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.
True. Some channels think they need background music and it's so annoying.
Edit: I love the intro music though!
Or we can add our own background music at whatever volume we prefer. I like having that power. Talks don't need music.
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, CZcams's text-entry field can't decide which language I'm typing.
I would appreciate the music from Star War. Don don don don don don don don , don don don don don don don don....bon bon

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.
But what about the science?
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 CZcams.
Fermilab is better because it feels like him explaining something to his smart teenage grandkid between shifts at the antimatter factory.
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.
“Scientists admit when they don’t know something...” Best burn today. 🙌🏻🙌🏻🙌🏻
the best burns were in 15th or 16th century when they burned "witches"
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...
@1:41 "Scientists admit when they don't know something" I love this.
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).
I like the fact that he’s wearing a shirt that reference the show called the big bang theory and then has his own show about the Big Bang
Respect the man. He is a professor of high nonsense and can't prove anything he says.
@@kathylynne8872 Why are you watching these videos if you can't even grasp the concept of the scientific process?
@@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.
That's the clearest explanation of the theory that I've seen. So much misinformation out there.
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!
This explanation itself is misinformation. 🙄
@@micahwatson9017 how so?
ERICK PATRIOTA BRASILEIRO plot holes
@ERICK PATRIOTA BRASILEIRO you're funny. I mean, I _hope_ you're being sarcastic.
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.
Dude I love your channel
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 ?
Ya Stephen Hawking also said same
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
But yet, he said the universe May/Perhaps have been infinite at the time of the big bang.
I love your videos! You are an amazing presentator for this, its really interesting and fun to watch!
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.
HAHA, yes!. "(clears throat) giant sphere..."
Flatards triggered!
that was more difficult for him than it should have been. HE IS A FLAT EARTHER :O

Just finished The Theory of Everything. Amazing series of lectures! Pleasantly technical without getting overloaded in calculations.
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
Happy New Year Dr. Lincoln to you and your peeps. Love your content and presentation.
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!
Your presentations are the best that i have seen and heard on (any) subject on the net. THANK YOU
This is the best video from you. Thanks for the video.
This is brilliant. Dr. Don is an excellent story-teller.

== 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).

Dr. Lincoln: "Hold my beer..."

No you don't. Nobody has.
No one has a good grasp of it. The THEORY is nonsense it's a tax payer funded religion
@@michaelking8061 well... at least not a religion, because religions seem to claim absolute truths without evidence.

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.
God almighty said ( Have not those who disbelieve known that the heavens and the earth were joined together as one united piece , then we parted them ? and we have made from water every living thing . will they not then believe ? ) [ prophets : 30 ] .
and said ( And the heaven We constructed with strength, and indeed, We are its expander).[ chapter 51: Verse 47 ]
Those verses from holy Quran before 1440 years told about( The Big Bang Theory ) that we are studying it recently discovered .
God almighty who created all the world he is only one God and he sent prophets and massengers Like Adam Ibrahim Moses Jesus Muhammad etc and revealed to them books like a book instructions of human bieng illustrates every thing we need to know .. Quran is the only book preserved from God from the past until now unlike another books hasn't been preserved .. so who wants to know truth of life he should read Quran to find the truth .
Many muslims are not following instructions of God well like isis or saudia arabia king for example, so do not judge Islam by behave of muslims .. unfortunately also media highlights the bad people in Islam so a wrong picture has been made about Islam .. Islam in arabic means ( submission to God ) .
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.
Thx Don..love your DVDs at this difficult time..be safe tgc
Started watching today ur channel each video is osm . Keep on watching all of m . Can’t able to skip one 😂
You were trying to explain this to people that think the sun is a lamp just above the clouds and the moon emits cold light, good luck.
You and PBS, best channels in the visible internet !!!
@Net Syncs true...but we need the TOR derivation ;)
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
Neither of you can learn any content from this video. It's to unedjumacated.
As always... just great!. Very didactic and easy. Keep up!
As usual, Cosmology blows my mind once again...Thanks, Dr.Don!
You don’t know how long I’ve been waiting for you and Matt O’Dowd to collab on PBS Spacetime
I too was glad that happened, having watched both folks in CZcams.
Great video and great explanations! Appreciate it.
Awww I was touched by what you said at the end. I hope we all get to know the truth of reality & the theory of everything!
Great explanation, Don. Thanks! 50 years reading/pondering this stuff, outdone in 11 minutes! Major... 😁
Dr Lincoln has a fantastic way of explaining things. Thank you.
Your video is just great! Huge respect!
I always enjoy your videos.
Thank you for the answers I was seeking for decades!
Thanks for hitting so many misconceptions in one video.
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.
Thanks. Short and captivating, more importantly it is enlightening. Keep up with the good work.
From Hker worldwide
Dr. Don Lincoln is simply the best explainer of cosmology out there. Always 100%
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!
Thanks for dumbing that down for me. The most educational thing I have watched for a while.
i love your honest admissions and i wish you good health for years to come :)
Thanks so much for posting this. It certainly clarified some of my misconceptions about the big bang.
Don't question the boom or you will be labeled flat earther haha new insult for those that question the popular myth
Neah, he only gave you more misconceptions. Instead take some lessons in using logic. We will then call you Mr. Spock.
10/10 for the shirt choice
Thanks for the videos.
Really enjoyable presentation.
How he keeps shrugging... "Sorry to blow your mind... again."
Priceless!
Love the nod to the flat earthers 👍👏
I would consider it more "Throwing Shade" than a "nod".
A nod implies support rather than derision.
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 !!!
Around these parts a nod would be likened more to a tip of the hat on the way past.. hi>bye
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.
They are still a thing? Thought they all already fell of the edge.
Enjoyed alot
Great explanation
Really looking forward to the potential follow up video on before the big bang.
I liked the subtle difference you revealed about what big bang theory is and what it is perceived as.
Keep making such videos Dr Don.
DR. Lincoln, thank you for clarifying for me what the Big Bang really is.Love your talks.
Exelent video! Congratulations!
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?
Excelente explicação 👏🏻👏🏻👏🏻🎓👨🏻🎓👩🏻🎓
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.
I absolutely enjoy these videos. Thank you so much.
Thanks Don. Really good explanations. Fascinating stuff.
Now, that's what I call a great explanation!
@Henrik Wallin well unfortunately there actually are predictions made based on past theories and real data but you just can't accept that
@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...
Don Lincoln is the best physics lecturer ever ! Thankyou for this.
But, he hasn't said anything that makes logical sense.
Kathy, everything he says makes sense. Perfect sense.
Love this guy's channel. So much more comprehensible than others...
Very informative and high quality.
Q: "What really happened at the Big Bang?"
A: "I don't remember, I was very young back then."
TOO FUNNY. I was born shortly after the big bang.
Keith Richards remembers
Holy cow, did we have a big bang? Sorry I missed it, must have been sleeping.
""I don't know, I was really drunk at the time"
“Big Bang is physics and physics is everything.” So well said!
Curious how is physics everything? How can physics be agent causation?
@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.

Dr. Lincoln, can we get a video about the nature of the inflaton field and it’s role in the inflationary hypothesis?
No, he doesn't have enough information about the hypothesis of inflation.
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.

How can that be
Clearing throat when obviously a giant sphere thank you I love you for that.
underappreciated comment.
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.
great videos
Very good explanation professor. Congratulations. Difficult topic to digest completely. 👏👏👏👏👏👏👏👏👏👏👏
I was there. It really was a BIG bang! Take my word for it....
"Well nobody was there at the time, so we can't possibly know anything"

Strings ARE kind of noodles packed with (sub)nuclear energy.
It's beautiful to be able to relax in an alternative-facts-free zone like this and just let your mind enjoy itself.
mind blown! Thanks again, Dr. Lincoln!
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.
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).
Silo _fx From light’s frame of reference it experiences zero time.
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.
The more I learn about the big bang the less I know about the big bang!
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
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.
