Facebook Tweet Email Link Multiple historically Black colleges and universities in the South were on lockdown or canceled classes on Thursday over potential threats. Hampton University, Virginia State University, Bethune-Cookman University and Alabama State University were on lockdown after receiving “potential threats to campus safety,” according to posts on school social media pages. The lockdowns come one day after Charlie …

But the final reverberations as the newly formed black hole settled into its new state, aka the ringdown, from that first event were significantly fainter, and scientists were unable to distinguish between the ringing from the initial collision and the ringdown. For GW250114, LIGO’s improved sensitivity meant that scientists could measure the frequency and duration of the merged black hole’s …

Facebook Tweet Email Link Astronomers have detected a collision between two black holes in unprecedented detail, offering the clearest view yet into the nature of these cosmic oddities and confirming long-held predictions made by legendary physicists Albert Einstein and Stephen Hawking. The event, dubbed GW250114, became known in January when researchers spotted it with the Laser Interferometer Gravitational-Wave Observatory (LIGO) …

When two black holes merge, they release gravitational waves. These waves can be picked up by detectors on Earth, allowing scientists to better understand them. Maggie Chiang/Simons Foundation hide caption toggle caption Maggie Chiang/Simons Foundation On September 14, 2015, physicists attained the long-sought goal of detecting gravitational waves, the shockwaves spewed out by such cataclysmic events as the violent merger …

Ten years ago, scientists heard the universe rumble for the first time. That first discovery of gravitational waves proved a key prediction from Albert Einstein’s theory of general relativity and began a new era of astronomy. Now, a new gravitational-wave discovery marks the anniversary of this major breakthrough. Published today in Physical Review Letters, it puts to the test a …

The Laser Interferometer Gravitational-Wave Observatory (LIGO) is celebrating 10 years of cutting-edge gravitational wave science by confirming predictions made by physics luminaries Albert Einstein, Stephen Hawking and Roy Kerr — and potentially revealing a path toward a theory of quantum gravity. LIGO achieved this latest milestone by detecting gravitational waves, or tiny ripples in spacetime. The existence of gravitational waves …

Small black holes making a meal out of companion stars are surprisingly messy eaters, astronomers using a Japanese space telescope have discovered. Scientists have known for some time that when supermassive black holes — those with masses millions or billions of times that of the sun — devour matter, such as surrounding gas and dust or even an unfortunate passing …

Too many things in our life need to get plugged in. Our phones, watches, headphones — damn near everything that isn’t attached to us needs to be charged at the end of the day. And now that it’s gotten even more complicated that everything is moving away from USB-A to USB-C. Sure, USB-C is a better standard and can do …
