And God made the two great lights; the greater light (sun) to rule the day, and the lesser light to rule the night: he made the stars also.And God set them in the firmament of heaven to give light upon the earth,[Genesis 1:16-17]
Light means Life:"In him was life; and the life was the light of men. And the light shineth in darkness; and the darkness comprehended it not. [John 1:4-5]
The Importance of the Sun
The Sun is our supply of daylight. It is the enormous bright yellow circle that we see in the sky in day time.
Astronomy believes that the sun is one of the many stars in our galaxy, which the Earth orbits. It is usually thought of as the midpoint of our Solar System, because it is the only star in it (the solar system) which is also the only foundation of energy for the entire living thing on earth.
According to geometry, on one occasion the Sun is also in the centre because the planets go around on all sides of it. This is somehow vital in astronomy and in forecasting space travel. It is known that a spacecraft can actually surf on the solar wind (the particles flowing away from the sun out towards the system's edges)
Solar energy and photosynthesis drive life to reverse entropy, the reason that makes the green color of many leaves and plants; making order from less ordered molecules by creating more complex molecules, mainly proteins and enzymes.
Lately, life has been revealed on the ocean floor that depends on chemosynthesis, determined by energy still in the Earth from its configuration. Nuclear fusion and nuclear fission are used as a human energy source. Other than these, all life relies on the large-scale nuclear fusion that takes place in our Sun. On the surface, we can see it uniting hydrogen into helium, but it also obliges many other heavier elements mutually nearer its core. Not many might know this, the fact that we can't get close to that.
Sunspot activity may change the weather on Earth, in a round of about every 11 years. This phenomenon may also meddle with electronics.
Why do we need the Sun?
Why is the Sun so important to us? It had always been stationary up there in the sky and seems as though it does not give any good to some of us who cannot stand the heat of the sun burning on our skin.
Well, do not be fooled. The Sun is the prime source of the energy that we get from the food that we eat. Remember the food chain system that we have learned from Biology class? The Sun provides energy and photosynthesis that is needed for plants to grow. These energy that we get from plants are then transferred into us while we are consuming it.This also occurs when we consume on meat or poultry products. The energy that the animals might have consumed from the plants that they have eaten while they were alive would still remain in their bodies that would finally end up in ours.
As the cycle goes on and on, let us all not hope that something else might consume the energy that we currently have by having us on the daily meals!! :)
What would happen if the Sun never existed?
Here is a very interesting question. What would happen if the Sun NEVER had existed?
If the sun never existed, nothing in this world could have existed either. God created lives on earth for us to appreciate, and therefore please do cherish the gift of light and heat that is given to us in our daily lives.
Just imagine life without the ability to see the surroundings around us, and not knowing the existence of heat that we could feel right now; and worst of all, imagine not having the energy that we are supposed to get from the food that we eat. Seriously, how can there be life without the help of our friend, the Sun?
