The Simple Molecule Behind Our Complex Universe

Vote for this video by social sharing!

All the complexity in the universe ultimately owes its existence to one of the simplest materials possible: molecular hydrogen. And not only did this molecule play a huge role in building the universe as we know it, today, it also helps us explore it.¬…161L..81C

    I like ur beard 😍
    U just be a model for beards

    *Woah… got a little dark did ya?*

    H2 allow the gas to cool so hydrogen could collapse into stars. We still don’t know how it stayed cool when collapsing… Uhh, that’s a MAJOR point. Not knowing this equates to having absolutely no clue as to how stars formed.

    It would be like a biologist saying “there are chenicals like carbon, nitrogen, hydrogen, oxygen, and phosphorus, I have no idea how they first came together but then there were cells.”

    camera quality RIP

  5. EverNewb

    H2 was the first battery in the universe

  6. Dylan

    that beard created the universe

  7. Hououin Kyouma

    So the universe is essentially near endless could

    Please stop using suggestion banners to interrupt and disrespect your presenters. Terribly annoying.

  9. Le Quasar

    Donald trump like that vids. Not for the content but for the tanning ;)

  10. Ernesto Acompa

    You my friend, remind me of Kratos.

  11. Gro Patapouf

    Thank you. I hope aliens will be able to dig all your teachings out of my brain.

  12. Matthew Demers

    Why you orange tho?

  13. A Diabetic Jedi

    Ok I’m not the only one wondering if he got a tan lol.
    Cool little vid. Thanks for the refresher sci show.

  14. ProKiwi

    This man really could be Neil deGrasse Tyson v2

  15. Tom Larson

    So what you’re saying is if gas is glowing, gas is slowing.

  16. Bruno Lucena

    Why is the image at 3:51 blured?

  17. Toughen Up, Fluffy

    It took 380,000 years to cool down to 3000 degrees Kelvin.

  18. Paul Hewitt

    wait…did you explain why CO is a proxy for H_2?

  19. huckpo

    Jason momoa but if he was a nerd

  20. The Exoplanets Channel

    Anybody else waiting for a video about Venus?

  21. Peter G

    ( ͡° ͜ʖ ͡°)

  22. smellycat249

    How the hell did you get so tan?

  23. Veronica Abbott Cazares

    Oh look! An authentic Petrucci’s Beard! 😄

  24. Osmosis Jones

    How about sending microwaves through the walls to redirect the flow of electrons . making it easier on conventional rockets.
    Another idea I had how to move mass . panels on wheels with in a fluid with in pipes with in the walls. Moving much of the ship’s weight

  25. Daxxon Jabiru

    He forgot to give props to Jebus.

  26. Dan Nowlan

    You cannot casually say that CO- is a good proxy for H2 without some explanation why. That doesn’t make intuitive sense.

  27. Paul Rondezca

    If I’m not mistaken, FRH (flameless ration heaters from MREs) produce hydrogen gas. I’ve come to associate the smell with slightly warmed food

  28. Zaher

    The thumbnail looked like ben wa balls 😅🙈

  29. Hairless Ape

    There’s a lot of hydrogen because it’s so easy to make? I’m not sure exactly how long after the big bang this is true, but at one time everything was hydrogen and helium, and the vast majority was hydrogen. It has still not been used up. Please don’t create the impression that it has been used up and then produced again in general, this would only have happened to a small part of it.

  30. bret hammell

    What was meant we he said carbon monoxide is a proxy for molecular hydrogen? Thanks!

  31. Francesco SkZ Mauro

    One important addition:
    Why observing CO instead of H2?
    Because H2 is a simmetric molecule, on the contrary of CO, so it doesn’t emit as dipole, but only as quadrupole. this means that to have a sufficient emission H2 have a temperature of ~500K (~230C), while Interstellar molecular gas clouds have a mean temperature of few tens of K.
    CO is really more emitting than H2

  32. Aerik Forager

    @2:41 Perhaps it didn’t “remain cool” so much as the universe is a pretty big place and the Big Bang as is commonly described, is essentially a massive stellar expansion that got really complex internally. Perhaps the heating from compression, was/is mitigated by the cooling of the continued expansion. ;)

  33. the guy the name

    3:10 your wrong.

