What do you think is the biggest obstacle to achieving controlled nuclear fusion on Earth, and how might overcoming it reshape our future energy landscape?
Material science, if something can withhold something as energy intensive as a fusion reactor, then that material must have been forged with something that produces more energy than the fusion reactor. It's an energy paradox
This Teen Will Revolutionise Nuclear Energy NBC Archives.. the young mans name is Taylor Wilson. He has already shown and built exactly what you are talking about.. This is not a joke, it's right here on TH-cam...it is a must watch. He achieved controlled nuclear fusion when he was 14.
I think the biggest obstacle is two-fold, though related: politics and funding. There are always those who will say, "That money could be better spent on {insert pet project here}." The other part is that large-scale fusion reactor construction will face pushback, similar to nuclear plants. That pushback will be well organized, well-funded, conspiracy-driven and will gather followers. Just look at the expansion of the 5G network and the conspiracy nonsense that emerged out of that.
I appreciate Neil’s existence more than anyone will ever know. I’ve learned from him since I was a kid, and even though it’s been through a screen, he is able to get across so much more than just a science lesson. The way he speaks makes you want to be a better person everyday. I can only hope I’m lucky enough to meet him one day! ❤
It's always lovely and special when someone enters the sometimes sickening world of media with the pure intention of spreading knowledge. Neil feels like that
same, he's always my fave to listen to. :D I try not to think about how old he is, because the thought there's no one close to carry his torch is too depressing for me. GRRM will live for ever and finish his books and Neil will always be here for us.
Neil is indeed a national treasure. I so enjoy every time I hear him speak, and I did get to see him live, but didn’t get to meet him. He’s a lot like my dad, who’s a retired physician and educator, semi-prominent in the ‘90s. But Neil is less intimidating, and seems very approachable and fun-loving.
Neil is a great presenter, making complex issues in astronomy and astrophysics understandable to the layman. He did admirable work in his 'Nova' TV series about the Universe.
He needs a better title than "Lord" since we don't allow titles of nobility in the U.S. Remember, Bill S. Preston, Esquire from _Bill & Ted's Excellent Adventure?_ I guess that means lawyer.

Ok guys. A Major General is a 2 star. Here is the Military acronym for it. "Be My Little General" Be = Brigadier General (1star), My = Major General (2star), Little = Lieutenant General (3star), General = General (4 star). I do know the Army has a 5 star but being a Marine I have no clue what their title is...Maybe General of the Army lol. Hope this helps you out.
5 Star is General of the Army, and 6 Star is General of the Armies, but only General Pershing has held the latter title during his lifetime (both other 6 star Generals were awarded the 6th star as an honor posthumously).
5 stars are only given during time of war. There has not been a 5 star general since Korea (Omar Bradley). It was created, and is used, only to make a US general officer equal to or surpassing equivalent ranks of other nations so as to be in a position to command their forces.
16:40 Be My Little General. It's a mnemonic phrase used to remember the rank order of the 4 types of Generals! Brigadier General = ⭐ Major General = ⭐⭐ Lieutenant General = ⭐⭐⭐ General = ⭐⭐⭐⭐ General of the Army = ⭐⭐⭐⭐⭐ (only issued in times of war)
Re the expansion slowing down, I don't think Neil answered that question satisfactorily to me. He's saying that since we know things farther away move faster, as things currently close to us get farther away, they will accelerate, because we know things farther away are going faster. But do we know that things automatically go faster just because they're farther away? I don't think we can assume that. If we imagine a universe where everything expanded at some speed of 10 in the first billion years, then in the 2nd billion years it all expanded at 9; then 3rd billion 8. If we were were in that 3rd billion, the things within a billion lightyears would be going at 8, but things at 3 billion lightyears away would still appear to be moving at 10. So EVERYTHING is now actually only expanding at 8, but it only appears like things farther away are going faster because it took so long for the light to get to us. How is this not a a possibility?
