    I have a question to the first part of the video:
    Our eyes' penholes, the black marble/circle lenses, are quite big. As a result, nearby rays are still able to reach the same spot on the retina, and therefore the picture should be blurry. Why is the picture we perceive still so sharp with that in mind?

    Could you not have a similar organ that only let's perpendicular photons through, but not have to touch it to the object? I don't see why these hypothetical aliens wouldn't be able to see at a distance.

    Nice, minerals are so fascinating and many have wonderful optical properties. As for the selenite breaking apart its quite common for selenite to do that, fibrous minerals tend to shed fibers and selenite is also one of the softest minerals, so soft in fact that you can scratch it with your fingernail. I believe its the combination of those two properties that make it fall apart so easily.
    I don't actually know if its safe but I don't think it's toxic as for breathing the dust its never a good thing to breath rock dust and fibrous dust is usually to worst but since selenite is so incredibly soft it's probably not as bad as other fibrous minerals.
    Btw if you really want to get your mind blown by selenite look for the crystal cave in Mexico, there are some very spectacular selenite crystals there.

    SO question: When you bring up a ruler really close to your eye, let's say a distance of x, it gets blurry. What if you placed a long selenite block of length X > x a distance of exactly x away from your eye. Would the #30 still be blurry then

    If we gad eyes that worked like that extra terestrial you were talking about we would probably strugle to see and our eys would have to be MUCH wider tan it is or els we woukd just see an area as big as ou erentena. Im not shure if i spelled some thing right because im only 12 but if we were to look at stars wit tyise eyes we woukd have to stand perfectly still, the plabet youre on an the planet or the star or planet you ar loking at but we would never be able toe see the entire thing or else or ereena would need to be as big as what you ar looking at but if you were able to to look at a far away planet without it moving out of sight i have no doubt that you are going to see it very clearer than we doe now but i personally dont want a retina the same diameter as a soccer ball just tooblooknat a soccer bal without me moving my field of vision or the ball moving constantly... Altoigh if we ad retinas that big with the material we would use our bodies would have to be much bigger or an entirely defferint shape based on some of youre other videos or an other habitat so i doubt that there would be much advantages to an eyesight like that compared to ours and i would love if you comented on thus if you have a selution to sone of the problems that the other eye would bring up becuase like i said, im o ly 12

    I looked up "orthographic camera" and found some stuff about a "telemetric lens" which can take pictures where things farther away don't look smaller... Now I really want to see a photo of a city with a telemetric lens.

    Aliens with selenite eyes, when looking at the earth, could see Michael's beard in all it's glory - provided they are patient enough to receive photons and have fancy eye stabilizers.

    do babies have to learn how to see the world right side up? Are they born seeing the world upside down?

    • timentimentimen
      timentimentimen Month ago

      That is an interesting question. However it is difficult to know. Newborn babies still see very badly/blurry. And the brain is very flexible. Adults adapt to 'upside-down' glasses within a few days. That is much quicker than babies develop their eye sight. So perhaps is does not matter how it starts as a baby - the brain will figure it out.
      On a more philosophical note: what does it mean to see right side up? Maybe I see everything 'flipped around', left=right, etc, but I am just very used to it. The brain only cares about creating appropriate responses/output to certain input.

    I would argue that things will aways look smaller just by locality. Michael's arguement is consistent with that by adding a non local detector, the ulexite/selenite sensor

    10:44 How does the light go in all directions after leaving the selenite (and converge towards your eye), if only parallel beams can enter it? Shouldn't the light leaving the selenite only go in one direction?

    but wouldn't i just see small fractions of my surroundings(the size of the retina) if i had these "mineral" eyes, because everything above and below wouldn't come at an 90° angle?

    • Antonio Falcone
      Antonio Falcone Month ago

      Yes theoretically, but probably it wouldn't happen because the photons on the external surface of the mineral will interact each other. And you will not able to see anything.

    Seeing is like touching but no limited by lenght of hands.. We can touch even far objects like sun or stairs and dont feel temoerature of them. We can recognize shapes and colors of things.. It have sense from evolution point, but what sense of seeing colors? Maybe without colors we cant see that far away? But we can only have black n white with greyscale.. So why colors,for what we have them?hmm
