With all the super technology at our fingertips,I don't understand how a 6'9" man can walk around in the light of day and can't be detected some way.I'm a reasonably intelligent person.Can someone shed some light?

because we're not trying hard enough.  We haven't put CIA and FBI agents in the right spots and our military has no idea what's going on.  Then we had to go and attack Iraq and get a new set of problems to focus on.  Pretty damn messed up that one guy can orchestrate the murder of 3000 Americans and 5 years later we still have no idea where he is.

to think that we are the only living beings in this large universe is silly. Why have they not made themselves seen to us, is a different story.\nIt could be that they are at the same level of technology as us, they could be behind us or they might be highly advance and will not make themselves know to us until we are at their level. \nIn short without continuing to go on a rant\nYes, they are out there.

At 40, I guess I'm OLDER. LOL When did that happen? ;-b I'm pretty clued up with techno stuff as I live in a wheelchair adapted bungalow and have lots of gadgets to help me in my daily life.  I do wish someone would invent something better to help me put my shoes on though! LOL  The basic shoe horn is no good, even the long handle one, as my ankle doesn't flex enough to even put my foot in the stupid shoe!  Anyone who could invent a "shoe-putter-on" would make a bloody fortune!!

I was willing to give this a reasonable chance until I read this:\n\nOne early morning in '99 Range was returing from Henderson when a low-flying craft dropped a trail right overhead along Boulder Highway. "It covered my car with a sticky web-like coating and I saved a specimen in a jar. Microscopic fiber-like filaments," Range reports\n\nWhat was the outcome of the analysis of this specimen?  If this happened in 1999 don't you think she would've taken it in for analysis by now?  \n\nAnd what does being over 25 have to do with anything?  Are all people over 25 blind or something?\n\nI live in NJ so I can't say that its completely untrue but, I find it hard to believe that so few people have come forward.  A lot of people live in Vegas, I would've expected more people to have said somethin by now and I would expect this to be national news if it were true.  People aren't as complacent as you think they are, when it has to do with their long term health and the health of their children, people are usually very vigilant.

You guys are idiots.\n\nAnyone that said internet or anything of the like, obviously works in a cubicle and is alergic to sunshine.  Go outside, get a tan, and play in the woods, you geeks.\n\nFirst to survive in almost any climate you only need a few things. A sharp pocket knife, waterproof matches(not a total nessesity), candle ( for a ready fire source without using all your matches), Compass(duh),Monofilament fishing line (at least 50 yds), and solar-still items such as a plastic sheet (5ft x 5ft), plastic or surgical tubing (5ft) and a plastic cup (collapsible).

How does one accidentally put sunglasses in their pocket? Anybody? Anybody? I don't think so. 1 vote klepto.\n\nPeace

Well, if you're traveling faster than light, then the light can never be in front of you.  There would be just a big nothing, probably drive you crazy if you looked at it.  I know, I come from andromeda.  We travel through space backwards so we can see where we're going.

For one, cameras today can't produce the resolution that a human eye can produce.\n\nThey are working on artificial eyes and radar, and I think a Retinal Transplant might help you. Talk to your doctor about if you are a possible candidate.

Why even diginify them with an answer?  Being a short person as well I understand your plight but you know what does being short/tall really matter in the grand scheme of things?  Embrace your height my friend and anyway it is being vertically challenged not short.

Are we alone? Probably not. It would be fairly conceited to think otherwise. What is the 'grand secret' the government doesn't want us to know? I really doubt there is any secret. I don't believe any foreign intelligent life has ever visited the earth. Frankly, if they have the technology to cover the vast distances to visit us, then they would have no interest in doing so. If it was the land they were interested in, then we would not be hear anymore. They probably could anihalate us in the blink of an eye.

Last time I saw OBL on one of his home-made videos, I didn't notice a GPS watch on his wrist, did you?  I doubt his mommy and daddy keep track of him anymore.\n\nAlso, Pakistan and Afghanistan are not the most technologically advanced nations in the world, so using technology to track him down is substantially less effective than simply putting agents in the field.  Most people today are still tracked down using good 'ol investigative techniques (questioning suspects, tracking bank activity, stakeouts, etc.) than tracking phone calls.

A device u lookin 4 is 4 short term\nmaybe sit n pee can work too\n\nBut ultimately u gotta be lookin at weight reduction\nWalking is a good starting point\nIncrease time / length of walk gradually\n\nDiet very important .. see a dietician .. worth the effort\nthey study each case, body's metabolism / catabolism\n\nSure other healthy habits can help in this ... and more than anything else ... he can lead a HEALTHIER and LONGER life\n\n--- best of luck, but just do something ... get started !

