....The second thing that God did, as the Bible saids, is the Ligth.
So familiar for us and, some time, so estrange...it fills all the universe
If the Sun did not exists there were not ligth to warm up the Earth. Our planet should be a freezed planet.... to the amazing temperature of minus two hundred and seventy celsius degrees, almost the zero kelvin degrees, almost the absolutely quiet, nothing on the earth moves, because it has not strenth to do it.
The amount of ligth that arrives to the Earth is the just to convert this planet in a orchard...
...regardless on some places could be a little bit excessive and in another a little bit short, for example in the poles, where there are six months every year into the nigth...
A little thousands of years ago the man began to use the fire and the ligth, until then we lived almost as wild animals....
If our Sun don´t exists...
....from the earth, in absolutely nigth, we should see an amazing sky...
....Orion nebula. ( I did this photo)...
...M33 Galaxy, i did this photo, too (with a very lowly equipment, web cam coupled to an 67mm photo objetive).
...and infinite stars, all of them belong to our own galaxy...thats should be the unique heat source out of our planet...cold stelar ligths...
...that, on not exists the atmosphere, on been the Earth under so low temperature, should bright very beauty in the sky.
NOTE: ligth travel to incredible speed of 300.000 Km/s and takes one second and a half on arrive from here to the Moon... takes eigth minutes on arrive from the Sun to the Earth....takes four years and a half on arrive to the nearest star, Alfa centauro...fourty thousands years on arrive to the center of our own galaxy....more than two million of years to arrive to the nearest galaxy, Andromeda...and on arrive to the farest place of the known universe more then five thousand millions of years...
Thanks to the fact that the ligth don´t arrives instantaneusly to any place, all the objets we can see in the sky are as they were many tyme ago, we see them like they were when the ligth leave then, not like they are in this moment. We see the Sun like its was eigth minuts ago, we see Andromeda like it was two million years ago...them, a strange thing, when we look to the stars seems that they are there..but not, they are in another place, all the stars are moved on its own movement for the time that its ligth takes to arrive to us, been imposible know exactely how the universe loks like realy in any particular moment...because all that we see is in the past,and convert our universe in a really chaos.
It´s not amazing?...
