astronomers have compiled 12.5 years of data from the Fermi Gammy-ray Space Telescope to form a gamma-ray pulsar timing array, a system of cosmic lighthouses that could help reveal ripples in spacetime.

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…

Mirrors That Detect Ripples in Space-Time Were Frozen to Near Absolute Zero
A team of physicists say they’ve managed to nearly freeze the motion of atoms across four suspended mirrors. It’s a mind-twisting feat that strains the very definitions of seemingly simple words like “object” and “temperature.” So buckle up.
