  1. The continuous zoom-in from a relatively wide view of the night sky all the way to the stars surrounding the black hole really puts things into perspective.

  2.  @janbernad4729  Making things useful to someone one out of ten days isn't a very accurate description of how science and scientific work benefits people. It's more like making a useful thing once or twice in a lifetime that will be useful for millions of people in the future. And the only reason why we have modern medicine for Doctors (who themselves also conduct scientific research and have acted as a scientist at some point in their schooling), or advanced materials for Engineers, and electronic products for workers, is because of scientists. It's a very simpleton way of thinking that others are providing for him.

  3. The misunderstanding comes from the myth that glass flows slowly over hundreds of years making old glass panes thicker at the bottom. Obviously glass looks like a solid, that's why the myth that glass is a liquid is so intriguing, because it is unexpected. It's pretty easy to understand why people would believe the myth, because it would be hard to test and disprove that glass doesn't flow over hundreds of years.

  4. true, though considering how few negative results get published, on that graphic it would only account for about one checkmark or maybe not even.

  5.  @Byggherren  This is why it's annoying seeing some top comments be "it doesn't sound that way to me, so why watch the video". The point of the video is to actually teach you about hearing, not boast about whether an auditory illusion works on you or not. Their loss I guess.

  6.  @bishrarar3015  Well of course, engineering courses take months. This is a 26 minute video. Getting a grasp is often the most important part because it provides motivation to dig deeper.

  7.  @newstartt99  The chess example is very short sighted. Chess is a game with direct competition, the opponent can only be your competition and there is no incentive to cooperative. But in real life, there is virtually no situation like this other than in games themselves (like sports). Even in a situation where someone attacks you, cooperation (ex convince them to stop and they agree) is a viable option. The video is just interesting evidence of the theory matching the reality. It's pretty obvious to any civil person that cooperating more than betraying in your daily life will lead to good outcomes.

  8. True, videos like these have such value for visualization even for people already deep their STEM fields. This is why it's sad there was that whole movement done by internet elitists to try and make Veritasium out to be a fraud because of that one electricity video that caused confusion. Mob mentality really sucks.

  9. My hope is that this video leads curious people and bridges them over to channels like PBS spacetime that dive deeper into these subjects.

  10.  @tafdiz  That's why he said all people involved. Regardless of how big the team is or how it was produced, we can all appreciate great educational content.

  11.  @SleepyfrNgl.0 the difference is people care about Nakamura, no one cares about you

  12. Honestly, it's probably easier to find useful applications for this compared to a lot of areas of science. And given enough time, humans usually find many applications for even the most unassuming discoveries. Understanding crystal formation seems rather useful to me, and that's not even taking into account the artistic side of things.

  13. ​ @trout3685  wholeheartedly disagree. The video is presenting educational information. Whether you forget the next day or not depends on whether you treat it as education or entertainment when watching. Same thing applies to school. If you don't make an effort to remember things, then you will forget it. That doesn't mean it wasn't education.

  14. This is why Healthcare should not be private.

  15. Yeah I mean if you look for a real video on the immune system, it is mind bogglingly complex. Hundreds of different types of cells, all with unique jobs and traits and number in the billions.

  16.  @swaggery  Of course, people did put in the effort. But since the inception of the concept of black holes, it's very obvious they would be difficult to observe considering their size and "blackness".

  17. Yeah I was surprised too. But it makes sense, Andromeda is only 10 times as far away as it is wide. It's just that most of it is too dim to see with the naked eye. Exposed photos can capture how large it really is.

  18.  @origamipostit  he's referring to the people almost 100 years ago. Of course, now they have been observed.

  19.  @mosubekore78  What an odd assumption. It's a decades old problem which had larger companies stumped, the earlier management understood that R&D would take time. Tbh, the newer management did too, but wanted to control his direction in research despite not being scientists. None of the actors in this story were dumb enough to cut R&D budget because they knew the rewards of a potential breakthrough. I don't think it's arrogant of him to believe that he knew which direction of research was more promising compared to a son-in-law executive.

  20. One of the big ones is just that it's pretty expensive

  21. light travels about 300,000,000 m/s btw. In other words, 300,000 km/s. So the star travels at 24,000 km/s which is slower than light.

  22.  @mr.bladez1131  if you care about poverty, worry about the funnelling of orders of magnitude more money into the stagnant accounts of billionaires rather than publicly funded scientific research lmao.

  23. The video did a great job presenting and building up to that moment showing Nakamura with the blue LED in hand. That moment hit me.

  24. They did show many many images of the black hole, and it didn't show the same pattern. There's probably too much volatility to explain one particular image.

  25.  @KeyleeMai  I mean he didn't write that particular paper. The fact that human pride puts so much value on name order that you burn all bridges is the real folly. The fact that he went on tour as a celebrity rather than continue any scientific work shows how important the science was to him. He didn't care about any of them before he left either.

