Possible Detection of Dark Matter in a Black Hole Collision Event
Daniel FischerGreenlight for next two ESA #Scout missions, Hibidis and SOVA-S: https://www.esa.int/Applications/Observing_the_Earth/FutureEO/Greenlight_for_next_two_ESA_Scout_missions - the latter is "Satellite Observation of Waves in the Atmosphere – Scout" with a shortwave infrared imager to provide near-global daily observations of #GravityWaves at an altitude of between 80 km and 120 km by measuring the intensity of #airglow, a faint emission of light produced by a chemical reaction in the atmosphere.
Greenlight for next two ESA Scout missions
The European Space Agency is expanding its growing fleet of Earth-observing science Scout missions with the selection of two new satellites: Hibidis and SOVA-S.Chosen from four final competing concepts, these missions will tackle very different but equally pressing scientific questions – from biodiversity below forest canopies to the effects of atmospheric gravity waves high above Earth.
rdmThis evening I learned the following bizarre things:
0/ Colliding massive objects create gravity waves (this I already knew).
1/ When spinning black holes collide, they experience an acceleration at right angles to the sum of the spins.
2/ The bigger the black holes, the greater the acceleration and resulting speed.
3/ When this happens with galactic core supermassive black holes, this can exceed the escape velocity of the galaxies.
4/ When one of these high-speed supermassive black holes encounters a dust or gas cloud, it creates a contrail of stars! And we can see these star-contrails - straight lines of stars, scattered across the cosmos!
Thank-you Professor David Blair!

ethanmc68When neutron stars merge, things get messy
What happens when the densest objects in the universe collide? A neutron star merger is a cosmic forge that creates heavy elements like gold and platinum, but it also unleashes "messy" gravitational waves and gamma-ray bursts that can sterilize nearby solar systems. We look at the violent physics of a kilonova.

Gravitational waves may prove black holes' quantum effect and resolve the dark matter problem
Black hole quantum effects are usually thought to be too small to have any observable signatures. This is indeed the case for heavy black holes, such as the ones detected via gravitational waves by LIGO in 2015. These black holes have mass of a few tens of solar mass and, consequently, their Hawking radiation is negligible.
Nicole SharpRevealing Gravity Waves
Severe weather — like thunderstorms, tornadoes, and hurricanes — can push air upward into a higher layer of the atmosphere and trigger gravity waves. Aboard the International Space Station (ISS), the Atmospheric Waves Experiment (AWE) instrument captures these waves by looking for variations in the brightness of Earth’s airglow (above). Recently, when Hurricane Helene hit the southeastern United States, AWE caught a series of gravity waves some 55 miles up, pushed by the storm (below). It’s incredible to see these long-ranging ripples spreading far beyond the heart of the storm. (Video credits: NASA Goddard and Utah State University)
