First black hole image claimed

If NASA faked the moon landings, does the agency have any credibility at all? Was the Space Shuttle program also a hoax? Is the International Space Station another one? Do not dismiss these hypotheses offhand. Check out our wider NASA research and make up your own mind about it all.

First black hole image claimed

The media is crowing today about what is being called the first image of a "black hole." Buried in the fine print is the fact that the image isn't a photograph from, say, the Hubble telescope but, according to the team behind the image, is constructed from a vast array of data and pieced together by an algorithm:
"While the task of coordinating telescopes and collecting radio signals was complex and impressive, it’s the algorithm development that is likely to have long-term impacts on technology, said Jonathan Weintroub, an electrical engineer who developed physical instrumentation for the EHT project. His team used off-the-shelf products and existing telescopes to essentially build a globe-spanning telescope like a kid might build a Lego model. That’s no small feat. The final system was able to collect and store 5 petabytes of data. If 1 byte were a 2-foot-by-2-foot tile, then 1 petabyte would cover the whole Earth. But the job of converting that data into an image required the creation of entirely new software tools.

The problem: That global megatelescope (while obviously awesome) is still producing data as holey as a slice of Swiss cheese. The telescopes are collecting photons — packets of light — that fall from space like the proverbial pennies from heaven. But even working together, they can only catch a tiny sampling of those photons. Reconstructing an image from that sparse data set represents a challenge as massive as the black hole itself, Weintroub told me. The algorithms EHT researchers developed were crucial to solving that challenge, and their solution could have wide-ranging implications."

Even if the algorithm used is correct and assuming the image isn't falsified altogether (a very strong possibility given the cringeworthy media circus around this), how do we know that this ring of light is a "black hole”? I'm quite confident that it is not, since Einstein's relativity pseudoscience (upon which the theory of black holes depends) is a debunked hoax.

Hot off the press:
Science fact: Astronomers reveal first image of a black hole
By SETH BORENSTEIN

WASHINGTON (AP) — Humanity got its first glimpse Wednesday of the cosmic place of no return: a black hole.
And it’s as hot, as violent and as beautiful as science fiction imagined.

In a breakthrough that thrilled the world of astrophysics and stirred talk of a Nobel Prize, scientists released the first image ever made of a black hole, revealing a fiery doughnut-shaped object in a galaxy 53 million light-years from Earth.

“Science fiction has become science fact,” University of Waterloo theoretical physicist Avery Broderick, one of the leaders of the research team of about 200 scientists from 20 countries, declared as the colorized orange-and-black picture was unveiled.

The image, assembled from data gathered by eight radio telescopes around the world, shows light and gas swirling around the lip of a supermassive black hole, a monster of the universe whose existence was theorized by Einstein more than a century ago but confirmed only indirectly over the decades.

Supermassive black holes are situated at the center of most galaxies, including ours, and are so dense that nothing, not even light, can escape their gravitational pull. Light gets bent and twisted around by gravity in a bizarre funhouse effect as it gets sucked into the abyss along with superheated gas and dust.

The new image confirmed yet another piece of Einstein’s general theory of relativity. Einstein even predicted the object’s neatly symmetrical shape.

We have seen what we thought was unseeable. We have seen and taken a picture of a black hole,” announced Sheperd Doeleman of Harvard, leader of the project.

Jessica Dempsey, another co-discoverer and deputy director of the East Asian Observatory in Hawaii, said the fiery circle reminded her of the flaming Eye of Sauron from the “Lord of the Rings” trilogy.

Albert Einstein was right: Takeaways from first image of massive black hole

WASHINGTON - Black holes are cosmic prisons, where nothing escapes, not even light. But lots did come out of Wednesday’s first image of the shadowy edge of a supermassive black hole. Here are four things we learned:

Seeing is believing

Scientists have known for decades that black holes exist, but only indirectly. Three years ago, they essentially heard the sound of two smaller black holes crashing together to form a gravitational wave.

The image revealed Wednesday for the first time showed the edges of the black hole — the point of no return, called the event horizon.
There actually were a few academic holdouts who denied black holes existed, but now they can’t, said Boston University astronomer Alan Marscher, who was on one of four imaging teams.



Einstein proved right again

Each major astrophysics discovery of the last few decades tends to confirm Albert Einstein’s general theory of relativity, the comprehensive explanation of gravity that the former patent clerk thought of in 1915.

On Wednesday, Einstein’s predictions about the shape and glow of a big black hole proved right, and astronomer after astronomer paid homage to the master.

