Good morning RP. Today's video clip (0:35) is titled "Simulation: Two Black Holes Merge." Coming on the heels of the first image of an event horizon last week, you can see how gravity lenses the light from behind the two black holes as they merge. The LIGO (Laser Interferometer Gravitational-Wave Observatory) and EGO (European Gravitational Observatory, operators of the Virgo gravitational inteferometer) provided data for this simulation. Information brought by gravitational waves can now be added to those provided by current telescopes and their study of the electromagnetic spectrum (visible light, microwaves, radio waves, infrared, ultraviolet, X-rays and gamma rays).

Two Black Holes Merge into One

Thank you, my friend Maj William W. 'Bill' Price for posting the NASA simulated video of the day for April 14, 2019 entitled "Simulation: Two Black Holes Merge."
https://www.youtube.com/watch?v=I_88S8DWbcU
"A computer simulation shows the collision of two black holes, a tremendously powerful event detected for the first time ever by the Laser Interferometer Gravitational-Wave Observatory, or LIGO. LIGO detected gravitational waves, or ripples in space and time generated as the black holes spiraled in toward each other, collided, and merged. This simulation shows how the merger would appear to our eyes if we could somehow travel in a spaceship for a closer look. It was created by solving equations from Albert Einstein's general theory of relativity using the LIGO data.
The two merging black holes are each roughly 30 times the mass of the sun, with one slightly larger than the other. Time has been slowed down by a factor of about 100. The event took place 1.3 billion years ago.
The stars appear warped due to the incredibly strong gravity of the black holes. The black holes warp space and time, and this causes light from the stars to curve around the black holes in a process called gravitational lensing. The ring around the black holes, known as an Einstein ring, arises from the light of all the stars in a small region behind the holes, where gravitational lensing has smeared their images into a ring.
The gravitational waves themselves would not be seen by a human near the black holes and so do not show in this video, with one important exception. The gravitational waves that are traveling outward toward the small region behind the black holes disturb that region’s stellar images in the Einstein ring, causing them to slosh around, even long after the collision. The gravitational waves traveling in other directions cause weaker, and shorter-lived sloshing, everywhere outside the ring."
Thank you, my friend TSgt Joe C. for mentioning me.

Maj William W. 'Bill' Price, that was absolutely AWESOME!!! Only a Simulation, but so realistic... Of course this was based on two separate data sources; The LIGO (Laser Interferometer Gravitational-Wave Observatory) and EGO (European Gravitational Observatory. Just watching this video in full screen (I cast it to my 24" Acer Monitor, but didn't try it on my 50" TV in my office... It was outstanding on my Acer Monitor! Thank you for this POD!!! Have a great day, Bill!

Black holes such as those: have always scared me, Bill. That doesn't mean that I cannot bid you a VERY HAPPY SUNDAY, BILL! Maj William W. 'Bill' Price

I certainly don't share things like this to frighten, SPC Margaret Higgins. You and I share the same Creator with a black hole. How can something stronger than a black hole love us? I don't understand how that is possible, but it is. Those thoughts help me put my fears to rest. I hope they can help you do so too.
