is it true that the space is dark and sun only light for us and thats why we see the sky blue?

Answer 1

The sun just light the solar system.its a star and there hundreds of others lighting their own Planets

Answer 2

Outer space is relatively dark but there is light from distant stars and even some light left over from the Big Bang that has not yet been absorbed. The sun supplies most of our light even at night when it reflects off of the moon and planets. However, the sky is blue during a clear day because the atmosphere absorbs or scatters most of the light except the short waves of blue that are very penetrating. Most of the light that reaches your eye is blue. At sunset, most of the light (traveling a longer distance through the atmosphere at an angle just above the horizon) that reaches your eye is red because the rest is scattered or absorbed by dust. Hope that helps a little.

Answer 3

Yes, that is indeed true. If the space didnt have any Stars/Suns in it, it will be just an endless limbo. The sky appears blue because all of the 7 colors have wave lenghts, the sun gives white light, which is made of the 7 colors. Now since blue has the shortest wavelenght, the sky appears blue.

And if you want to know the sun produces light and heat by converting Hydrogen nuclei into Helium by thermonuclear fusion, which is done at the core of the sun....which has a temperature of 4,000,000 Degreese Celcius. Its surface on the other hand is 4,000 to 5,000. The Life-span and temperature of a star/sun varies by its size.

And since we are on the topic of light, something interesting about it. Light has something called "the double truth of light".
As you might already know there are WAVES and PARTICLES in the electro magnetic spectrum. Waves travel in wavy paterns, while particles travel in a strait line.
Now light is a particle, but travels in a wavy patterns, so it has the properties of both.

Hope this has answered your question =D

Answer 4

First you need to understand that light is only seen when reflected or when directly looking at a light source (sun, candle etc) therefore if you were far away in space holding a torch light and you turn it on, you won't see the light apart from the small bulb in the torch itself.

You are correct, since space is not material, it doesnt reflect light and therefore appears dark otherwise we would not be able to see anything at all because of the background light reflected off space.

Sky blue is a totally different issue. It has to do with water droplets in the atmosphere and refraction of light of the sun by them.

Answer 5

YES. The space is empty. LIGHT IS ENERGY. THis means that when light is on space, that space is not empty already because there is light.

DARKness is only a sensation we perceive due to the absence of light. Just like emptiness is the absence of anything. WE DON'T SAY THAT that there is darkness in space. Rather, THERE IS NO LIGHT IN SPACE.

LIGHT IS A FORM OF ENERGY that our eyes can sense and our brain can interpret. WE SEE THE SKY IS BLUE BECAUSE BLUE IS THE COLOR OF LIGHT that is scattered most during the day...

ACORDING to HEWItt, ligh is the only thing we can really see...

Answer 6

The sky is blue because the light from the sun gets scattered in our atmosphere. The sun is bright for all the inner planets (although it is a fairly dim star compared to other stars).

Answer 7

Light is "invisible". You only see light when it bounce of or hit something. Shine your torch towards a wall, and you "see" the round spot of light. But you do NOT see in-between.
When the photons sent by the lamp hit the wall, a certain amount of them bouce back and hit your retina, which contains receptor sensitive to photons, the "grains" of light.
So, yes, the space is dark, because there are no object that can be hit by photons. But you see the moon, because it is hit by photons that bounce back to your retina, again.
This is not why we see our sky blue...
It is blue because oxygen filters the sun-light and scatter different wavelengths of light, and the blue is the best dispersed for us to see.

Answer 8

Yup. Absolutely true.
