8:50 how can the bottom part of the sun not get shifted the same distance?

[@mikeboll9481]

1. Do the rays of light from the sun travel through space as an actual image of the sun... or as non-distinct dispersed light rays? It is the latter of course, but if it was the former... 2. Since light travels in straight lines, why would the mirage image of the sun that traveled 93 million miles to our atmosphere appear to us as the same size we always see the sun, instead of as if we were seeing the sun from 62 miles away (the height of the atmosphere)?

[@aarikagoel5917]

6:58 sir why is the shift stronger when the object is lower in the sky; the refractive index has to remain constant so if the angle of incidence will increase so will the angle of refraction ?

[@furiousarpan7473]

If you have studied total internal reflection you might recall that the ray of light was refracting more and more as we increased our angle of incidence and at a particular angle it got refracted as much as it reflected in the same medium, you can relate the same thing over here, the more angle of incidence means the more bending of light so the shift will be more stronger

[@sauravhere...]

​@@furiousarpan7473then why objects near horizon have max shift

[@icse03tejasc62]

Thanks for it

[@darshinimd8973]

you forgot to enter the earth's rotation data, what is the rotation speed? how can the sun run 24 hours a day? while the earth rotates, who knows how many kilometers per hour? oh my head is spinning too

[@crowxe]

15 degrees per hour

[@madhavgarg9031]

Thank you very much 🙏

[@stephenjacobsen4616]

why did you curve the horizon? that doesnt mimic reality... peace

[@arielatomhc]

The way your earth is spinning means the North and South pole have tilted 90 degrees.

[@aanchalchauhan3052]

Yes I know

[@iamhearelshaddai]

kzbin.info/www/bejne/oJqngKuAhcqcqtk

[@ShadowTheHedgehogCZ]

Is this really why sailors in the earlier times used to look at the locations of the stars far from the horizon for navigation? Because yeah, I understand that this is how it works. But how could they have understood it? If they did, then they knew that the Earth was round. I thought that the knowledge of Earth being round was not so popular in medieval times.

So the sun is 2 minutes behind itself. Ok, then when the mirage of the sun that I have followed for 2 minutes is still there how come I don’t see the real sun rising?

Its also compressing into the vanishing point thus debunking a globe as zoom cameras show.

[@fredcaldwell9824]

This video is wrong for the simple reason Helio Cosmology demands that the sun's light takes 8.3 minutes to get to us on earth and that calculation is completely omitted here. It also ignores that the sun moves its own diameter (or height) every 4 minutes. As such, at sunrise the actual position of the sun would be more like twice the height of the sun ABOVE the horizon.

[@AdonayFloresLaMota]

Why would you need the calculation of sunlight to earth? The sunlight is already hitting earth... that calculation would be for no reason...

[@awesometamilzhathemass898]

Thanks a lot

[@arnowtc4674]

Does the fact light from the Sun takes 8 minutes to reach us tell us something about where the Sun actually is when it rises and sets too?

[@luigimichini4597]

No, it does not affect the sunset or the rising of the sun, it does not matter how far a star is, because the sunset takes place on earth between the observer and the horizon.
