"Computers don't have infinite precision, meaning they can only store up to a certain number or decimal points. So for pi, that's something like 15 digits (in that ballpark). Calculating the square root of 3.1 is no more difficult than calculating the square root of 3.14159 as far as the computer is concerned........ | [

If air is made up of millions of molecules, why can we see through them? | [
"Sight works on light reflecting off of a surface and stimulating receptors in your eye that convert these stimuli into a signal that your brain can understand. These molecules do not reflect enough light for the receptors in your eyes to be stimulated."
] | [
"It's a little heavier, but not much. Kinda like dust floating in the air. Dust is heavier than air, but it's still so light it can float on the slightest breeze for quite a while. Natural breathing mixes up the air so it doesn't really have time to settle, as does the wind outside."

How are allergy shots and homeopathy different? | [

Why not instead of going after illegal immigrants the U.S doesn't go after businesses and people illegally hiring them? | [

How is it that we can capture light from the early universe (hubble) when we are no longer a part of the early universe. In other words wouldn't light from the early universe be "ahead" of us? | [
"Because the light that we capture comes from really far away. That means that it started its journey a long time ago. Basically, we can't capture light that is *both* from the early universe *and* from near us. It has to be from *far* away, and that automatically also makes it from *long ago*."

"It is \"observable right now from earth.\" It takes light time to travel. If thigs in the universe are so far away that they haven't been in existance long enough for their light to get to us, then when we look their direction there is nothing to observe.
