"Flashbacks" – gravitational waves create "memories" of the universe

Published on May 10, 2019 While the billion dollar detector of the Laser Interferometer Gravitational Wave Observatory (LIGO) watches around the clock for gravitational waves passing through the earth, new investigations have emerged that these waves leave "memories" that could help them recognize them even after the Big Bang, and that they have the potential to inform us about everything …

Black hole-based aliens 'could use GRAVITATIONAL WAVES to communicate' – SHOCK claim | Science | News

The European Space Agency's (ESA) Laser Interferometer Space Antenna (LISA) is scheduled to launch in 2034. The next-generation space instrument aims to capture gravitational waves – tiny ripples through the fabric of space-time. LISA – the world's first dedicated space-based gravitational wave detector – is a staggeringly ambitious project, LISA – the world's first dedicated space-based gravitational wave detector [3] …

The universe probably "remembers" every single gravitational wave

Gravitational waves can leave a lasting impression in the universe. Credit: Shutterstock The Universe "remembers" gravitational waves long after they have passed This is the premise of a theoretical article published on April 25 in the Physical Review D journal. Gravitational waves, weak waves in space and in time, which humanity has discovered only in recent years, tend to pass …

Gravitational waves could leave some strange lasting effects

The faint, flickering distortions of space-time, which we call gravitational waves, are difficult to discover, and we have only succeeded in the last few years. However, scientists have now calculated that these waves may leave more stubborn traces of their passages – traces we may possibly discover. Such traces are called persistent gravitational wave observables. In a new article, an …

DIY gravitational waves with & # 39; BlackHoles @ Home & # 39;

The BlackHoles @ Home project uses highly efficient simulation grids so that binary black hole collisions can be modeled on desktop computers. The black dots represent the horizons of the black hole for two black holes of different mass. Picture credits: Z.Etienne / WVU Researchers hoping to better interpret data from the detection of gravitational waves produced by the collision …

LIGO is looking for gravitational waves again, and scientists hope to learn here

After a year of downtime for hardware upgrades, the Laser Interferometer Gravitational Wave Observatory (LIGO) is operational and will deploy its two detectors on April 1 in Washington State and the US state of Louisiana Virgo collaboration based in Italy. Later this year, the KAGRA detector may also be used in Japan. In combination with the hardware upgrades, the scientists …

The gravitational wave detectors are turned on again and we are turned on

The LIGO Hanford Observatory Photo: Ligo (RIT) The gravitational wave detectors from LIGO and Virgo will continue their search for gravitational waves on April 1. This will be much more sensitive thanks to a series of upgrades for lasers, mirrors and other components. This next round will be a big deal for a variety of reasons. The first two observation …

Earth's gravitational wave detector, LIGO, is online again and now stronger

One of the most remarkable experiments in history – a pair of giant machines observing wave-waves, known as gravitational waves, in space-time, will wake up from a half-year nap on Monday. And it will be about 40% stronger than before. This experiment is called the Laser Interferometer Gravitational Wave Observatory (LIGO). It consists of two huge, L-shaped detectors, which together …
