I rarely ask the AI anything! A couple of months ago I asked AI "can scientists prove" that the big bang didn't happen just once! But a million times, a billion times, endless times! The AI answered me that it was an interesting question and gave extensive scientific data and finally concluded that we cannot know! What do you think? ☺️

I think the best comedians are the ones who will tell you about all these weird little things that not everyone knows about but are still culturally relevant. Especially if they only reveal them one at a time so that it takes a while to realize how much stuff they actually know about.

Just to be clear for anyone wondering. North and south polarity are naming conventions. Historical South magnetic pole = north polarity Historical north magnetic pole = south polarity However, if you have a compass needle that points to the Historical North Magnetic Pole ( which is the South Polarity Pole ) you could arbitrarily say that the needle is of south polarity and thus it is pointing to a north polarity pole, therefore the Historical North Magnetic Pole becomes of North Magnetic Polarity. All these are arbitrary naming conventions.
Thank you! I was going to comment but found your reply and it's spot on. North is just a term to indicate direction with nothing to do with polarity. The compass is a tool. If the magnetic pole flipped tomorrow we would just start painting the other end of the needle. North would remain in its traditional location.
It's actually incorrect to say a compass points north. It points *both* north *and* south. So when the magnetic poles flip, the compass will still be pointing north and south. This is why the N/W/E/S directions are not printed on the spinning bar but the perimeter of the compass body. As it wouldn't matter which direction the polarity is, as long as the bar faces both magnetic north and magnetic south the cardinal directions are still maintained
I can only imagine the things that will be discovered in the next 1000 years. What's nearly impossible for us will be quite simple for those humans. Great episode also 👍. History will remember your work

What I love about the frontier of knowledge is, we have questions. Once that question is answered after we developed instruments to find out the answer, another question pops out of that answer.
Have heard it described as a balloon. What we know is inside. What we don't know is outside. The questions we have are the membrane. The more we know leads to more questions to ask, which makes us realize how much more we don't yet know.

Thank you so much to communicate and explain the scientific method!

A couple of thoughts from me though, The Big bang Theory TV series I believe brought people closer to science that is after all not that boring but instead can be very exciting. Question here, I know I'm not an exclusive member just yet (though considering), regarding the Big Bang that was confirmed and widely accepted, in the process, has it been "investigated" what caused it in the first place? If you could tell in percentage points at what percentage scientists "focus" on answering the how and the why, such as 50-50? The reason I'm asking is that I've worked in improving in many different fields and surely the first step to understand the how, but my favourite is still the 5 Why, to find any root cause for any plausible cause. Shall we focus on the why the big bang happened? What chemical or other actions-reactions resulted to we all be here today? Being an Atheist myself this could probably clear the GOD question as well for many people. Thanks and Peace
You realize no one knows that right? What caused the Big Bang (if there was such a thing) implies a cause, a trigger, a before. Imagine waking up in a car not knowing where you are, going 100 down the highway, and from looking out the window for one minute, you are asked where you "started" your trip a month ago. You don't know what country you're in, what a car is and why you are in the back seat with no driver. Some say God is driving, others insist it's Mohammed or Yahway or Bob. This is why I'm an Atheist, nature is too amazing to make up stories. No one knows what happened and there is no reason to think we should know.
I keep coming back to the question of the plausibility of the big bang being the result of the formation of a black hole... At the moment of the collapse, a big bang event occurs specifically within the black hole.
Excuse me if I’m repeating a previous question, but the images from the James Webb telescope are observational facts that need an explanation.

James Webb is a tool that helps understand our universe.
I'm an eagle scout and very into orienteering, I use compasses a lot, I always thought they just labeled the south pole of the magnet in the compass as north
The South Pole of the needle points North. It’s not labeled North because it’s the North Pole of the needle, it’s labeled North because it orients based on the North Pole. Neil lost it on that one.
