Capturing the photon ring of a black hole

- A team of researchers led by astrophysicist Avery Broderick used sophisticated imaging algorithms to essentially “remaster” the Event Horizon Telescope's 2019 image of the supermassive black hole at the centre of the M87 galaxy.
Simulations predicted that, hidden behind the glare of the diffuse orange glow of the 2019 image, there should be a thin, bright ring of light created by photons flung around the back of the black hole by its intense gravity.
“We turned off the searchlight to see the fireflies,” explains Broderick, an associate faculty member at Perimeter Institute and the University of Waterloo. “We have been able to do something profound - to resolve a fundamental signature of gravity around a black hole.”

The animation really helped to get a grasp of what is goin on! Thank you so much for this channel❤️
Flat earthers rush in in 3… 2…
Dood, what the fuck are you talking about?
Thanks for sharing this information
Amazing. Also terrifying.
Wonderful science.
Since an event horizon is timeless, and photons don't experience time, is it safe to say that black holes are comprised of photons or other timeless particles, and not massive particles at all?
An EH is not "timeless" so the answer is "no" - you could go to an EH, you & your clock will tick away just as normal. A clock at the EH will appear to run slower from the point of view of an observer much further away. With a sufficiently large BH you'll not notice the moment you pass inside the EH.
2:35 What does „As seen by the event horizon telescope“ , „simulation“ and „observation“ mean?
I thought the images from the ETH are an observation?

Wonderful ~ ! 💝 💯 👏 🎉 🙏 🚀 👍 🤖 🎅 ✝ 🌝 !
They used the Photoshop sharpen algorithm.
Too much math and a good simulation and people will believe whether it is true or not.
Too much mathematics…? And then we will believe if it is true or not? That is how you come to not only believe, but to understand it. With theory, and then with observation. Belief has nothing to do with it.
@@rowangi There are many things Math will never give mankind. Common sense, I think is the first.
@@martinsoos "common sense" has no place in evidence
@@mudkip_btw The lack of wisdom suggests that you are a very knowledgeable person.
Capturing my as
All BS.
That's not a ( so-called ) "Black Hole", because there are none in the whole Universe.
Do you have a learning delay?
So what’s your expertise on this matter?
@@rowangi he has a phd in flat earth
@@kkkk-ud9ll I thought as much…
Wellu R / A very good one, specifically:
1) I have learned the true dynamic of the Universe; therefore, now I know how everything works correctly in the Universe.
2) I use all the time my own brain. /
Idiots think always with the brain of other idiots, repeating the unbelievable stupidities that are in many ( so-called ) "scientific theories".
Some of those idiotic and completely erroneous theories are, for example, einstein's relativity, quantum theory ( of my as ), and so on.
By blindly believing those idiotic ideas you'll never be able to understand correctly the true dynamic of the Universe.
