How Our Galaxy's Supermassive Black Hole was Imaged 

🔴 Full breakdown of the original EHT image of M87* : ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-J2BHdrlUAOU.html

To LPA - I really appreciate your longer breakdown of the images. This is the most comprehensive explanation I have seen. Top tier content

Imagine being a photon that travels halfway across a galaxy and gets recognized by our technology and translated into images flourishing around the world. Crazy

I hope you get better soon. Back pain is no joke. There is so much to learn about these mysterious black holes. It would be nice to one day measure Hawking radiation.

Thank you for paraphrasing the “Dark Star” lyrics in your intro. It’s those kinds of references that make your shows so enjoyable!

Your explanations are, for some reason, much easier to comprehend and digest compared to other channels on RU-vid. Thank you for your videos, Christian.

The Event Horizon project is one of humanity's greatest achievements, absolutely nutterbutters.

Great presentation! I could actually follow the logic, though not the math, of the imaging process. Thank you, wishing you a quick recovery.

You've done it again Christian, made stuff thats complicated sound simple! Thank you, my head is now full of sparkling clover at the wonder of it. Hope the back gets better, I always 'lay me down' when mine is bad.

I thought I had seen all videos covering the recent black hole imaging, but this was MARVELOUSLY well put together. Almost too well - I had to take it back a few times cause you and/or your team absolutely nailed the graphics collection! Awesome, fascinating video. Thank you!

Excelent video. I like how you dig into the technical details, like showing all the different simulations, different imaging techniques, things that most science channels skip.

The donut on the Moon was an inspired aid in understanding the comparative sizes...

I have been waiting for you to cover a video about the Sag A*. so far the best and most informative video on youtube about it. Thank you soo muchhhh!!!!

That apple analogy was fantastic! Even though I know how we fill in informational gaps, that still caught me off guard.

Very excited to see more images (and hopefully animations) from the EHT!

Just another amazing thing - this might be the largest digital image (in terms of bytes) humanity has ever made so far.

Your explanations are the richest in terms of astrophysics. Thankyou to share your knowlege.

My observatory took part in the Event Horizon telescope observations that led to this! Never been more proud to have made the career change

Love watching your videos!

By far the best explanation about imaged black holes I found on RU-vid.

Outstanding vid and explanation...few channels go in depth like this one.

Your explanation is top notch, love your videos. Brilliant job, keep it up. Subscribed

What a great video! Thx so much

awesome thanks for another video! what a great way to start the weekend

this is so interesting! what an amazing breakdown!

The wait is over not only to see Sag-A star in all its glory, but also Christians take on it. "Very excited"

so proud of myself on finding this channel; bravo performance! thank you for sharing; Long live Black Holes!

Thank you for this video and your excellent explanations! You answered many of the questions I had when the image debuted.

I Always learn lots of thinks in this channel. Best of best explanation. Awesome work!

This was such a wonderful project. Big science at its best. Great video. Truly enjoyed it. Take care of your back my friend. It means everything.

Sorry to hear about your back and glad you are doing better. I agree that having some temporal distance between the news and the video is helpful.

Thanks, video was very informative..

I hope your back is feeling better Christian, I’m glad you’re back

Best explanation video that i ever saw! Congrats

Excellent explanation

Great video as always! Gonna keep some popcorn ready for the movie starring Sag A* :) Please get well soon!

Absolutely stunning explanation of complex math! Space technology uncovers things that will be common in the industry years to come. Please add more of these crazy tech explanations. Thank you!

Phenomenal video. So fascinating and so well done. 9:21 through 9:31 reminded me of Arrival. You're an excellent and highly effective teacher. I entered the video with enthusiastic novice knowledge and left it with, well not expert knowledge but certainly with a much more comprehensive understanding of several intersecting and interrelated concepts and topics. It's the same with your JWST video series which is absolutely top-shelf stuff. Thanks for what you're doing. Stunning video sir 🫡

Great explanation Christian.

