      Understanding the 5th level makes me feel smart

    2. 100 yen

      level 1: americans

    3. Mclaren Rising

      Its a shame to come across a great scientific educational video and then find that flat earthers have infected and poisoned the comments section.

    4. Shine Thief

      I am very proud of myself that I understood maybe 5/8 of level 5.

    5. Amanda Renyard

      Thank you for featuring a female intellectual. Let’s push for racial diversity next go!

    6. GringoLingo

      12:50 College student: “mmmyeah. mmmyeah. Yeah. Yeah. Yeah.”

    7. Haden Derrington-Holburn

      level 5 was just physicist foreplay, they 100% big banged after this xD

    8. TrumpForPresident 2020

      The teen seemed like she knew less then the youngling

    9. Nebula Cheese

      guys pls believe me im smart

    10. Edwin Rodriguez

      The humdrum united kingdom coherently squeal because bridge ostensibly peep in a abounding step-son. cloistered, vast roll

    11. FunkyCyclist

      I really got lost. The little girl is way smarter than me. 🤦🏻‍♂️

    12. Dante Pedro

      the discussion on the college student up to the post grad, even though i watched it with subtitles so that i could read and hear the explanation at the same time, i still couldn't understand a thing lol

    13. JustLouIt

      It would have probably been better if a man explained it

    14. Arpan Doshi

      At every level except the 5th editor had an example video clip.😂

    15. Kataang101

      Interesting on the expert level. Never heard of holography or that it could be possible that our three dimensional world is just an illusion and it really is just a 2 dimensional world.

    16. Reflecting Both Sides

      I learned we are just fancy dressed monkeys that will repeat anything. Gravity. Lol. A.k.a “Atmospheric pressure + centrifugal force”.

    17. Jian Lachenal

      There should be a Level 0 for flat earthers

    18. Sir Michael Fuzari

      Her: mhm, mhm, mhm, mhm, mhm, mhm Him: mhm, mhm, mhm, mhm her: mhm, mhm, mhm, mhm, mhm, mhm, mhm, mhm, mhm, mhm him: mhm, mhm, mhm, mhm, mhm, mhm her: mhm, mhm, mhm, mhm, uh huh, mhm him: mhm, mhm, mhm, uh huh her: mhm, mhm, mhm, mhm, mhm, mhm, mhm, mhm, mhm, mhm, mhm, mhm, mhm, mhm, mhm, mhm, mhm, mhm, mhm, mhm, mhm, mhm, mhm, mhm, mhm, mhm, mhm, mhm, I love you him: uh huh.

    19. Chandra Kiran Narala

      35:10 Science Joke!!!

    20. HOLY SPIRIT

      Oi josuke, in my dream she gonna challenge them to steal her stand disc a month later, ain't that wacky?

    21. Smith Chinx

      I want her to teach me. she made feel so easy

    22. Justin Mart

      The Expert. He gives a real Ben Shapiro Vibe. It's crazy

    23. cryinglowkey

      Take a shot Everytime she says "like"

    24. ViVi May

      The college student continues "yeah" and "uh hmm" is distracting 😅

    25. M L

      Scientist: (gives fun facts) Child: (existential dread)

    26. Manny Fox

      Gravity is fake. If you know about density it's all so much easier to understand. peace

    27. Spicoli

      PepoG

    28. heyRZ

      That little girl is smarter than my ex

    29. jose giron

      ok good I'm on the grad level barely but I'm glad my BA wasn't for nothing lol

    30. Craven Moorehead

      Like like like like like.....this girl is the brightest they could find?

    31. Samuel Eto'o

      She did absolutely fantastic. Some of these get cringy but she had my full attention the whole time and was able to bring the most out of the ppl she spoke with. Awesome awesome video

    32. Crispy Hippie

      How can they explain something they don't understand? They literally just discussed what they think it is and didn't explain anything lol

    33. Obscure Reference

      6 people more educated than me.

      1. Obscure Reference

        nvm I just saw the 16 year old.

    34. randall goldapp

      I'll explain it in the only way that matters to me: fall down, go boom.

