When I observe a visible light source, like the sun or a light bulb, why do I observe the light source as a confined object? Like why is the sun or a bulb or whatever seen as a confined ball of glowing light? Shouldn’t I Just see beams of light everywhere? Like a car passes you at night and you can see it’s head lamps as confined bright glowing things. You can see what those lamps illuminate but you don’t see anything in between. Why? I understand that the photons have to hit an object and be re-emitted and then hit your eye for you to see an object. But when I look at a visible light source I see that source as a confined glowing object. Why is it confined? Like why are glowing things able to be seen as a confined glowing thing? Like let’s change the source to fire - why do I see the flame as a confined luminous thing? If the plasma of the fire is emitting visible light why do I see it as a confined thing?! Also I am worried I can’t actually explain what I am wanting to know. So help clarifying is welcomed.
Okay I forgot my login information but I need more assistance from this wonderful community, please if I may? I appreciate all the answers and they all make sense but I think what I was attempting to ask was -
Do photons somehow carry information. Just because a photon enters my pinhole retina doesn’t explain WHY my brain knows to construct an image from it in such a way as to make a thing appear a certain side or shape. Also if photons are the reason I see other things via refraction or what have you, it doesn’t explain why I can see their source if they’re not refracting off of anything. Or are they? Perhaps the atmosphere of the sun is the point of refraction? Or the glass of a light bulb or the plasma gas if a fire? How can a photon show me it’s sources as a glowing thing, also show me the tree and remain invisible as it propagates. Is this because my brain only presents me an edited version of reality? How does it do that? Photons then must be some type of information packet. Is there a measurement of how much information a photon can store? Is any of this making sense to anyone? This is why I was saying it’s kind of a abstract question - I hope I’ve made the question more clear. Any book recommendations I can read that may answer these types of questions are gladly accepted, even if it may be out of my depth I would still appreciate anything from anyone. Thank you.
