I am in absolute awe of this thing. Every time I see that image I chock up a bit. I am looking at something that simply should not be viewable. I just have no words for this other than awestruck.

What really amazes me is the amount of predictive science, in interferometry and in cosmology, that made this image possible. It feels like a shot in the dark (with a ton of maths behind it) that we would be able to do this, and yet we endeavored. Yay SCIENCE!

Thank you so much! I was looking for an in depth report of what this image was :D

Thank you for giving us the legit science behind this.

"light from the magnetized plasma vortex is beamed on the side of the black hole moving towards us" is seriously the best description of this picture. It might be the most rad sentence ever uttered as well.

The main challenge in that case would probably be bringing back the information the telescopes recorded, because when they did all of their work on Earth, they had to bring physical drives containing the information because of the sheer size of the data. It wouldn't be particularly reliable to beam information back from the telescopes, so a solar-orbital telescope array is probably a bit further in our future. I imagine that perhaps a series of moon telescopes might be more attainable, simply for the fact that we've already proven that we can go there and get back

It could easily be said for any larger scale astronomy research, but the breakdown of how this was achieved is really impressive given the limited budget of the team. Interferometry is one of those tools that seems almost broken its so good, and I'm happy we manged to make a system at this scale. I very much hope we get to see more funding for projects like this.

Now that we have these algorithms already and we know they work, subsequent images will probably be released much sooner. The issue in space is going to be data transfer limits. On Earth we had to send all of the data by plane and boat because there was too much to transfer via the Internet. If we have telescopes orbiting the sun, we have no choice but to use wireless communication so it would likely take years to transmit the data back to Earth for processing.

@RizzsChannel

5 жыл бұрын

I'm not an expert, so take the following with a grain of salt, but if the baseline (distance between telescopes) is the one limiting factor for better resolution, we could probably do some simple math to figure out what ratio of resolution this photo would be in comparison to one formed from telescopes located at Lagrange points. The diameter of earth is 12,742km. This is the maximum baseline you can have for an earth-based telescope array. The two Lagrange points farthest from eachother are L2 (at a distance of 1.5m km from earth), and L3 (at an average distance of 299.2m km from earth), totaling about 300.7 million kilometers in baseline. Dividing this number by earths width and we get about 23600. So, according to this back-of-a-napkin, armchair expert calculation, we could achieve a resolution that is 23,600 times better than the photo we have now. Again, standard disclaimer, I may not have a clue what I'm talking about but it makes sense to me.

Regardless, if we assume a 10000x resolution increase, that replaces each pixel in The current image with a 100x100 image. Is that enough to get a picture similar to an "artist's rendition"? Separate note, I suggested a diet if JWSTs, but that observes in the wrong frequency, doesn't it? Would have to be a fleet of radio telescopes. Regarding that, how does the capability of each individual scope factor into inferometry?

Remember that he himself didn't believe that black holes could exist regardless of what his own theory (from Schwarrzschild solution) was telling him because he thought that there are mechanisms which will prevent the formation of the singularity and event horizon. I think he would've been overjoyed to be proven wrong.

I like how they're saying this is the first ever picture of a black hole, yet I know for a fact that in 1999, when I was 5 years old, I took a picture of the night sky with a disposable camera. That picture had to have billions of black holes in it, which objectively makes it a way better picture than what the EHT took.

​@@RoboBoddicker ​+eloniusz What you two aren't taking into account is the fact that the disposable camera I had used film, which is an analogue medium and does not use pixels - its resolution depends on the fine grain/molecular structure of whatever the film is made of. I haven't been able to find a number for the equivalent pixel resolution of film (perhaps because there isn't one), but someone ran the numbers on what the best available digital film scanners could do and got something in the gigapixel range, and that still wasn't fine enough to capture nearly all the detail the film captured. So, until someone can figure out exactly what the resolution limit is of film, I'm going to treat it as effectively infinite and say that 6 year old me was a black hole photographing genius.

Even if you had a magic camera with infinite resolution, no light from around a black hole would conceivably reach the sensor. You have a picture taken 'in the direction of black holes,' not a picture of black holes ;)

Bob Woodward In principle yes,technically no! :) To further simplifly the answer,the radio-astronomy is best suited for this technic... but as it name suggest it works only in radio spectrum i.e. mm,cm wavelenght. Exoplanets usually dont “radiate” in these spectrums(to keep it short),since they are not superdense hot plasma balls.And that leads me to the second part of your question since I suppose you have mean “surface feature on a rocky planet”?!? In which case you will need infrared to visible spectrum radio-interferometry... which in turn wont be the radio anymore and that technic became imposible from a technical standpoint.