    35. The Matrix

      It's so inspiring listening to two masters of their craft discuss their craft.

    36. HitMyWoods nYouChoke

      the child was a better speaker and listener than the college student

    37. The Matrix

      Oh my God. Pause. Wait. What?

    38. AMOF

      I followed everything until 00:34

    39. David Diaz

      I’m between the high school student and college student.

    40. Mashrur Khondokar

      Am I the only one who understood what the experts were saying lmao?

    41. allen schmitz

      You have to be crazy to dispute the sun being 93 million miles away and the clouds are all 66 million miles high, don't be fooled by your eyes.

    42. Poison Toad

      The kid was smarter than the teen lol.

    43. a1175779

      Interviewer: the mother astrophysicist Level 1: her bright youngest daughter Level 2: her average teenage daughter Level 3: their exchange student Level 4: her grad student she’s a co-author for Level 5: her physicist husband

    44. Connection Lost

      And yet her own understanding is that of a bird looking at a time machine's shadow on a wall.

    45. Miroslav Averchenko

      You need to do a lvl 0: flat earther

    46. Jason L

      Level 6: Guy who is stoned

    47. Barry Davis

      Oh before you try to reply to my comment ask the professor if her gravity affects gasses as this is crucial in your reply, I will then expect verifiable evidence that gas can be affected by gravity as I know that NO ball can float inside a vacuum and NO sphere can support a gas exterior while inside a vacuum. Like she is implying Earth is doing naturally.

    48. Barry Davis

      Astrophysicist brainwashes CHILD to believe that Gravity exists right in your face, Poor child will become a bawler then find out it's all a LIE because a ball does NOT float in a vacuum, Newton has been debunked by Einstein so new gravity garbage is it's the bending of time and space. what makes things lighter than the surrounding environment Go UP anti gravity? Things going up or down is easily explained using buoyancy and density no gravity . and fake station is NOT in space or low Earth orbit. see tube for exposure mice in space and loads of other proof NASA does not go into space. It can't.

    49. Gustavo Soto

      Did anyone else start reading the comments on level 5?

    50. Russ Hamilton

      OK so, so strong that light can't escape? I believe she means that since there is no time, that light can have no velocity. Without velocity it can't escape.

    51. Urukosh !

      4:00 Okay so a balloon falls same rate as a rock XD LMAOOO

    52. Major Lag

      Gravity is fake! Buoyancy and density is real!

    53. Kuhmuhnistische Partei: Muht zur Kuhzunft!

      How the ISS stays in orbit: "The knack lies in learning how to throw yourself at the ground and miss" (yes, this is a Douglas Adams quote)

    54. Geanny Lupu

      Title of video *Astrophysicist Explains Gravity* proceeds to explain relativity of seepd to the highschooler.

    55. Hyper UwO

      i just realized how good my middle school science class is

    56. DNK

      what

    57. Adam Essig

      M Y E A H

    58. Spartan_Reaper_777

      the more you know the more you realize how much less you know

    59. Flatten The Curve

      Dahhhh we’d all be floating if there was no gravity. Dahhh Globe Earth is a Religion Fool. It’s just density and buoyancy. Listen to the crazy pseudoscience they pump into children’s heads.

    60. Shaddy Mate

      I'm Gemini! -only some people will get this joke

    61. Jordan W

      Apparently I’m an astrophysicist expert

    62. Serena Roberts

      The high schooler had no idea what she was saying

    63. Mervin Singh

      me at 4:52, learning science but also tired.

    64. TodaVtecKiller

      How is time relative to space

    65. MustardTiger88

      That kid was smarter than the high school girl.

    66. Skellymon

      I like to pretend i understand the conversation between the experts

    67. Ioana

      Instead of saying that gravity is an "illusion", can't it just be said that gravity and its quantum counterpart theory are simply different levels of analysis of the same phenomenon?

    68. Golden Maximo

      3:53 this is something they teach wrong at schools and I always got mad because of it. Things do not fall at the same rate here on earth because of the atmosphere, you have to take into account the air resistance. So answering the girl's question, no they would not fall at the same time.