Great content as usually, HOWEVER (I want you to hear the Neal way of saying and moving his hands at the same time ) If you can show that the way the measurement was done was flawed in some way, then naturally to data gathered from those experiments are more or less flawed, thus it is possible to change "existing physics". HOWEVER, for the most parts many of the measurements done are quite robust :D
you missed the point that "experimentally verified science" doesnt get undone or thrown out when new ideas come along. If the experiment was found to be flawed in some way then it would be not have been "experimentally verified science".
You are correct sir! Didnt think it that way. I was more just pointing out untill the flaw was found it was declared as such -> it makes objective truths. And when the experimental verified science turns out flawed more or less of the objective truths can/will change. The way NTD implied here was that what we allready established objective truths cannot be undone. But one last point. English isnt my first language so I might have understood that part incorrectly.
@@healdiseasenow No, of course I don't believe it, it's actually a serious crime against children and anyone who does it should be held accountable in court! Don't tell me that he proposed that, he represents, they agree with that? I don't follow him regularly, but if I sometimes hear his opinion about the universe, physics, etc., he's nice to me and he explains it from the heart! But if he supports that small children can change gender, it is unacceptable! It's like tattooing a five-year-old child all over his body because he's "cool".
Wow @StarTalk I can't believe you didn't mention the magma extrusion where seafloor spreading at divergent plate boundaries happens. When lava is extruded at any mid-ocean ridge, the rock it forms becomes magnetized and acquires the magnetic polarity that exists at the time the lava cools. As the crust moves away from mid-ocean ridges, it contains a continuous record of the Earth's changing magnetic polarity. What I find cool is that they can get a pretty close approximation of how often the polar shift has happened in the past.
enjoyed your thought on science. I would question that anything in science is proven. science seems to say that which is most likely. we seem not to know anything with certainty only that which is most probable. science as all else in the universe is evolving and possibly without direction such as Darwinian evolution. as you stated, science is constantly questioning existing knowledge. this is healthy. whish other aspects of humanity would do the same. thank you for comment.
And some people see that science being progressing towards the truth of reality as a bad thing. Those people are science deniers, and they are constantly strawmanning and ridiculing the fact that in science it's ok not to know something, and that theories can change with new data. These naysayers live in a static mindset where all they can do is accuse others of not being "open minded," on the basis that their claims about reality are unconvincing and unscientific. It's sad.
Mr Tyson, sir., you are one of those people that i have respect for without any backthoughts. Can you please explain to me how our planets (Earth) core works? There seems to be a lot of information regarding it but it seems there is more information on all other planets and starts rather than our own planet. How does our planet core works, is it iron and rotates counter clockwise? Thank you sir! Best regards, Peter K.
If we are being visited by aliens advanced enough to travel across the galaxy, they probably think it’s hilarious that we are stuck at the Big Bang Theory and haven’t figured out everything about the universe lol. “They don’t even know what Dark Matter is!” 😂
Bees have the ability to see ultraviolet light. Dogs are unable to perceive colors, so maybe it is possible that humans are unable to detect additional spatial dimensions, similar to our initial inability to discern various types of electromagnetic light.
I've got this sci fi idea i like regarding the Big Bang where what happened was the universe is actually cyclical in the sense that what ends up happening is that sentient life inevitably develops and in its inherent need to fight each other inevitibly ends up in the development of a weapon capable of releasing so much energy that it leads to the destruction of the one universe and the creation of a new one.
Could very well be cyclic for no purpose at all - regardless of what shenanegans we're up to. Certainly, we won't be around next time, so throwing some sort of pre-determined human action into the equation it's like introducing an un-necessary complication of the theory.
@@thatdudeinasuit5422 Yeah. But, it doesn't really matter what kind of idea it is - it's a quite interesting thought even if it just explain how Universe started THIS time.. :-)
Chuck is the luckiest guy ever to have a partner like Neil on a day to day basis. He’s hilarious and the perfect compliment to Neil, a human super computer.
What if the universe was once 4-dimensions, but collapsed to a single point? And the Big Bang of the 3-dimensional universe is what we observe as that collapse of that extra dimension?
