RE: Black Hole eats sun (in reply to JasonM

At 9:00 AM Eastern Daylight time, tomorrow, Wednesday, April 10, scientists will hold simultaneous news conferences in Washington, DC, Belgium, Denmark, Chile, Japan, China, and Taiwan to reveal the long-awaited results of the Event Horizon Telescope. It will be very interesting to see the results.

It is things like this, the Event Horizon Telescope, as well as other like endeavors, that we should be spending our funds on. Trump's idea of returning to the moon is a waste of time, money and talent. We've done that and should be moving on to more intriguing things like Mars on the one hand and a greater understanding of quantum mechanics on the other.

Damn....I guess they are freaking real!







No Sagittarius A because she is not feeding like M87 was I guess, but he said they are working on it.
They said 7 years ago this thing wouldn’t look so photogenic, cuz it was spitting out blobs of plasma
back then, part of that massive jet stream.

RE: Black Hole eats sun (in reply to BarkellWH

I watched the whole press conference. Fascinating stuff. This is probably one of the biggest scientific accomplishments in my lifetime. Truly amazing what we can achieve when all borders are removed and scientists work together across the globe.

I love that one of the first questions from the press was that it looks kind of fuzzy and if can they sharpen it lol come on

RE: Black Hole eats sun (in reply to Ricardo

Great posting the photos, Ricardo. What a testament to man's intellectual and technical ability to begin to really understand the universe, both at the macro level (cosmology) and the micro level (quantum mechanics). This is one big step among many, but it is huge.

Below are a couple of quotes from the website ARS Technica.

"At a press conference this morning, Avery Broderick of the Perimeter Institute described what the images tell us. One key finding is that the object is a black hole, at least as we've understood black holes using relativity. It does not have any visible surface, and the "shadow" of light it creates is circular within the limits of our observations. We can also tell that it spins clockwise. All of the properties we can infer from these images are consistent with relativity. "I was a little stunned that it matched the predictions we made so well," said Broderick.

"The University of Amsterdam's Sera Markoff said that the size of the black hole provided a new estimate of its mass; she called it "really a monster, even by black hole standards." It's roughly the size of the Solar System, but has a mass that's 6.5 billion times that of our Sun. This actually resolved a conflict between two other measures of its mass, one from the motion of gas clouds nearby, the other from tracking the stars orbiting it. This may help us refine estimates of mass for black holes elsewhere."

Great stuff.

Bill

Behold the great eye of Sauron!

The guy also said something like the view of Sagittarius A is always shifting making it hard to image.

RE: Black Hole eats sun (in reply to BarkellWH

What kind of timeline would be presented with the emulated movements in the first .gif?
-

In another forum someone said hopefully this would contribute to (perceived) shrinking of the problems on earth, to which I posted an excerpt from a dialog with a fictive AI-consciousness. -Named Olga, that I mentioned here before.
(Whichs content again, I suppose no one here would like to ponder about.)

Another poster said how fascinating it was to see what can be gained when international scientifical means are bundled up.

To which me fully agrees.
May such swiftly come about for imminently relevant matters on this tiny planet, 55 mill. light years off the scene.

RE: Black Hole eats sun (in reply to Ricardo

Thanks for the pictures. Truly amazing. I'm both excited and kind of terrified that these things are actually out there...

Today, we also had an announcement on the discovery (or confirmation rather) of a new branch in our family tree: homo luzonensis
https://www.nature.com/articles/s41586-019-1067-9

That's a lot to take in for one day!

PS: reading up on it, it seems that the first "accurate" visual representation of a black hole (horizon event, you know what I mean!) goes back to the work of Jean-Pierre Luminet (published in La Recherche and Astronomy and Astrophysics in 1979) using a punch-card IBM 7040 (see last page):
http://adsabs.harvard.edu/full/1979A%26A....75..228L
40 years later and we finally have the real thing!

One of those rare days where science fiction becomes science fact.