    69. the only max

      12:53 I don’t wanna harass her, but her „yeah“ annoys me, it sounds like a sample played over and over

    70. VillaMasterSF

      to this day no1 knows actually what causes gravity so scientist just take as granted as this force thats just there but what quantumthing or whatever is causing it is unknown.

    71. nothingofCal

      28:35 He explains spaghettification so flirtatiously haha

    72. Ok

      26:09 Guy: Imma flirt with you Lady: Get you sh*t together.

    73. Abdiel Morales

      this is pointless its just for views

    74. Josh

      the teenager looks exactly like the child

    75. Todestuete

      The next video in my queue is Slap God vs Slap Demon.

    76. rickyjoeshippyful

      The comments area as good as the video! lol

    77. T T

      they talk about physics but I‘m sure that there’s some chemistry between her and the expert too 😳🤚

    78. John RodGrøm

      So, to oversimplify it, gravity is a magnet!!!

    79. Aaron Rubenstein

      Why’d the child seem smarter than the teen??

    80. James Paul Tinsley

      Level (.5) one-half = Trump voter.

    81. tripniD

      my level of understanding is "child"

    82. Adhithyah G

      at 7:00 its actually 11.2 kms per second its called escape velocity

    83. Manoj Giri

      I went to level 4 but after that my brain giveup.

    84. Siah

      Level 1- Kid: Falling ball Level 2-Teen: Idk what you said but yes... Level 3-College Student: Mhm.. yah Level 4-Grad Studnet: I know some stuff :) Level 5-Expert: Why am I here, I already know everything...

      1. LifeofEntropy

        did you not watch the video? the experts whole discussion boiled down to "I know nothing and thats exciting"

    85. I pex

      Interesting how I am not explicitly educated on the topic of gravity and English is not my first language vut I was still able to grasp most of the concepts even on the expert level. What a great video!! I think I've never learned so much in the matter of 36 minutes.

    86. dead pres

      please parents, don't let your kids use the word "like" as if it was a comma, at least not before they learn how to properly use commas. jesus christ.

      1. dead pres

        imagine this sentence like this: "Like, please parents, like, don't let your kids, like, use the word like, like, as if it was a comma, like at least not before they learn, like how to, like properly use commas.

    87. Osmond Go

      Not a lady but I want Janna's shoes!

    88. Feng DXM

      26:10 "...like you, that's one of the things that really pulled me into it."

    89. Turner Manc

      everyone wants to be a comedian...sheesh 26:11

    90. Crunchy_Bob

      God and I call it The Great Gravitational Dance Of All Cosmic Bodies, that guy, he's such a kidder!

    91. VIBE

      I feel like the intelligence of a person isnt determined by how eloquently they speak, but how they can explain complex things in a simple manner.

    92. Putu Walling

      My life is revolving around the kid level 💔

    93. marble

      I didn't like the condescending"looks the "expert" was giving. Dude, this is a video. Calm your ego.

    94. ParaPutty

      level 6: flat earther

    95. sixpool

      i weigh 200kg, so i'm somewhat of an expert on gravity myself.

    96. River Lend Canal

      In times of depression learing about physics can soothe your senses

    97. FatBox

      Is it just me or does that astrophysicist at the end sound just like Tony Hawk?

    98. paige jackson

      I have learned we may be in a holographic simulation thank you for confirming my fears

    99. Jason Ricco

      Gravity is easy it means to have weight in latin there is only density and buoyancy thats it. The apple had weight the stem couldnt hold onto the tree it fell on newtons head nothing pulled on the apple no magical force at all. Newton also wrote demonolgy how to conger demons what a guy. Use your heads people. Block of wood on a table gravity lol now throw it in a pool of water it floats where did gravity go???????? density and buoyancy thats it. This lady is a joke like gravity words cast spells

    100. Gabzsy

      Okay, am I the only one that noticed that the 16 years old explanation of what gravity is was as poor and shallow as the little girl one? And you can tell that most of what the astrophysicist is saying to her is flying right up her head. USA educational system really do sucks.