I agree. Having wondered about this myself I would have liked to have had a more satisfactory answer from Dr Tyson. The light from stars further away takes longer to get to us, so we are seeing them as they were further back in time. That being the case, if they are more red-shifted than closer stars, does this not indicate that space was expanding faster in the past? If not, why not? No explanation was given 🤷
RE: Neil's transporter solution. In Star Trek:TNG there was an episode where they discovered an ancient technology of a long extinct and powerful race where they created gateway portals similar to your wormhole transportation solution. The Iconian Gateway. TNG episode "Contagion". Super cool and elegant solution to star hopping within a galaxy.
You guys could move the setup to the other side of the room for a change? Maybe let Chuck sit at the desk and and ask questions to Neil as a sort of guest, could be a funny vieuw as well @StarTalk
It’s wild that we can now have some of the smartest people on the planet explain mind-blowing concepts to us while we’re in pajamas, eating cereal on the couch. Who knew the path to wisdom would run through our living room Wi-Fi?
If you are labeled a Sergeant you have been given high praise. Sergeants make things happen; just ask any officer in the military what couldn't happen if they lost their NCOs. Air Force aircraft would stop flying and Army adventures to take a hill wouldn't be achieved. In the meantime, Navy ships would sink. Marines: might be okay but they wouldn't grunt as loud because they would be treading water for a long time.
Part of the sergeant's creed: If a corporal tells you he did something on his own initiative, go fix it. If a lieutenant tells you he did something on his own initiative, go fix it.
I would never use a transporter. There's no guarantee anyone could give me that my stream of consciousness doesn't end when my body is ripped apart and the person on the other side continues with no awareness their previous "soul" just died. It would be like going to sleep and a copy of you wakes up, but you never do.
Dude yes! I’m not religious and I don’t believe in a soul, so I think of it another way. Imagine you take the transporter and it glitches out. You step outside of it, wondering why you didn’t travel. But on the other side is another copy of you that did get teleported. That person, although they are you in every way imaginable, does not share a consciousness with you. Therefore, you are two different people. So each time you teleport, “you” die and a new “you” is created.
I thought about this when watching an episode with Barclay (he refused to use teleporters). 1) the risk of malfunction: Everything you do has risks, go outside, drive a car, go to sleep, take a shower, you can only live with 0 risk if you forfeit your life :P 2) you die, and a copy lives on: It does not matter. The old you will not realize it no longer exists, because you no longer are conscious. But everything you learned/done/experienced keeps its value in the form of the new you. So you dont "lose" your life, it merely gets transported :)
I remember the episode when chuck got the lord title, and the next few episodes when it stuck. I did not expect it to last beyond that 1 episode, but I loved it. Such a fun little in-joke.
Hey guys...thanks for all your programs. So...speaking of Fusion reactors. I have always had the question in my mind about the thoughts of the person who pressed the "button" for the first time. That day...when we "believed" we knew what the results must be. There would have to be that "what if" question in the back of your mind..."What if I am wrong and it does blow up the world!" That has to keep one up at night, eh?...smiles.
Your assomption only works if you build a fusion reactor from a recipe book hoping to get more energy back. But fusion reactor cannot be written like a theoretical plan. It's not something you can do in normal conditions of pressure and temperature. It's so technologically advanced and technically expansive it's comparing a kid building a sand castle on the beach and a lot of financiers/engineers/technicians/workers planning then building the Burj Khalifa ; the kid on the beach is your typical fireplace ; the suburban house is your wood/coal/oil domestic furnace ; appartement blocks are electric plants ; the nonsensical skyscraper is the fusion reactor. Nobody thought it was even possible to build skyscrapers this tall not so long ago because of structural tensions, materials, huge mass, heavy wind, etc. The Burj Khalifa is 150m (500 ft) higher than the second highest skyscraper. So, in a sense, if you can invest billions, you can have in a decade your fusion reactor. Not very efficient maybe, but pretty secure. The only danger of this installation is the same as your oil electric plant but with billions in the line if something goes wrong instead of millions.
My dad, who was born in 1923, talked about what a game changer fusion would be all the way back in the 60s. He said, “Someday, we’ll get there. It will solve a lot of problems.” I was just a kid back then, and I only had a vague idea what he was talking about. He is long gone, but if he were still here he would have loved this discussion.
