The Big Bang is the term that scientists use to describe the beginning of the universe. In this video, Fermilab’s Dr. Don Lincoln clears up many common misconceptions about this fascinating topic. To learn more, visit: fnal.gov
What I really appreciate (besides the content) is, that no music is played during your talk to make it seem more impactful. You just don't need music and I can listen 100% to your words. Thank you.
I have a question about elementary particles such as electrons as well as various quarks as well as neutrino particles As well as the article and antimatter Like the anti-electron positron And also the counter quark The question is about why these particles differ in rotation, mass, and charge We hope you find smart plans to reveal the secret of the difference between the elementary particles Was the difference between the particles due to the difference in the proportion of energy in the universe? Why are the primary particles different in mass, charge, and rotation? The third question Are there smaller molecules responsible for this difference? Please communicate my three questions to physicists
@@user-gq4qm2uv3h You should ask the question on the video, rather than as a reply to a comment. You've got lots of excellent questions, and I'll bet this channel has already answered several of them in various videos, and will continue to answer them over time! I'll recommend Fermilab's video titled 'Fermions and Bosons'. Apologies if the formatting came out strange, RU-vid's text-entry field can't decide which language I'm typing.
Surah Al Anbya {21:30}The Noble Qur'An:Do not the Unbelievers see that the heavens and the earth were joined together (as one unit of creation), before we clove them asunder? We made from water every living thing. Will they not then believe?
This really resonated with me too. Like when Ricky Gervais (not a scientist!) commented that science is entirely re-discoverable, like if 1000 years after humanity is wiped out all this can be plausibly reestablished, as a contrast to religious beliefs which may or may not be reestablished (I am easy either way on this, I just sense a vulnerability in the hearsay of more knowledgeably primitive humans).
Dude. SO AWESOME seeing you on PBS SpaceTime yesterday. SpaceTime and Fermilab (only because of Dr. Don) have long been my two favorite channels on RU-vid.
if PBS recruited this guy, then you can rest assured he is completely full of shit and serving you atheist leftwing propaganda....and yes, politics are still involved with astrophysics...because politics is down stream from culture and culture is down stream from psychology and psychology is down stream from associative logic foundations.
Yes, the problem is that scientists don't admit when they don't know something. I read a book once telling me exactly what happened 10^-32 seconds after the big bang.
@@RobertsMrtn it was told you because you can't handle that at that time , I mean Mathematics. When you are at minor school when Someone gave you subtract 10 from 8 then you will be like it's impossible but when you go higher class then you know the answer was -2 . I think from above you may have got an idea how it works.
@@RobertsMrtn "I read a book once telling me exactly what happened 10^-32 seconds after the big bang." - What book was that, claiming absolute certainty under the guise of scientific knowledge?
If they know everything, it is no more science, it's religion. Science is about for what we have enough evidence. If not evidence enough, the question must be left open. Of course, climate science is different...
@@kathylynne8872 then get out of here. If you don't believe a particle physicist from fermilab you're a moron. You should probably go watch your flat earth conspiracy theory bullshit. That suits you.
Fantastic explanation. Your accent is clear and straight forward, your pauses and speed of delivery is precise, there are no musical disturbances, your body language instills confidence in the audience and the l lecture is so splendid. I can listen to you endlessly. Fabulous. I'm bent on learning a lot from you, sir.
I have a great interest in this sort of thing and thought myself fairly knowledgeable about it, and still learned a few things here! Thank you for this!

