JAKARTA- This is the reason Paradise the dark at night will be interesting to review. You might think there is a simple answer to this question, does the night sky have to be dark because the sun has already set? But is not so.
This started thousands of years ago, scientists had been asking for the same thing. The answer is not that simple.
Why is the sky dark at night? Find out the answer in the following article: During the day the sun enters the earth’s atmosphere and illuminates the earth. The earth rotates, the sun no longer illuminates some parts of the earth. This is why some countries of the world are dark at night.
If the universe is so vast and infinite, shouldn’t we be looking at the stars? Since there are many stars and other celestial bodies in the universe. We should be able to see through a telescope.
Many ordinary people think that billions of stars and celestial bodies should be able to light up the night sky. So reaching the sky is it still dark?
Keep in mind that the speed of light of space objects with the universe has a very significant age. So the sky looks black and dark. Objects in space cannot fully illuminate the universe.
Meanwhile, the darkness of the universe is affected by the electromagnetic spectrum. The true absence of light is because light cannot be detected by the sense of sight. Given the distance, the stars are quite far away. Therefore, the reflected light is not enough to illuminate the universe.
LAPAN Science and Space Center researcher Andi Pangerang said that what we perceive as color is the electromagnetic spectrum. Light is reflected from our eyes.
There are several wavelengths of the electromagnetic spectrum. Both the visible and invisible spectrum of light can be seen by the human eye.
This middle spectrum of the universe is said to be the cosmic spectrum. The dominant color of the cosmic spectrum is perceived by humans as the dominant color of the universe.
This is why the sky is dark at night. Hopefully, it can add information about the universe.