I've been playing Starfield lately and I just can't help but to think they really should put Dr. Tyson in it. Between the two of them, they've really expanded my 'horizon' and opened my mind to the mysteries of space. What a breathless universe we live in, I wish that I could explore it all
The show "For All Mankind" predicted us going back to the moon to harvest Helium 3 for fusion fuel. I found it very interesting that the announcement of the Artemis missions happened right around the time that lab's original announcement of successful contained fusion.
I don’t think most fusion models are planning to use He-3 at all. I believe they mostly use Deuterium and Tritium. There are still good reasons to try to mine He-3 on the moon (even though it’s rly fugging hard to do), namely that it’s worth an absolute megaton of money on Earth for other reasons. Edit- to be clear I’m not entirely sure of this. I just remember hearing it somewhere and briefly researching it to see if it was true.
What a cosmic duo. Man we all need this goodness and we all thank you. Just tried to teach my kids about tiny, little silicates... fail. Rad. Gratitude.
Unfortunately Dr. Tyson has missed the point of a very important question about redshifting. If we see redshifting appearing to be faster in the past (yes, farther away, but in the PAST), and then the closer to our present we observe an object we get a redshift that is slower, then how can you predict that the red shift will change trajectory and speed up in the future? It is on a slowdown trajectory when observed from past to present. My answer, it may be, just maybe, that the quicker redshifting seen in objects farther back in time may be caused by the entire universe's gravity having more time to stretch the light as it travels toward our current space and time, which is why light from closer objects appear less stretched, less redshift, because the light has not traveled as long and the universe's gravity has had less time to stretch the wavelength. In this scenario, redshifting is an optical illusion, and not actually a physical expansion of space. It is caused by the pull of all the universe's gravity on traveling light over a long period of time that becomes less noticeable the closer an object is to our time and space here at Earth. Possibly not noticeable for anything closer than 2.5 million light years, which would be why Andromeda appears as blue shifting.
No there's more red shift and it "moves faster" because the universe expands everywhere at a rate. Over a long enough distance a plus 1 expansion. Will be a plus 1 twice because there's more distance to expand between them.
You know I had a question I asked on on the reddit AskPhysics about gravity and I was not only insulted but demeaned, and it didn't give me much hope for the scientific community. Thank you Dr. Tyson and Lord Nice for doing what you do because I learn many new things thanks to the videos you post. If anyone knows a place where I can ask questions that may seem silly or even down right wrong, please let me know because I DO want to learn but I don't have the time to take a physics class. I was taught classical physics in the early 90's when Gravity was a force and Pluto was a planet. Times change. Also - sometimes it takes people who are not set in their ways when it comes to physics or any science to ask silly odd questions because sometimes they hit on something no one thought about. An outside perspective can often lead to discoveries unless people refuse to even consider or think about it. Many discoveries weren't made by scientists, but by people who asked questions that made the scientists who listened go Hrmmm. Invention begins with asking questions, however impossible it may seem.
My favorite visualization of the expanding universe was in a PBS or BBC or similar science video about the universe. In it, they show a room full of chairs (like a classroom), and the chairs are all moving away from each other at the same relative rate in every direction (X and Y). The chairs don't expand, but the space between the chairs does; also, no matter which chair you sit in, all other chairs are expanding away from you. Unfortunately, I get missed the final conclusion, that eventually the expanding universe will cause some chairs to become invisible to you at your vantage point.
@@sandal_thong8631yeah I’m not sure if the OP intended to phrase it in such a way as to be silly, or if they were trying to think of Avogadro’s number in terms of amu?
First timer here, I was pleasantly surprised at how much I was actually able to understand haha, although there were some parts I had to rewind to listen again , but wow, what a great show, that was fun!
If speed causes time dialation would it be logical to say we are inside a time dialation and as the energy from the big bang dissipates the universe will accelerate?
Everything has very tiny time dilation; time is local. Universe cools as the energy dissipates/radiates. Photons get stretched(redder) when they travel over the expanding spacetime.
Love the science love the humor, especially the reference to the movie Cool Hand Luke with Paul Newman. The line, "What we've got here is failure to communicate", was said by the character "Captain" the head security guy who wore those mirrored glasses. Great movie.