Today general relativity passed another crucial test,” said University of Waterloo astronomer Avery Broderick, a co-discoverer. “The Einstein equations are beautiful. So often in my experience, nature wants to be beautiful.”

It sounds strange to keep saying Einstein is right, but every time his general relativity theory is confirmed, “we kill a cloud of alternative theories” and gain better understanding how to create an even more comprehensive theory of physics, said Ethan Vishniac of Johns Hopkins University, who wasn’t part of the discovery team.

A German astronomer, Karl Schwarzschild, in 1916 predicted the theoretical possibility of black holes, based on Einstein’s general relativity, though he did not believe they could actually exist.

Gravity is powerful

The black hole that scientists took a picture of is 55 million light-years away at the center of a massive galaxy called M87 in the nearby Virgo galaxy cluster, and it is far bigger than anything in the Milky Way. Its mass — the chief measurement of a black hole — is 6.5 billion times more than our sun’s. The event horizon stretches about the breadth of our solar system.


Working together works

The project succeeded because of international cooperation among 20 countries and about 200 scientists at a cost of $50 million to $60 million, according to the National Science Foundation.

'I Was in Total Disbelief': Katie Bouman, the 29-Year-Old Computer Scientist Behind the EHT, on the First Black Hole Image
By Hannah Osborne On 4/11/19

Scientists have revealed the first-ever image of a black hole. The picture is the result of a global collaboration in which scientists linked together telescopes virtually to create one, huge, Earth-sized telescope.

The observation period, in April 2017, was followed by almost two years of data processing, and the resulting image has now been made public.
To mark the occasion, the Smithsonian Channel will be showing an hourlong documentary about the Event Horizon Telescope project. Black Hole Hunters follows the scientific team behind the EHT, showing a journey that would culminate in the groundbreaking announcement. It airs on April 12 at 9 p.m. ET.

Ahead of the documentary, Newsweek interviewed EHT scientist Katie Bouman about what obtaining an image of a black hole actually means. Bouman is the computer scientist who developed one of the algorithms used to decode the data.

I can't deny it. Katie Bouman's "marvelous" achievement is certainly worthy of a Nobel Prize.

The GIGO Principle in Machine Learning
Govind Chandrasekhar
4 July 2017

And its implications for PMs, designers, salespeople and data scientists

Garbage-In-Garbage-Out is the idea that the output of an algorithm, or any computer function for that matter, is only as good as the quality of the input that it receives.

The principle underlying GIGO is essential when it comes to the real world deployment of algorithms. And with the increasing usage of ML in everything from public-facing APIs to the underlying services that power public-facing applications, awareness and assimilation of this principle is as important now as it has ever been.

It seems like every few years the High Priests of Science and their media fluffers have to break out a new "Einstein proved right yet again!" media campaign on the flimsiest of pretexts. The first such campaign was the May 29, 1919 solar eclipse that supposedly proved General Relativity but was, according to Nobel physicist Dr. Maurice Allais, a complete and total fraud. Now the establishment is reduced to proclaiming admittedly computer generated imagery as "direct proof" of the logically incoherent "Black Hole" speculation (see for instance Bill Gaede's amusing demolition of the concept. ) Where do the peddlers of this idiocy get the nerve to call themselves scientists? They are merely religious zealots who manufacture proof for their religion where there is none.

"
Stephen J. Crothers

"A telescope by definition is an optical device. It's for seeing things as they are seen optically with the visible light spectrum. A microscope is an inverted telescope.
A radio telescope is a misnomer. There are no optics and nothing can be seen without inferring radio wave forms into an image. By using the noise from 100^100 radio waveform recordings from 10's of spread out locations, the focus of the noise becomes so strong, that almost anything can be 'imaged' from it. An X, or a Y, or a Z, or a O.

Since the filtering algorithms were designed to filter out a hole, because the simulations were based on this assumption, that a hole is there, then eventually as they operate on the noise, they will create a hole. But in reality, there is no such thing.

The one aspect that is rather suspect about the mainstream models of black holes is that their mass estimates of the objects ares based on luminosity in X-rays without respect to the amount of electrical current present in the environment. That's undoubtedly causing the mainstream to overestimate the amount of mass that is present in such objects. "

It is amazing (and comforting) how this alleged black hole "image" is being derided all over the world. No one seems to buy it.

My favorite spoof of this "black hole" (currently circulating around the internets) is this :

Musing on science in general, electromagnetism, energy and why the Earth is located at the barycentre of our Solar system.

