First ever image of a black hole revealed

[Dowly]

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]

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

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.

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'...

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

Nice!

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.

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


Get back to us when you got that figured out.

[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.

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

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.

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.
