The structure of the test site is also exciting. Each of the satellites contains a floating cube made of gold and platinum, the size of which would fit easily into a hand. Laser light in each of the satellites measures the distance to the other two test objects. If a gravitational wave, basically a shake …
The research team models the various signatures of a kilonova explosion. Imagine the universe’s most powerful fireworks: two ultra-dense stars crashing together, creating not just dazzling light but rippling spacetime and forging the gold in your ring. This cosmic dance, witnessed in 2017, wasn’t just a spectacle. It was a forge, churning out the precious …
An international team of researchers have developed a method to model the observable signs of a kilonova explosion from the explosive merger of two orbiting neutron stars. This could help them describe what exactly happens during a merger, how nuclear matter behaves under extreme conditions and why the gold on Earth must have been created …
When a violent shake of space-time hit the Earth on August 17, 2017, it was not only possible to measure gravitational waves for the first time, which had previously only existed in theory. It also provided scientists around the world with countless pieces of valuable data. And the source of the gigantic explosion was identified …
Black holes are extremely simple objects. They are described by two numbers: its mass and angular momentum (or “spin”). However, the same does not apply to stars or planets, which are made of more complex matter distributions. Black holes also hold a characteristic spectrum of gravitational wave signals, which have specific frequencies and fade out …
New Delhi: The scientific community was filled with excitement on June 28th when the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) Physics Frontiers Center announced groundbreaking findings. Comprised of over 190 scientists from the US and Canada who use pulsars to detect gravitational waves, NANOGrav revealed “compelling evidence” for gravitational waves that oscillate over …
