How can understanding our spectral and spatial biases in measuring the Sun’s diameter enhance the accuracy of spectroscopy for determining the sizes of exoplanets and other stars? 🌟
I think it would be important to understand other stars output and "gravity well" in order to determine if the rock orbiting an interesting star could be gravitationally relevant to our current human physical needs. Or you could have Ronke Olabisi engineer "some of us" to not give a damn and live on the rock and for reasons I don't understand yet...report back on their findings. [I'd just send a robot probe; but what's the fun in that?] I elect trump to be Ronke Olabisi's first victim ha ha. The truth is all reports wouldn't be science but "look where I am!" - End of report
If we don't have an agreed upon objective or subjective definiton, then it's a pointless question. I doubt people would agree to include the range of the sun's gravitational pull in the measurement of it's diameter
Hey a random human here, earth 2024.. I appreciate you both and whoever else might read this comment. Great conversation and I'm glad i could experience it.
I will be passing away in the next few days. I just wanted to say thank you for all the laughs and incredible education about the stars and all that surround them. Thank you so very much.
I have a brother-in-law in the same situation. I can't think of anything comforting to say, except, if N.D.T. and others are correct about mater, specifically atoms, which we are all made of, then what an actor once said when asked what he thought happens to us when we pass away, his answer was ' we go home ' and that makes perfect sense to me.

The Sun’s immense size is already mind-blowing, but when you think about the countless other stars out there that dwarf it, it’s absolutely insane. It’s no wonder that trying to comprehend objects of this scale feels almost beyond human capacity.
I heard someone say if you scaled the Earth down to the size of a tennis ball. The largest known star (KNOWN star) would be the size of Philidelphia. 😮.
Me too . I’m happy it’s science though . With one sentence Neil became my science teacher for life . He said you don’t have to be an astrophysicist to learn about the universe or a scientist to learn about science. I had a science teacher tell me in 5th grade that my math skills were not good enough to consider perusing a career in science . I’ve always loved it though. I’m a lot more like Chuck . I’m continually amazed and mind blown by the mass amounts of science we do not learn in school. They are a fantastic team and I always feel great after spending an hour watching Star Talk !
Love you guys. You educate us with out confusing us. You also make us laugh. Dont stop what you two are doing okay. We've learned so much and always enjoy your humor.
I wouldn't even know what to talk about if I had a chance to meet up with you guys. I love this channel beucause you explain a lot of different topics in an easy and relaxed way
I love Chuck, he's so clever and witty while remaining humble. I want to see a movie where Chuck is teleported to another timeline and he has to explain Einsteins theories and all of advanced physics to a new civilization. The ultimate test of what he's learned. A better version of idiotocracy