Really diggin' these presentations by Dr. Lincoln, going through most of them, I love that there's no music as well, a proper lecturer and makes it all easy to understand.
== The Conglomerate - Universe Creation Theory (combining GOD, General Relativity, Quantum Mechanics, and Chaos Theory) "The BIG Bang-Bit Bang inflation/expansion of energy and information into the void 13.8 billion years ago was a supermassive white hole spawned by a supermassive black hole at the heart of a galaxy in our 'parent universe'. This duality combines general relativity’s singularities of infinite density in a ‘Cosmic Egg’ birth of this and all universes within 'The Conglomerate': multiverse without random bubble universes and parallel worlds. Our Universe is inside the Planck density of that SBH and shares the same event horizon. That SBH-SWH seed phase transition was a 'quantum tunneling umbilical wormhole' with energy-matter and data transformed/transferred, albeit scrambled and encoded. Our Universe is 1-in-2 trillion 'self-similar offspring' each with the same inherited physical laws (‘DNA’). This simple cause-and- effect cycle/'circle of life' - birth-life-death-transformation-rebirth - explains both infinite space and eternity. Reproduction is GOD/Nature’s simplest plan for spreading life for everything from cells to universes." - Seal #1a of the 7seals.blogspot.com This has triggered The Apocalypse/Revelation which is not the ‘end of the world‘ - it‘s the 2nd Coming (E=mc²).
I have waited my whole life to find this video. I now feel happy with an understanding of the universe that I didn’t have before. Thank you so much for simplifying this complex topic for me
Great stuff as always, one thing I would add is the misconception of the "before" the big bang people often have as well. Time-space is not a separate phenomenon so when space is condensed to a tiny speck, time also behaves differently and so time very likely began with the expansion itself. There most likely was no "before" the big bang as time simply didn't exist.
There must have been some crazy time dilation shit going on at the BB. All that mass in such a small volume? Also I've never got to grips with how did our Universe escape from it's own Schwartzschild radius ?
Not really; space and time coordinates exist depending exclusively on what atlases can cover a given manifold - whatever it may be. The thing with cosmology could be better put this way: if there was a 'before' the BB, we wouldn't know, because time is kept by clocks made of matter and all matter was bunched (classically) inside a singularity
I am 82; I am not a scientist. But I have developed a strong interest in it. Dr. Lincoln presents his key ideas in a clear, understandable manner. When I think of all the university professors that I had in under graduate and graduate school that mumbled, Dr. Lincoln is refreshing.
It might take a long time to figure it out because things are getting harder and harder. It has been over 100 years since Einstein's groundbreaking achievements. I used to read older astronomy books from the library when I was a teenager. So much has changed since then, incredible!
Even better: He doesn't claim all of them are his,BUT he's probably the best ať explaining them, which is far more valuable to me. Because IT doesn't matter how much of a genius you Are if you Are the only one. Mankind Is only able to move forward collectively, not as isolated individuals. That ship has sailed thousands of years ago.
@Dupa Essex It's how the left gains ground-they do it thru the legislative process by organizing what they want taught. That really should be left to educational experts.
@@kimlibera663 That's the Right doing that, Kim --- pushing anti-science Biblical "education" agendas, Creationism, library defunding and censorship. They're the force trying to dumb down America so they can take over.
There seems to be a disconnect between your wish for more science and your irrational political beliefs. Not meaning to make a No True Scotsman fallacy, but I find it difficult to see how anyone who values a scientific, evidence-based approach can fall for such obvious tribalism.

The Quran also tells us that, at night, the Sun hides in its resting place. If you want to learn how things work, read a science textbook. You're right that there are many negative stereotypes of Muslims. That kind of bigotry is shameful.
@A3Kr0n This Channel Has No Content. SPAMBOT! PBS Promotional SPAMBOT! Actually it's a Dr. Don promotional SPAMBOT that promotes PBS as it associates to Dr. Don.
@@TheMyguitarisblue Yes. No. Most humans reply when you accuse them of being not real. Most. Did you notice the video has no supporting data and "people" love it and call Doc Don the reason PBS is getting better?
Double dose of Don in one week!!! I love your content and have a great appreciation for the work you and ALL of your colleagues do in the world of Physics!
New sub. I heard about this channel from the colab with PBS SpaceTime. Your content seems easier to follow for us normal unedjumacated folks. Keep it up
What really happened at the Big Bang? NOTHING ! Because nothing can NOT create everything ! An explosion will never create anything ! Use your brain for 30 seconds before going back to sleep and believe these pseudo-scientists and their lunacy. THIS IS BULLSHIT FOR GULLIBLE SHEEP... JUST THINK !!!
I agree because Earth is observably, provably and test-ably Flat. Even Neil deGrass Tyson said you cannot see the curvature of Earth from 120,000 feet up.
FINALLY! This is the first clear explanation of the Big Bang. I never understood how can be an infinite universe emerge from a single infinite dense spot called singularity. The answer is: it wasn't the case, just our current theory (Einstein's theory) can not describe it. Thank YOU very much. You are a very good teacher, sir.

szarvasmarha My excitement exactly. I didn’t think the universe was ever a singularity or infinitely dense. And I never thought there was meaning in the concept of T=0. But here it was explained for me that the “observable universe” was the size of a “proton” but possibly existing within an unobservable and possibly infinite universe. And the Big Bang is what happened after inflation ended at around T=10^-32 secs. I’m giddy after this clarification.
Thanks for that. I wasn't sure what the difference between expansion and inflation was until now - I'd thought they were pretty much synonymous with each other (as a matter of fact/event, as opposed to being just words describing a similar concept). I really enjoy your talks, so please continue making physics understandable - at least at this level. I wouldn't dream of saying I understand it academically LOL. Cheers!
@Henrik Wallin Are you an astrophysicist or a cosmologist ? NO ? Thought so. I wonder why you think you know more about their fields than them. There is this Dunning-Krueger effect if you ever heard about it, the point is, the less you know the more confident you are in that you know everything. Such a sad cognitive mistake, I see ppl doing it all the time...
Thanks for your videos and for this explanation... I like your mindset about rather focusing on what we don't know, focus on what we do know and awe about this wonderful universe we live in... but then can't help think how this precious knowledge doesn't serve us to see the same beauty about our existence in this planet and that we still fight for land, resources, territories, power... How can that be
@Andrew Ongais Until new physics and math is created/found to develop these theories beyond speculation, we won't know. I mean I would like us to not have to stay beholden to c, so we can explore the universe at a more manageable rate. We just need better theories and better science to push us forward.
@Andrew Ongais it goes even deeper than physics, science cannot explain the simple, why do you chose to write on this forum? You intention cannot be broken down into chemical impulses of the brain. You have chosen to act and science cannot explain why.

