What...??

You cant take a photo of a black hole itself, obviously. You can capture an image of its surrounding accretion disk, which that photo seems to do. But... that’s already been done before, no? Accretion disks have been observed around black holes before. Theyre what has given the most credence to their existence heretofore.



The research was conducted by the Event Horizon Telescope (EHT) project, an international collaboration begun in 2012 to try to directly observe the immediate environment of a black hole using a global network of Earth-based telescopes. The announcement was made in simultaneous news conferences in Washington, Brussels, Santiago, Shanghai, Taipei and Tokyo.


This kinda feels like a press release justification for a long and expensive project.

Looked thru the article to find out how this is “different” but Im not seeing it. If someone can shed some light, it would be appreciated.

So let me ask a dumb question. How did astronomers know black holes existed if this is the first time one's been captured on film?

Einstein's theory of relativity put down the basis for the existence of black holes although he himself disliked the idea - his equations showed that once a star dies if the mass remaining is 3 times that of the sun its gravitational force is enough to pull everything into itself and form a black hole.

They were found out 60 years later after rockets equipped with Geiger counters were sent to a double-star system and scientists observed x-ray radiation that they interpreted was caused by a black hole - if a star is too close to a black hole it gets sucked into it and as it throttles towards the point of no return it emits x-rays.

You don't have to see something to know it's there.

The rest is simple calculations, such as Kepler's law to determine the mass, but not simple enough for a comment section.

How can you determine the composition of the atmosphere of say Pluto if we never landed there? Sounds complicated, but it's all very basic stuff, but first a person needs certain understanding of certain things.

Guess no one wants to take a stab at this?

Looks like Sauron to me.

These scientists are sitting in Isengard trying to communicate with the Dark Lord

Fatrick you should close your legs your puzzy is sucking up all of the light you inconsiderate ****

[scuzzy]

wish they made more movies like Interstellar with modern CGI


seems like all the well thought out space travel films or ones based from novels were in the 70's-90's and held back by old production

This is a picture of the event horizon. And it took an equivalent of a Earth's size type of telescope. Something like 27 petabyte of data, and a super computer analyzing and putting all the data together. It's not an image of its accretion disks.


We've never had an optical image of an accretion disk with enough resolution to distinguish it from the black it theoretically surrounds. It's nice to have as further evidence for black holes.

The biggest piece of evidence is probably what jstern referenced. It is an animation based on the calculations of star trajectories around a tremendous amount of mass within a very small volume of space. Nothing other than a black hole is expected to exist in such a location. There are other pieces of evidence as well like quasars, GRBs, and long particle jets.

Just to make everything clear, it's not an animation based on any calculations, but rather actual stars orbiting Sagittarius A, with the month and year in which the pictures were taken on the top right. The stars are highlighted though.

Mind-bending stuff. So he essentially theorized the existence of a black hole before its eventual discovery??

An event horizon is a conceptual demarcation between two regions (inside the black hole and outside the black hole, in this case). It is not an observable physical thing.

That is a picture of an accretion disk.

Yes, which is why guys like Einstein and Newton are held in such high regard.

Ya. I didn't mean to imply that. They took actual pictures of stars over the course of several years and mapped the trajectories on a 3D plot. From there they deduced an enormous gravity source in a very small region of space. The EM observations from the region are also consistent with that of a black hole.

All the nonsense this society focuses on when the universe is so grand and incredible. What a joke.

I love this astronomy stuff.

anyways, awesome photo.

So black is not a color, but the absence of color?

Therefore, no one has seen the color black, because it does not exist. :lol



You straight up clown yourself in your own posts.

Saves me a lot of time. I appreciate that.

[Akrazotile]

God dammit, let me take the long way on your stupid ass.


A black circle in a picture isnt a black hole. You are not SEEING an image of a black hole the way youre visibly seeing the burning matter/gas surrounding it.

Youre seeing a void. A void could be anything. I could take any number of pictures of an empty black space somewhere. That doesnt mean it’s a black hole inside.

This picture of an accretion disk is EVIDENCE of a black hole, it is not photo PROOF of a black hole.

If I take a picture of a giant cave, or a giant footprint, does that equate to a picture of bigfoot?

Do you understand, pleb??

Okra, were you home schooled?

Not sure why you'd work yourself up so much over semantics, but knock yourself out.

Especially when you struggle with science so much.

Hey bro, why don't you explain to us why the moon landing was such a total waste of resources again.

[Akrazotile]

Nah bro. Sounds like you were tho, yeah?

Uh, no. You asserted a serious premise. Unless you think black ISNT the absence of color?

Then in your very next sentence tried to discredit my post by asserting the opposite of the premise you just stated.

Youre trying INCREDIBLY hard to save face.

You are a TRY. HARD.

You TRY to act knowledgable about all the fancy book learnin under the sun, when you arent. Stop always trying to punch above your intellectual weight. Youre a simple fool who will never be seen as a serious intellect.

Stop talking about color until you understand color theory. :lol Here's your first lesson.

If you have two colors, how do you tell how close in color they are mathematically? If you know what "a" and "b" are. What other variable is needed?

[Akrazotile]

How do you reconcile the fact that you think you’re really intelligent yet you’re completely broke and haven’t done anything meaningful in your life?

Is it hard to keep lying to yourself so consistently?


How do you reconcile the fact that youre arguably the least interesting poster on the board and that’s why I never address you, and every interaction we have is you provoking some kind of communication from me like a lonely woman pulling on the arm of her boyfriend who’s busy doing something else?

Hm?

Get this thru your head:

IM NOT YOUR BOYFRIEND. Go tease someone else.

[BarberSchool]

The fact we haven't yet found compound galaxies,
sharing outer orbits,
in an effort to become inert ...

...worries me.
Lends credibility to the idea that the vastness of space is indeed too great for us to make meaningful contact in our short @ss lifetimes.

Makes sense since mankind is still in it's infancy, floating in a desolate empty corner.

Far away from all the beautiful compound galaxy beings.

Or something like that. And stuff.

The craziest thing is the distance of this black hole from Earth and how we still were miraculously able to take a picture of it.

If my math is correct, one light year = 5.9 trillion miles. And this black hole was 55 million light years away from Earth. :eek:

space & the deep sea. fascinating stuff.

[GimmeThat]

essentially we're still stuck on the theory of fire

if space travel indeed does require being in a state of 'uninhabitable' the cause of Earth spinning on its own, which we contribute with the term rotation instead of orbit might provide us with some insight, particularly regarding the north and south pole

interestingly enough, the electroweak force would require the temperature to be near level that hadn't been achieved since shortly after the big bang, while we would need sustainable energy in space in order to travel at a speed faster than the current technology display

I suppose in common language, I wonder what effects weak forces can be connected with the voltage of electricity

Yeah, and to imagine that as deep as the ocean is to us, if you compare our ocean to just our own galaxy, its like our ocean is a drop of water to every body of water on earth :eek:
