  1. Can't wait for a day when, "I rented a blackhole to settle a physics debate"

  2. I don't know if you can afford it, But this video needs a revisit. Ideally with more effort put into the rods than the sand buildings.

  3.  @noobofnoob3591  Indian system is bad not in terms of money, But how it gives very little credit to the creativity and talent of students and its notorious for shoving unnecessary subject down students throat. I think anyone who spent significant time in any Indian education systems (with some exceptions) would know that the only thing matters in there is how well you can remember stuff, It doesn't matter if you actually understand it. Don't even get me started on quotas, The dumbest thing in Indian education system.

  4. Just goes to show how out of touch our education system is.

  5. I don't think it gets said enough, whoever does your animations is simply amazing, They can convey even the most complex of ideas with simplicity and ease that even someone with no background in that relevant field can understand them.

  6. While you explain some highly complex problems in simple and elegant way that even someone not involved in the subject can understand them, I do have to give a BIG kudos to your animators, the animations literally act as bridge between my intuition and your explanation!

  7.  @noobofnoob3591  Thats my point tho, Having a few reputable universities doesn't help when the very fundamental organizations such as schools/high schools don't encourage skills and talents, Instead they just force students to learn things they don't want to and focus on how good the students are at cracking the exams rather worrying about whether they actually learn something or not, So when students complete school they feel more confused about going forward. If we ever want to compete with developed countries in terms of education, We would have to throw away our old rusty system and build a new one from ground up which is in line with the modern world.

  8. The segue into the multiverse theory is why I love this channel.

  10.  @kirbwarriork3371  Yep it seems like a lot of information is left out just to create a clash between two different answers to two different questions.

  13. What an amazing explainer Dr. Shaw is. I love how he got excited when Derek mentioned he brought a special lense!

  14. I have heard of the idea of white holes but the way this video built up to the theory of white holes was truly mind blowing. It felt weird because I have no physics background but thanks to the great narration and visuals, things made sense!

  15. Yep our education system is old and out of touch with the modern world. It only lives to suffocate students and kill creativity.

  16. Exactly! They're fundamentally different because the latter ties the sleeping beauty being awake to the probability of the coin toss while the former doesn't. I am genuinely confused about what the point of this video is.

  17. The blackhole still looks more clear than CCTV footage on Earth.

  18. Correct me if I am wrong but why can't we have two clocks at a distance, a button that sets them both to zero. Once they're both set to zero, we fire the light, as soon as light touches the clock 1 it starts ticking and same for the clock 2. Now measure the difference between the elapsed on both clocks and that should tell 1 way speed of light?

  24. I used to hate math as a kid, but its channels like this that make me wanna start learning it again.

  25. Why did Leo Szilard cross the street? To make an atomic bomb. I'll see myself out

  26. This genuinely makes me wonder, is this a failure of an education system or do these people just don't care about knowledge.
    2
  27. Only goes to show what India is missing out on, Our education system is in desperate need of an overhaul.

  28. Yeah feels like a meaningless video, but I did like the segue into the multiverse theory.

  29. Interesting idea! In theory yes they would be at rest relative to each other but like you mentioned its not known if the expansion of the universe would affect at this scale.

  30. For being a Veritasium video I am surprised how little thought was put into it.

  41. ​ @_Ciosu..  Its not considered a planet like Earth or Mars anymore.
    1
  42.  @_Ciosu..  Pluto is classified as a "Dwarf planet" meaning its planet-like but its gravity is not strong enough to dominate its own orbit. It is explained pretty well in the video itself. I just gave Earth and Mars as examples. Scientifically there are 8 planets in our solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.

  43. I don't understand why are we fighting over two different questions altogether.
    1
  44. Really pointless video because it really depends on what question is asked, if subject is not given any information including the fact that their waking up depends on the results of coin toss then the logical answer is 1/2, if it does know that its related then the answer is 1/3
    1
  45.  @atharvbhandari994  Yes but the video is made in a way that makes it seem like 1/2 and 1/3 are both correct answers and its some kind of a paradox.

  46. I find it hard to believe that nations would just happily dismantle their nuclear arsenal worth billions. Instead, they just keep it off the books to avoid controversy. If they can cover up nuclear accidents with the "classified" excuse, how hard is it to hide nuclear weapons.

  47. What are the chances that what we call the Big Bang is actually the origin of a whitehole. It fits the mathematical description perfectly.

  52. Yes a lightyear is a distance that light would travel in a year. So it can be thought of as both distance or duration.

  53. ​ @lequedicatsamarge4228 ​ Because knowledge is passed down the generations it is important that you pass down the correct knowledge. It is considered "basic" knowledge because its all around us and its easy to learn. Sure knowing that stars are bigger than the moon may not change your life but it shows that you have good understanding of facts which crucial for scientific discovery.

  54. This immediately made me remember Mehdi's (ElectroBOOM) Right hand rule dance 😂

  55. They're actually likes and dislikes from the video updating automatically. 1/3 means like, 1/2 means dislike

  56. My biggest disappointment is not the lack of knowledge about space but the amount of people that think astrology and astronomy are interchangeable.

