why is space dark, when the sun is up there?

Answer 1

nothing for the sun to reflect on

Answer 2

Light travels at the speed of light (300,000 km/second), which is way faster than we can get going.http://www.newton.dep.anl.gov/askasci/phy99/phy99067.htm
Space is quite vast and has no atmosphere to speak of because its gravitational pull is so weak due to its vastness, ....
With no atmosphere and gravity to hold anyting too close together the light just keeps speeding by until it hits something and is reflected or refracted, in which case it just starts speeding off in another direction ,,,,, so the moon gets hit and irradiated, so do a lot of the planets and earth (with it atmosphere and particulate molecules in the atmosphere, light is reflected and bounced all over the place on the side facing the sun, but not onthe other side, because it never hits that side and is never reflected.) The dark side of the earth, the moon, and the planets is due to the fact that travels in a straight line and reflects back in a straight line. Unless it is reflected you don't see it, because it is going away from you at the speed of light.
Lots of objects are "lit" up in space, but since there isn't much inbetween the big objects, like planets, astroids, comets, ... there's not much reflected light or heat or anything. That is why there isn't much sound in space either and why it is considered more or less a vacuum, or in other words, by its very definition space is empty and has nothing to contain any type of energy.
Or something like that .....
Which is why we buile telescopes which can capture as much light from as far away as possible, thus seeing things that happen before the earth existed maybe.

Answer 3

The expanse of space is beyond human comprehension. The bright stars are suns in other galaxies. Every large place has light and yet that light cannot cover the darkness of the space. And so is space. Space is as large as your imagination, and as the Italian singer Andrea Boccelli sang "quanto e grande questo cielo; quanto spacio c'e qui dentro mi, e' ci sara adesso so che mi vuoi cosi anche tu"

Answer 4

Space isn't dark, it only appears dark in reference to the stars and our sun shining in it

Answer 5

It's only dark when you look away from the Sun. If you look at your surroundings or yourself, you get the light that's reflected, that is of course you're on the far side of the moon.

Answer 6

same reason the night sky is always darker in a town, than in the countryside..
the light from a street light, throws out a "dark"-light shadow, the suns radiance has the same effect on surrounding space!

Answer 7

There is more space than light can fill... it's like asking why a candle won't make a dark room in the night bright as well.

Answer 8

Nothing to reflect off. Thats why the astronauts wear the very heavily coated reflective visors on their spacesuits.The light coming off the space shuttle is actually blinding,as there is no atmosphere to diffuse the light.

Answer 9

The nitrogen in the earth's atmosphere scatters the blue part of the sun's spectrum which is why the sky appears blue. Without scattering the sky would appear black.

Answer 10

Because there's about a jillion times more empty space than there are stars (the sun is a star)
