A person is so used to the change of day and night that he already accepts this phenomenon as ordinary. However, how many interesting questions can arise in his head if he rejects the usual opinion and tries to look at the world from a completely different angle. Indeed, in reality, earthly night is an amazing phenomenon that has given rise to many laws.
So let's go on a short trip through our universe and finally find out how unique it is. In particular, let’s talk about exactly what role night plays in the life of our planet.
What is night?
Night is a physical phenomenon caused by a partial absence of light. This happens because the Sun is on the back of the planet, because of which its rays do not fall on part of the surface of the Earth. The funny thing is that even at night our planet is not devoid of all the light, otherwise people simply could not see anything beyond their nose.
It should also be noted that night is a rather relative phenomenon. Its duration can vary greatly depending on the time of year and geographical location.
What could be the night?
So, as mentioned earlier, night is an amazing phenomenon that has many forms and types. The simplest example would be the presence or absence of the moon and stars in the sky. However, there are nights that are completely different from others that can enchant a casual spectator.
So, the most beautiful is the polar night. At the edges located in extreme latitudes, twilight is much longer. At times, dusk can last a whole day, only occasionally retreating over the horizon. But it is fascinating that precisely at such moments here you can see the northern lights, illuminating the sky with hundreds of different colors.
The exact opposite is white night. So, in temperate and high latitudes during the summer solstice, even at midnight, the world can remain as bright and clear as day.
Night is the time when all living things are resting
But let us leave physics behind and talk about what night gave to all living things on the planet. After all, it was during this period that almost all organisms used to rest. Naturally, there are those for whom darkness is the best time for action. However, for people, the arrival of night is a call to sleep.
Just think about how important this vacation is for us. The whole burden of responsibility for decisions made during the day is washed away by nighttime sleep. Not to mention the fact that it is she who removes the heat from the streets that comes to us during the sultry periods of the year.
Given all of the above, one can safely say one thing: night is an amazing phenomenon that must be perceived as a gift from above, and not as an everyday occurrence.
