Because we can't perceive the length of time that light takes to cover any distance
that we can watch.
Example:
Let's say that we can tell the difference between two things that happen 1/100 of
a second apart. In that amount of time, light travels 1,863 miles, like the distance
from Seattle to Houston! We can't even see two points that far apart at the same
time.
Another example:
So let's work it the other way. Let's say that we get up on a mountaintop, and from there,
we can look down in the valley and see two places that are 20 miles apart. There's a giant
flashlight at one of those places, and a giant billboard at the other place. Can we see
the time delay between when the flashlight turns on and the billboard lights up ?
Not likely. Light covers 20 miles in 0.00011 second.
(And don't forget the time it takes for you to see the flashlight after it turns on,
and the time it takes for you to see the billboard after it gets lit up. If the two
places aren't layed out just right, you might actually see the billboard light up
before you see the flashlight turn on !)

What is special about the speed of light?
you cant see it
Why you cant see visible light?
If your vision is normal, then you CAN see visible light.
If a black hole can suck-up and draw in light then the speed of darkness must be faster then the speed of light?
Not quite. Remember that darkness is simply the absence of light. If you flipped a lightswitch in a closed room the light turns off, and it goes dark. The reason that is is because the lack of a light source. Some animals can take that lack of a lightsource and see using infrared visuals. They DONT emit a red light so darkness is still set there, but they can see through the darkness. The reason this is, because darkness is just a state of no light. We see things because light reflects off of them. The reason blackholes suck light is because they are so powerful light cant escape. which means light cant emit. Darkness has no speed esentally that is what I am getting at.
Why cant you see your reflection in all objects that replect light?
You cannot see your reflection in all objects that reflect light because of diffuse reflection.
Is there a point when velocity cant get bigger?
Yes - the speed of light. Nothing exceeds it.
Can crickets see red light?
no they cant, because crickets can only see black and white light.
Can light go faster then the speed of light?
Since light is made of light, whatever speed it goes at is what we call the speed of light. So we'll always see light moving at exactly the speed of light, at least in that particular medium.
Why cant you see beams of light in space?
there are no particles for the light to bounce off of
Why is an approaching asteroid or meteor might not detected right away?
because its so far away the speed of light cant see it so we would only be able to see it 5 years later.
What are 2 forms of light that the human eye cant see?
infrared light and ultraviolet light
Why cant you see red colour in diffraction grating experiment?
as red light refracts at bigger angle we cant see it
What is a material that light can't travel through?
light cant travel through opague materials, or anything you cant see through.
