The Beginning of Everything — The Big Bang


The Beginning of Everything — The Big Bang

The beginning of everything. The Big Bang. The idea that the universe was suddenly
born and is not infinite. Up to the middle of the 20th century,
most scientists thought of the universe as infinite and ageless. Until Einstein’s theory of relativity gave
us a better understanding of gravity, and Edwin Hubble discovered that galaxies
are moving apart from one another in a way that fits previous predictions. In 1964, by accident, cosmic background
radiation was discovered, a relic of the early universe, which, together with other observational
evidence, made the Big Bang the accepted theory in science. Since then, improved technology like the
Hubble telescope has given us a pretty good picture of the
Big Bang and the structure of the cosmos. Recent observations even seem to suggest
that the expansion of the universe is accelerating. But how did this Big Bang work? How can something come from nothing? Let’s explore what we know. We can ignore the beginning part
for now. First of all, the Big Bang was not
an explosion. It was all space stretching
everywhere all at once. The universe started
very, very, very small and quickly expanded to the
size of a football. The universe didn’t expand into anything,
space was just expanding into itself. The universe cannot expand into anything
because the universe has no borders; there is, by definition, no “outside”
the universe. The universe is all there is. In this hot, dense environment, energy
manifested itself in particles that existed only for the
tiniest glimpses of time.>From gluons, pairs of quarks were created,
which destroyed one another, perhaps after giving off more gluons. These found other short-lived quarks
to interact with, forming new quark pairs and
gluons again. Matter and energy were not just
theoretically equivalent, it was so hot they were practically
the same stuff. Somewhere around this time, matter
won over antimatter. Today, we’re left with almost all
matter and nearly no antimatter at all. Somehow, one billion and one matter
particles were formed for every one billion particles of
antimatter. Instead of one massive ultimate force
in the universe, there were now several refined versions
of it acting under different rules. By now the universe has stretched to a
billion kilometers in diameter, which leads to a decrease in temperature. The cycle of quarks being born and
converted back to energy suddenly stops.>From now on, we work with what we have. Quarks begin forming new particles,
hadrons, like protons and neutrons. There are many, many combinations of
quarks that can form all sorts of hadrons, but only very few are reasonably stable
for any length of time. Please take a moment to appreciate that
by now, only one second has passed since the beginning of everything. The universe, which has grown to one
hundred billion kilometers, is now cold enough to allow most of the
neutrons to decay into protons and form the first atom, hydrogen. Imagine the universe at this point as an
extremely hot soup, ten billion degrees Celsius, filled with
countless particles and energy. Over the next few minutes, things cooled
and settled down very fast. Atoms formed out of hadrons and electrons, making for a stable and electrically
neutral environment. Some call this period the Dark Age,
because there were no stars and the hydrogen gas didn’t allow visible
light to move around. But what’s the meaning of visible light,
anyway, when there’s nothing alive yet that could have eyes? When the hydrogen gas clumped together
after millions of years and gravity put it under great pressure, stars
and galaxies began to form. Their radiation dissolved the stable
hydrogen gas into a plasma that still permeates the universe today
and allows visible light to pass. Finally, there was light! Okay, but what about the part
we didn’t talk about? What happened right at the beginning? This part can be defined as the Big Bang. We don’t know at all what happened here. At this point, our tools break down. Natural laws stop making sense,
time itself becomes wibbly-wobbly. To understand what happened here,
we need a theory that unifies Einstein’s relativity and quantum
mechanics, something countless scientists are working on right now. But this leaves us with lots of
unanswered questions. Were there universes before our own? Is this the first and only universe? What started the Big Bang, or did it
just occur naturally, based on laws we don’t understand yet? We don’t know, and maybe we never will. But what we do know is that the universe
as we know it started here and gave birth to particles, galaxies,
stars, the Earth, and you. Since were ourselves are made of
dead stars, we are not separate from the universe; we are part of it. You could even say that we are the
universe’s way of experiencing itself. So, let’s keep on experiencing it, until
there are no more questions to ask. Subtitles by the community

    To be saying this, would also be saying you believe that science always existed even though something had to create it, and that it knew exactly what we need to live and where we need it

    Read the Bible, then you will know how everything began–


  15. Speed stars ! says:

    Before the Big Bang there was probably another universe that collapsed by its own weight, which exploded heaps of matter. That could of made the Big Bang. the universe, space and time never ends its a life cycle

  16. Chillness says:

    I wonder, do scientists have discovered the center of the universe already?

  29. Juan Carlos Rodriguez says:

    The Big Bang Theory is not a theory about the beginning of the universe. It is a theory of how the universe came from a super dense state at 10 to the -34 seconds to what we can observe today.

  30. conosci conosci says:

    What if the universe came from the result of a phenomenon from another universe with different laws of physics?

