what are the causes of invisibility?

Question

why can't we see some things?

Answer 1

shhh

because we want to see them or fear to see them

see what I want to see

not to mention we might not know what to look 4

Answer 2

Scientifically you need light to see objects, as darkness approaches the first thing that are hard to distinguish are colors, may sound silly and obvious, but without visible light we cannot see things with the limited wavelengths we percieve. Infrared cameras see reflected heat, some telescopes see in the x-ray spectrum. our vision percieves just a small amount of what is out there.{at this point in our human evolution.}

Answer 3

Microscopic things. But the US has come up with a thing to make you invisable, it bends the light around them so it looks like theres nothing there, but its actually just bending around and back in place.

Answer 4

There is only one cause of invisibility - lack of detectable light emanating from what ever you are viewing.

Answer 5

Some things are too small, some are well hidden. That simple.

Human eyes can only resolve to a certain size. Below that, there is not enough light reflecting off to excite our rods and cones.

Answer 6

Because of the limits of our eyes and minds!! There are a lot of species out there that can see a heck of a lot more than we ever dreamed of!

Answer 7

Huh? What is it you think your not seeing. The only thing we don't see is God because were faithless and don't know how to manifest him. Although I hear there is technology that covers a car all over that makes it appear like a mirror using light to reflect the things around it so you don't see it. There goes all are privacy, pull your shades people!!!

Answer 8

lack of passion. passionate things, people, situations are hard to not look at.

Answer 9

cause we don't need to. We're built to see what we need to see.

and sometimes our eyes are just closed.