Expansion theory is based on assumption that the speed of light is constant and when you look at light from long, long way away, it should be red shifted only if it’s moving away from you, which is all dependent on The speed of light being constant, which we can’t prove.
Tyson is great, but lately I’ve been appreciating Chuck more and more. He’s so perfect in his role in this show. His face, his eyes, his expressions-all show genuine wonder and curiosity. The fact that he’s so easy on the eyes doesn’t hurt his likability either! Did I spell that right? It looks like it says lick-ability, which may or may not apply, according to your preferences!
Please answer my these questions: 1) we know that before the "big bang", all the mass was present at a single point , and the temperature and pressure of that point was infinite. So the question is if there was some temperature (suppose x) then the particles would've vibrated and if the particles vibrated then their must be some space. 2) If the particles vibrated, this means motion occured which means there was some time in which it occured. But acc. To this theory the time was t = 0, before the big bang So this means there was both space and time before the big bang. And if someone has answer to my question, then please reply
Nothing is simpler for explaining the beginning of life, consciousness, space-time, and everything else than "one."
The very meaning of "quantum" is the reduction of physical terms, like centimeters, to rational-numbers-only by cancellation of terms. obeying the rules of abstract math while respecting the hidden identities therein.
The founders of our country were Deists, who believed that the universe is like a clock set in motion that unwinds to its ultimate conclusion.
In quantum dynamics,50:50 (division into two) is the most probable "resonator" in mathematical theory; also explaining the origin of the universe from unity. Every positive prime number thereafter is a resonator of increasingly lesser probability.
Trying to imagine the cause of the initial unity forming "us" is the domain of religion and faith, not science.
The past has everything to do with the course of the future. The past be truly known, humans would not be doing what they are currently doing to this planet.
Emergent consciousness means that the universe is designing itself. changing the course of the future. "Where there is the will, there is the way." That is all about "knowing."
In one high school advanced physics class, the first semester was basically Newton's physics. Then second semester, we were told that Newton was wrong and subsequently was taught about vectors and then moving up to the basics of Quantum Mechanics or some of Einstein's Theory of Relativity. Even in college in my Physical Chemistry class, (a requirement for Chemistry majors, I have a BA in Chemistry) was told the same thing about Newton being wrong. In my head, since high school physics, I thought something was wrong about these statements about Newton's Laws. Newton's laws cannot be totally thrown out the window. He was right on a lot of points. The first and second law apply to the quantum as well. I thought to myself. And Newton's Laws work...to a point. I didn't understand why people would want to throw Newtonian physics totally away. This Startalk video is the very first video that helped put my thoughts together. Einstein's Theory becomes Newtonian Physics for low speeds and low gravity. I was amazed how that clicked with my unease about throwing out Newton and his Laws. 😅 Newton was seeing only part of the picture of the universe, Einstein did not debunk Newton, he included Newton's proven laws in his wider view of the universe. That makes me think of singularities and dark matter and dark energy. First singularities: Einstein's Laws completely break down at the singularity point. Some scientists say tbey do not exist. Do they not exist just because we seem to have run into a roadblock? Or is there evidence in the equations and/or the outside world that suggests that singularities do not exist? Same with dark matter ( and energy) are they thrown into equations like the "planet" Vulcan was? Or is there rational mathematical and/or real evidence that it (they) fundamentally exist?
Ever since he mentioned what happens when the magnetic poles flipped and then why we need a magnetic field my brain was constantly going "so what happens to solar winds that travel toward the planet when the magnetic field is zeroed out?". He glossed over it in the end but I think it would be interesting to have a detailed descussion on that.
I’m curious about the magnetized portion of the core. Can the portion of the core that is hotter than the Curie temperature be magnetized? (Maybe the Curie temperature is higher with pressure?) If not, then the magnetized volume would be near the interface bet the core and the crust (or mantel). Also, temperature would be part of the complex dynamics of magnetic pole movement.
