Just Some Guy without a Mustache
Absolutely jaw dropping how inconceivably huge these supermassive black holes are. I always love it when Veritasium delves into the topic of space.

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.

It's important to mention that the "movie" of the stars orbiting our central black hole is time-lapse footage spanning nearly 20 years. I showed this to someone unfamiliar with astronomy and physics and the first thing they said is "the stars move that fast?!" - thinking that it was somehow real time footage.

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

That we have managed to aggregate instruments across the earth’s surface to achieve once impossible resolution is a real triumph for science, made possible by the use of GPS timing and location cues embedded in computer algorithms processing results gathered around the globe. Despite my understanding it, it’s a stunning accomplishment.

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!

More space please. This was absolutely amazing. Thanks.

This guy needs some kind of highest award for teaching humanity in such a easier way for us to understand

Took me a minute to distinguish when he’s referring to the event horizon or the Event Horizon™️.

I love how he explained it that even a person who has no understanding of this subject can clearly comprehend the process of creating an image of the black hole!
As a fellow teacher, I appreciate your style, communication, and enthusiasm. As a student, I appreciate the content, and ease of understanding it. You have found your calling!

I‘ve pretty much replaced Netflix with Veritasium. I mean, there are other great and very interesting channels in ITvid as well, but this one just takes the prize! Thanks Derek!

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

Every time I see explanations about space I'm incredibly humbled of my own existence.

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.

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!

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.