If we just had more time we could observe and discover so much more. It’s amazing how much went into this and how long it takes to bring it all together.

I hope your recovery from your back pain will be speedy and well.

Great summary of one of the largest astronomy projects to date, all with help of a good old CD :)

CHRISTIAN!!! I hope your back heals well!! So basically, M87's black hole is sort of big, no problem. To be able to get that resolution is awesome, and given a few more years, I think it will improve. Thanks for another excellent video!!!!

If that change in orientation happened in the last few thousand years, maybe we could use Pulsar Timing Arrays to analyze the collision. Awesome video Christian! Feel better!

Always enjoy watching your videos, very informative. Waiting on July 12th for the images from JWST.

good luck with your back ! greeting from the netherlands !

Great video! How close to SagA* would one have to be to get the view the image shows?

Thank you for this thorough explanation of the image! I have 2 questions: Over what timeframe is the image "averaged"? Is it a few hours, or close to 24 hours, because of the rotation of the Earth? And what was the timeframe of that "best bet model" at 16:11 ? (How much time passes in 1 second of the animation?)

Extending these techniques to higher frequencies of light is the most exciting prospect for future astronomy, in my opinion. If the highest resolution ever seen can be attained with millimeter wavelength, imagine what can be attained with infrared and beyond

Thanks a lot. Get well soon.

may the force be with u

Back injuries are the worst!! I broke a couple ribs on my back beneath my right shoulder blade last winter and it took a solid 2 months to heal up.

The most outstanding video ever... Giving conceptual indepth and extraordinary information about sag A which no video in RU-vid has ever done yet...... Well a bad news is that JWST will send its first image on 12th july... This news is pretty much heartbreaking.. I was expecting that the first image will be fascinating us by mid june... But sadly 38 Days are left.... As long as I have seen your videos you have not discussed that how will JWST monitor blackholes or what extra information can JWST give us about blackholes... Is JWST nit designed for blackholes, neutron stars and pulsars? Sadly JWST is taking so long for its images... Why the calibration phase has so long duration... Which instruments are to be callibrated and how will JWST calliberate its instruments? ... What is that callibration procedure?

I hope your back is feeling better.

While it is hard to imagine the number of stars that must have gone into Sgr A*, I find it impossible to imaging how M87* could have evolved.

i have 5 herniated discs and one just herniated 3 weeks ago i feel you im trying chiropracter and phys therapy as well

Wow,Long Time No See,and I Feel You On Your Back,2 Major Lower Back Surgeries,and Hope Their The Last..A Few Of People In Our Astro Group Are Getting Jet Streams From M87 Sometimes,I Was Gonna Ask The Arc Sec Of The Moon,I Wasnt Sure,Wow,I Have A 2TB Flash Drive For My Astro Sometimes,Stack The Images In Deep Sky Stacker,lol..Great Video Christian,Hope Your Back Is Feeling Better Soon,Stay Safe,God Bless,and Clear Skies❤️🙏🏼🔭✨🌏

I think this is the first time we get to see a glimpse of something that is basically eternal, with M87. I don't think there's anything else that we've ever been able to look at where you can say I saw something that will still be here 10^100 years from now, amazing.

As per a recent study the synthesized image of Sgr A* may be wrong.Hope further study will clear the confusion.

Can Webb be use as well to help with this?

OUCH!...Hope your back heals up soon, having your back go out is the pits. P.S. Great vid, thanks.

One thing I'm curious about regarding these supermassive black holes and their glowing accretion disks. We know that in stars, in addition mere production of light, there's nuclear fusion going on. But is nuclear fusion also happening in the material around these black holes (outside the event horizon)?

Hope you’re doing well. Take care Chris!

19:41 I think its also interesting that we are in the right place in our galactic orbit for it to be face on and not edge on in the vertical orientation

Science has yet to figure out why there is a donut on the moon.