William Herschel, an astronomer best known for discovering Uranus, made significant contributions to astronomy, including the discovery of infrared radiation. His work required foresight in terms of developing innovative observational techniques and equipment, such as his large reflecting telescopes, which enabled him to explore the cosmos in unprecedented detail.Comparing foresight between William Herschel and Neil deGrasse Tyson is a bit challenging as they operated in different eras and contexts. Herschel's foresight was crucial in advancing observational astronomy during his time, while Tyson's foresight lies more in his advocacy for science education and public engagement with scientific ideas instead of actually making any groundbreaking discoveries.
I was always curious about those sheets on the bottom of the JWST. I thought they were solar sails but that didn't seem to make much sense as far as efficiency goes with them blocking each other. Thanks for clearing that up for me!
I knew the JWST had sun shields, but i didn't realize that it also actively cooled it. I said "That's wild! just a few seconds before you guys did, too 😂😂
It quite mind-boggling to realise that all the objects we see don't have colour & that the colours we do see originate from the light reflected from them. This discovery helped me understand why night vision equipment always displayed images in variations of grey. I imagine eventually that someone will invent a display unit that does show the colour of objects at night by way of artificially colouring the images we see via night vision equipment, maybe it already exists but just isn't available for public consumption at the moment?
i think the cycle universe theory makes the most sense to me, the universe expands and collapses back into a big bang forever continuing a never-ending cycle. but who am I to say what makes sense...
It's a bit like trying to create a baby by crushing an adult- sorry for the unpleasant analogy, but the universe similarly grew with a series of development stages, you can't simply reverse. Hawking's cyclical model had us literally crawling back inside the womb- I think it's as absurd as it sounds, anything to get around a singular creation event.
@@SteveLomas-k6k it makes no sense if the universe only existed once roger Penrose suggested that the universe in the far future has the same properties as a big bang
9:30(ish) - i just realized the link between "F=ma" and "e=mc²"...Force and Energy are kinda similarly defined, equals mass, times how fast something is moving (capped at Speed of Light)
Could the Big Bang just be a small piece of a bigger theory?

"WTF" is a highly technical term only uttered in the most perplexing of experimental situations.
I'm an eagle scout and very into orienteering, I use compasses a lot, I always thought they just labeled the south pole of the magnet in the compass as north
The South Pole of the needle points North. It’s not labeled North because it’s the North Pole of the needle, it’s labeled North because it orients based on the North Pole. Neil lost it on that one.
@@JosephRNalbone okay yeah that's what I thought, that really confused me when he said that
Great content as usually, HOWEVER (I want you to hear the Neal way of saying and moving his hands at the same time ) If you can show that the way the measurement was done was flawed in some way, then naturally to data gathered from those experiments are more or less flawed, thus it is possible to change "existing physics". HOWEVER, for the most parts many of the measurements done are quite robust :D
you missed the point that "experimentally verified science" doesnt get undone or thrown out when new ideas come along. If the experiment was found to be flawed in some way then it would be not have been "experimentally verified science".
You are correct sir! Didnt think it that way.
I was more just pointing out untill the flaw was found it was declared as such -> it makes objective truths. And when the experimental verified science turns out flawed more or less of the objective truths can/will change. The way NTD implied here was that what we allready established objective truths cannot be undone.
But one last point. English isnt my first language so I might have understood that part incorrectly.
Neil Degresse is brilliant mind, amazing human being and I agree with him in most theory ..98% 🙏
Do you believe little children should change their genders because they heard you could do this at school
@@healdiseasenow No, of course I don't believe it, it's actually a serious crime against children and anyone who does it should be held accountable in court! Don't tell me that he proposed that, he represents, they agree with that? I don't follow him regularly, but if I sometimes hear his opinion about the universe, physics, etc., he's nice to me and he explains it from the heart! But if he supports that small children can change gender, it is unacceptable! It's like tattooing a five-year-old child all over his body because he's "cool".
@@healdiseasenowIs that all you argue about? Argue something *important*
@@NewYork-hi6zdNo, he never said anything like that.
