why doesn't space have daytime?

Question

you know how here on earth we have daytime and night time well if space is closer to the sun then why doesn't space get light out?that is the question of the century i think

Answer 1

It's always daytime in space. Unless you are stuck behind a planet or a moon or something else, then it's dark as hell... The spining of the Earth creates day and night.

Answer 2

If you were out in space in orbit around the sun at a distance similar to that of Earth's, you would find it extremely bright. Astronauts who spacewalk have to wear tinted visors, or they will go blind from the bright solar rays. It is actually brighter up there than it is down here, because down here the atmosphere absorbs a lot of that light before it gets here.

However, if what you mean by that is, why isn't space "blue" like blue skies, that is because Earth's atmosphere diffuses the incoming light, much the same way the plastic covers on fluorescent lights spreads the light out from the fluorescent tube. It diffuses into a blue hue, because the atmosphere itself has a bit of a blue tint.

Answer 3

1). The idea of night and day.

It might seem strange, but on the Earth day and night happen both at the same time. While it is daytime on one half of our globe, there is night on the other half.

It happens so, because what we basically call "day" is, in fact, a phenomenon of the sun shining on one side of the Earth. Let's make a small makeshift model consisting of our sun, Earth and the rays the sun sends.

(W/E)========(.....Sun.....)

Earth Sun Rays Sun

W means Western hemisphere
E means Eastern hemisphere
/ is the axis of the Earth (which is inclined under the 23,4° angle)

As the rays fall on the Eastern hemisphere of the Earth, in Russia (which lies on the Eastern hemisphere) it is day. On the other hand, as the Western hemisphere is on the other side, and the rays do not fall on it, there is night in, say, USA (which lies on the Western hemisphere). But, as the Earth rotates the hemispheres change their places:

(E/W)===========(....Sun....)

Now it is daylight in USA, and night in Russia.

2). Day and night on Earth, and the Space
As we saw on those simple makeshift schemes, the day and night take place because of the rotation of our planet. But where is space in this scheme? Well, everywhere else. Space is to Sun NOT as Earth is to Sun, but as a fish swimming in the middle of the Ocean is to Ocean (although the scale is wrong... or it should be an extremely small fish...) You can't be close or far from space. Your IN IT! So is the Sun. So is our Solar system. So is our Galaxy.

What is space then? Well, to put it in the simplest way, it is a huge vacuum well... space (in the sense of room here). Well, not exactly vacuum. There are stars, some with solar systems like ours (yes, planets. A few weeks ago Poles detected a planet around a different star. Apart from that we can proof existence of planets around other stars by tracking the changes of the star movement - it moves across the space in a slalom instead of a straight line. But that's a different story.) and lots of other stuff (comets, pulsars, black holes, asteroids, neutron stars and lost of others), whole galaxies soaring across it. But between them, there is vacuum. Now, another thing that has to be straightened out is, that our Sun is a star. It looks so big in comparison to ther stars because we are so close to it (and as we all know objects that are further seem to be smaller), and, being a star, it's not too big really.

Now, trying to light the space is more or less like going to a shore of the Atlantic Ocean and pouring a glass of a cherry juice into the waves in hope, that it will make the whole water taste of cherries. And that is because light is made out of photons, which are, well a kind of particles. And even if the sun produces them every second, it's impossible to make enough of them to make something that would reassemble a day because:

1) The space is infinite. In it's beginning, as the theory says, it has blown up out of a point of an infinite mass in vacuum, and as you know, when something blows up, there is an explosive shock wave, which has a lot of energy, and can push things away from the center of the detonation (I bet you often saw in a movie a good guy blown off his feet by the explosive shock wave of a bomb explosion, while running away from the place where it was planted). Well the "Big Bang" - as scientists call it was so strong, that it threw the whole matter with such a force, that it is still going on (our galaxy too). Yes, the space is still expanding, still growing, so the sun would have to make the photons much much faster to brighten the universe, and basically, even if all the stars would, they all taken together do not have enough fuel to make enough light to lighten the entirely space even for a fraction of a second. But they can make enough to be visible on the night sky (or to make days on their planets). Like with the juice. When you pour one glass of it into the Ocean, it will give an impression of sweetness to a bypassing fish for a fraction of second, but then it will mix with the rest of the Ocean waters. And although you can pour another glass to make it sweet again, you have not enough money to buy enough juice to make the whole Ocean change its taste.

Answer 4

on earth we revolve around the sun on part of the earth is facing away from the sun it appears to be night time because so much less light is getting to it
in space there are no significance light changes so it is the same all the time

Answer 5

because space is as far as we know infiniant. there is no end to it and theregfore it has no rotation around any set point like earth does. earth has day ad night because of the spinning on its axis. space is both closer and further from the sun as we know it. if you try to imagine space as a whole you will blow your mind because infinity is impossible to comprehend.

a better question is a conversation me and a friend has about anti-matter and the existance of a paralell existance and what and where and how it would be effected by our daily lives or how it effects our daily lives.

Answer 6

Well....open space doesnt have anything for the sunshine to fall upon, therefore it just passes through. If you were there, say in a spacecraft, there would, indeed, be "daylight." It would fall upon you and your craft anytime you were not blocked from the sun by a planet. So, "day" and "night" wouldn't be relevent, but you get the idea.

Answer 7

Well i think it does it just depends where you are in space. If you can physically see the sun if your in space then you have light also depends how far you are away from the sun.

Answer 8

Because in Space you're not rotating around the sun as our earth does when you are on it

Answer 9

Depends where in space you are.

Time does not exists, it is for our convinces, go on web and read hope diaries
