Why do people say it’s dangerous to look at a solar eclipse? Well, in general, you’ve probably been told not to stare at the sun. This is because the sun simply outputs more power than our eyes are designed for and exposing our eyes to that kind of power can damage the retina. In a nutshell, solar eclipses are dangerous because the sun can come out from behind the moon and “surprise you” before you have a chance to look away. This is actually even worse than when you normally look away from the sun because during a total eclipse, it is dark and your pupil, therefore, dilates, to absorb enough light to get a good picture. When the sun reappears and starts flooding the area with really bright light, not only are you staring straight at it, but your eyes are wide open and actively trying to absorb as much light as possible.

In a nutshell, solar eclipses are dangerous because the sun can come out from behind the moon and “surprise you” before you have a chance to look away. This is actually even worse than when you normally look away from the sun, because during a total eclipse, it is dark and your pupil therefore dialates, to absorb enough light to get a good picture. When the sun reappears and starts flooding the area with really bright light, not only are you staring straight at it, but your eyes are wide open and actively trying to absorb as much light as possible.

By design, a light bulb does not contain oxygen. The manufacturer fills it when an inert gas like argon or nitrogen. However, this does not prevent atoms from popping off the surface of the filament due to the intense heat. This makes the filament thinner and thinner. Eventually, it becomes so thin that it breaks. For a short period of time, the two broken ends are very close to each other and electricity can jump across in a bright blue spark. However, the two broken ends soon fall away from each other, breaking the spark, and the bulb will die.