This got me looking into the Planck units properly, and now I have kind of gained an overall understanding of why we're where we're at with theoretical physics. That's kind of huge. I wish science communicators would bring this up a bit more, because it gets glossed over a lot as just "the smallest meaningful unit" or the "pixels of the universe" without explaining that it's where GR and QM both break down in their own ways in respect to each other. Understanding this is the gate to understanding so much more of modern physics, and I feel like it's not touched on enough
I love the chemistry with these guys. They are great hosts, I don’t know how many “Ah ha” moments I had this episode. You guys explain things with the best explanation and examples. Love this podcast!!! ❤😊
At 29:48 we don't know how much mass is in the universe. We can't even see what's on the other side of the galaxy. We also don't know how far the universe extends beyond our horizon.
15:29 his thought makes logical sense though. Since the objects closer to us are closer in time. And they are going slower than the objects further away in distance and time. With only those facts, it would stand to reason that the closer to "now" you are, the slower you are moving.
The process of nuclear fusion is fundamental not only for the energy production in stars but also for the synthesis of heavier elements in the universe. Understanding fusion helps us unravel the conditions that prevailed in the early universe, particularly during the first few moments after the Big Bang, when temperatures and densities were incredibly high. How did the conditions of the early universe facilitate the onset of nuclear fusion, and what implications did this have for the formation of the first stars and galaxies?
I cannot fkn belive that I thought about the wormhole transporter thing many years ago! 🤯🤯🤯I always felt that the showrunners on one of the Trek series' should have re-explained how the transporter works and use the wormhole idea. I had hoped that Discovery would have done that, especially since they had the instant transporters that moved objects across space almost within the blink of an eye.
when neil says all motion is relative and you cant declare that youre not in motion, he's right in a practical sense, but there is, theoretically, an experiment that could be done to declare what a speed of 0 is. shoot a bunch of lasers out from a single point, but in different directions, and somehow measure which ones are travelling out "faster". the "fastest" one is the one moving closest to the opposite direction that you're moving (fastest away from your current location as you measure it continuously). once the light is moving in all directions at the same speed, you're not moving. the best way to explain this is that while you can shoot a projectile at say 1200 feet per second out the back of a car travelling at 1200 ft per second, and watch the projectile simply fall straight down to the ground, light will not behave the same way. light will move at the speed of light relative to the point in space that its in. it doesnt matter if youre moving, that point in space isnt, and the light will move away from that point at the speed of light.
1. If I may, I'd like to disagree with Dr. Tyson when he said that Zeno's Paradox isn't a thing in the real world. May I present Exhibit A: *Radioactive Decay,* which is pretty much the very real-world definition of Zeno's Paradox. 2. Chuck's characterization of an infinite series adding up to a finite number as the *"Finite Containing the Infinite"* is just sheer brilliance. Well done, Lord Nice. 3. I had NO idea Dr. Tyson had a cameo on "Velma". Good to know. I need to catch up on that show. This is one of your best episodes yet. My face hurts from smiling throughout the whole thing.

"Be My Little General" Be = Brigadier General (1star), My = Major General (2star), Little = Lieutenant General (3star), General = General (4 star). I do know the Army has a 5 star but being a Marine I have no clue what their title is...Maybe General of the Army lol. Hope this helps you out.
5 Star is General of the Army, and 6 Star is General of the Armies, but only General Pershing has held the latter title during his lifetime (both other 6 star Generals were awarded the 6th star as an honor posthumously).
The military really does have a acronym for everything. Thanks for sharing
5 stars are rare
5 stars are only given during time of war. There has not been a 5 star general since Korea (Omar Bradley). It was created, and is used, only to make a US general officer equal to or surpassing equivalent ranks of other nations so as to be in a position to command their forces.
@@kg4wwnand Grant and Washington if you include posthumous promotions.
16:40 Be My Little General. It's a mnemonic phrase used to remember the rank order of the 4 types of Generals!
Brigadier General = ⭐
Major General = ⭐⭐
Lieutenant General = ⭐⭐⭐
General = ⭐⭐⭐⭐
General of the Army = ⭐⭐⭐⭐⭐ (only issued in times of war)
Lord Nice = 🙂🙂🙂🙂🙂
Lord nice😂😂
Chuck is a Gem, National Treasure
Man… I have been following this channel a while and didn’t know about the whole Lord Nice situation. Appreciate the story!
