  • How did everything get started?

    Has the universe a beginning or was it here since forever? Well, evidence suggests that there was indeed a starting point to this universe we are part of right now. But how can this be? How can something come from nothing? And what about time? We don't have all the answers yet so let's talk about what we know.

    Also, we try to make this one not depressing. Tell us if we succeeded.

    BY THE WAY. We have a website now. We'll try to blog from time to time, show you guys how we make the videos and give more insight to our process. Also we sell stuff. We really don't know where this whole kurzgesagt stuff leads us. But we are really thankful for all the attention and positive feedback and yeah, maybe we can make this our jobs -- it would be pretty nice and we could do more content each month. But we'll see. For now, thank you very much everybody for making this little adventure possible.

    Thomas did an aweful good job again. :)

    Next Video: April. (as soon as we can but we kind of have to make a living and visit college) Topic: Nuclear Energy (probably, if we finish the research in time -- if not something else)

    Short videos, explaining things. For example Evolution, the Universe, Time, the Stock Exchange or controversial topics like Fracking. Because we love science.

      _what started the big bang_ - Nobody really knows - at least for now.
      _it could be god_ - See, the problem with this... explanation is that there is no good evidence for a god.

      _From where did energy came after big bang_
      See, ultimately, nobody knows where the Universe came from - and its components.
      But specifically in the case of energy, it seems clear that energy is NOT conserved in the case of an expanding Universe.
      Energy conservation is explained by Nöther's Theorem - and in the case of an expanding Universe, the conditions for Nöther's Theorem are NOT satisfied - therefore, energy conservation is NOT guaranteed.

        If it created the big bang by default it's God
        322/7
        7/10
        4/24
        4 two from the 7th ray two from the 4th ray created the big bang and the 5 waves of energy by there 3 above 2 bellow merging process by default the 4 are God

                      THE BIG BANG ARE THE GIANT EXPLOTION HAPPENED IN THE SPACE BECAUSE GOD ARE BURNING HER BODY BY USING OF FRICTION BETWEEN DUST AND GRAVITY TO CREATE A MAGNETIC DUST USING TO BUILT A PLANET AND LIFE,,, SUN IS A GOD PARTICLE OR GRAVITY BURNING A DUST IN THE SURFACE, PLANET AND LIFE ARE THE MAGNETIC DUST OR NEBULA

                          Lol that is not a question at all. Time was created at the beginning of the big bang (if it really happened), so you can't just apply the concept of time to the point where it doesn't exist.

                          @Daniel Fausto And that's exactly what I was talking about. What you just described is not what the big bang says. It's a common misconception that the big bang says the universe came from nothing. Here is what the big bang actually says. The big bang says that the universe expanded from a state of high temperature and high density. It does not say the universe came from nothing. Now do you understand?

                        Using big words to hide your lack of understanding. It's like how a politician answers a question, without actually answering it. One person tells a lie, then another repeats it and so on... then suddenly it's science! Such a joke.

                          This is generally-accepted science they are talking about. We KNOW that the Universe is expanding; we KNOW that about 13.8 billion years ago matter in the Universe was very concentrated and very hot; and even though there are details we DON'T know, there is very good evidence for this "Big Bang".
                          (Among the things we DON'T currently know is, what - if anything - caused it.)

                          _Damn back then it was just "NOTHING"_ - Nobody really knows that there ever was "nothing".
                          _How did the universe even existed?_ - Ultimately, nobody knows what (if anything) caused the Universe to exist. It MAY have existed forever, in some form. We simply don't know.

                        Sincere question for the religious folk in this video:
                        Why is it nonsense to believe that the universe was not created by anyone...
                        ...while it is logical to believe that there is a man who was not created by anyone and existed forever?

                          what if we are just universes expanding and expanding and all the stuff we have is a simulation but wait what if we are in a bigger universe with other universes expanding they have a simulation too, and so on.

                                the problem with a big bang is it's a singularity therefor no big bang only hawking's radiation. the big bang cannot happen, do we see black holes exploding. is not a black hole a point singularity? if so, then a big bang is not possible. a singularity is a black hole of infinite gravity and infinite density and only hawking's radiation is all their is, so the big bang didn't happen because singularities do not explode.

                                  The Big Bang may have SOME similarities to black holes - BUT IT IS *NOT* A BLACK HOLE. At least, as far as we know.

                                  The Big Bang is NOT about explaining "what, if anything, created the Universe". It is about what happened AFTER a certain point in time. Which is what we can actually deduce. We currently can't deduce what happened BEFORE the Big Bang (if there WAS a before).

                                      Big Bang theory actually makes a lot of sense to me. You can’t say the universe came from something before there was a thing because that’s an illogical paradox, and showing that there was a singularity, the size of nothing, a particulate of energy, makes much sense because of cosmic background radiation from a point in the timeline when time, energy and space was created. Perhaps we’re living amongst an infinite amount of singularities with potential, in our universe and out of it in a different timeline in anywhere outside of it, if you get me, which you do, right?

                                      There is no way. There are questions that cannot be answered, only to an extent. Where did my conscious come from? Where did the universe come from? Why do we exist? What caused us to exist?

                                      There is no answer. No answer for the first one because it’s a part of the universe and the only thing we can be for sure exists is death, which may be the nothing perspective, sort of like the one outside of the universe where nothing exists, just a block in the timeline where humans and other things cannot travel. You close your eyes and you and the universe part at that very instant when your brain no longer functions, and you, and your conscious are no more. Universe instantly dies with you.
                                      The universe question; answer is very similar because it lies on the lines of there being no answer.
                                      They’re all the same.

