The question keeps being moved. First is was "invisible" and "able to be touched", you are lying, you are moving as a pendulum QUOTE FROM INITIAL POST wait a minute, lets an object be only visible outside the visible spectrum, say UV eller IR, so we cant see it wait a while, we make it simple, suppose that this object lay on your table, you cant see it so it is invisible, do not confuse, it is not transparent, because if it were then you could see it, you don see anything on your table, your table seems empty now, if you drag your hand on your table will you sense it, will you touch and detect its shape? END QUOTE Not visible light, yes IR or UV, and can be touched, defines existance. So *you* cannot read. OK. *This* was the other shoe. You are simply looking for a fight. Goobye. plonk David A.

Bill Dear Mister Bill thank you for your feedback, i think you are right could you elaborate a bit? the other posters just said that the object still exists Not from my reading of what at least one of them said. No known object has zero effect on EM radiation in the visible spectrum. Even air, which you think may, refracts light differently depending on temperature. If you are trying to find issues with physics by means of thought experiments concerning things that do not actually exist; you will fail. Bill you know what, You are just a silly, stupid, troll. People tried to treat you a bit seriously - obviously a waste. Bill you been actually the closest understanding tha situation, than i wold had gave you 10 poings, but you are chiken****, following the currents and streamlines, therefore you only get 5 poings for now be happy, the others only gets between 0 and 2 poings wait a while, we make it simple, suppose that this object lay on your table, you cant see it so it is invisible, do not confuse, it is not transparent, because if it were then you could see it, you don see anything on your table, your table seems empty now, if you drag your hand on your table will you sense it, will you touch and detect its shape? would this invisible object be existing? you cannot say that light is wave and/or particle light is much more than that |

But as simply another incarnation of the dyslexic troll you are not worth my time or energy. I know Dirk reckons you are poking fun at troll/cranks but I believe it goes beyond that. You also want to annoy others and engage them in off topic nonsense. Lest I fall into your oh so obvious trap I will state now this is my last post in this thread - actually I think I will give your posts a rest for a while. They are rather predictable.

Smith moron, dark matter obj are transparent, huh? read fool http://www.physorg.com/news84797343.html "We know there is much more matter in the universe than what we see. For instance, the rotation velocity of observed spiral galaxies is much faster than the visible mass could explain," says Joachim Ripken, a researcher with the HESS Collaboration. "And we know that it is not the normal matter that we know." Ripken refers to dark matter, a type of matter that physicists know must be present in the universe, but that cannot be seen because it does not interact with light. It is matter, Ripken tells PhysOrg.com, that "we only know what it is not." |

Yes, of course it does. Invisibility has nothing to do with existence. this is an wonderful thing, would this object also be matterial or imatterial, only matterializin when appearing into tha visble spectrum? My definition of "material" does not include visibility as a necessity. There are many material things that are not visible. Air, for example. First of all, let's examine your hypothetical situation. Unless they are hot compared to the environment, visible objects *reflect* or *scatter* light that is incident on them, and so the light that comes from them is actually due to an external source. There are some objects that absorb some of the wavelength incident on them and reflect some -- for example, a banana reflects light in the yellow-green portion of the visible spectrum but absorbs light from the violet and red ends of the spectrum. Things that absorb all incident light in the visible spectrum appear black to us --- far from invisible. you contradict yourself here, you just said it exists Yes, it does exist. Nowhere in the above did I say that it doesn't exist. if not visible is tha object exiting or not this is wordsalad, has nothen ta do with the situation What you apparently want to imagine is something that is *transparent* to all light in the visible spectrum, which means that if the object were sitting on a table, then all light scattered from the table would proceed through the transparent object unimpeded, unabsorbed, unscattered to your eyes. This also is not unusual, as anyone who has walked into a closed sliding glass door can tell you. no, how many times do i have to say that i dont mean transparency whatso any fokn ever What you describe, though, is precisely that. Transparency. If something is invisible, it means that you can see the light scattered from objects behind it. That's what transparency means. Finally, if you want to probe the true nature of light by considering hypothetical objects, it's probably best to consider hypothetical objects that have some bearing to reality. what reality are you implaing that objects only detectable outside tha visble spectrum are not real enuff? No, I'm not. you cannot say that light is wave and/or particle That's right. Light has properties of both. wrong, i just that it is much more than that Yes, and that's all you said. If you have something more to say about the concrete nature of light, then say it. light is much more than that Yes, indeed. And much more than that is already understood about light, if you care to read further. I suggest a small book called QED by Richard Feynman. rather you should recomand one for your selv aparently only hobba sensed the problematics here, maybe this is becos he is doin qm so intensively And the book I recommended to you is one about quantum mechanics, which is why I recommended it to you. That way, you'll know a little better who knows what they're talking about other than your hunch. PD PD |