    Molecular hydrogen/hydrogen is not the most abundant form of mater, it’s whatever makes up dark matter.

    And well dark energy is not matter it would make the similar difference and scale to dark mater.

    It’s like trying to compare a grain of sand to a galaxy.

    Dark Energy & Dark Matter

  34. Stevelk

    Great show. If I may be a bit tongue-in-cheek I would say that this episode was mostly about energy and your narrator has just a bit too much. He’s very good except for that.

  35. Spolan The Dolan

    Weird lighting or filter on this one.

  36. Zeldas Champion

    Why is a dark filter being used for this video, Hank? BLM perhaps?

  37. Dag

    From where did all the energy come that created our “universe”? I like the big bang theory but we really haven’t much knowledge regarding the existence of anything.

  38. indianastan

    Sorry don’t believe in the “”big bang”” theory

  39. Human Person

    As I learned the formation of H2 meant a halving of the Amount Of Substance and therefore a halving of the gas pressure counteracting gravity, being able to trigger the collapse of a gas cloud.

  40. Gelgamath _

    1:07 Lol molecular hydrogen looks like a boobs

  41. Tom Clark

    Amazing how we still struggle with E=MC squared. Einstein was a true genius who cut through hubris to see reality.

  42. Jonas Lillard

    Now thats a cool idea; suppose the edge of the universe looks like a bright light then?

  43. spectablis

    Wasn’t Hydrogen an element before it was an molecule?

  44. Joe Cowan

    With all that hydrogen around billions of years ago, thank Christ there weren’t humans around to light a cigarette with a match, otherwise it would have been all over red rover. Like goodbye Hindenburg. Then we would all still be hanging around for the next Big Bang. I’m still waiting for my first

  45. shandya

    I thought my screen was dim

  46. Pugz4Life

    Isn’t most hydrogen in the universe deuterium?

  47. Zazz Razzamatazz

    I like it when Science Will Sasso explains it for me :)

  48. FireSnake

    Wait wait wait, Reid you clossed over something there….
    How the actual f… does CO make a decent substitute for H2?^^
    I surely the disribution can’t be the same, not to get me started on the abundance.

  49. LanDi3000

    This guy is too likable to hide behind a beard.

  50. Andrés B.S.

    This video scrolled through all of my wallpapers…

  51. jaden summer


  52. William Lee

    Does he look like 7 shades more tan than normal to anyone else? Damn near thought we had a new black narrator for a second

  53. Florance Marina

    I really thought I was listening to Neil Tyson Degrasse.

  54. Sergi Koms

    nothing can go upwards, everything goes downwards only – this is Physics,
    – nothing can emerge and develop from matter, everything goes only to the simple, to zero.

  55. Illien Galene

    Wait the laws of physics say: Energy can’t be destroyed.
    Where is all the heat energy?!😱

  56. Slayer 96 DA 2ND

    Don’t worry everyone it’s just photons acting up again

  57. George Stratton

    “Let there be Light.”

  58. uniquespellingfayl

    2:05 that’s not how hydrogen molecules vibrate. The distance between the molecules oscillates but not the center of mass

  59. Jordan W

    How has the potential life on Venus story not been covered yet?!?!

  60. XSportSeeker

    Boy, let me tell you about this simple molecule, boy.

  61. Jari

    If there is a second parallel unviverse then it might be connected to ours just like the bond between hydrogen molecules -since its drifiting apart the force to keep them together are expaning out universe and the parallel.(maybe)

  62. Aeronor2001

    Would single hydrogen atoms not also have cooled the universe through photon emission? Is there a reason it had to be molecular hydrogen?

  63. serybuff

    A few milliseconds of pause between sentences, it’s a bit annoying

  64. WildStar2002

    Waitaminute! 0:17 The universe *is* ‘just full of hot swirling gas’. 😦 I discovered this fact while discussing politics with my neighbor over the back fence… 🙈🙉🙊

  65. Locut0s

    That cubical model of the reionization of the early universe is stunning! wow!

