A decade ago, scientists first detected ripples in the fabric of space-time, called gravitational waves, from the collision of two black holes. Now, thanks to improved technology and a bit of luck, a newly detected black hole merger is providing the clearest evidence yet of how black holes work — and, in the process, offering long-sought confirmation of fundamental predictions …

In February 2016, scientists at the Laser Interferometer Gravitational wave Observatory (LIGO) announced the first detection of gravitational waves (GW). These ripples in space time, originally predicted by Einstein’s Theory of General Relativity, are caused by the merger of massive objects (like neutron stars and black holes). Since then, gravitational wave observatories like LIGO, VIRGO, and the Kamioka Gravitational Wave …

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 …

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 …

‘Black hole morsels’: A Stephen Hawking theory could reveal strange new objects that challenge physics  Live Science Source link

In 1995, renowned physicist Stephen Hawking made several bold predictions about what life would look like in 2025. Now that we’ve reached this milestone year, it’s fascinating to evaluate which of his forecasts hit the mark and which ones missed. The brilliant cosmologist, who lived with ALS for most of his life, shared these predictions during a BBC television program called …