@@Cabolt44 It's a joke, but a serious joke. Far too many people approach science with a religious bias. I know that's not how the OP used the word, hence the joking part.
Time is quantized, too. The Plank time unit is 10^(-43) seconds and prof.Lincoln says we can't know nothing betwee t = 0 and t = 10^(-43)s. A quantum gravity theory could help, but it doesn't exist yet
"Well nobody was there at the time, so we can't possibly know anything" If someone told me that I would ask them, if your house got robbed and nobody was there at the time, but there *was* any kind of DNA to trace back to the culprit, would you dismiss it because simply nobody was there at the time? 0:37
Yeah I'm afraid people claiming this are never going to learn anything. So with that logic, there were no dinosaurs, right? Even though we found their fossils.
@Johnny Mnemonic Well, see, you are kind of committing a false analogy fallacy because we aren't talking about DNA when we talk about the big bang; We are talking about electromagnetic radiation from the CMB.
Thank you for this cogent explanation. I have heard so many scientists use the term singularity and infinitely small or infinitely dense to describe the early universe, or black holes. Maybe they are just sloppy in their terminology. It always gave me the impression that they didnt know what they were talking about, or were treating the public like children.
Hello Dr Lincoln. First of all I am a very big fan of you and also Fermi lab☺️☺️. Your video series about so many topics on particle physics and cosmology where you explain them simply but not too simple is really fascinating ☺️. I have some questions that I do want to ask you but I don't know how much valid are they. 1. I have heard that electrons does not have any size but they contain mass and charge. So don't they create singularity? How are they different from a miniscule black hole? 2. Does big bang violate the known conservation laws? Will quantum gravity theories always maintain the known conservation laws? 3. As much as I know which can be wrong the velocity of light in free space from every frame of reference is always constant. So how does velocity can be constant when it is relation between distance and time (I don't know if I said it correctly) 4. Also in the movie interstellar Cooper jumps into the black hole in hope of knowing about singularity and thus solving quantum gravity. But doesn't studying the wormhole which is created by using the laws of quantum gravity help them more to solve the mystery?
Love your videos. I do not have a scientific background. I only got through high school physics 40 years ago, but I enjoy expanding my knowledge of the world in which I live. Question: The inflation idea sounds wild! But, knowing how powerful it was, why did it last for only the briefest period of time? It seems like something this powerful would be difficult to stop.
Dr Alan guth from MIT proposed the inflation theory. In the 1980's . He stated, ( I am paraphrasing. ) the expansion was do to inflation where the forces .Weak and strong were moving faster than lightspeed. He than went to say the reason that inflation only lasted for a short time was do part of light coming into existence. So the reason why inflation didn't break the laws of physics.was light was not in existence. And once light came into existence it put the brakes on inflation.
Don Lincoln says optimistically - "Imagine what we'll know a century from now..". I add rather pessimistically "... if we continue to exist, that is..."
Great use of a scale for a more graphical representation of the quantitative data. Ranges are nice to aid in perceiving systems, even when in fewer dimensions.

Wouldn’t it be more correct to say that the Big Bang is the expansion of spacetime? And as you go back, wouldn’t the increase in energy density cause time to dilate to the point where there never was a beginning? 🤯
Come here to ask this - kind of. At the speed of light and/or beyond, would the time component related to 'Earth seconds' be incredibly dilated? Trying to get my head around this in that at the speed of light, the universe would only be a few hours old from the light photon's perspective. 'Big Bang' was possibly only 'this morning'. Our cold energy that has dropped out of the speed of light and cooled to form matter is basically frozen 'in time' from the photon's perspective. This is way above my pay grade but a fascinating topic to learn about from reliable sources.
You actually just described a black hole! Indeed, a black hole singularity and the Big Bang "singularity" are the exact same idea, for the most part. From our reference frame far away from the super dense region (big bang or black hole), we never actually see the total collapse of objects. So, if we were watching the big bang in reverse from super far away, we would never see everything collapse that far (if that's what actually happened).
ANGRYpooCHUCKER Not the same thing. Black holes don’t expand and all the space of our universe lies within the space of the Big Bang so one can’t observe the Big Bang from the outside.
@@karagi101 That's one interpretation of the big bang, sure. But Stephen Hawking formulated his idea of the big bang singularity by noticing that it behaves awfully similar to a black hole. If you take a bunch of stuff (even the entire universe) and compress it down, you end up with a singularity (or something like it as scientists don't actually take mathematical singularities to mean anything physically). Also, according to some popular big bang models, the universe may in fact be infinite and all of the "stuff" that came from the big bang was just that: stuff. There was still space outside of that region. ALSO ALSO, even if that's not the case, there's nothing stopping us from assuming a reference frame outside of the big bang even if it does represent the entire universe. IF we do assume that reference frame, as Hawking did, then watching the big bang in reverse is identical to watching a black hole form.
Thank you for explaining these concepts in a way that we ordinary folk can understand. I've been watching the PBS videos about space and quantum physics, and I have no idea what the narrator is talking about.
Hi Dr. Lincoln - could you please make a video about the neutron? I'd like to know why it's so stable in the nucleus and why a free neutron outside the nucleus decays with a half life of about 10 minutes?
