Why The Sun is Bigger Than You Think

[@StarTalk]

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? 🌟

[@brianjones6500]

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

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?

[@joaoenes]

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.

Hey I had a question, I know light can change in color depending on distance, but does all light move at the same speed? Such as light from different types of stars.

[@josephmathew2154]

Yes all light moves at the same speed in empty space (a vacuum). However, light moves at a slower speed in a liquid(water) as well in glass (a solid), depending on the refractive index of the medium in which it travels. Refraction is easily demonstrated with a spoon half immersed in water which appears bent when we know it isn't.

[@Eric-wj8tn]

I think he's saying our bias for its diameter is 'visible light specifically yellow light'

[@southindianboi9050]

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!

[@RichardMcdonald-cg5yu]

He is talking about how we see it

[@theycallmeherbie]

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.

[@TheRajeshEffect]

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.

[@scarletevans4474]

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 🙂

[@brettpresta-valachovic3631]

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'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?

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".

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!.

You two are amazing together. Funny and Informative... Thank you

Chuck and Tyson is the greatest due 😮😮😮😮

Chuck cracks me up him talking with Neil is always entertaining
