Today i’m here to talk to you about one of the most amazing subject in this world , one of subject that i personally believe that we should take care of it much more .
Today I’m here to share my ideas with you about astronomy
well what first come to your head when you hear the word astronomy , some of you will answer , planet , sun , earth , the moon , … and some other people -who confuse astronomy with astrology – will say the horoscope , first at all let me clear this astronomy is a science basically it can be considered the mother of all science , while astrology is just some old practice that have nothing to do with science .
well a lot of people will say , what’s a boring subject , ASTRONOMY !!!! what’s so special about that, well let me tell you what it’s so special about that , has you ever look into the sky by night and see all that light bright and beautiful , did you ever wondered where this light is comming from ? how does stars bright ? did you ever asked why it’s dark by night ? did you ever wondered how big is the univers ? did you ever wondered are we alone in this univers ? how life started ? all these question and much more other deeper question are answered by astronomy ,Astronomy is a science that seeks to explain everything that we observe in the Universe, By studying the cosmos beyond our own planet, we can understand where we came from, where we are going, and how physics works under conditions which are impossible to recreate on Earth. In astronomy, the Universe is our laboratory!
secondly , astronomy is the oldest of the natural sciences: nearly the earliest records that we find in the annals of China and upon the inscribed “library bricks” of Assyria and Babylon relate to astronomical subjects, such as eclipses and the positions of the planets. Obviously in the infancy of the race the rising and setting of the sun, the progress of the seasons, and the phases of the moon must have compelled the attention of even the most unobservant.
As Astronomy is the oldest of the sciences, so also it is one of the most perfect, and in certain aspects the noblest, as being the most “unselfish,” of them all
by understanding all those astronomical phenomena , human become capable to understand things related directly to his daily life such as agriculture , as an example ,ancient egyptian were able to know when the Nile will overflow just by seeing the The Summer Triangle which is an imaginary triangle drawn on the northern hemisphere’s celestial sphere, with its defining vertices at Altair, Deneb, and Vega, the brightest stars in the three constellations of Aquila, Cygnus, and Lyra, respectively. a lot of examples could be given on how much astronomy infect our lifes ,
without astronomical observation Einstein could not be able to prove his théory about the space-time and how light do not move in straight ligne but it do follow curve in space and without this particular information we would never be able to have GPS or satelite .in addition to those examples related to reality , astronomy is able to open your mind to inspire you with new thoughts , fill you with wonder and magic ( not the magic of fairy tells ) but the magic of nature .
and finally I think the great, late Carl Sagan said it perfectly, “We are a way for the cosmos to know itself.” It is in this that I cannot remember a time that I looked up at the night sky and was not taken aback by the sheer wonder of the cosmos.