Re the expansion slowing down, I don't think Neil answered that question satisfactorily to me. He's saying that since we know things farther away move faster, as things currently close to us get farther away, they will accelerate, because we know things farther away are going faster. But do we know that things automatically go faster just because they're farther away? I don't think we can assume that. If we imagine a universe where everything expanded at some speed of 10 in the first billion years, then in the 2nd billion years it all expanded at 9; then 3rd billion 8. If we were were in that 3rd billion, the things within a billion lightyears would be going at 8, but things at 3 billion lightyears away would still appear to be moving at 10. So EVERYTHING is now actually only expanding at 8, but it only appears like things farther away are going faster because it took so long for the light to get to us. How is this not a a possibility?
I agree. Having wondered about this myself I would have liked to have had a more satisfactory answer from Dr Tyson. The light from stars further away takes longer to get to us, so we are seeing them as they were further back in time. That being the case, if they are more red-shifted than closer stars, does this not indicate that space was expanding faster in the past? If not, why not? No explanation was given 🤷
Perfect timing just as I was looking for something to watch ❤
And chuck nice!?!? 🙏🏼
I love how much Chuck makes Neil laugh
Your podcasts make my days always better, thanks Neil.
God, I cannot express how much joy Neil and Chuck bring me. Better than streets of gold.
RE: Neil's transporter solution. In Star Trek:TNG there was an episode where they discovered an ancient technology of a long extinct and powerful race where they created gateway portals similar to your wormhole transportation solution. The Iconian Gateway. TNG episode "Contagion". Super cool and elegant solution to star hopping within a galaxy.
this was one of my most favourite episodes!!! such a GREAT combo and fantastic podcast
Feels like home watching StarTalk. I'd like this channel to be around for as long as possible.
I was trying to think of how to word it, but you did a beautiful job. Tyvm. ❤
These guys have too much fun! Love it
You guys could move the setup to the other side of the room for a change? Maybe let Chuck sit at the desk and and ask questions to Neil as a sort of guest, could be a funny vieuw as well @StarTalk
Whooo! Daily dose of Chuck and NDT!
This show makes a Geek
My continuously following this show makes me happy
I am really happy whenever you guys drop a video
It’s wild that we can now have some of the smartest people on the planet explain mind-blowing concepts to us while we’re in pajamas, eating cereal on the couch. Who knew the path to wisdom would run through our living room Wi-Fi?
If you are labeled a Sergeant you have been given high praise. Sergeants make things happen; just ask any officer in the military what couldn't happen if they lost their NCOs. Air Force aircraft would stop flying and Army adventures to take a hill wouldn't be achieved. In the meantime, Navy ships would sink. Marines: might be okay but they wouldn't grunt as loud because they would be treading water for a long time.
Part of the sergeant's creed: If a corporal tells you he did something on his own initiative, go fix it. If a lieutenant tells you he did something on his own initiative, go fix it.
I could watch/listen to you two talk all day about stuff. Love the content
I would never use a transporter. There's no guarantee anyone could give me that my stream of consciousness doesn't end when my body is ripped apart and the person on the other side continues with no awareness their previous "soul" just died. It would be like going to sleep and a copy of you wakes up, but you never do.
The video game ‘Soma’ is a good reproduction of this
But you could start an exclusive club on the other side! There are bound to a crapton of you to join soon enough!
Dude yes! I’m not religious and I don’t believe in a soul, so I think of it another way.
Imagine you take the transporter and it glitches out. You step outside of it, wondering why you didn’t travel. But on the other side is another copy of you that did get teleported.
That person, although they are you in every way imaginable, does not share a consciousness with you. Therefore, you are two different people. So each time you teleport, “you” die and a new “you” is created.
@@Feignlander My viewpoint is: "Meh. Close enough."
I thought about this when watching an episode with Barclay (he refused to use teleporters).
1) the risk of malfunction: Everything you do has risks, go outside, drive a car, go to sleep, take a shower, you can only live with 0 risk if you forfeit your life :P
2) you die, and a copy lives on: It does not matter. The old you will not realize it no longer exists, because you no longer are conscious.