100x100x100 is indeed 1M but that would be filling a cube not a sphere, since the 100 is "only" at the central axes. and would decrease as one goes to the edges. *pushesnerdglasses*
Yes @@loccc88, the volume of a sphere is 4/3πr^3 or πd^3/6, which is roughly speaking d^3/2. But again he was just talking wrt to powers for understanding
If you really think about it, the volume of the sun ends where nothing would be impacted anymore by it's gravitational field or it's infrared (heat) rays. So weeelllll behind our solar system. So in a way, we all live in our sun.
I tried to anticipate what this video was going to be about and got excited about the prospect of the value of Pi being different due to gravitational warping of space and time at the "surface" of the sun. I have no idea if this would even be measurable for the sun but it would have been a cool thing to talk about 🙂
❤ from Sri Lanka 🇱🇰 Being the fans enthused by 'Cosmos' tv series, respect to this wonderful type of explanation with the great sense of humour ! A big thumb up to chuck's amazing support too ! 😄🤙
I love how Niel flexes his right hand and then grabs with his left. It actually is a really potent conclusion to his message about deceitful presentations.
Isn't the sun considered a sphere and not a cube? 100^3 isn't the right calculation. If that radius is 50 earths, then wouldn't the volume be 524,000 earths?
No the, diameter of the sun is 100x the diameter of the earth, then the radius of the sun is also 100x the radius of the earth. Since both are spheres, the volume of the sun is 100^3 times the volume of the earth. If you can pack 100^3 earths into one sun is another question, since spheres don't pack the entire space it is less than that.
@@hiranga Approximating the Cubing of 4 thirds pi r squared is not that easy for a RUclips audience. Its an approximation afterall so assuming cubes is an easy enough approximation. Besides when living in the approximation domain, tolerance is part of the domain.
This video is another pure gold....in 10 minutes not only did we know about the sun & the earth we also learned far more deeper stuff...the stuff that Neil mentioned about the many faces of truth is actually really really deep although they made light of it in the episode..nature has knack of 'hiding' (as a figure of speech) deep & profound truths in plain sight in seemingly unrelated and/or trivial matters...i think it has something to do with patterns manifesting repeatedly in ever so different ways (many times subtly) in many (completely different) things...one just needs to be curious and attentive to nature & it will teach...if we listen..this is often told like a cliche...but all serious thinker often vouch for it...quite simply because its true.
Ive said it all along, the sheer scale of everything in the universe as compared to us, is mind blowing. We are literal specks in this enormous universe. What we hold dear means absolutely nothing in the grand scheme of things.
Yes you're right, the sun is white. White light is made up of roygbiv (red orange yellow green blue indigo and violet light). All those light colors combine to make the visible light spectrum, white. What NDT says there is, not only are our eyes biased to just the visible light spectrum and not other spectrums like X-rays or gamma rays or something like the Magentosphere, it's also specifically biased to the just the yellow light part of the visible white light coming from the sun. He says this to remind us of how narrow and limiting our vision is and we should not be using that to determine the edge of the sun as it actually spans welllll beyond what the eye sees!
The sun is white till it reaches earths atmosphere, the gases, carbon dioxide and oxygen make the light to humans on earth appear yellow. If you were in space, above earths atmosphere you would see white. Our atmosphere filters out all the other colors. This is why cars use yellow lights for fog lights, yellow light can "punch" through the fog. Also the same reason the sky is blue and not black.
The Indian astronomer and mathematician Aryabhata I (476-500 CE) estimated the Earth's circumference to be 24,835 miles (39,968.058 km) in his book Aryabhatiya. He arrived at this estimate by studying the positions of the sun and moon at different times in the same latitude. Aryabhata's calculation was used for many years without change.
Your point is because you see the sun thats why its real? Poor quote and poorer logic 🤣 God is everywhere, same are particles, we don’t see but they do exist
You think you're something, standing there with your worries and woes? The sun, that cosmic furnace, has been burning for billions of years, dwarfing our petty concerns. ❤
I love how you make something as apparently simple as the size of the Sun an interesting topic of discussion. It was very informative. I'm not sure where to submit a question so I'll put it here in the hope you'll see it. I've seen a lot of articles about the Alcubierre warp drive, how they would work, and etc... what I'd like to know is what would happen if someone accidently came in contact with the warp bubble? Since the warp bubble is distorting space and time, and the individual is in that particular space and time, would nothing occur or would they be spaghettified by the distortion?
This strategy has been a game-changer for me. I followed your advice and got 8 out of 9 - the best result I've had in ages. Thank you for sharing your knowledge and experience with me
This entire theory also applies to other aspects of the Universe. "Don't declare this to be the diameter of the sun if it's only based on what your eyes see". We shouldn't declare something to be fact until all other aspects have been exhausted to determine the limits of whatever we're talking about. I'm speaking of closing the door on elements of a spiritual life (not religious life) if we haven't experienced all facets of what is!
I love how mathematicians use the maximum distance possible between two points of a given set as the definition of the *diameter*. Be it a square, a triangle, a random group of disjoint points, you can easily give its (finite) diameter this way! Thus, even is radius is smaller towards the pole, we use the bigger one for diameter 🙂
i calculated the acceleration and velocity of Neil's reflex. the reflex has occurred exactly at 7m.30s.13 frames per second and his hand moved approximately ~40cm at the final point at 7m.30s.16 frames per second, judging by Chuck's arm length to the right which is equal to 0.4 meters the hand had moved over 3 frames in a video with 30 frames per second, therefore, t = (3 frames) / (30 frames/seconds) = 0.1 seconds and to find the velocity v = 0.40 meters / 0.1 seconds = 4m/s and the acceleration from his initial velocity to 40 cm is: a = (4m/s) / (0.1s) which is equal to 40 meters per seconds squared to put this in perspective, Niel's hand accelerated 10 times faster than an olympic athlete in a 100-meter dash, a cheetah can accelerate up to 15m/s^2 so Niel's hand was 2.6666667 times faster, moreover, if we were to make the analogy for the acceleration of gravity on earth at 9.8m/s^2 with earth's current diameter of 12,742 km, Niel's acceleration can simulate the gravitational acceleration of a super earth with the same density as earth by the formula for gravitational acceleration g = (4*pi*G*rho*R) / (3) and since the density is constant we just use a linear ratio (g_2/g_1) = (R_2/R_1) where g_2 is the acceleration we want (40m/s^2), g_1 is earth's acceleration (9.8m/s^2), R_2 is the radius we are looking for and R_1 is earth's radius (6.371 km). we rearrange the equation for R_2 = R_1 * (g_2/g_1) = 6371 * (40 / 9.8) = 25,988 km in radius and we multiply by 2 to get the diameter 51,976 km thus, for Niel's reflex acceleration of 40m/s^2 to imitate the mass of a super earth, the diameter of the planet would have to be 4.08 times our planet's diameter or 51,976 kilometers!
I seen this comment right after my initial he has some of the quickest movements I've ever seen on video, athlete level speed and you sir confirmed it. Thank you, this is legend!.
I found out my junior year on highschool that correcting the questions on the SAT was NOT allowed. They absolutely did not want to hear about the diameter of the earth or or much less our sun