  57. To answer "What is the probability that it came up heads?" The objective outcome of a fair coin toss will always be 1/2. She will always be woken up on a Monday regardless of the toss result, but she will be only woken up on 50% of Tuesdays. Thus 1/2. Now if you wake her up and ask "Given you're awake, what is the probability that the last toss result was a heads?" To this the answer is 1/3 assuming the sleeping beauty knows when she'll be woken up, but the video doesn't really mention anywhere if she knows on what conditions she will be woken up.

  60. Aaaaaaand he changed the title.

  61. Is this an April Fools
    1
  62. This can be solved simply if the question is worded better? "What is the probability that the coin toss was heads?" Answer: 1/2 "What is the probability that the coin toss that woke you up was a heads?" Answer: 1/3 It really boils down to what context you ask and answer the question in.

  63. It should be easier to run a simulation using something like Python
    1
  64. Thinking the same thing. If both clocks are at 0 and only start ticking when light hits them then why do we need to worry about synchronisation? Just subtraction the time of clock 2 from clock 1, no?
    1
  65. Exactly my first thought! But only such object that exists is a blackhole so its hard to verify.

  66. Agree this thing would also help you stay out of jail

  67. Imagine cutting the shapes out of the question paper during the exam to find the right answer.

  68. I don't see how this is related to recursion

  69. I just realised the title of the video changes based on the likes and dislikes!

  70. Read a lot of news articles about this and they were pretty meh, but Derek here explained what we see and why we see it in such simple terms even a kid can understand!

  71. I have watched so much space content on YouTube that the question at first seemed like a trick question.
    1
  72. Bingo! The answer changes depending on how the question is worded.

  73. I want more of those videos where you would go out and ask people the most basic questions that they take for granted, Then proceed to blow their minds. The best one was "Where Does The Sun Get Its Energy?" As for my all time favorite, It will always be the explanation of the first ever image of a blackhole, The way you explain things is just amazing.

  74. I am gonna watch CoolWorlds FTL video now because the space time diagrams actually make sense to me after this video. 😅

  75. Exactly, I feel like he is intentionally trying to confuse the viewers when he himself said at the start that it depends on what questions you ask. If you ask her "what is probability that the result of the coin toss that woke you up was a heads" answer should be 1/3 If you ask her "what is the probability that the coin toss was a heads" answer should be 1/2 Her waking up more than once after the same toss result isn't tied to the probability of the toss.

  76.  @shade0636  The first question puts the sleeping beauty in the context and assumes that she knows on what conditions she will be woken up but won't be given any other information, like what day is today. In that scenario its 3 possibilities, It was a Heads, and its a Monday It was a Tails, and its a Monday It was a Tails, and its a Tuesday Thus 1/3 chance of waking up after a heads The second question assumes she knows nothing, not even the conditions on how she will be woken up, so from her point of view a coin toss will always have a 1/2 chance of heads. I wish Derek made it more clear if she knows about the initial conditions because there is no mention of that in the video so we have to make some assumptions.

  77. This video is proof that we are still talking about the 5th postulate.

  78. Derek your aiming protocols makes this seem like a highschool science project, GPS really? You could've used IR lights or lasers to pinpoint the location, thats also what the military uses.
    1
  79. Exactly, I am surprised about how little thought was put into aiming, which was supposed to be the backbone of this whole project.
    1
  80. 10 year old me would ask, why isn't there a laser taped on the nose of the rod for aiming down?
    1
  81. Aliens: Welp, looks like we gotta wait a few millions year more before saying hi.
    1
  82. Exactly! To word it better, "Given the reason you're awake, what is the probability that the coin toss was a heads?"

  83. I love that this format is back. I missed old videos like this!!!

  88. Exactly 😂

  89. Here is a stupid aiming idea that would've worked miles better than the GPS one. Have the sand castle on a RC trolley, fly the helicopter vertically only, when the desired altitude is reached, slide the trolley to the exact spot where the helicopter took off. and of course have fins on the rods lol

  90. Does the sleeping beauty know that her waking up depends on the coin toss?
    1
  91. If you thumbs down it will actually show up in the title.
    1
  92.  @KX36  Because YouTube constantly filters likes and dislikes which it thinks came from bots.

  93. Please do more of this type of videos!

  94. Imagine the world if everyone owned up to their mistakes like Derek.

  95. I think he intentionally mixed two questions to gain some engagement. There could be two questions and both have different answers. "What is the probability that the coin toss was heads?" Answer: 1/2 "What is the probability that the coin toss that woke you up was a heads?" Answer: 1/3 The second answer is assuming she knows she'll be woken up on a Tuesday if it was a tails but not given any information about it being a Tuesday.

  96. 1:34 There you answered it yourself. Its not a controversial Math or Philosophy problem. Its just a Linguistics problem.

  97. The escape velocity is c on the very edge of the Schwartzchild radius. If you move slightly inwards, it's greater than c.

  98. How can humans be so stupid and genius at the same time is beyond me.
    1
  99. That depends on what the question is "What is the probability that the coin toss was heads?" Answer: 1/2 "What is the probability that the coin toss that woke you up was a heads?" Answer: 1/3
