Science, asked by veedushee, 1 year ago

In space there are so many shining objects like sun , moon , stars and soon but still space is black. why ???


2005harsh: See imagine that you are in a empty room and lights are turned off and there is no source of light and you are not told that where are you then you can't tell anyone else that where are you. But if we turn on the lights then you can see that you are in a room. So the thing to be noticed here is that when you was able ro see the walls then you said that it is a room otherwise you can't.
2005harsh: Like that if you cover the walls by a material called VANTABLACK then you would unable to see walls because vantablack absorbs all light and won't reflect it.
2005harsh: So, that means the side of universe absorbs light and won't reflect it to your eyes which makes you feel that its black.
kapilch: harsh your answer is v good
2005harsh: If you don't know about VANTABLACK then just search it on YouTube. And see a video. Vantablack is the worlds human made darkest material which absorbs 98.9% light and don't let you to see it.
2005harsh: Thank you KAPIL

Well, this is a good question;

When I was in 7th or 8th I too doubted this matter;

So, to understand this question well, we'll need to think about the size of the space or the universe.

Space is entirely a vacuum, that means there is nothing, except the Planets, stars and many other celestial objects

And now, Why is space black, even though there are stars??

There can be 2 reasons;

First can be that as space is vast and the star's light is very dim as compared to the size of the space. E.g., Take a very big hall, then turn off all the light source and try turn on just a small led bulb.

What will you notice?? Yes, you will only able to see a small dot may be a few things, but then also the room remains dark...

And, space looks black because there is no nearby bright source of light, like the Sun, to be scattered

But In space, there are many stars... Yes, there are many stars and other light sources. But the size of the space is much much bigger than that of the hall.

In combined we can say the sky may not be bright with the visible light of all the stars is because when a source of light is moving away from you, the wavelength of that light is made longer. This means that the light from stars that are moving away from us will become shifted towards red, and may shift so far that it is no longer visible at all.

And the second reason can be that space doesn't have an atmosphere, so, the light doesn't refract through anything. and we can see any light.

Before going into the questions read this

The Scientist is more interested for the discussing the end rather than the origin of the universe There are hundreds of is riddles for such thing that why the space dark even there is lots of stars, moon, and sun that can end life on Earth, the meteoric rise in Russia last year is one of these different possibilities. But it is a bit difficult to think of the end of the

Let us have a Example:-

If there are 20 hours in a area if there are no light except a single torch they that's why they don't get light sufficient,Same as this the huge muti-universe dosnt get enough or sufficient light from the sun, moon, stars.

We might think why the planets are getting the light from the sun because the reason the sun is hundreds of hundreds times bigger than our earth and it is having a huge radiation of light and heat hence our earth get enough light and heat energy.

Read this point to know the reason

But the reason that the space is dark but most scientists says that the star light and moons light is less and but the area of the universe in not defined we know planets, Galaxies, universes, and even muti-univerises but actually no one knows the space hence the area of space the light is not sufficient and it is really dark Frully dark this reason

You could see in the attachment image that there are lots of galaxy but there is no brighter light to the universe a huge place where all living and no-living scientic plz of planets, galaxies.
