Please, I must have some misunderstanding ,why I see farther objects smaller although there are reflected photons??!
nuby said:My guess is:
Because your eyes can only absorb so many photons. The closer you are to the object the more photons from the object will hit the rods in your eyes, making the object appear bigger.
For that, I use a telescope, a camera, and a printer.ahmedhassan72 said:Yes I read and understood,my question is can we make something that recognizes every thing at certain image size irrespectable to how far are objects..? thanks...
Doc Al said:Because they subtend a smaller angle.
While generally true (exception: lasers), this has nothing whatsoever to do with why objects further away appear smaller.wysard said:Smaller angles mean less photons. It's the reason that looking at the night sky and seeing a million suns far off doesn't instantly blind and incinerate you as seeing the same million suns as close say as ours...
Please don't just make things up.nuby said:(random guess) As the photons from the moon "fly" over the earth, the Earth's gravity pulls more photons to the Earth's surface, and to your eyes .. making the object appear bigger.

You seem to define "creativity" in physics as just making up any old nonsense without regard for evidence. That was most definitely a clearcut "crackpot" site, but I'm not surprised that you don't know the difference.nuby said:Sorry I posted that link about the suppression of creativity in physics. I honestly didn't think that was "Linking to obviously "crank" or "crackpot" sites is prohibited."
And you pretty much proved my point by deleting it, Thanks Doc Al.
This is due to a phenomenon called "distance compression" or "size constancy". Our brains automatically make adjustments for the distance an object is from us, so objects that are farther away appear smaller because they are perceived to be further away.
As distance increases, the size of an object appears to decrease. This is because the further an object is from us, the smaller its visual angle becomes. Visual angle is the angle formed by the object's edges and the point at which our eyes are focused.
Yes, objects that are closer to us can also appear smaller. This is because our brain adjusts for distance and perception, so if an object is closer to us but still appears small, our brain interprets it as being very small in actual size.
Distant objects can appear blurry because of atmospheric distortion. Light rays from the object are bent as they pass through different layers of the atmosphere, causing them to become less focused by the time they reach our eyes. This can result in a blurry or distorted image.
No, not all objects appear smaller when they are farther away. Objects that are very large, such as mountains or buildings, may still appear relatively large even when they are far away. This is because their size is so great that even at a far distance, their visual angle is still large enough for our brain to interpret them as being large objects.