But everything you learned/done/experienced keeps its value in the form of the new you. So you dont "lose" your life, it merely gets transported :)
I remember the episode when chuck got the lord title, and the next few episodes when it stuck. I did not expect it to last beyond that 1 episode, but I loved it. Such a fun little in-joke.
Hey guys...thanks for all your programs. So...speaking of Fusion reactors. I have always had the question in my mind about the thoughts of the person who pressed the "button" for the first time. That day...when we "believed" we knew what the results must be. There would have to be that "what if" question in the back of your mind..."What if I am wrong and it does blow up the world!" That has to keep one up at night, eh?...smiles.
Your assomption only works if you build a fusion reactor from a recipe book hoping to get more energy back.
But fusion reactor cannot be written like a theoretical plan. It's not something you can do in normal conditions of pressure and temperature.
It's so technologically advanced and technically expansive it's comparing a kid building a sand castle on the beach and a lot of financiers/engineers/technicians/workers planning then building the Burj Khalifa ; the kid on the beach is your typical fireplace ; the suburban house is your wood/coal/oil domestic furnace ; appartement blocks are electric plants ; the nonsensical skyscraper is the fusion reactor.
Nobody thought it was even possible to build skyscrapers this tall not so long ago because of structural tensions, materials, huge mass, heavy wind, etc.
The Burj Khalifa is 150m (500 ft) higher than the second highest skyscraper.
So, in a sense, if you can invest billions, you can have in a decade your fusion reactor. Not very efficient maybe, but pretty secure.
The only danger of this installation is the same as your oil electric plant but with billions in the line if something goes wrong instead of millions.
My dad, who was born in 1923, talked about what a game changer fusion would be all the way back in the 60s. He said, “Someday, we’ll get there. It will solve a lot of problems.” I was just a kid back then, and I only had a vague idea what he was talking about. He is long gone, but if he were still here he would have loved this discussion.
The genesis of Lord Nice is interesting! I love it and startalk
I've been playing Starfield lately and I just can't help but to think they really should put Dr. Tyson in it. Between the two of them, they've really expanded my 'horizon' and opened my mind to the mysteries of space. What a breathless universe we live in, I wish that I could explore it all
The show "For All Mankind" predicted us going back to the moon to harvest Helium 3 for fusion fuel. I found it very interesting that the announcement of the Artemis missions happened right around the time that lab's original announcement of successful contained fusion.
I don’t think most fusion models are planning to use He-3 at all.
I believe they mostly use Deuterium and Tritium.
There are still good reasons to try to mine He-3 on the moon (even though it’s rly fugging hard to do), namely that it’s worth an absolute megaton of money on Earth for other reasons.
Edit- to be clear I’m not entirely sure of this. I just remember hearing it somewhere and briefly researching it to see if it was true.
What a cosmic duo. Man we all need this goodness and we all thank you. Just tried to teach my kids about tiny, little silicates... fail. Rad. Gratitude.
Dr. Tyson, Emperor Chuck
Great show 👏😩
Unfortunately Dr. Tyson has missed the point of a very important question about redshifting.
If we see redshifting appearing to be faster in the past (yes, farther away, but in the PAST), and then the closer to our present we observe an object we get a redshift that is slower, then how can you predict that the red shift will change trajectory and speed up in the future? It is on a slowdown trajectory when observed from past to present.
My answer, it may be, just maybe, that the quicker redshifting seen in objects farther back in time may be caused by the entire universe's gravity having more time to stretch the light as it travels toward our current space and time, which is why light from closer objects appear less stretched, less redshift, because the light has not traveled as long and the universe's gravity has had less time to stretch the wavelength.
In this scenario, redshifting is an optical illusion, and not actually a physical expansion of space. It is caused by the pull of all the universe's gravity on traveling light over a long period of time that becomes less noticeable the closer an object is to our time and space here at Earth. Possibly not noticeable for anything closer than 2.5 million light years, which would be why Andromeda appears as blue shifting.
No there's more red shift and it "moves faster" because the universe expands everywhere at a rate. Over a long enough distance a plus 1 expansion. Will be a plus 1 twice because there's more distance to expand between them.