  26. The point you are forgetting is time. (V1+V2)/2 does not equal Vavg because the time spent at V1 is not equal to the time spent on V2. It's the distance that is equal however. If you complete the 2 laps at 2V1 speed, it would take the same amount of time as 1 lap at V1. Therefore, you must complete the second lap in zero time at infinite speed because of how slow you took the first lap.

  27. Coming back to this video, I'm still impressed. This was the first time I was given an logical explanation that changed my assumption that the universe is deterministic.

  28.  @Ubersicht True, on the other hand, I'm very grateful that these videos are available to the wider public and draw so much traffic and interest. These are the type of results that make me feel promise for the next generation.

  29.  @laserbeamchaser  true, it's a good exercise for everyone to do tbh.

  30. nah it's just the wealth gap

  31. I'm guessing it's a high school physics teacher. It's not surprising, my physics teacher also didn't believe me about the accelerating expansion of the universe. I guess he has a hard time believing discoveries that go against common rhetoric at the time when he went to university.

  32. This is a great example of why all science is valuable even if it appears useless at the time it was discovered or created. You have so many people nowadays complaining about certain fields and projects being useless, it's frustratingly shortsighted. You never know what will end up being groundbreaking in the future.

  33. The thing is the species that was once cavemen was able to build jets. Cavemen attempting to explain the world around them eventually led to the technology we have now. There's no point in scientific defeatism even if it's likely that most of what we understand today is not correct. It's all part of the process that most things will be proven wrong in time. It doesn't mean the steps in between are pointless, it's all necessary in achieving a better understanding. If no one takes the first steps however wrong it may be, progress will stagnate and nothing would ever be done. If you want to look down on it and conflate it to "guessing and shaking our heads" go ahead, but it sounds like you are already defeated by the uncertainty of it all.

  34.  @chrisprilloisebola there's competition but rarely zero sum games in real life. If people approached life as a zero sum game, we wouldn't have society. Sophisticated human cooperation is the only reason we aren't living like cavemen. Look how as every aspect of society is predicated on growth, if it was zero sum, there wouldn't be growth. Individuals can sometimes benefit by being uncooperatively selfish, but in a macro scale, such a philosophy would never work. The lesson is don't fall for that edgelord crap and just live like a decent person.

  35.  @chrisprilloisebola  Of course it's not how it always works, but it is a good philosophy to live life by. The daily lives of people in developing countries isn't that of deceit and betrayal. It's mostly decent people living decent lives, but being exploited by structures of power. But it's not a regular citizen has any say in that. All anyone is saying is that in real life cooperation is how people get by in life,not that you should always do it no matter what. That should be obvious. And pedantically arguing in favor of being uncooperative? I find that to be the type of edge lord cynicism you see a lot these days.

  36. I knew the Hilbert hotel video must be just a setup video to something big. Great video.

  37. I had no idea Andromeda spanned that much of the sky from Earth. I know it would require a lot of exposure to see it fully, but very cool.

  38. If we thought like this, we would never advance in science. Imagine the people saying this of Galileo in his time, that his life's work was pointless; studying stars and planets we could never reach. There were those people of course and they were wrong.

  39. Remember this is essentially an earth sized array forming a composite image. GTC's size will not do.

  40. Sure thing. The equation (V1 + V2)/2 = Vavg is flawed because this only works if the time spent travelling at V1 is the same as V2. However, it's actually the distance traveled at V1 and V2 that is the same. Since you need to average 2*V1 speed over two laps, going at 2*V1 speed would take the same amount of time as travelling 1 lap at V1 speed. So once you complete the first lap at V1 , you have zero time to complete the second lap to get up to 2*V1 average speed.

  41.  @qrowing  Yeah but that's what happens when creators try something different and out of their comfort zone. Sometimes it works, sometimes it sucks lol.

  42. Yeah some other countries might do that, but US and Canada definitely don't have that in the 8th grade curriculum.

  43. I wouldn't say that's what happened or even that he changed his mind. He just admitted his belief is just a feeling. And no one knows what the future advances will be to favor one argument or the other

  45. A full planet to discover, but under the feudal system, no one was discovering anything. If we're talking about making discoveries, dark and middle ages, is about toxic an environment as it can get.

  46.  @beyondwhatisknown  I agree that gifted programs are not great and pretty pointless, but saying they "may have been created to decrease the ability of intelligent people to reach their potential" is just a textbook conspiracy nut way of thinking that's been trending up worrying recently. Not everyone is working against you with a grand agenda.

  48. He does periodically drop this type of video. The channel is diversified with a few video format like on-site interview tours, but these videos are the real gems.

  49.  @forasago  The video isn't just about that particular illusion. It's about a range of audio phenomena. It's educational. For the colorblind example, I'm don't have it, but educational videos about it are interesting. You don't have to relate to it to find it interesting.

  50.  @sciptick  This problem with this type of attitude is you get too comfortable and focused with what you know, when the real problems are what we don't know. I wouldn't say 'they don't tell you'. The video is about the development of the first usable blue LED and is of suitable length. Info about innovations since would take more time and isn't naturally in the scope of the video.
