How much does the sun illuminate the universe?

If you don't believe that the sun illuminates the universe, you will measure it yourself.

The sun belongs to the solar system, the solar system belongs to the Milky Way, scientists have discovered hundreds of billions of galaxies, and the sun is just an ordinary star, at most it illuminates the Milky Way, that is, one in a few billion, don't think of the sun as a god.

The sun is so insignificant in the universe that it seems big to us, but in the vast universe it is just a drop of water in the ocean, and if you want to use percentages, it can only be said to be percentages? , thinking that astronomers won't give you a precise answer to it. You're just idle and bored to ask, and I'm also idle and bored to answer.

Modern astronomy has shown through gravitational lensing, large-scale structure formation in the universe, microwave background radiation, etc., that the part we currently know only accounts for 4 percent of the universe, dark matter accounts for 23% of the universe, and 73% is a kind of dark energy that causes the universe to accelerate expansion.

And the sun is just a drop in the ocean of many stars in the universe, do you think it will exceed one percent?

And even one percent may not be enough.

First of all, the landlord's question is not how to be exact.

I don't think so.

If you count the mass, it's directly equal to 0

And how far can the light shine? Infinite, I guess.

Because the speed of light cannot reach the speed of the expansion of the universe.

At least that's what I think, there's too little that humans know

Even the size of the universe is unknown, so how can the percentage be determined? Think about it.

If a vase is broken, what is the ratio of the number of large pieces to small pieces, and how much, do you know? 1:64:64 square: 64 cubic: 64 to the fourth power: ... What's more, it's such a huge universe!

You're still pretending to be stupid! Photon energy is limited, and you're done with it when you're released! Besides, God knows how big the universe is! (Infinity?) Aliens know! ）

The sun illuminates the earth, why can't it illuminate the universe?

It's the reason for the distance.

The radiant intensity decreases inversely proportional to the square of the distance. The closer you get, the higher the intensity, and the more places you can illuminate. If it's too far away, it won't shine.

The universe is too big, just like a lamp in the house that illuminates the home but not the world.

1 part per 100 billion in the universe.

The human eye, as a visible light receiving device, is actually not very reliable, and it is easy to be deceived and misled, and the only thing that can really be used to observe the universe is the Hubble telescope, or the radio telescope array on the ground, because it can receive full-band electromagnetic waves, so that human beings can see the whole universe.

There are between 100 billion and 200 billion galaxies in the universe, and only the stars in the Milky Way galaxy can be seen, and the Andromeda Nebula (M31) is about 2.2 million light-years away, which is also the closest extragalactic galaxy. So the naked eye can only see about 1 part of 100 billion of the entire universe.

There are between 100 billion and 200 billion galaxies in the universe, and we can only see the stars in the Milky Way and the Andromeda Nebula (M31), which is about 2.2 million light-years away and is also the closest extragalactic galaxy to us. So we can only see about 100 billionths of the universe with the naked eye

Because the sun is very small to the universe, it does not have such a strong light to illuminate space.

As we all know, the only celestial body in the solar system that can shine is the sun, because of the existence of the sun, the earth has light and warmth, and because of the existence of the sun, Mars, the moon, Venus and many other planets are very bright in the field of vision of human beings

This is mainly due to the amount of energy, for the universe, the sun is too small.

Because comparatively speaking, the sun is big for us and small for the universe.

Because space is so big, the sun's light seems very small in the universe.

The Earth is too small for the Sun, and the Sun is part of space. The sheer size of space is unimaginable.

I think the main reason for this is that the energy is so small, so it can't be irradiated into space at all.

Other planets, they don't have any matter to reflect light, so we think they're all shrouded in darkness.

Because the space of the universe is too large, not every space can be illuminated by the sun.

Because the universe is so big, there is simply no way to illuminate it.

The sun is a tiny part of the universe.

The sun is still too small for the universe.

Because the universe is too big to illuminate it.

Because the sun is so small in the universe.

In the universe the sun is quite tiny.

Because the sun can't shine into every corner of space.

How big is space, how big is the earth?

The universe is still too small.

Because there is nothing in the sky that reflects the sun's rays.

A matter of distance. What a big black hole space is. The sun simply can't illuminate all of space.

There is no air in space, no dust floating in the air, nothing reflects the light, so it is dark.

Light is particles, and particles are reflected back like a mirror.

Because space is endless, there is no way for a single sun to illuminate.

Because space is infinite, there is no way to reach the sun's illumination.

Because space is an endless black hole, much bigger than the sun, and there is no way to illuminate it.