5:35 Neil says ‘specifically yellow light’, but I thought he always argued the sun is white?? Can someone explain
I think he's saying our bias for its diameter is 'visible light specifically yellow light'
Yes you're right, the sun is white. White light is made up of roygbiv (red orange yellow green blue indigo and violet light). All those light colors combine to make the visible light spectrum, white.
What NDT says there is, not only are our eyes biased to just the visible light spectrum and not other spectrums like X-rays or gamma rays or something like the Magentosphere, it's also specifically biased to the just the yellow light part of the visible white light coming from the sun.
He says this to remind us of how narrow and limiting our vision is and we should not be using that to determine the edge of the sun as it actually spans welllll beyond what the eye sees!
He is talking about how we see it
The sun is white till it reaches earths atmosphere, the gases, carbon dioxide and oxygen make the light to humans on earth appear yellow. If you were in space, above earths atmosphere you would see white. Our atmosphere filters out all the other colors. This is why cars use yellow lights for fog lights, yellow light can "punch" through the fog. Also the same reason the sky is blue and not black.

just finished watching this one. one of the most profound episodes to me.
You think you're something, standing there with your worries and woes? The sun, that cosmic furnace, has been burning for billions of years, dwarfing our petty concerns. ❤

Chuck is hilarious man these two together is pure comedic educational gold....Nay! Diamonds!!!
I love how you make something as apparently simple as the size of the Sun an interesting topic of discussion. It was very informative.
I'm not sure where to submit a question so I'll put it here in the hope you'll see it.
I've seen a lot of articles about the Alcubierre warp drive, how they would work, and etc... what I'd like to know is what would happen if someone accidently came in contact with the warp bubble? Since the warp bubble is distorting space and time, and the individual is in that particular space and time, would nothing occur or would they be spaghettified by the distortion?
This strategy has been a game-changer for me. I followed your advice and got 8 out of 9 - the best result I've had in ages. Thank you for sharing your knowledge and experience with me
"That'd be my Uncle Daryl" is the funniest line of the year for this. That was hilarious
This new editing style is awesome!
It's always a treat to sit and listen to you two!
Happy to see Chuck in all your videos!
This entire theory also applies to other aspects of the Universe. "Don't declare this to be the diameter of the sun if it's only based on what your eyes see". We shouldn't declare something to be fact until all other aspects have been exhausted to determine the limits of whatever we're talking about. I'm speaking of closing the door on elements of a spiritual life (not religious life) if we haven't experienced all facets of what is!
Deep...
Theories are backed up by empirical evidence that can be researched. There's no empirical evidence of a spiritual life.
0:52 the audio is correct, but the animation is misleading: it’s not the diameter of the earth that’s ~40,000km, it’s the circumference.
This was one of my favorite podcasts!
I`ve been reading Neil`s books since I was a kid in the 1980`s.
These two are pure joy together 😂
I love how mathematicians use the maximum distance possible between two points of a given set as the definition of the *diameter*. Be it a square, a triangle, a random group of disjoint points, you can easily give its (finite) diameter this way! Thus, even is radius is smaller towards the pole, we use the bigger one for diameter 🙂
A great team and an amazing teacher are laughing a lot while mastering the philosophy! I adore you both just too much.
i calculated the acceleration and velocity of Neil's reflex.
the reflex has occurred exactly at 7m.30s.13 frames per second and his hand moved approximately ~40cm at the final point at 7m.30s.16 frames per second, judging by Chuck's arm length to the right which is equal to 0.4 meters
the hand had moved over 3 frames in a video with 30 frames per second, therefore, t = (3 frames) / (30 frames/seconds) = 0.1 seconds
and to find the velocity v = 0.40 meters / 0.1 seconds = 4m/s and the acceleration from his initial velocity to 40 cm is: a = (4m/s) / (0.1s) which is equal to 40 meters per seconds squared
to put this in perspective, Niel's hand accelerated 10 times faster than an olympic athlete in a 100-meter dash, a cheetah can accelerate up to 15m/s^2 so Niel's hand was 2.6666667 times faster, moreover, if we were to make the analogy for the acceleration of gravity on earth at 9.8m/s^2 with earth's current diameter of 12,742 km, Niel's acceleration can simulate the gravitational acceleration of a super earth with the same density as earth by the formula for gravitational acceleration g = (4*pi*G*rho*R) / (3) and since the density is constant we just use a linear ratio (g_2/g_1) = (R_2/R_1) where g_2 is the acceleration we want (40m/s^2), g_1 is earth's acceleration (9.8m/s^2), R_2 is the radius we are looking for and R_1 is earth's radius (6.371 km). we rearrange the equation for R_2 = R_1 * (g_2/g_1) = 6371 * (40 / 9.8) = 25,988 km in radius and we multiply by 2 to get the diameter 51,976 km
thus, for Niel's reflex acceleration of 40m/s^2 to imitate the mass of a super earth, the diameter of the planet would have to be 4.08 times our planet's diameter or 51,976 kilometers!
I seen this comment right after my initial he has some of the quickest movements I've ever seen on video, athlete level speed and you sir confirmed it. Thank you, this is legend!.
Thanks guys. Learned alot🙏🏻
Thank you! This was a fascinating talk, as usual. 🙂
I found out my junior year on highschool that correcting the questions on the SAT was NOT allowed. They absolutely did not want to hear about the diameter of the earth or or much less our sun