  31. Felix Melton says:

    Hah, i like it how you say that we might not know something, if enough time is alloted then theoretically pretty much anything can be learned

  32. 이도현 says:

    I've been thinking about this for a long time.

    If the mass exceeds a certain value due to gravity, it may expand and consider it a big bang.

    I think the big bang could be many or circulating.

  33. scraperindustry says:

    "The universe isn't expanding into anything, it's just space expanding into itself" — my mind can't even wrap itself around that concept. 🤯

  38. Olga Pagan says:

    I can’t believe people really fall for the Big Bang theory. Crazy to believe such perfect and amazingly beautifully creation came from nothing. If these scientist were doing their job right they would find God. They don’t know what happens there they are working on it. They’ll find it when they die and come face to face with the creator. Ready to be judge for deceiving millions into hades. There was a Big Bang don’t get me wrong, but it was God’s Big Bang. He is the one that made all that noise. He spoke and all nature and science follows. With his breath the planets were formed. Think about it. Sound is vibration. Our voices make sound. Our breath produces vapor in the cold. Every thing was dark and cold until God Spoke The Word and it is so!!!! Thank you Jesus for such beautiful planet you’ve given us. Although now it’s going nuts and out of order thanks to us humans polluting it with filth and sin. Wake up people!!! Stop letting the governments lie to you.

  39. RaPter Inc says:

    Wow we religious people are mocked at when we say God created the universe! So i decided to come and take a look at what this whole big bang theory is all about and see that there are a whole lot of unsolved theories that you people bet on and question what's what God has created. Lol have a fun time in hell 👋

  40. Daniel Blair says:

    I'll stick with what the bible says because it's the truth.

    God always existed and he created all that exists.

    Perhaps the video reveals the details of how God created everything I'll allow the possibility of that, but God was the force and power behind it all and he did it in six days as the bible states.

  41. slim shady says:

    National geographic also has a video on big bang and it is much better than this one.

  42. Esben Maaløe says:

    to the little blackbird at 1.37 – I'm not sure our cognition developed in order to avoid having babies, although I'm pretty sure that it has hindered a lot of would-be sexual encounters 😛

  43. Kenneth Ballena says:

    My life matters now

  44. we need nothing but Peace&joy says:

    Now let me ask this why was the universe born don't hate me for asking this its only logical.

  45. Chris Russell says:


    wait, is that avoid being killed by tigers AND making babies, or to avoid being eaten by a tiger to CONTINUE making babies?

    cus if its teh first one, we really stuffed that idea up…

  46. The Diehardsaint2 says:

    5:21 is just a great value version of Neil DeGrasse Tyson’s “We are the universes way of knowing it exists”

  47. you me says:

    Human: why are you exist?
    Universe: IT JUST WORKS

  48. Lal Awmliana says:

    How long did the big bang happen?

  49. David S. says:

    holy crap this gave me an amazing idea

    Also known as the limit of questions, a coined term in the AMAZING 2005/06 anime Eureka Seven. You want an anime to mind fuck you and make you cry? Boom. Thanks kurzgesagt!

  51. Ay lmoa says:

    Heavy:I fear no man…but that thing…*Points at picture of NOTHING* it scares me….

    Imagine if our cosmos and universe is billions of light years in size (hard to even comprehend the numbers in scale) and imagine that there is border somewhere even bigger then universe…..welp no sleep tonight ;D

  52. Prathap Kumar says:

    The way the mind goes blank when thinking how it all began and whats outside of it. My brain is just like "nothing nothing" what a weird fucking feeling

  53. carson mayo says:

    It's weird af to think that this shit actually happened

  54. Sara Daniels says:

    this is fake!!!!!!!!!!!!!

  55. Mass Kreations says:

    The universe is a living being. A child is conceived and its cells begin multiplying and it grows. So within that baby it would seem as though everything was moving away from each other. Thus it is finally solved. The universe is a living being and we’re the atoms and blood cells of it

  56. Omar Reda says:

    So where did the first quark come from if there was nothing

  57. Slap Him says:

    The thing is. Does the universe reset ever and repeat itself many times? We will never know I guess unless we find evidence of this. I am super eager to see if this is true.

  58. HHQB SM says:

    BOOM! wow something came out of nothing!

  59. aj0nfaiwnfg says:

    wow the universe is pretty crazy

  60. Frankbrooo says:

    All I want to know is where everything came from. How did space come from the “nothing”?” Even if there are laws we can’t comprehend doesn’t there have to be something to cause the Big Bang? I believe in the Big Bang. It just makes me frustrated we don’t know how it came to be yet. Those who might counter with the higher power creating the universe…. my counter is how did the higher power come to be? God(s) are things too how did they get here?