Well, if my limited understanding is correct, light doesn't really "orbit". Space is so curved that if you go straight forward you end back where you started, no matter which direction you go. When this happens you are in a black hole. If there is a way out, you are outside.

Yes. If you had a powerful rocket with endless fuel, and hovered at the elevation that photons orbit, then 50% of your field of view (like the terrain horizon on Earth) is the black hole, and the other 50% of your view is the entire universe in all directions (all directions away from black hole, not just the one direction above your head). If you then whip out some binoculars at the photon sphere, you could look way out and see the back of your own head from the photons orbiting around.

Orbital mechanics and the conservation of angular momentum. Look up the orbital velocities and periods of the planets, you will see that Mercury is moving the fastest with the shortest orbital period. Just because of GR doesn't mean F= G(m1 x m2)/r^2 is completely useless and is often easier to think about in terms of angular momentum.

10 years? Hmm. You realise the sea level rise took roughly a century to go up one inche right? Yes the rate of change is expected to accelerate, but 10 years seems rather pessimistic. Besides if people were really worried and wanted to fix the issue rather than just be all high and mighty about how renewables will fix everything (they absolutely can't, not with current technology) then we would have been investing in nuclear power. Nuclear is the cleanest and safest of all power sources, including hydro and solar. It produces the least waste, is emission free, causes the least death and the least damage to the environment. Plus we can do it with complete safety these days, all the previous accidents were with technology that we would consider ancient by today's standards.

@@AndrewKimmey hmm China's population is stabilising while it's infrastructure is constantly improving, they also have massive amounts of water available in the highly populated parts so lm not sure what China's water issues are? Known resource reserves are more plentiful today than they have ever been in history and we continue to find more. The only recent resource conflicts have been around oil and yet there is vastly more oil available than the world needs at this point (one of the reasons so many oil producers like Venezuela have embargos against them), plus oil use will likely reduce a huge amount over the next decade as electric cars become far more widespread (purely economic reasons, not ecological). There has been some conflict over resources in Africa, but mainly internal conflicts and more to do with poor management than scarcity of resources. There is a looming issue of water or rather the damning and potential control of the water flow of the Nile in Ethiopia. The water isn't so much the issue as the regulation of the flow as Ethiopia wants to use the water for electricity production, Sudan wants the water controlled to avoid flood damage and Egypt wants the floods to fertilize their farms. Not so much a resource issue in their case as a management issue, certainly won't be an easy agreement to sort out. We won't run out of resources, as in any resources ever. We have been told that line since before l was born, but we have more than enough resources to last us until we simply mine asteroids and they are for our purposes essentially and endless supply. Our population would be a problem, except that as education improves, birth rates drop. So the expected maximum population is unlikely to go beyond 11-14 billion people ever, indeed it's likely to start falling. This is already a problem in most western countries as without immigration their populations would be decreasing as birth rates haven't been keeping up with the amount dying. Capitalism lead to the huge cities we have today, surprisingly this was a good thing for the environment as people that live in a built up city have a lower environmental footprint than a similar person in a rural setting. Essentially people that live in the forest, on farms and in small villages might be living among nature, but they have a bigger negative effect per person than people living in cities. Water was predicted to be an issue, but current desalination plants can produce water at an amazingly cheap price these days and if we use nuclear then water simply won't be an issue. Plus nuclear is classed as a sustainable fuel given we have enough fuel supply to last us longer that humans are likely to last. The human psyche in the west is definitely a valid issue, but it's really just history repeating. Hopefully it won't be quite as bloody as it often has in these situations. We are currently going through a transition phase, it happens with lots of things in nature, but effectively it comes down to things go too far one way, then they end up swinging the opposite. The west has swung so far towards the acceptance, inclusive political correct side that it is now swinging the other way. Most people don't agree with the overly liberal views often portrayed in the media or by very vocal activists on one side, most people also don't agree with the far right views on the other as most people tend to be somewhere in the middle. However the left leaning views have gone so far that things are starting to swing back to the right and unfortunately things will likely go far further to the right than most people want once the momentum takes hold. It's unfortunate but it's how many of the worst periods in history began and we could easily be heading in the same direction now. Still if the left were left to continue their extreme views(extreme in terms of pushing agendas far outside of what most people agree with) then western society would collapse anyway. The best we can hope for is something like the backlash to the over the top political correctness of the late 90's where we keep the better elements and get rid of the rediculous over the top stuff.