The black hole Sgr A* has now a Bengali name - 'Govir Mallika', given by the poets of Kolkata, India. The IAU has been informed about this new name. It's exciting.

Dark star crashes pouring its light into ashes

It’s okay. I feel your pain, literally. I just threw out my back today. It’s absolutely debilitating. Ouch. Better late than never.

Get well soon!

coooooooooooooooooooool

If it is pointing a pole at us... Um... Are we gonna get zapped the next time it has a big meal?

Don't rush your content

I for one caught those Grateful Dead lyrics to start.

I find it amazing that a spec of dust in the vast universe contains microbes that are observing and explaining stars, black holes and all kinds of cataclysmic events to themselves. A spec of the universe observing itself.

17:23 EHT goes to 11. Lol.

Black holes are very big beasts. Get well soon Christian. 😀🕳️

i didn't expect our galactic sink drain to be so weak

The worst thing you can do is to be sedentary and wear a back brace. You need to move and do back and hamstring stretches. I hope you feel better.

Why light itself can't travel at the speed of light .. what might be the reason?

Shall we go? You and I, while we can?

I wonder what JWST will see when pointed at this? I'm wondering if it's sensors might be overwhelmed in the infrared.

Jwst should have a look

👍👍💯

Don't black holes look the same from every direction?

Zero zero zero ZERO zero zero zero. New phenomena in YT.

0:06 sagittarius *a star* the supermassive *blackhole*

Can James Web telescope take picture of blackhole of our galaxy?

You need to find a legitimate chiropractor to fix your back. I have 14 years of experience. Finding a good one, that can fix you in one adjustment. You may not know it worked untill the next day. But, without your spine being placed back into it's original place... You will be exactly the same forever. I am a TBI survivor.

Nah I've been there and it's nothing like that... o7

For some reason people dont know that Einstein repeatedly said that singularities are not possible. Wherever you have an astronomical quantity of mass "dilation" (sometimes called gamma or y) will occur. Mass that is dilated is smeared through spacetime relative to an outside observer. General Relativity does not predict singularities when you factor in dilation. Einstein wrote about this in the 1939 journal "Annals of Mathematics". Nobody believed in black holes when he was alive for this reason. If you look at a common relativity graph with velocity on the horizontal line and dilation on the vertical line, the phenomenon is clear, even mass that exists at 75% light speed is partially dilated. There is no place in the universe where mass is more concentrated than at the center of a galaxy. 99.8% of the mass in our solar system is in the sun. 99.9% of the mass of an atom is in the nucleus. If these norms are true for galaxies than we can infer that there is 100's of trillions of solar masses at the center of common spiral galaxies. There is no way to know through observation, there is far too much interference, dilation and gravitational lensing. If we attribute a radius to these numbers, we can calculate that relativistic velocities exist in these regions, the same way we could calculate the surface velocity of the sun if you doubled its mass. The term "Black Hole" came about after Einstein passed. The term and the image was popularized by television and magazines and the belief in them gradually came to be despite the fact that there was no evidence and Einstein said they can not exist. If you pose the question "why cant we see light from the galactic center?" the modern answer would be because gravitational forces there are so strong that not even light can escape (even though the mass of the photon is zero). Einstein's answer would be because the mass there is partially or completely dilated relative to an Earth bound observer.

We need to move on from calling it a black hole and call it crystalline plasma because that actually makes more sense. Matter coming to the point where it goes from solid, to gas, to plasma, finally a higher 5th state where it's a solid plasma.

It's not a direct image of it. It's a reconstructed image.

now they need to image TON 618 😂

I'm pretty sure that picture of a black hole is not Sagittarius A Star...

Cool image but if it wasn't for some hardcore undergrads the whole research could become irreproducibile and there are even claims from Japanese scientist that the whole analysis is flawed and the resulting image is plain wrong.

Lol milky way’s supermassive black hole

it's not a "black hole"..