@@MagicToenail I'm glad to hear that 🤗
6:50 like Einstein & Newton. Einstein didn't prove Newton *wrong". He refined our understanding of how gravity worked.
Wow @StarTalk I can't believe you didn't mention the magma extrusion where seafloor spreading at divergent plate boundaries happens. When lava is extruded at any mid-ocean ridge, the rock it forms becomes magnetized and acquires the magnetic polarity that exists at the time the lava cools. As the crust moves away from mid-ocean ridges, it contains a continuous record of the Earth's changing magnetic polarity.
What I find cool is that they can get a pretty close approximation of how often the polar shift has happened in the past.
_"I went searching for the universe and all I found was me._ " Funny and profound!
Thank You guys so so much. I Love you guys more than you will ever know. Keep making my day over and over again. Thank you.
Science constantly questions existing knowledge and builds upon what is already proven.
enjoyed your thought on science. I would question that anything in science is proven. science seems to say that which is most likely. we seem not to know anything with certainty only that which is most probable. science as all else in the universe is evolving and possibly without direction such as Darwinian evolution. as you stated, science is constantly questioning existing knowledge. this is healthy. whish other aspects of humanity would do the same. thank you for comment.
And some people see that science being progressing towards the truth of reality as a bad thing. Those people are science deniers, and they are constantly strawmanning and ridiculing the fact that in science it's ok not to know something, and that theories can change with new data. These naysayers live in a static mindset where all they can do is accuse others of not being "open minded," on the basis that their claims about reality are unconvincing and unscientific. It's sad.
Neil and Chuck are so brilliant together.
I recently discovered StarTalk... I can't stop watching the episodes 😶
Amazing explainers, as always. Thank you!
I ❤ Chuck!😂
Welcome to science dome
This is absolutely joyous! Thank you 😊😂
Mr Tyson, sir., you are one of those people that i have respect for without any backthoughts. Can you please explain to me how our planets (Earth) core works? There seems to be a lot of information regarding it but it seems there is more information on all other planets and starts rather than our own planet. How does our planet core works, is it iron and rotates counter clockwise? Thank you sir! Best regards, Peter K.
How much I love these two. Thank you , kind sirs, for spreading the light. Indebted🙏🙏🙏
I came before the big bang. If you don't believe me, just ask my wife.
BudumpPsh😂 exwife?
21:23 🤔 anyone else pick it up 😂
If we are being visited by aliens advanced enough to travel across the galaxy, they probably think it’s hilarious that we are stuck at the Big Bang Theory and haven’t figured out everything about the universe lol.
“They don’t even know what Dark Matter is!” 😂
Bees have the ability to see ultraviolet light. Dogs are unable to perceive colors, so maybe it is possible that humans are unable to detect additional spatial dimensions, similar to our initial inability to discern various types of electromagnetic light.
So Awesome how you and Chuck ping off each other, making important scientific topics fun. Appreciate you guys!
21:35 best moment 🤣🤣
0:01 Mike check, testing 1 2 3, thump thump thump, screeeeeeechhh. Mike check.
I've got this sci fi idea i like regarding the Big Bang where what happened was the universe is actually cyclical in the sense that what ends up happening is that sentient life inevitably develops and in its inherent need to fight each other inevitibly ends up in the development of a weapon capable of releasing so much energy that it leads to the destruction of the one universe and the creation of a new one.
Wow, what a tragically dumb fate that would be. I hope it isn't true, lol.
Could very well be cyclic for no purpose at all - regardless of what shenanegans we're up to.
Certainly, we won't be around next time, so throwing some sort of pre-determined human action into the equation it's like introducing an un-necessary complication of the theory.
@@D.Appeltofft did you read the "it's a Sci-Fi idea" bit? You know the first 5 words of the post. 😒
@@thatdudeinasuit5422 Yeah. But, it doesn't really matter what kind of idea it is - it's a quite interesting thought even if it just explain how Universe started THIS time.. :-)
Chuck is the luckiest guy ever to have a partner like Neil on a day to day basis. He’s hilarious and the perfect compliment to Neil, a human super computer.