Neil needs to watch Kyle Hill's Nuclear Energy series!
You know I had a question I asked on on the reddit AskPhysics about gravity and I was not only insulted but demeaned, and it didn't give me much hope for the scientific community. Thank you Dr. Tyson and Lord Nice for doing what you do because I learn many new things thanks to the videos you post. If anyone knows a place where I can ask questions that may seem silly or even down right wrong, please let me know because I DO want to learn but I don't have the time to take a physics class. I was taught classical physics in the early 90's when Gravity was a force and Pluto was a planet. Times change.
Also - sometimes it takes people who are not set in their ways when it comes to physics or any science to ask silly odd questions because sometimes they hit on something no one thought about. An outside perspective can often lead to discoveries unless people refuse to even consider or think about it. Many discoveries weren't made by scientists, but by people who asked questions that made the scientists who listened go Hrmmm. Invention begins with asking questions, however impossible it may seem.
Chuck is on fire tonight.
It's so charming how much Neil laughs. My mood is genuinely boosted to the stars.
I dunno if chuck should get an honorary PHD at this point but definitely an honorary undergrad degree in physics, heh
"Where does rain come from?"
"The sky."
At least give the guy an Emmy
@@Zyo117he ain’t wrong
Uhhhh no, he can repeat a few popular ideas, that doesn't mean he can do a single calculation right.
My favorite visualization of the expanding universe was in a PBS or BBC or similar science video about the universe. In it, they show a room full of chairs (like a classroom), and the chairs are all moving away from each other at the same relative rate in every direction (X and Y). The chairs don't expand, but the space between the chairs does; also, no matter which chair you sit in, all other chairs are expanding away from you. Unfortunately, I get missed the final conclusion, that eventually the expanding universe will cause some chairs to become invisible to you at your vantage point.
8:15 Fun Fact:There are more atoms of hydrogen in a single molecule of water than there are stars in the entire solar system!😅
Still watching early in the video but I'm so going to use this to mess with my nieces' heads lol.
True, there are two atoms of hydrogen, and only one star in the solar system!
@@sandal_thong8631yeah I’m not sure if the OP intended to phrase it in such a way as to be silly, or if they were trying to think of Avogadro’s number in terms of amu?
🤣🤣🤣
@@Feignlander 2>1
3:22 As a Texan, I can vouch for the accent. Top tier. 😅👌🤠
Nice a new Chuckysode, these are my favorites
I like the other guest hosts better. They don't interrupt so much and Chuck's juvenile attempts at humor are just annoying.
First timer here, I was pleasantly surprised at how much I was actually able to understand haha, although there were some parts I had to rewind to listen again , but wow, what a great show, that was fun!
I always feel a bit better about my general common sense when I hear some of Chuck's answers. Bro just like me fr.
I stay up late getting stuck watching your videos. Very entertaining.
I reckon those aliens at 8:54 could be even more badass if rather than getting hydrogen by drinking water they consumed stars
This episode reminded me of the good ol' days before COVID. Glad you're all back on track! ❤
If speed causes time dialation would it be logical to say we are inside a time dialation and as the energy from the big bang dissipates the universe will accelerate?
No because the expasion of the universe doesn't actually move stuff.
Everything has very tiny time dilation; time is local. Universe cools as the energy dissipates/radiates. Photons get stretched(redder) when they travel over the expanding spacetime.
At first this sounded wrong danny, but yes you're correct. As it is "comoving," it's the distinction of proper and comoving coordinates.
Love the science love the humor, especially the reference to the movie Cool Hand Luke with Paul Newman. The line, "What we've got here is failure to communicate", was said by the character "Captain" the head security guy who wore those mirrored glasses. Great movie.
I need a cartoon starring Chuck Nice voicing “Moe Furry”😂😂😂 @ 35:10.
This got me looking into the Planck units properly, and now I have kind of gained an overall understanding of why we're where we're at with theoretical physics. That's kind of huge. I wish science communicators would bring this up a bit more, because it gets glossed over a lot as just "the smallest meaningful unit" or the "pixels of the universe" without explaining that it's where GR and QM both break down in their own ways in respect to each other. Understanding this is the gate to understanding so much more of modern physics, and I feel like it's not touched on enough
Lord Nice brought his A game this time.
he ballin
Two thumbs up !!!!