There is dark matter in space that can absorb sunlight.

Because there are so many stars in space that are easy to occlude.

In the big picture of the universe, the sun is too small.

Because the sun itself is a big fireball that glows and heats, and the earth is not.

The earth has light and warmth, and because of the existence of the sun, Mars, the moon, Venus and many other planets are very bright in the field of vision of human beings

Compared to space, the sun is only an insignificant part. There are many stars that are much larger than the Sun.

Because the sun's rays are not enough to illuminate space, the Earth is very small relative to the sun, so it can be illuminated.

Because the Earth is really too small relative to space, it can illuminate the Earth.

Because the universe is so big, even the sun can't illuminate the whole of space.

Because for space, the sun is still very small, and there are a lot of dust obstructions in space.

The Sun is just relatively large in the Milky Way and is not worth mentioning in the entire universe.

3. The sun itself is a simple star, so it is a subtle existence relative to the universe. I have to say that our universe is a huge system, and within this huge system, the solar system is one in a thousand, so it is precisely because of this that the sun in our eyes is very huge relative to the earth, but it is very small relative to the universe, so it is difficult for the sun to illuminate the universe.

In general, the sun is very huge relative to the earth, and it is precisely because of this that the sun can illuminate the earth, but compared to the entire universe, the sun is only one of the many stars in the huge system of the universe, so in the entire space of the universe, the sun is also a very small existence.

Isn't it obvious that the sun with a big plate becomes bigger at noon, and the sun is sometimes near, sometimes far away, but don't worry about illuminating the earth.

The sun is so far away from us that it's so small, but it's surprisingly big.

He's the core of the solar system, and the stars emit light, and the mass accounts for 99 percent of the mass of the solar system, and it's more than a small plate.

Why only the solar energy that is the size of the disk illuminates the whole earth, it is because you are too lucky to be too lucky from the sun and visually feel that the sun is only the size of the disk, but in fact the sun is thousands of times larger than the earth, and the sun is bigger, so it can illuminate the whole earth.

The sun is too far away from the earth, and it is only the size of a plate on the earth, but it is actually much, much bigger than the earth.

Because the plate in your eyes is actually a few times the size of the earth where you live, but it is too far away, light years away, it naturally seems small.

If you don't take it down, no one can say for sure, once I took a bamboo pole on the top of the west mountain, and wanted to wait for it to fall down, but it still floated overhead.

In fact, the sun is 3,700,000 times larger than the earth, and it is only because of the distance that the size of the sun's disk is seen on the earth.

Because you look at it from a distance, you think it's small, but in fact, the sun is not small, the sun is a big fireball, the energy is huge, and when it burns, it releases a huge amount of energy, so it can illuminate the whole earth.

The question you are talking about should not be a problem, if you want to describe a beautiful scenery clearly, you need to take a certain logical order, from far to near, from high to low.

What you said is really interesting, the sun is not only the size of a plate, but it is only because it is far away from our earth and has a sense of distance that it is what you seem. So it's normal for the sun to illuminate our earth!

The sun is not only the size of the plate, the sun is n times larger than the plate, and the earth feels that the sun is small, but in fact the sun is very big.

The reason why I think it is a ** son is because of the distance, but in fact, he is much larger than the earth. His light was very, very strong.

The sun is not just the size of a plate, the surface of the sun is thousands of degrees, and the sun is made of gas!

Are you sure the sun is only the size of a plate? In fact, its irradiation power is still very awesome, so it can illuminate the earth and the whole earth.

That's because the sun is so far away from the earth, and the visual effect you see is like if you were making an airplane, at a certain altitude, you can see that the people below are about the size of ants.

The sun is the size of the plate, just what we see from the earth. The sun is a huge fireball, and it is bigger than even the earth.

Everyone in the universe knows that there is not much air there, and there is no medium that can reflect light, so the sun's rays are very faint on other planets. And according to the speculation of scientists, the universe is constantly expanding infinitely with time, and the sun, as a star, emits very limited light, which can illuminate all the space on the earth, but its light is very small in the entire universe.

Because nothing can block the sun's rays, it can hit the surface of the earth or even cover the entire earth.

The sun looks like it's the size of a plate, and that's because we're so far away from it.

It's because the sun is very big, but the sun looks like the sun from the earth to the naked eye, and it's only the size of a plate, but the real sun is about the same size as the earth.

The sun is the size of the plate, you are writing a fairy tale.

Only 1 in 2.2 billion solar radiation reaches Earth.