  61. Skar Dragon 19 says:

    Food for thought the big bang could be a massive white hole. A black whole take in matter and sucks it in right, and in another video of yours that was talking about worms holes might help proves that. In that video you all did say a black hole and a white hole night be a worm hole, but it would be so far apart that it seems forever to get to the white hole, so by the time the universe dies the white hole are pushing out matter from our universe to another. Remember white holes pushes things out violently and hot, so it leads back to this video about the big bang. The same thing is going to happen to our universe when every star dies out. Idk I seen a lot of video about the universe dying had me thinking like a mad man especially when you all says the universe will be dead forever. I believe that if something dies something is born right behind that.

  62. Harith Imran says:

    So what created tht "all space" before it expands?

  63. Callum says:

    What if the universe is a living thing and we’re cells except were the cancer killing our planet?

  64. Greyscale / Greypool says:

    What if the universe never disappeared at all, what if exotic matter, the stuff that could hold open wormholes, won over the force of gravity, reopening the universe into the hot energy soup to "rebirth" it.

    How's that for a good theory?

  65. Due and wolf brothers says:

    awww i like that intro i wish it was back!

  66. Jason Buben says:

    So matter or mass isn’t supposed to create more mass or matter but yet space expanded and planets were created? Created by what or WHO?
    Do I need to remind people this is a theory not fact

  67. peachii qloss says:

    my brain hurts

  68. MGaspar22 says:

    So this video should be called… we don’t know!!

  69. Barking Bot says:

    how does the earth orbit if the big bang caused everything to expand?

  70. Mr. Play The Funhouse Trickster says:

    I have a theory on what caused the big bang. A cosmic creator entity. (I try to think of it in other ways but no other theory makes sense to me.)

  71. Isaiah Hernandez says:

    God made this universe

  72. Jordan Hicks says:

    if you cant have like 2x but x=infinity, yea so if that doesnt work than
    so a circle infonitley big would be a square cuz the distance between the oohhhh it doesnt have a center, but if it did the distance to all edges would be the same, like a circle but the universe could be a cube and a cricle ?????????

  73. mickey anderson says:

    YAHWEH is Creator of All

  74. Jeet Vasani says:

    Can there be another Big Bang?

    JK, anyway it's good to finally watch a video that won't send me screaming to a therapist.

  80. Mar.K says:

    Came here not to find a simple explanation.
    Was not disappointed.

  81. Ibrahim Syed says:

    if there is nothing than the universe what was the universe inside of when it was the size of a football is this just the observable universe that we can see and beings that are in the fourth dimension can see more of the universe than us and are we considered a fourth or even an eighth dimension to lifeforms in a smaller dimensions than us and we are much more power full than we think we really are

  82. Mason Myers says:

    It still doesn't tell me how something comes from nothing. If so, then should we not be teaching this theory if we have not given any solid evedence, and why is it called a theory of no one has ever really proved the Big Bang exists?

  83. fknAbe says:

    After years of contemplating this question "What started it all" i came to the conclusion wondering wont benefit anything because NO ONE will never know exactly how something comes from nothing. Sure we can attempt philosophize answers but then again, all of it will be a theory. Instead of worrying about all of this and having what I see in the comments "existential crisis" I realized that we're only hear for a limited amount of time and that wondering wont solve anything only enjoying the experience the present not the past nor future is what benefits us as a person, this experience of living is truely ONCE in a lifetime, and regardless if we found the answer to a question that cannot be answered enjoying the present is truely a gift. By all means if you want to keep questioning because that's just whats in you're nature go ahead! But this is what I stand by and potentially always will.

  84. z50king29 says:

    The only constant is change

  85. we need nothing but Peace&joy says:

    I don't get it by what the means the is no outsized then universe that's like saying the is nothing but the universe but why the hack does the universe exists if the cannot be an outside the can clearly be no boundaries to the universe expansion so by that logic energy might have just jump started out of the blue into an size of an football for some reason then the narrator said energy manifested itself into an particle eventually into matter so that's how our universe come to be seems so legit.

    "to avoid getting killed by tigers and making babies"

  90. casperld says:

    But where did all this shit come from in the first place and why were there reactions to each other. Fuck this shit. Im goiing back to believing in God

  91. JAIDAN LASALLE says:

    i may not know how everything began, but I have an idea of how we came to be, just hear me out. I'm not trying to copy anyone if this is already something someone has thought of, i'm just putting it out there.

    all actions require energy to perform right? well what if all of this had happened before, but on a much larger and slower scale. if the universe is currently expanding, wouldn't it retract due time? I think of the universe is kinda like a rubber band, where once it stretches to it's maximum, it comes back to its original state, and continues vibrating. with every retraction/expansion, it loses kinetic energy, and the scale of retractions/expansions becomes smaller.

    i'm not a scientist, just a 14 yr old in the 9th grade, so you don't have to believe me :/