  66. Patrick Aycock

    This video is from the future as reid is clearly red-shifted.

  67. ferretterrier

    If we had a powerful enough telescope, could we observe the beginning of the universe?

  68. Kenneth Hicks

    Um, didn’t realize it was late that we actually measured it. Ty

  69. Akuello The Judge Of Gods

    These titles are like the easiest game of guess that pokemon ever

  70. Devlin McGuire

    SciShow: This episode is all about you little buddy! Ha ah! Take it all in little guy. This is called “Admiration”!

    Hydrogen: Continues to be a small inanimate chunk of mass.

    Hydrogen: (Combust)


  71. merlin nuñez

    Every time I see Reid on the thumbnail I just put on my headphones and enjoy his voice

  72. Dewy Wannamaker

    Anyone else thinking “boobies”?

  73. Binarokaro

    Imagine if h2 molecules across the universe just started getting broken back down to atomic hydrogens at an astronomical rate to the point that the entire universe just starts heating back up

  74. Suvi-Tuuli Allan

    What is Vsauce doing here?

  75. Robert Munroe

    Way to get teens involved with science introduce them to h2 molecules vibrating

  76. Charles Brightman

    Question: If we bombard a crater on the Moon or Mars with protons, could we eventually generate water (H2O) in that crater? If so, potentially a game changer.

  77. Canuck Fundy

    As the universe expanded, and the contents became less dense, wouldn’t that have reduced the interactions of the molecules thereby reducing the temp?

  78. procrastinator99

    On September 22nd, of the year 2020, the Scishow: Space camera did an oopsie….

  79. MonkStar

    Reid found the dark matter. Wow. ^^

  80. Gemmel

    Who else hits the like button before you watch the vid?

  81. JebClang

    Always glad to see Reid hosting. His voice is awesome… and now it matches his beard very well

  82. Jonatan Romanowski

    Go go Sci Show

  83. VivaChandles

    The lighting looks weird

  84. Luke Molyneux

    Somebody’s been tanning

  85. Julio Jimenez

    I just watched a sci show space video hosted by Reid FIVE years ago. His voice has deepened nicely since then. He just gets sexier with time.

  86. HonorableBoor

    Lets discuss the science of using a darker green screen background to affect the contrast of lighted objects in front of them. We can use the bright reflection in his twinkling laser eyes at the start of the video as a standard candle.

  87. GlitterJuice

    Lex did superman hit you with his laser eyes?? i hope you got ’em good for it!! thanks!

  88. Benji Sun *Moxie*

    Reid: if it hadn’t cooled down … atoms wouldn’t have been able to settle down … owe its existence to one of the simplest materials possible.
    me: ice cream.
    Reid: …molecular hydrogen
    me: oh… gotcha! Dippin’ Dots.

  89. Gilgwath

    The universe includes Reid’s beard …. a truly stunning feature.

  90. IntrepidFraidyCat

    PERFECT TIMING! My son is learning about this topic in class this week. Thank you! I’m definitely going to have him watch this. 👍🏻

  91. mrdonetx

    He looks awfully tan to have been sheltering in place and social distancing for the past 8 months…

  92. Sensėjus Faršas

    Looks like someone is from the vacation

  93. The Boulder

    Behold: Dark Mode Reid!

  94. First Last

    Nevermind him looking like he quarantined on the beach, I’m jealous of the beard growth too lol

  95. IrfanHomes

    Reid changed race in this video lmao

  96. HenryManson

    why is this video looking sooo “fuzzy”?!

  97. Kenneth Kustren

    “ROFLMAO !!”

  98. bruinflight

    Hydrogen: building the universe.
    Humans: reverse engineering the universe.

  99. Alan Murray

    Jesus Reid, did you go on holiday to the Parker Solar probe😂😂😂

  100. The Chugs Boson

    This guy is the best narrator. He reminds me of the Ninth Doctor.