                                      Accept this and let yourself come to peace. There is no reason to be afraid of anything in this life you’re living.

                                      After all, everything here is a perception. Our brains would be dead without our bodies.

                                        The thing why I believe in God so much it’s bc even when you do believe in the Big Bang you have to understand the chances of all these being connected n being a domino effect for each other is SO LOW. Mathematicians said the chances of it happening is so low that it’s not possible, it’s deadass NOT POSSIBLE. Everything has a meaning to it. Tress give H2O n we give Carbon Dioxide, men give women children n bam LIFE, shit even the damn moon n sun. If the sun was a couple of inches closer we wouldn’t be alive, that’s crazy if you think abt it. This is why I believe in the Big Bang but I do believe God created it n the main n only reason why we are here. Nature is a beautiful effect that has an amazing mind behind it

                                          _you have to understand the chances of all these being connected n being a domino effect for each other is SO LOW._
                                          1) The chances of WHAT, exactly?
                                          2) How do you calculate these chances?
                                          3) And how do you calculate the chances of the existence of a god?

                                          less heat means slower movement. Molecules move slow in colder climates.

                                                Maybe the universe was void all dark matter or black holes. What happens when all the energy absorbed by a black hole is released. Shooting out massive amounts of energy like a pulsar. Spewing ingredients for life along the way. had to get mixed in the pot before being served.

                                                  idk why religious people deny the big bang... they could reasonably just say that God snapped its fingers and because god is the creator of all things (except presumably itself, which creates a whole new level of philosophical questions) when it snapped its fingers it clearly created a "big bang"... currently this makes as much sense as any conceivable explanation as to why there was a Big Bang in the first place... but that reminds me of what NDGT always says about religion and science, and he says that if you find proof of Gods existence in what science can't explain then God is an ever shrinking entity... considering 3,000 years ago we knew relatively little compared to what we know now, meaning God, at the time, was a much larger entity because science had not yet developed to explain the world around us like it has now...

                                                    1 second? Does that mean that universe exspanded faster than light?

                                                      @Hilmar Zonneveld i was reading about this, and your a both right and wrong. it does expand faster than light but only when u account for big chunks of space if u look for exspansion withing meters than u see its slower, gravity can fight it and we are not torn apart. the light speed isnt realy speed of light, its max speed of info thru space, going faster would mean time pasing slower and slower until it reach standstill.

                                                      Yes. And it STILL IS expanding faster than light. The places that are far away from us move away from us, faster than light.
                                                      Note that nothing can move through space faster than light... but in this case, it is space itself that is expanding.
                                                      This is explained in the General Theory of Relativity... which is not exactly easy.

                                                      Exactly... remember that universe expands faster than light but within the universe light is the fastest thing.

                                                    i dont believe the big bang was tge beginning, but rather one of the many stages of the universe. if all laws were squeezed inside this singularity, there was no before. e=mc2 is to me the signature of the universe, it shows how energy and mass are interchangable and that apparently something is out there that has energy content

What were conditions like at the time of the Big Bang? What happened before that? Was there a tiny universe, devoid of all matter, and then the matter suddenly created from nothing? How does that happen? In many cultures it is customary to answer that God created the universe out of nothing. But this is mere temporizing. If we wish courageously to pursue the question, we must, of course ask next where God comes from. And if we decide this to be unanswerable, why not save a step and decide that the origin of the universe is an unanswerable question? Or, if we say that God has always existed, why not save a step and conclude that the universe has always existed?”

                                                        I wouldn't call them "sub-subparticles". What you mention is called subatomic particles.
                                                        *Quarks:* It is now known that protons and neutrons are made up of smaller particles, called "quarks". It is complicated, but a simplified explanation is that each proton, and each neutron, is made up of three quarks.
                                                        *Hadrons:* The quarks mentioned above can also combine in other ways. "Hadron" is the generic name for any composite particle made out of two or more quarks. Not all of the other particles are made out of quarks; electrons and photons are separate types of particles (NOT made out of quarks).
                                                        *Gluons:* It seems that the four fundamental forces in nature are all mediated via particles. Particles that transfer the so-called "strong force" between quarks are called "gluons". The "strong force" is what keeps quarks together in the composite particles mentioned above; the much weaker (but still extremely strong) "residual strong force" is the part that "leaks out" of protons and neutrons, keeping them together in an atomic nucleus.

                                                          What if much of Physics arises from the interaction of energy with Dark Matter? What if matter and anti-matter did indeed annihilate each other in the Big Bang explosion, but the subsequent gradual nurturing effect of Dark Matter solidified pure energy into matter? This would imply that Dark Matter was always present in the Universe, and was not part of the Big Bang Singularity. Was Dark Matter always here? Dark Matter can perhaps act as a scaffold upon which galaxies form. It may be the way matter forms into solid entities. Have we overlooked the significance of Dark Matter in our Universe by focusing too much on the Big Bang story?

                                                            I've been watching a couple of 'big bang theory' videos and I'm honestly unimpressed with this one. Which is sad because I love Kurzgesagt. I can imagine the difficulty of trying to simplify something so complex but this version does the whole explanation a disservice. Have a look at the Nat Geo or Big Think, 'Where do atoms come from' videos, if you fancy a more scientific structured explanation.
