We know that the universe is huge and has billions of stars there. But if there are many stars that are much bigger than the sun, why is space dark and black?

Even though the question seemed easy, the answer wasn't as simple as we thought. The reason why dark outer space turns out to be related to the vastness of our universe. How is the story?

So, there are about one hundred thousand million stars in our galaxy and a trillion, or one zero zero zero zero zero zero zero zero zero zero zero zero zero zero zero zero zero zero zero stars in our universe.

Yes, the number of stars in our universe is very large, but the problem is, the stars in our universe are actually very far apart and not all of them can be as close as the sun to give us light as strong as the sun. Imagine this as if we had a flashlight when viewed up close, it could look bright. But when viewed from afar, the light is dim. Then, now try to imagine that starlight is like a distant flashlight. But the difference is, their light is so far away, it takes millions of years to travel just to get to earth.

But actually it still hasn't answered fully because the fact is even more terrible. Apparently, our universe is not only very broad, but also expands and continues to grow. What is this thing? And what does this have to do with the darkness of space?

Okay, instead of using complicated language, imagine like you have five kilograms of sugar and count every grain, that's really a lot right?

In the beginning our universe was also this dense. But now try spreading sugar on a black plate. Then, try yesterday to the black dining table, after a while the sugar granules go further and the sugar looks smaller right?

now try to imagine your sugar spreading to fields the size of a stadium where grass is painted black. Yes, your sugar will be very small, hard to see, and only become white spots on the broad grass of the stadium. And, that's the Big Bang theory, which found that our universe continues to expand, maybe even a thousand times that of the stadium field. Over time, stars that are too far away will no longer be seen. And maybe, the time will come when there will be no more visible stars from the earth that will make our night sky really dark.

So, even though our night sky is not as black as delicious soup, but at least we are grateful for the stars we can see now, before finally, maybe they disappear from our sight forever.
