Event Horizon Telescope - First Unveiling of Real Black Hole Image

[Deleted member 14240]

Scientists have obtained the first image of a black hole, using Event Horizon Telescope observations of the center of the galaxy M87. The image shows a bright ring formed as light bends in the intense gravity around a black hole that is 6.5 billion times more massive than the Sun

I just wanted to post it also! That is quite impressive and interesting. I have this weird (maybe subjective) feeling watching this photograph - while I am watching it for a longer time it's vibrating in my eyes

Yes :) Very Exciting times indeed. It measures 40 billion km across... three million times the size of the earth, larger than our entire solar system !!

Plasma scientists and electric universe proponents are rather sceptical about this discovery of a „black hole“ and I share that sceptisism:

Rather than starting a new thread this one seemed relative to the topic of this article where NASA has essentially mapped out the sounds from pressure waves emitting from a galaxy’s center - whether that be black hole or plasmoid.

In this article they apply the method of translation to Perseus and Messier 87 (hence relevances to this thread) to create the “sonifications”. Anyway more below with links to the sonifications to listen to:

Since 2003, the black hole at the center of the Perseus galaxy cluster has been associated with sound. This is because astronomers discovered that pressure waves sent out by the black hole caused ripples in the cluster’s hot gas that could be translated into a note – one that humans cannot hear some 57 octaves below middle C. Now a new sonification brings more notes to this black hole sound machine. This new sonification – that is, the translation of astronomical data into sound – is being released for NASA’s Black Hole Week this year.

In some ways, this sonification is unlike any other done before (1, 2, 3, 4) because it revisits the actual sound waves discovered in data from NASA's Chandra X-ray Observatory. The popular misconception that there is no sound in space originates with the fact that most of space is essentially a vacuum, providing no medium for sound waves to propagate through. A galaxy cluster, on the other hand, has copious amounts of gas that envelop the hundreds or even thousands of galaxies within it, providing a medium for the sound waves to travel.

In this new sonification of Perseus, the sound waves astronomers previously identified were extracted and made audible for the first time. The sound waves were extracted in radial directions, that is, outwards from the center. The signals were then resynthesized into the range of human hearing by scaling them upward by 57 and 58 octaves above their true pitch. Another way to put this is that they are being heard 144 quadrillion and 288 quadrillion times higher than their original frequency. (A quadrillion is 1,000,000,000,000,000.) The radar-like scan around the image allows you to hear waves emitted in different directions. In the visual image of these data, blue and purple both show X-ray data captured by Chandra.

That is pretty low! Here’s more:

In addition to the Perseus galaxy cluster, a new sonification of another famous black hole is being released. Studied by scientists for decades, the black hole in Messier 87, or M87, gained celebrity status in science after the first release from the Event Horizon Telescope (EHT) project in 2019. This new sonification does not feature the EHT data, but rather looks at data from other telescopes that observed M87 on much wider scales at roughly the same time. The image in visual form contains three panels that are, from top to bottom, X-rays from Chandra, optical light from NASA’s Hubble Space Telescope, and radio waves from the Atacama Large Millimeter Array in Chile. The brightest region on the left of the image is where the black hole is found, and the structure to the upper right is a jet produced by the black hole. The jet is produced by material falling onto the black hole. The sonification scans across the three-tiered image from left to right, with each wavelength mapped to a different range of audible tones. Radio waves are mapped to the lowest tones, optical data to medium tones, and X-rays detected by Chandra to the highest tones. The brightest part of the image corresponds to the loudest portion of the sonification, which is where astronomers find the 6.5-billion solar mass black hole that EHT imaged.

More sonifications of astronomical data, as well as additional information on the process, can be found at the “A Universe of Sound” website: A Universe of Sound

This one of Perseus kinda reminds me of the tone in HBOs version of WestWorld thats used to control human. Also got me thinking, a plasmoid at the center of galaxy seems closely aligned to the of a speaker cone just at a macrocosmic level:

The center of the speaker cone is attached to one end, which gets driven back and forth by the moving coil. This cone is held at its edges by an airtight suspension or surround. As the cone moves, it pushes and pulls the surrounding air; by doing so it creates pressure waves in the air, called sound.

Not much more to add, but wonder what affect the sounds may have through the surround space - if any? On the other hand it seems like a rather contrived approach to create a “musical composition” from a galaxy gas. Anyway the thought of galaxies as giant speakers with their own “sound”, tune, or frequency is fascinating to consider…

Hmmm... the alleged sound of the black hole sounds a lot like some of the 'strange sounds' recorded in recent years coming from an empty sky, sounding like trumpets, grinding metal, etc.

All the “strange” sounds is easily explained. The ear hears two different things, the sound or pressure waves in the air and it can also hear EMF. That’s because the ear converts those pressure waves into electronic signals via liquid piezoelectric crystals. There’s some information about it in the book The Invisible Rainbow but the real proof is probably in the book by George Offutt that’s out of print called The Electro Model of the Auditory System.

So people can literally hear EMF, which has been proven in many experiments. I just mention this because if all the forum members start hearing these “strange sounds”, it’ll be easier to understand if they take on board the knowledge of how our auditory system works.

It also makes one want to look at the relationship between sound and EMF, were the people at Stonehenge really hearing sound pressure waves? Or was it all EMF?
