#DidYouKnow: #Gravitational #Waves are 'ripples' in space-time caused by some of the most violent and energetic processes in the Universe.

Albert #Einstein predicted the existence of gravitational waves in 1916 in his general theory of relativity.

“These #gravitational waves are cousins to the echoes from black hole collisions. But whereas collisional waves vibrate in milliseconds, it might take decades for a single one of these low frequency gravitational waves to pass by at the speed of light.”

Low frequency waves, you say? How do I connect that up to my #eurorack?

#TopicOfTheDay: #Gravitational #Lensing occurs when a massive celestial body — such as a galaxy cluster — causes a sufficient curvature of spacetime for the path of light around it to be visibly bent, as if by a lens.

The body causing the light to curve is accordingly called a gravitational lens.

#Orbital motion - there are exotic possibilities such as knife-edge #orbits, in which the #satellite can be made to execute an arbitrarily large number of nearly circular orbits, after which it flies back outward. https://en.wikipedia.org/wiki/Schwarzschild_metric#Orbital_motion

In #Einstein's theory of general #relativity, the #Schwarzschild solution is an exact solution to the Einstein field equations that describes the #gravitational field outside a spherical mass

When a #spacecraft is launched from #Earth 🌍, its forward #velocity combined with the gravitational pull of Earth cause it to travel in a curved path. As the spacecraft heads toward another #planet 🪐, the #gravitational pull of that planet factors in to the path the spacecraft takes. https://www.jpl.nasa.gov/edu/teach/activity/lets-go-to-mars-calculating-launch-windows

The spacecraft departs #Earth 🌍 at a #speed of about 39,600 kph. The trip to #Mars will take about seven months and about 480 million kilometers https://mars.nasa.gov/mars2020/timeline/cruise

The Challenge of Weird Black Hole Mergers
https://skyandtelescope.org/astronomy-news/weird-black-hole-mergers/

When spacetime shivers last only a fraction of a second — as in the case of the massive-black-hole merger GW190521 — astronomers struggle to uncover their origins. The post The Challenge of Weird Black Hole Mergers appeared first on Sky & Telescope .

I was stopped by the thought; do the #Rocks remember when they were free? Long before The Cooling and biology, when they flowed through & across the #gravitational fields that held them in a molten sphere?

And that, what is for us, the hottest day at the hottest point of the hottest desert, remains for the Rocks, the #IceAge.