These episodes just keep getting better.
I love the chemistry with these guys. They are great hosts, I don’t know how many “Ah ha” moments I had this episode. You guys explain things with the best explanation and examples. Love this podcast!!! ❤😊
I love when Neil starts cracking up, they must have fun every time they record
At 29:48 we don't know how much mass is in the universe. We can't even see what's on the other side of the galaxy. We also don't know how far the universe extends beyond our horizon.
15:29 his thought makes logical sense though. Since the objects closer to us are closer in time. And they are going slower than the objects further away in distance and time. With only those facts, it would stand to reason that the closer to "now" you are, the slower you are moving.
40:53 Lord Nice provides one of the best ways to sum up a topic!
Honestly, never thought about the wormhole thing. Pretty INTRESTING, thanks for the idea
You know I like the episodes where it's just chuck and Neil because there is such a good dynamic
8:20 that movie is Battlefield los angeles
Finite containing the infinite. Great explanation for the Xeno's paradox. This brought back the memories from my math classes.
The process of nuclear fusion is fundamental not only for the energy production in stars but also for the synthesis of heavier elements in the universe. Understanding fusion helps us unravel the conditions that prevailed in the early universe, particularly during the first few moments after the Big Bang, when temperatures and densities were incredibly high. How did the conditions of the early universe facilitate the onset of nuclear fusion, and what implications did this have for the formation of the first stars and galaxies?
19:31 I sincerely appreciate the exchange where NDT is walking Charlie through the logic at 19:30 🌧️
Thanks for continuing to make science/astronomy cool and relevant!
I cannot fkn belive that I thought about the wormhole transporter thing many years ago! 🤯🤯🤯I always felt that the showrunners on one of the Trek series' should have re-explained how the transporter works and use the wormhole idea. I had hoped that Discovery would have done that, especially since they had the instant transporters that moved objects across space almost within the blink of an eye.
"It's the finite containing the infinite" Love it.
This was so fun. Neil and Chuck are such a great combo. The Astrophysicist and the Comedian, I love it 🙂
These two are soooo good together!
when i was born ['56] they were advertising 'everything fusion in 10yrs'. and every year since. i've long since stopped holding my breath...
when neil says all motion is relative and you cant declare that youre not in motion, he's right in a practical sense, but there is, theoretically, an experiment that could be done to declare what a speed of 0 is.
shoot a bunch of lasers out from a single point, but in different directions, and somehow measure which ones are travelling out "faster". the "fastest" one is the one moving closest to the opposite direction that you're moving (fastest away from your current location as you measure it continuously). once the light is moving in all directions at the same speed, you're not moving.
the best way to explain this is that while you can shoot a projectile at say 1200 feet per second out the back of a car travelling at 1200 ft per second, and watch the projectile simply fall straight down to the ground, light will not behave the same way. light will move at the speed of light relative to the point in space that its in. it doesnt matter if youre moving, that point in space isnt, and the light will move away from that point at the speed of light.
It's so wholesome watching Chuck make Neil giggle, he is hilarious.
Those fan questions really blew me away!
The two are comedy gold, we need more episodes, this will be legendary till the universe freezes out.
hard to imagine a more dynamic duo
1. If I may, I'd like to disagree with Dr. Tyson when he said that Zeno's Paradox isn't a thing in the real world. May I present Exhibit A: *Radioactive Decay,* which is pretty much the very real-world definition of Zeno's Paradox.
2. Chuck's characterization of an infinite series adding up to a finite number as the *"Finite Containing the Infinite"* is just sheer brilliance. Well done, Lord Nice.
3. I had NO idea Dr. Tyson had a cameo on "Velma". Good to know. I need to catch up on that show.
This is one of your best episodes yet. My face hurts from smiling throughout the whole thing.
4:12 After years of star talk Chuck has the answers before the questions.
Love the show. Chuck's neumono...better known as *coughs* joke is so great.. I love learning new topics when 2 enthusiasts are talking.
