Why does the sun go down? That may already be a question within you.
In fact, the answer to that question is very easy. According to science, the Sun can sink due to the Earth’s cycle.
As a planet, the Earth where we live is constantly moving. While the sun just stays where it is.

The Reason Why The Sun Sets Every Day
The sun is the largest source of energy on Earth. The sun always rises and vice versa every day.
When the sun goes down, the Earth will enter the night phase. This phenomenon can actually be explained in detail by science.
The sun can set because the Earth is constantly moving. The Earth does this because it moves around the Sun.
This movement is called revolution. However, the process that can cause the Sun to rise and vice versa is the rotation of the Earth.
What is rotation? Rotation is a process that the Earth does in the form of rotation on its axis continuously.
Earth will rotate to the east. That way, of course, there is always a part of the Earth facing the Sun and there is also the back of it.
The part that is facing away from the Sun will become night and it will appear as if the Sun is setting.
Instead, the region facing the Sun will be daylight, from which the Sun seems to rise.

Earth Rotation Time
The rotation that the Earth does, of course, doesn’t just happen. Earth takes time to complete one rotation.
The time it takes the Earth to make one rotation is 23 hours 56 minutes and 41 seconds. However, the time is rounded up to 24 hours in one day.
The Earth’s rotation is actually very important for life on Earth. In addition to being the reason why the sun sets, the rotation of the Earth also affects ocean currents.
Why Can’t Humans Feel the Earth’s Rotational Movement?
If the Earth keeps spinning, then why can’t humans feel it?
The rotational motion of the Earth cannot be felt by humans because we do not have the organs to feel the actual speed.
Humans are only able to know relatively fast or slow if we see something as a reference.
Fun fact, according to Starchild by NASA, people living on the equator are moving 1,600 kilometers per hour as a result of the Earth’s rotation.
The speed will decrease further if its position is getting closer to the Earth’s axis at the North Pole and South Pole. In southern Canada, the speed of movement is only about 1,000 kilometers per hour.

In comparison, if you are moving in a car, you need a speedometer to know its speed. Without a speedometer, we can only estimate the movement the car is making.
That’s what happens when the Earth rotates, which is the reason why the sun goes down. Everything in this world can be explained through science, including the phenomenon of the Sun rising and setting that occur every day. (R10/HR-Online)