Thank you for this Neil
What if the universe was once 4-dimensions, but collapsed to a single point? And the Big Bang of the 3-dimensional universe is what we observe as that collapse of that extra dimension?
Nope
I think Karen would disagree. The universe clearly revolves aroune her!!! and she wants to see your manager NOW!!!!!
Brilliant and interesting
Tyson explains concepts so clearly and easy to understand
And makes it interedribf
Expansion theory is based on assumption that the speed of light is constant and when you look at light from long, long way away, it should be red shifted only if it’s moving away from you, which is all dependent on The speed of light being constant, which we can’t prove.
Tyson is great, but lately I’ve been appreciating Chuck more and more. He’s so perfect in his role in this show. His face, his eyes, his expressions-all show genuine wonder and curiosity. The fact that he’s so easy on the eyes doesn’t hurt his likability either! Did I spell that right? It looks like it says lick-ability, which may or may not apply, according to your preferences!
Please answer my these questions:
1) we know that before the "big bang", all the mass was present at a single point , and the temperature and pressure of that point was infinite. So the question is if there was some temperature (suppose x) then the particles would've vibrated and if the particles vibrated then their must be some space.
2) If the particles vibrated, this means motion occured which means there was some time in which it occured. But acc. To this theory the time was t = 0, before the big bang
So this means there was both space and time before the big bang.
And if someone has answer to my question, then please reply
Nothing is simpler for explaining the beginning of life, consciousness, space-time, and everything else than "one."
The very meaning of "quantum" is the reduction of physical terms, like centimeters, to rational-numbers-only by cancellation of terms. obeying the rules of abstract math while respecting the hidden identities therein.
The founders of our country were Deists, who believed that the universe is like a clock set in motion that unwinds to its ultimate conclusion.
In quantum dynamics,50:50 (division into two) is the most probable "resonator" in mathematical theory; also explaining the origin of the universe from unity. Every positive prime number thereafter is a resonator of increasingly lesser probability.
Trying to imagine the cause of the initial unity forming "us" is the domain of religion and faith, not science.
The past has everything to do with the course of the future. The past be truly known, humans would not be doing what they are currently doing to this planet.
Emergent consciousness means that the universe is designing itself. changing the course of the future. "Where there is the will, there is the way." That is all about "knowing."
I really wanted to hear Chuck's version of how infrared was discovered.
Scientific question…when are you two going on a tour? Please include Atlanta.
Chuck is definitely an above average thinker. His intelligence seeps through during his banter. It's another element of this show that I really enjoy
Chuck referencing Riley Freeman from The Boondocks trying to hustle Santa immediately made me a fan
Amazing episode! Thank you so much!!
The " BIG THANG (THING) " IS AN EXCELLENT TOOL FOR BEFORE THE BIG BANG. GLAD TO SEE THE INCEPTION OF THE TERM ON YOUR SHOW. CONGRATULATIONS ♥️!!!!!
Neil and Chuck are my favorite YTers to learn from. ❤
In one high school advanced physics class, the first semester was basically Newton's physics. Then second semester, we were told that Newton was wrong and subsequently was taught about vectors and then moving up to the basics of Quantum Mechanics or some of Einstein's Theory of Relativity. Even in college in my Physical Chemistry class, (a requirement for Chemistry majors, I have a BA in Chemistry) was told the same thing about Newton being wrong. In my head, since high school physics, I thought something was wrong about these statements about Newton's Laws. Newton's laws cannot be totally thrown out the window. He was right on a lot of points. The first and second law apply to the quantum as well. I thought to myself. And Newton's Laws work...to a point. I didn't understand why people would want to throw Newtonian physics totally away.
