    Which backs up my thesis.

    Tall people are further away from their food, so they have to see it better or they may spear their hand with a fork thinking it's a slab of ham or something.

    But body geometry is determined by gravity. Moles are short and sorta flat because they tunnel just inches under the ground and leave bumps all over my lawn. So when I roll my lawn with a heavy lawn roller, or run around and stomp on mole tunnels, the moles in the tunnels get compacted along with the dirt. Making them short and sorta flat.
    Ergo, they never have the opportunity to grow tall and develop the need for good eyesight.
    All tall moles with good eyesight are stomped back into the ground and compacted much more than their shorter counterparts, this causes severe internal injury and kills them off.
    It also flattens their eyeballs, just like the astronauts, thereby ruining whatever good sight they may have developed.

    if the force of gravity suddenly dissappeared, you would see the same view .. until of course you flew off into space and all the oceans evaporated.

    We have a whole different set of phororecptors and messaging cells to our occipital lobe/visual brain areas than a mole or bird. We would still not see with equal distance and acquity.

    I wish I had a dime for all the times I have mistaken my hand for a slab of ham. :D

    This is why Morocco Mole, and all other cartoon moles, wears glasses.

    yea, theres no way to even prove for certain that what i see as the color red, corresponds to the same hue that you see when looking at a "red" object. We would both call it by the same color name (red) cuz thats the english word to describe objects of that color .. doesn't mean it produces the same subjective experience of color in everyone who views it.

    some animals have less photoreceptors than us, some have even more (4 receptors in their eyes for color) because their survival depends on them seeing colors that we don't even realize exists

    Gravity bends light waves. - Al Einstein

    Here is my cat.
    Notice how gravity bends the light rays as they are reflected off the mouse and bent back towards the ground and the Earth
    (Center of gravity.)

    .........................................................................................[​IMG]
    [​IMG][​IMG][​IMG]

    Therefore the cat can see the mouse.

    If there was no gravity the light waves would continue off into space and the cat would not be able to see them,
    as he is too close to the ground unless he gets within 125 feet of the mouse due to the angle of light deflection.

    ..................................................................................[​IMG]

    That's why cats like to climb trees. They can see the mice better under low gravity conditions.

    have you ever climbed a tree before?

    it's not exactly a "low gravity" environment.

    if you fall, it's at an acceleration of 9.81 meters per second squared. doesn't matter if the tree is 20 feet tall or 250 feet tall. because those distances are dwarfed by the approximately 21,000,000 feet to the center of the earth. even distance from sea level varies more than the height of trees.

    if your theory was true, then cats at sea level would have better vision than cats at high elevations (like mountain lions)

    i honestly can't tell if you're being serious about this theory of yours.

    Yes something to take note of and I agree with that to an extent. Another example is that I think generally speaking women are more adept at deciphering shades of colors, it seems they often have a more visceral reaction to it. Having worked with drapery and flowers, I found myself somewhat baffled at the reaction women would have to certain products.

    However barring forms of blindness, I think we experience color similarly enough to mostly agree on it. The examples I would suggest are stop signs and street lights, I don't think our road systems would function as efficiently if our variability in experience of color was too discrepant and solely dependent on shapes. Also marketing for restaurants, businessess, and shops sometimes use particular color schemes to appeal to people to evoke certain moods to sell their products. I think it's pretty apparent that fashion takes advantage of our agreement on the experience of colors as well. Not to mention, if we didn't have an agreement on a color such as "red" as humans we would likely not have consensus on cosmological stuff like the age of many celestial objects, such as the stars and universe.

    i think what ace is saying is that since you would have ALWAYS seen red as another color, but you learned to call that hue "red"...that you'd name the color correctly.

    theoretically, everyone could see a different shade of red when they look at a stop sign or red light, but it wouldn't matter. because they learned from the start that THAT color means "red" and it means stop.

    i don't think it's true because of the way that our eyes are structured, but it's a thought that i've had and tried in vain to explain to a few people.

    if one astronomer looks at the red shit, but actually sees green....as long as it's a constant, it's always the same thing he sees...he would call it red because that's what it was taught to him as. am i making sense? at least to ace?

    It's not that women are more adept at deciphering shades of color, its they have a lower prevalence of color blindness than men - good observation though :2thumbsup:

    The first major study of color blindness in a multi-ethnic group has uncovered that Caucasian males have the highest prevalence among four major ethnicities, with 1 in 20 testing color blind. Researchers also found that color blindness, or color vision deficiency, in boys is lowest in African-Americans, and confirmed that girls have a much lower prevalence of color blindness than boys. The study was published in Ophthalmology, the journal of the American Academy of Ophthalmology

    There have also been studies that show women are more adept at deciphering shades of color... :sultan:

    loud and clear here, that's exactly what i was tryin to say.:sunny:

    even color blind people can still drive .. they learn the positions of the signals so it doesn't matter if the lights look the same color they learn that the green light is on the bottom and the red light is on the top.

    Anyone thats ever been to a general admission concert knows that the taller people can see better.

    its just geometry (or trigonometry really) that causes this .. angles and shit, think about it, as you move higher the horizon is gonna appear to get closer because the angle is decreasing.

    if you get high enough what once was a 180* angle now appears to right beneath you...ive never flown in an airplane before but what ive heard from people that have is that you can see a whole lot from up there :)

    How does the color blind person react to this stop light I wonder?

    [​IMG]

    From the brief amount I looked into it, the color blind still see a difference in the light turning, maybe it's the brightness of the light as much as the color for them? Still on some of those glaring sun days on the street lights seems like it would be extremely difficult for a color blind person to decipher.