(Apologies for the format, language and spelling. Written in a hurry and I'm not a native english speaker)

Science is not what we think. Its been taken over by the Nutwork and turned upside down. Medicine is not about keeping people healthy, history is not about understanding our past, biology and physics is not about figuring out how the processes and mechanics of our physical world works. Todays science is about maintaining the dark age we're currently in.

And the way to accomplish this is by controlling of our monetary and information systems. If no one hears about the honest science and if doesn't get any funding, then it dies.

Propaganda and disinformation is key. The modus operandi can be seen and understood through 9/11. If someone like Simon Shack produces a movie (September Clues) that reveals how the 9/11 deception was carried out, it will be drowned in disinformation.

Electroscience was a big field within physics in the late 19th and early 20th century and our electrical systems is a result of research carried out more than hundred years ago. These systems are now controlled by the Nutwork, and they don't want any new discoveries in this field that can threaten this control. I haven't had time to look at communities like Thunderbolt or Electrical universe but I find it reasonable that they are just as crammed with Ace Bakers and Judy Woods as the 9/11 "truth" movement.

And of course Einstein and his Theology of Relativity is the granddaddy of Ace Bakers within physics.

Another side of energy is liquid fuels. Petrol now costs about two usd per litre in many Scandinavian countries. We have to pay the Nutwork hefty sums for a fuel that can be produced locally by renewable resources. When the car was first mass produced (the T-ford), it was designed to run on both petrol and alcohol. Most thought that alcohol would be the dominant fuel since it could easily be produced by farmers themselves to run their farming equipment. Set some of the crops aside, let it ferment in a silo, distill it and you have liquid fuel to run your machinery. But then came the prohibition era. Farmers were not allowed to make their own fuel in fear of public health(!), and the explosion engines was designed to run on petrol exclusively. Probably the usual problem, reaction, solution scheme. Alcohol posed a threat to the Nutworks oil monopoly so it needed to be stopped.

It's probably the case that most countries can be entirely self sufficient in terms of electricity and fuel production. Hydroelectric power is very efficient. Dams and water storages could be built to store water in ways that don't hurt wildlife and farming. Fuel could be produced by distilling crops or wood. The energy problem is perfectly solvable, but since the Nutwork don't want this to be solved they make sure the problem is not understood through their control of our information.

Over to electromagnetism and the shape of our Solar system.

Now to me it seems pretty clear that the force that keeps our planets spinning and orbiting is electromagnetic and this force behaves differently in a vacuum with zero kelvin as can be seen with whats called supra conduction.

Recently our Dear Simon Shack has showed us with his TYCHOS, that the only reasonable configuration of our Solar system is with an Earth located in its barycenter (that's slightly moving) and that the Sun orbits around us and that the the rest of the planets are in turn orbiting the Sun. Now this configuration can seem a bit peculiar. How come the Earth is a special planet? Why aren't we orbiting the Sun as the other planets?

I think the answer has to do with a theory called Stellar Metamorphosis. In this theory it is argued that stars, planets and moons are in fact the same type of objects but in different stages of their life cycle. A star becomes a planet that eventually becomes a moon. But I don't see any reason however why this process couldn't be slightly different. A gas giant could for example at some point light up and become a star. Perhaps this is the supernova phenomenon and Jupiter is the next planet to become a star?

Side note trivia: In 2010: Odyssey Two, by the Nutworker Arthur C Clarke, Jupiter turns into star that is named Lucifer... https://en.wikipedia.org/wiki/2010:_Odyssey_Two

So the reason that Earth-Moon is located in the barycenter of our Solar system could be because Earth-Moon system was the first binary star in this region a long time ago. And eventually because of the magnetic forces they expelled, a gas giant formed and lit up ouside of it - the Sun. And perhaps many years from now, our Sun will become a planet with Mars as it's moon with the star Jupiter circling around it. And on the Sun a new civilization emerges that cannot imagine that configuration to be correct. Just a thought :-)

All the best and may reason prevail. /Patrik

The term ‘black hole’ was coined, allegedly, after the ‘event’ of the ‘Black Hole of Calcutta’ in 1756, which seems to have been completely, and pertinently, a historical scam. (Incidentally, its main figure, J. Z. Holwell, a surgeon and an employee of the East India Company etc., was active as well in informing the British public about the - alleged - variolation practice in India.)
https://en.wikipedia.org/wiki/Black_Hole_of_Calcutta
According to Hong-Yee Chiu, a long-time astrophysicist at NASA, the Black Hole of Calcutta was the inspiration for the term black hole referring to regions of space-time resulting from the gravitational collapse of very heavy stars. He recalled hearing physicist Robert Dicke in the early 1960s compare such gravitationally collapsed objects to the infamous prison.