GPS is not accurate enough? If I'm not wrong, GPS have the potential to measure to accuracy up to few cm. And you only need feet accuracy, it won't be problem with GPS. (Well, you had to dig your pocket deeper for a prime quality GPS though)\n\nPerhaps you can use a radio frequency device, but make sure you buy one that uses frequency that is high enough or you'll get the wrong reading. I don't know if there is any sold in the market that is specifically made for calculating distance though. And I'm doubting that a radio frequency reading is accurate too if your line of sight is not clear.\n\nPerhaps you should use a ladder or climb the bushes there and uses laser.\n\nOh yeah, I forgot, if you know the coordinate of the two points you're measuring (use GPS for this), perhaps you can use Google Earth (http://earth.google.com/ ) to plot the points there and use the distance measuring device provided there. Google Earth can measure up to cm accuracy (provided the correct coordinate)

no.  I'm very concerned about this type of technology because it IS here just waiting to be implemented , but i think it is dangerous.  before long all people would have tracking devices implanted so that your whereabouts could always be known. that's scary.  it would of course start with a good sounding reason...like as a solution to identity theft but the result would be disastrous.  at the risk of being called a conspiracy nut, i do think that this may very well be the "mark of the beast" from revelation without which no one will be able to buy of sell.  no thanks..not for me or mine..i would fight any such attempt to institute this practice.

good grief - there is a lot of 'part' knowledge here...\n\nyou need to break this down and talk about the different parts of what the original question was asking.\n\nif it was 'see', the explanation would be the same as for hearing by the way. (it would be easier to explain about seeing)\n\nhere goes...\n\ninside your ear you have these little hairs (cillia) that are a certain distance apart. when a sound wave enters the ear the wavelength of this wave will stimulate hairs at both its high energy points (its troughs or peaks, you choose, not important) your brain knows the distance of the hairs and so can interprut this wave distance between two lots of hairs being stimulated. thats how you get the frequency (number of wavelengths in a second) of sound in your ear. the volume (loudness) depends on how vigourously the hairs are moved by the sound wave. (thats why you can go deaf listening to loud music - you kill those little hairs if too loud). \n\nnotice i said sound!\n\nyour question is about electromagnetic waves. radio waves and visible light (green) waves are both of the same stuff (light energy - some we can see and some we cannot). the organ for detecting this energy is the eye. inside the eye, the retina (back of the eye) has special cells called rods and cones for detecting different wavelengths (i believe this is what your engineer was on about). each of these cells has a specific chemical for detecting a certain wavelength. lets pick on one.\n\nthe red light cone has a protein inside that has a special part that can move to a slightly higher energy form (a more awkward position for the proten so it wants to get back to where it was before - think of bending a ruler... the more you bend it, the more it wants to get back to where it was... so the higher the energy it has) when red light is shone on that protein (inside the eye) it provides enough energy to move this extra part of the protein (called an apoprotein portion is anyone wants to know) to a higher energy state and this is enough to induce (make happen) a signal being sent to the brain that says 'red light detected' and we see red light.\n\na similar thing happens to green light.\n\nin physics, when we talk of waves whether in music or lihgth or nanometers, if you have something of the same wavelength then it is detected as the same.\n\nif you have something of a different wavelngth then it is detect as different ( or in the case of the eye.. or even the ear, not detected at all, unless your are green, red or blue light)\n\nbut if you have a wavelength that is say  x2 bigger, of x3 or x6 or x2000 times bigger exactly, with no extra and no bits needed.. it has to be exact. then these also will be detected.. A BIT. we call thesse harmonics. this is a word that belongs to music.\n\never notice the way a piano has all those notes (only 8 notes and yet so many keys..?) these eight notes are repeated but in higher registers/keys, but they are still the same note.... a higher harmonic. all these wavelenths are doubled or trippled or what ever.\n\nso, because there will be a harmonic of green light in the radiowave part of the spectrum... it can theoretically be detected. so you could theoretically detect green light (with the eye) and radiowaves (theoretically with the eye)... but never with the ear :-)\n\nhappy days - now lets look at information theory! why do we always lose information and yet still maintain the integroty of the message? at what point is the message lost?

Does night actually move faster than day?\n\nThat doesn't really make sense, because while it may be night in one place, it will be day on the other side of the world. So they must both be moving at the same pace to be happening simultaneously, right?\nSorry I can't be more help, but I believe they both move at the same pace.

The size of an object you can resolve with an optical system has a theoretical limit given by the wavelenght of the light you're using divided by the diameter of the optics multiplied by 1.22. If you plug the numbers in you find for a 1 foot diameter optical system at visible light (~400 nm) at an altitude of 100km, the smallest thing you could see is on the order of a foot, give or take (rough calculation). You could definitely not read a postage stamp or a wrist watch. Maybe a license plate with some bigger optics, but this is ignoring all sorts of atmospheric scintillation which screws things up.
