Why is it bad to look directly at the sun?

The Sun is very bright and by focussing the light onto the back of your eye (the retina) with or without a telescope, you are putting a lot of energy (both optical light and infra-red) onto a tiny area. At some point in your life you may have tried to set paper on fire using a magnifying glass, so just think about that being done to the back of your eye. It isn't nice. Even more scarily is the fact that the retina of your eye does not have pain receptors, so you will not even feel the damage being done. It may not even become apparent until later.

It all has to do with your distance from the sun.

Maybe get it checked out by an optician.  If your pupils are dilated in strong sunlight you could be getting damage to the inside oif the eye...;

He observed sun spots moving on the surface of the sun. All of them moved in the same direction, just as similar things on the surface of the Earth would do. \n\nIt may be of some interest to note that this was only an inference from the evidence. A very convincing inference and enough, wiht some other things, to cause trouble with the Church. Direct evidence of the sun's rotation came rather later, with photography and better telescopes, and somewhat later, Doppler spectroscopy. \n\nSince Galileo is thought to have lost his sight at least in part because of his solar observations (quite dangerous to look directly at the Sun, but it's still more dangerous to look at it directly through a telescope), these later observational techniques probably saved a goodly number of eyes.

The short answer is: Yes.\n\nI think the previous people who attempted to answer this question did not read it carefully. \n\nThe atmosphere is in layers, of different densities, that refract the sunlight and different colors different amounts. The light is bent downwards because the speed of light in the upper layers is greater than the speed of light in the layers closer to the ground. One can see this effect in the change in shape of the sun as it sets, and the effects like disconnected pieces of sun, green flashes,etc. This is just the same as the effect that creates mirages, or the spurious images of water on or above dry roads in the heat. \n\nSo it is definitely true, that the sun has already gone below the horizon, when we still view its image.

because the sun is in the middle of setting

Ha ha ha ha! Good God! It is only bad for your eyes if you are sitting on the roof of the vehicle while in motion.\n\nI don't know where that idea came from but to put your mind at ease, your eyes are constantly moving, and do so to compensate for movement of the body, when walking for example, other wise our vision would be like looking through a shaky hand held video camera. The same goes for when we are in a moving environment such as a car or a bus.\n\nI assure you that your eyes will not fall out nor will your hair grow curly if you eat the crust on the bread.

too much sand blowing around, plus with the direct sun, you wont be able to see your screen anyways.  i would not take mine to the beach.  \n\nplus, youre at the beach...watch the hot bodies instead!

Because your part of the earth is too far away from the sun.

Some people think it does. but really, the simple fact of looking up is opening your nasal cavities, making it easier for your body to complete the sneeze. It seems logical for people to try to make the connection between sneezing and looking at light... The sun and light are just making you squint when you look at it.

two factors, diffraction being one.  The other is that you rarely have a a small source.  The sun appears small, but is significantly larger than the Earth.  Therefore, on any edge shadow, you have light rays coming from both sides of the sun as well as the middle.  Since their trajectories are not parallel, the edge gets fuzzier farther away from the shadow because the rays are able to spread out more once they're past the actual edge casting the shadow.

The moon gets in the way of our view of the sun.  Since coincidentally, the two disks (i.e., two-dimensional view of a sphere) have the same apparent size when viewed from the earth, the moon covers most of the sun, exposing the corona, which is normally invisible.  The corona is the thinner part of the sun which is not normally visible because of the glare from the main disc.\n\nHowever, here's an interesting question:  how far out in space would you have to be before looking at our sun (call him Sol), you would just see a bright star, and part of that star would be the earth?  That is, when we say "the solar system" to include ourselves and everything out to Pluto, an observer from far out in space would just say "Sol," and mean to include us.  Jefferson Starship sang, "We rode a bubble through the sun . . ."

ALL direct sunlight is dangerous to your eyes. Try to leave work a bit earlier or later or take a different route to avoid it. Hope this helps.

Because we are really close to our star, the sun.  The light from it drowns out the other lights from stars.  The same way a very small light in a room is drowned out by turning on a much larger one.  At night, we are completely turned away from it, so we can now see other lower light sources.

u heard it wrong .. by the way have did u really hear it from someone.? how stupid can someone to say you something like that.\n\nIf they are pregnent, and if there is an eclipse they say it is not good to see the sun. and doesnt have to be religion thing it is scintifical no to see them

Not an expert, but it seems to be a kind of reflex action in a small percentage of people. If you experience the "sun sneeze" the same way that I do, it only occurs if I look skyward or toward the bright light of the sun.  If  I look away, I lose the urge to sneeze.  My best guess is that it may be a crossed wire of sorts in some people where an overload of the visual senses creates a reaction.  Since it is impossible to keep your eyes open during a sneeze, it could be that this reaction is the body's attempt to protect your eyes from exposure to the intense light.

Actually, just point you camcorder in the direction of the Sun, however, don't look through the camcorder.  When you see the video, the Sun can only be so bright and won't hurt your eyes as you look at the video.
