Absolutely jaw dropping how inconceivably huge these supermassive black holes are. I always love it when Veritasium delves into the topic of space.

The way you describe the 'Earth sized" telescope at 10 minutes was so perfect.

The world needs teachers like him! Watched many videos about Sgr A* imaging and none of them explained it as clearly and simple as he did! I am marking this video as my black hole reference.

universe is so crazy to grasp, at one time you get the feeling of existential crisis on the another instance you want to fly in the space and see what all is happening in the space, sometimes you feel if you had the superpower to go back in time that would have been great...

This was so rewarding to watch and fascinating to learn how far we’ve come in proving black holes exist. In my college astronomy texts from just two decades ago it was all still considered just theoretical. Thanks Veritasium!

Your dedication and interest to make us understand the concepts are extremely adorable. This is the best explanation I have ever seen on the internet.

More space please. This was absolutely amazing. Thanks.

Thanks Derek! But it still remains unclear to me: if the accretion disk can be directed towards us, then why can't we see its leading edge crossing the central region of the image? After all, some of the rays from it are not directed in orbit around the black hole, but directly towards us, and, in theory, should not change their trajectory (well, or almost).

Hello Derek, I applaud as excitedly as I can what you do; thrilled my pre-teen children look forward to each of your videos and deeply satisfied and comforted when they walk away fascinated and excited how they learned a fundamental and complex concept that might have otherwise been too difficult to grasp. I feel less disappointed as a father bent on staying in "scientist" mode that you and the videos you deliver exist! You have my eternal gratitude and my undying support!

This is mind bending. Your explanation is so easy to grasp given the complexity of the subject matter. Now I have some level of understanding when I look at the image. Thanks! 😁

The fact that I could understand everything you said, speaks volumes about your ability to teach. Thank you for making me feel smarter than I actually am!

Man, thank you for making these videos. I’ve been obsessed with astronomy and Astro physics my entire life but you somehow have a way of explaining things that helps me to understand better than ever. I’ve thought about that image of a black hole from interstellar for years now trying to figure out why it looked the way it did. I knew it had a lot to do with the mass and warping of space time but this video is so informative. Thanks again for the great content.

This is hands down the best explanation of a black hole I've ever heard.

The best part of this video is that Derek looks extremely happy and excited when he explains the image with his cardboard model... This is why I love people like Derek Muller, Physics Girl, Michael Stevens - they are just soooo happy and enthusiastic to teach us such complicated topics in a simple yet profound manner. To me, people like these are not in anyway inferior to those who look up at the sky and solve the mysteries of the Universe.

Thank you for explaining how the image was obtained. I love learning about the science and techniques used to arrive at a discovery, or in this case, in getting an image of something so incredibly far away.

Thank you so much for the visualisations. Even though I am interested in astrophysics for decades, I found few explanations which show in a simple yet accurate way how astrophysics actually work.

Idk, there’s something hunting and beautiful about the finality of the theoretical existence of an object as mind bending as a black hole; let alone a supermassive black hole in our own backyard. It’s as awesome as it is frightening.

The craziest thing to me is that these images just confirm our theories. We had visuals of black holes purely based on the Maths. A random guy on the street could have a decent image of a black hole because a movie did the effort to represent it correctly (minus the lighter and darker parts). And only a few years later, we manage to take a picture which just happens to be exactly what we expected.

This is the most understandable explanation I have seen of the operation of a radio interferometer. The graphics are very clear and awesome. Thank you so much!
