Sure, the sun is powerful, but it's 93 million miles away.
Get up 20 miles and out of our atmosphere, the sun would be very bright to look at, if you're looking at it, but it's blackish if you're looking away from it. What makes it light up the whole sky for us here on Earth, though, is that very same atmosphere. The gases in the shell around the Earth trap the light in.
Think of shining a flashlight in a very dark room. If you look at the light source, it's bright, but everywhere else in the room would still be pretty dark. Now shine the same flashlight into a box with mirrored panels on the inside. If an ant was in the box (a person on Earth), it would seem bright to the ant inside because of the reflected light off the mirrors (the atmosphere). Rotate the box away from the flashlight and it would seem dark to the ant (night time).

This will make you feel small... In the vastness of space there isn't a single star powerful enough to light the whole universe.
If you stood in the middle of a dark stadium and lit a match do you think it would be bright in the nosebleed seats? No there isn't enough light put out by the match to fill the stadium.
Also, you have the speed of light to deal with. Light just doesn't travel fast enough to light up the universe during the life time of a star. And once the star does "burn out" you have darkness filling back in right behind the light.

well...how can i explain...there isnt really any light going through space at all (meaning even if the sun's light hits something, that certain something muct reflect the light instead of just absorbing it) ok ill put it in an easier way, if you are wearing a blue shirt and ROYGBIV (or colored light) hits your shirt, you are able to see the blue because everything else is being absorbed while the blue reflects. im guessing thats the same with the sun, if it doesnt reflect any color back, you will not see any color at all. (i hope this helps a little ^_^)

Photonic pressure from other stars is applied to the light from our sun. There are "sweet spots" in space where the light is just right, other places are dark or too light.

In space, there is nothing for the light of the sun to boune off of. The light continues to flow on and on, but if it doesnt bounce off anything, we don't see anything...
We see daylight colors and objects because the light emited from the sun bounces off the objects we see...
If we were in a room sealed off from all light, we would not be able to see anything, because no light would bounce off objects and be recived by our retnias in our eyes...

It does. There just is nothing in space to reflect it, except the occasional dust speck.

Something has to be there to reflect it! Otherwise the light just keeps going.

There's nothing for the sun's ray to bounce off

some of the light is absorbed by space debris.. dust.. gas.. etc.
