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

Umm you can not actually see or capture a black hole on film. Because nothing, not even light escapes them. What they are able to photograph is the energy being drawn into it.

[Aktungbby]

/\ ...or so we have been told! Under the universal rule of "pic or it didn't happen" there is now room for doubt??:hmmm:

[Mr Quatro]

It's like the GDU of the universe ... :yep:

Does anyone know how many of these black holes excist?

[Commander Wallace]

I have been following these developments. We know so little about Black Holes, it's difficult to comprehend the power they have. I have watched science shows that tried their best to describe what science knows.It has been suggested that there are such things as roving Black holes as well. The other incredibly destructive force is a magnetar


Quote: The density of the interior of a magnetar is such that a tablespoon of its substance would have a mass of over 100 million tons. Magnetars are differentiated from other neutron stars by having even stronger magnetic fields, and by rotating comparatively quicker. Most neutron stars rotate once every one to ten seconds, whereas magnetars rotate once in less than one second. A magnetar's magnetic field gives rise to very strong and characteristic bursts of X-rays and gamma rays.

These images and discoveries are amazing.

[Rockstar]

Don't think we could ever count the number. Unlike what the click bait may say we can't actually see them. Unless we can witness the effects they have on visible light and matter around them we wouldnt know of their existence

[vienna]

Technically, it is not possible to photograph any hole, since all holes are essentially empty spaces and have no mass of their own; the only evidence we have is either the surrounding perimeter and/or the observation of an object 'falling' into the 'hole'...

And surprise surprise, it looks like a black hole.

[bstanko6]

Since we can only view things from our little, minuscule, insignificant perspective in this over godly large universe, there is way too much information to seek to justify any answers of what black holes are, or were, or where.

So I just don’t believe it is a black hole, or if they exist.

[Skybird]

In the end, nothing what we see, hear, taste, feel, is like what our senses communicate it as to the brain, wich turns the photon storm on the retina into an electrons storm inside the neural sponge inside what we consider to be a.) "our" b.) "heads".

As Paul Watzlawick once put it so remarkably nice: "Die Wirklichkeit wird von uns nicht ge-funden, sondern er-funden." (Reality does not get discovered but invented by us). Its all a dance of ever-changing temporary structures of - well, of whatever it is. Usually we put in the word "energy" here as a joker.

The brilliance of the image of that black hole maybe not so much lies in what it tells a black hole is, but what it tells it is not.

And keep in mind that it were radio telescopes that got networking together here. They do not provide a "visual-optical" image that compares to that of an optical telescope. In a way, it is an illustration of abstract data, systematically constructed and not fully subjective like that of a painting artist, still: a visualising model of something. Like many interstellar photoghraphies are artifical combinations of data from various different kinds of telescopes and their according wavelengths as well. They visual output format is constructed, not objectively observed.

Considering how very different one and the same tiny place in the universe may look to different life forms like bats with ultrasonic orientation, mammals with eyes, blind animals with good ears, tiny insects with a completely different perception of time contexts and time passing than a human, I wonder how much more there is around us everywhere that exist parallel to us maybe right now, and we just are unable to perceive the other, and recognise the others' existence. Elves, anyone? :)

The universe is a strange place. The mere fact that something exists at all instead of just nothing being there, is strange. But maybe only when yto make sense of it from inside the contexts of this universe, and no other possible one with different natural laws, may it be real, or just a not materialised potential.


We all are at the same time part of the same one-ness, but create our own individual representation of it that we then believe to live in. I believe since many years now that the key to exploring and understanding the outer space is - to understand our inner space. Any maybe we will find in the end that both are one and the same.

First of all, we would need to know how big the universe is.


Get back to us when you got that figured out. :D:D:D

The neat thing about infinity is that even a small percentage of infinity is still infinity. :o

[Rockstar]

The observable universe is a mere of 46.5 billion light years distance from earth. In our observable universe there is thought to be somewhere around 2,000,000,000,000 (trillion) galaxies. Many of which humans will never see because they are moving away from us. According to Alan Guth's Theory of Cosmic Inflation if it is assumed cosmic inflation began 0.0000000000000000000000000000000000001 seconds after the big band. It would suggest the size of the universe could be 150 sextillion times larger than the observable universe. One can only imagine how many 'black holes' there are.

Below a photograph of earth (The Pale Blue Dot) taken by Voyager 1 February 14th 1990 at a distance of 3.7 billion miles from earth.
https://upload.wikimedia.org/wikipedia/commons/7/73/Pale_Blue_Dot.png
We succeeded in taking that picture [from deep space], and, if you look at it, you see a dot. That's here. That's home. That's us. On it, everyone you ever heard of, every human being who ever lived, lived out their lives. The aggregate of all our joys and sufferings, thousands of confident religions, ideologies and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilizations, every king and peasant, every young couple in love, every hopeful child, every mother and father, every inventor and explorer, every teacher of morals, every corrupt politician, every superstar, every supreme leader, every saint and sinner in the history of our species, lived there on a mote of dust, suspended in a sunbeam.

The earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that in glory and in triumph they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of the dot on scarcely distinguishable inhabitants of some other corner of the dot. How frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Our posturings, our imagined self-importance, the delusion that we have some privileged position in the universe, are challenged by this point of pale light.

Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity -- in all this vastness -- there is no hint that help will come from elsewhere to save us from ourselves. It is up to us. It's been said that astronomy is a humbling, and I might add, a character-building experience. To my mind, there is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly and compassionately with one another and to preserve and cherish that pale blue dot, the only home we've ever known. - Carl Sagan, Excerpted from a commencement address delivered May 11, 1996

Sorry, but that is a logical fallacy, I would say. A part of infinity mathematically is "infinity minus X". Thus: a finite quantum is left, and a finite quantum is what forms just the part.

I would conclude that just a part of infinity still being infinite, is something unimaginable and impossible.

You cannot divide or multiply, add to and substract from infinity. Its infinite. Alter it on a quantitative level, and it is not finite anymore. AND WAS NOT FROM THE BEGINNING ON.

[Sailor Steve]

Stop being so pedantic. It doesn't suit you.
A lot of people would say it suits me, and I like Rockstar's summation. I don't know if the Universe is infinite, and I certainly never will, but as far as we can tell it might as well be.

[Rockstar]

Lol I had look that word up. But I don't need to pretend to be a rocket scientist to know a black hole cannot be photographed. Alerting others to that fact was why I clicked on the clickbait headline which may lead others too believe it could.
Also, it pays to know these kinds things especially since my hobby is astrophotography. Helps prevent me from looking like an idiot in front of others at star parties. Part of my library includes Deep Sky Imagining Primer by Charles Bracken a very good but difficult read for beginners.

[Dowly]

But I don't need to pretend to be a rocket scientist to know a black hole cannot be photographed.
You are splitting hairs. No one was expecting an image of the event horizon, even less the singularity itself, but an image of a black hole which we absolutely got. The image shows everything expected; the material disk, the distortion of the disk and the dark area caused by the black hole in the center.

If it's not an image of a black hole, then what is it in your mind? :)

Wormholes, black holes, and the likes...

The reasoning for the chosen depiction of both, are interesting!?

[Mr Quatro]

If the earth is flat, as some still believe ... in fact there is even a flat earth society ... :yep:

Then how come everything we can see with our naked eye in our solar system and beyond with telescopes and now a far Horizon camera ... is round?

Time for this flat earth society to give in and agree that not only is everything round, but is by intelligent design. :hmmm:

Which is another point no one can prove.

[Mr Quatro]

Yep! :yep: It's real I looked it up they are still in belief that the world is flat :o

https://www.themanual.com/travel/flat-earth-cruise-2020-details/


Despite all evidence to the contrary, for more than a century the Flat Earth Society has maintained that our planet is not, indeed, a sphere. Instead, they posit that it’s a massive, flat disc with the Arctic Circle at its center and Antarctica as a towering, 150-foot-tall ice wall around Earth’s rim. They’re confident NASA is a black ops government agency whose sole purpose is to guard this wall from naysayers, dragons, and kraken. They also firmly believe gravity is an illusion, we’re orbited by an invisible “antimoon,” and the sun is only 3,000 miles above the Earth. The society dismisses all photographic and scientific evidence to the contrary as fake.

[mapuc]

I who are very interested in our univers and the science surrounding it, was very excited when I saw the picture.

The little knowledge I have gained by watching all these documentaries about our univers told me or trying to remember what I have learned about black hole and the all the things around this hole.

Everything that is pulled into the singularity has to go somewhere doesnt it . Does the singularity get bigger or does the matter that makes up the singularity have mass and no mass at the same time ? or does the matter become just space (the blackness) . Does the event horizon get bigger over time ? These are questions i need to know .

I want the bloody EU to disappear into it...Hello Mr Black Hole I got £20 for you to do a little job for me. :DL

On a more serious note not bad but we need a much better picture.

The mass does not seize to exist, it accumulates inst5ead. So the gravity pull of the black hole grows stronger, I think. The picture they made, is not a photo of the hole itself, becasue sinc enothign escapes form a blakc hole, you cannbot catch up any emitting patrtciles, waves, whatever from it. Its like with "seeing" an insivisble man. We do not see the invisible man, but we can see the shadow he casts on the wall.



They said that the data on their harddrives had severla petabytes. Loads and loads of harddrives, several hundred kilograms in total weight. From this data, the images were constructed. Done four times, by four different teams. All teams' final results were not too different form each other, but different they were, which shows that these images are not "objective" visual photographies of somethign, but are artificial creations, thus I called them "illustrations". It is a data-based illustration of a black hole's "shadow" that its invisible presence casts on the matter and space around it.

In my current state of mind I perceive a shopped image of light being bent by strong gravitational forces. Though I have on occasion altered my perception of time and sometimes reality then got the munchies after smoking some dank purple hindu :D

Sky speaks the truth even the colors are computer generated based on the temperture and then the yellows and the reds are added in. I saw a series of screens from the other contributing data gathering space experts and they were not all perfect like the one in the OP ... More questions than answers, but that is a good thing for todays youth to help then get involved in space science.

Can you imagine the amount of math it took to get a space craft with the ability to take these images of a black hole to the point in time that it is in right now? :up:
