Nice episode, but a bit inaccurate. Heavy elements are not made when a star dies, they are made when two neutron stars collide.
This is an excellent story that you have just told in your video. You are a good story teller. I have three questions: 1. Why is there something, rather than nothing. 2. What would it take, what kind of machine (supposing that we have enough energy for the machine) would it be that could use alchemy to make the Replicator on Star Trek? 3. If there was a Supernova that happens nine billion light years from earth, and a high energy photon and a low energy photon gets thrust towards earth at about the same time, and nine billion years later (a few years ago), they both arrive at earth at approximately the same time; well, wouldn't that mean that space is empty? If empty space truly consisted of particles winking in and out of existence, wouldn't that cause the two particles to arrive at different times? I ask this third question because this is exactly what happened, as proven by Fermi Lab. And, if space is truly empty, then why are there still physicists teaching that space is not truly empty, and that particles do wink in and out of existence? I'm sure that I just have a lack of understanding about what that Fermi Lab experiment actually meant. So, I decided to ask you. Somehow I know that if I ask you, that I will actually understand the answer, no matter how complicated it is... Thank you. 🙂
That is one great storey and told so well. Things make much more sense when they are broken down and explained in layman terms that even I can understand. Thank you so much for your efforts to educate us mere mortals in the ways of the universe. Another greeting from New Zealand.
The vehicle definitely matters when you are stuck in a traffic jam, do you have a/c, is it a stick shift, is it a Rolls Royce? All these factors matter
So, apparently, the cheese molecules which tickle the sensibilities of my nose molecules are more complex than I realized. Wonderful!
Cool video again. I'll oblige; why is there something rather than nothing? More specifically, why are there quantum fluctuations rather than no quantum fluctuations?
Thanks for taking the bait! I've added the question to the list...
Well done Paul!
Nice work and interesting physics and chemistry lessons.
You even answered the title question of "Where does everything come from?":
Simple, a fireball duh.
I appreciate your videos and want to see more. One question I have is where did the energy come from that caused the heat of the big bang to reach 1 billion degrees?
Hi Sir, I have a simple question. Inside a factory at the end of the shift a supervisor and his co-worker are counting the produced objects, the objects are approximately the size of a tennis ball. It is their daily routine,the worker counts the objects as he takes it from the production lot and puts it inside a bag. The role of the supervisor is to keep watch so that there is no mistake while counting. One fine day, before starting the counting process, the supervisor looks at the lot and writes down some random three digit number as quantity of the produced items, in short he assumes that the actual quantity would probably match with that number. Now the question is what are the chances of that actual quantity matching exactly with that random number?
1/999 would be a good guess if the factory ever produced only one thing in a day before...
But, why do you want to compare a random number about 'quality' to the actual 'quantity' number ??
Sorry, correction done.
Good job.
My god man where have u been hiding, I love your content, it brings me peace and relaxes me. Are you a teacher? It's kinda like a bubble expanding to the point it bursts and all the splatter created the universe and you could argue since we were first very hot that it emitted a light like no other and could in the beginning there was light, God opened his eyes.
10:00: In the beginning, Lord Squeak created Cheese. And everything was Cheese! But the Pesky Lord Miau opposed Lord Squeak and the Cheese sank down. Earth was formed.
Good morning Dr. Sutter 😊
Your videos are fun
What a brilliant explanation of a complex idea. Just love Paul Sutter's videos. I have a possible question for him for a future video. It relates to the fact that my paltry brain just can NOT accept that nothing existed before the so called Big Bang. I just can not accept that there was no prior existence before 13.8 Billion years. Intuition tells me (flawed as it is without evidence) that the universe in some form has always existed and didn't just fly into being in a singularity. I don't deny that the singularity and state of affairs Paul describes in this video likely happened - but I wonder if it wasn't part of some greater continuity that has always been in process. Anyway - that's my offering for a future topic....
At what point does the symmetric become random? Or , at what point does the random become symmetric?
.. as a German Biologist -
I was fascinated by this from my early teens on
and studied Chemistry and Biology, Biochemistry...
Now
I am more darkened by the image
of how we end ourselves
Self Titanick

In the end, all species end themselves or are ended by events. Don't get too pessimistic about climate change. Some of us will survive to evolve into some other version of hominid, or maybe be ended by a huge space rock colliding with the earth again sometime. What climate change may well do, is to end our current systems and arrangement. For half of the last 500 million years, the earth was much warmer than it is now - as much as 6 degrees C above the current mean planetary temperature.
" It was a dark and stormy night......."
Evening (its the UK here) I wonder if there is a relationship between the constants we know of, such as G, C, the Plank length etc, and the baryonic mass of the Universe. I wonder if there is a way to use what we know, mathematically, to give us a better insight into the makeup of the whole?
Total mass is no constant
@@mikolajtrzeciecki1188 I didn't say it was. 🥴
I'd like to ask you this question: When a photon travels slower than light speed in water or other medium, Does it experience time since it no longer is traveling at the speed of light? And if so would it decay into some other kind of particle if given enough time at slower than light speed?
Great question! You may enjoy this classic episode: www.pmsutter.com/shows/askaspaceman-archive/2023/6/6/aas-201-how-does-light-slow-down
@@PaulMSutter Ok so the original photon doesn't actually slow down it just takes it longer to get through the material because of all the interactions? So I guess my question now is if a photon could actually slow down would it experience time and decay into a more fundamental particle? Or does that not even make sense because light can never actually slow down?
@sinebar Basically no, a photon does not experience time. I'm sick and don't have the energy, but I can give some pointers. One of the great many TH-cam physics channels besides Paul's is FermiLab with Don Lincoln. It will be a bit of a search, since they have produced a huge amount of video's. But on his channel there are video's about what happens when light slows down in another medium and also video's about the photon's experience of time. You have a good question, sorry I can't give more.
As for the decay, simplifying it a bit, but less speed means less energy, meaning less ability to do stuff. Think of energy as bookkeeping. Before and after the numbers need to match. There's nothing for a photon to decay into. In particle accelerators such as the LHC at CERN, we put a lot of energy into particles so that they have a lot of options for other stuff to decay into. The universe likes to be lazy, find a ground state at low energy. What we see around us in every day life, is there and remains there because it's in a low enough energy state to not do anything that would cause it to cease to exist.
Another amazing video. Thanks Paul. Greetings from New Zealand
Stephen King has a great origin mythology in the book IT. Spoilers, and in very short, there was an ur-turtle. Then it got unwell and threw up the universe. So far, no one has disproven the possibility of an ur-turtle vomiting up the big bang. So it's still possible. Technically. :P
For me mythology was only pretty boring stories and not real or true, in school I wasn't interested in mythology, 2ww was my stronger side and was more interesting for me but now it's good to getting know and learning new things that I and everyone didn't know. Hello from Poland 🇵🇱
Since when is ammonia, an element?
There are hundreds of scientific "Creation stories" besides the physical one. We have the "creation" of continents and oceans, which derives from "creation" of interstellar water and interstellar silica dust, via the creation of the solar system. We have the "creation" of life at some time in the Archaean, and we have "creation" of eukaryotes. We have "creation" of the mammals, the hominids, the humans and the human civilization. One difference between religious and scientific creation stories is that religious creation stories compete with each other and try to deny the other's existence, while scientific creation stories all refer to each other in a vast network of stories that almost never ends. You can easily learn one single creation story but in the religious world that's "the only one," and there is nothing more to learn. In science you learn more and more all the time.
Talk about the plank era through to inflation
You are allowed to stop asking this
nerve-wracking question about the
origin of everything.
IT'S FROM ME.
So, relax.
Turn to the beautiful, noble and exciting
things in your life and be happy.
I personally take care of it, I have
always and I will always take care of
the question of the origin of everything.
EVERYTHING COMES FROM ME.
The serious boundary to Humans understanding consciously, is it is being controlled by ?
I'm hearing creation and can't count out the Tree, Flower, Fruit and Seed of life, these are certainly another story all by themselves don't you think? The Fu Dog has his paw on the Flower of Life so we get a good look at it, it's described as the wheel within the wheel with all those eyes in the Bible and within it's living geometric constructs is time itself from the Zodiac @ 12x30 equals 2160 years for our precession as well as the speed of light from the great pyramid and even the spiders web of dimensional geometry. Maybe for an addition in a series of programs God's geometry of creation could be highlighted? ❤. 🌼🔥🕸️❄️
@timelapse....wat you sayyy....is true ! ....but heavy elements are also created from " Pure Energy Deviation "e.g. when pure "GOOD " energy instantaniously turns 2 pure "EVIL" energy the by product of that are the creation of the heaviest elements in our universe...
Unfortunately there is no electron or proton. We never detected them. We have not even seen an atom
BBT crafts the math of what is believed to be fact, not what is observed. I.e., not objective. As you say, it's a story. Why not talk about the observable universe as a black hole where the collapse is "the beginning". You already have the key ingredients for hydrogen. So you don't have to make up stories. I.e., no puzzles about anti-mater, or errors of 120 orders of magnitude. etc. etc...
You get the homogeneity and symmetry breaking and the four fundamental forces... but... this is where it needs quantum gravity. What's that? What's time? What's mass? What's length?

and stars r us.....errrmmm....i mean toys r us 😋
There is no origin. There is no ending. Let’s get with the program.
The Truth is JEHOVAH God created time, space and matter. He created his son The Alpha and Omega - Jesus, who then came to earth and died for us. He was raised 3 days l8ter (historical fact).

Fact: The Hitchhikers Guide to the Galaxy tells us "Many races believe that the creation of the Universe involved some sort of God, though the Jatravartid people of Viltvodle VI believe that the entire Universe was in fact sneezed out of the nose of a being known as the Great Green Arkleseizure."
Nah. Religion is just the origin of hate, since religious people always attack other people for not falling to their delusions. Religion is just an obstacle to world peace.
u have not explained at all where everything come from.
Most things come from China.