This Startalk video is the very first video that helped put my thoughts together. Einstein's Theory becomes Newtonian Physics for low speeds and low gravity. I was amazed how that clicked with my unease about throwing out Newton and his Laws. 😅 Newton was seeing only part of the picture of the universe, Einstein did not debunk Newton, he included Newton's proven laws in his wider view of the universe. That makes me think of singularities and dark matter and dark energy. First singularities: Einstein's Laws completely break down at the singularity point. Some scientists say tbey do not exist. Do they not exist just because we seem to have run into a roadblock? Or is there evidence in the equations and/or the outside world that suggests that singularities do not exist?
Same with dark matter ( and energy) are they thrown into equations like the "planet" Vulcan was? Or is there rational mathematical and/or real evidence that it (they) fundamentally exist?
these videos have been some of the most of the most enlightening thank you very much Please keep them coming
Ever since he mentioned what happens when the magnetic poles flipped and then why we need a magnetic field my brain was constantly going "so what happens to solar winds that travel toward the planet when the magnetic field is zeroed out?".
He glossed over it in the end but I think it would be interesting to have a detailed descussion on that.
Watching StarTalk is my bed time storyteller
I’m curious about the magnetized portion of the core. Can the portion of the core that is hotter than the Curie temperature be magnetized? (Maybe the Curie temperature is higher with pressure?) If not, then the magnetized volume would be near the interface bet the core and the crust (or mantel). Also, temperature would be part of the complex dynamics of magnetic pole movement.
This one episode got me to subscribe to this so great.
I love this show. Big props to Lord Nice for the Boondocks quote!
Chuck is awesome
I love Chuck Nice. He makes the show palatable to 6th graders. I'm 54 years old but a 6th Grader at this level of physics.
William Herschel, an astronomer best known for discovering Uranus, made significant contributions to astronomy, including the discovery of infrared radiation. His work required foresight in terms of developing innovative observational techniques and equipment, such as his large reflecting telescopes, which enabled him to explore the cosmos in unprecedented detail.Comparing foresight between William Herschel and Neil deGrasse Tyson is a bit challenging as they operated in different eras and contexts. Herschel's foresight was crucial in advancing observational astronomy during his time, while Tyson's foresight lies more in his advocacy for science education and public engagement with scientific ideas instead of actually making any groundbreaking discoveries.
NDT has the most infectious laugh!!! Love ❤ this video!
I was always curious about those sheets on the bottom of the JWST. I thought they were solar sails but that didn't seem to make much sense as far as efficiency goes with them blocking each other. Thanks for clearing that up for me!
You guys always make me smile. Thank you.
I knew the JWST had sun shields, but i didn't realize that it also actively cooled it. I said "That's wild! just a few seconds before you guys did, too 😂😂
@26'07'xChuck 's face was the same as mine!!!!😂😂😂😂
I go to PBS Space Time to get confused by an interesting subject and go to Star Talk to come away with actual understanding. I still love both!
Space Time is the cure for insomnia. His voice is mellifluous.
It quite mind-boggling to realise that all the objects we see don't have colour & that the colours we do see originate from the light reflected from them. This discovery helped me understand why night vision equipment always displayed images in variations of grey. I imagine eventually that someone will invent a display unit that does show the colour of objects at night by way of artificially colouring the images we see via night vision equipment, maybe it already exists but just isn't available for public consumption at the moment?
i think the cycle universe theory makes the most sense to me, the universe expands and collapses back into a big bang forever continuing a never-ending cycle. but who am I to say what makes sense...
It's a bit like trying to create a baby by crushing an adult- sorry for the unpleasant analogy, but the universe similarly grew with a series of development stages, you can't simply reverse. Hawking's cyclical model had us literally crawling back inside the womb- I think it's as absurd as it sounds, anything to get around a singular creation event.
@@SteveLomas-k6k it makes no sense if the universe only existed once roger Penrose suggested that the universe in the far future has the same properties as a big bang
This really helps me conceptualize science as a whole. I really appreciate this. Thanks!
I can't wait to introduce my newborn daughter to startalk, Dr. NdT, and Lord Nice
I love this show
9:30(ish) - i just realized the link between "F=ma" and "e=mc²"...Force and Energy are kinda similarly defined, equals mass, times how fast something is moving (capped at Speed of Light)
