First ever image of a black hole revealed

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.

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

Mr Quatro · 04-10-19, 10:42 AM

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

Does anyone know how many of these black holes excist?

Commander Wallace · 04-10-19, 10:55 AM

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.

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

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.

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.

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.

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

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.

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

^ if that is Earth where is the sun and other planets? Most are much bigger!!

Stop being so pedantic. It doesn't suit you.
