I can imagine those old Greeks watching the skies and trying to find out what were the stars, holding a handful of sand and imagining that it was this elementary piece that consisted everything. I can imagine them looking at the sun and comparing it with the rest of the sky. I can imagine them discussing whether those mathematical analysis confirmed the sphericity of the Earth, commenting to each other (in disguised form) the heliocentric theory could be valid. Occasional restless young man if you could leave the planet, another if the man could not have been always so.
Puedo imaginármelos intentando dar una visión global a su existencia, intentando entender si había partículas elementales, si su planeta sería único, cómo era éste, como era lo que quedaba fuera de éste, si lo podríamos abandonar alguna vez, preguntándose por qué el Sol aparecía por las noches dejando lugar, en muchas ocasiones, a la Luna, y que por qué el Sol iluminaba. Otros averiguando si el alma existía, pero, en caso contrario, ¿cómo podría explicarse humans? Some, more bold, if the existence of gods was necessary ... So true human civilization began, with questions. No matter whether there was an immediate response, the important thing was to find a real solution to the question. One logical explanation that held its own. That civilization began to hatch covers to be irrational to look further. To know what that got married, where is and why it's there. The sense of their existence was no longer eat to live to mate. The direction was to study the chick, the shell and around him. The Greeks gave us some answers, but their number was negligible for the vast amount of questions.
Now, some twenty centuries later, we know some answers to these questions. We know that matter is made, what is. We know what the earth where, how, how it moves and where it is. We know they are the stars and the sun illuminates why. We know why we are glued to the floor. We know that man is nothing special, but a stage of evolution that emerged from the field. It is a distant relative of the bacterium and a close relative of the chimpanzee. But in his background, given the presence of a star, the subject of which he's done. know that our star is comúny not occupy a special place in the galaxy. And we could continue with a number of answers that with effort the species has been acquiring. Too many questions and that makes even feel the force of the mystery that motivates us to investigate. Knowing that God in the most common form is not necessary, indeed, absolutely necessary. Therefore, what surrounds us has a logic understandable that we can understand. Everything has a meaning and we are here.
But we are animals and sometimes seem to make an involution. When the answers is more than ever within our grasp, when at last we can really change a human being in a special animal to unlock the mysteries that have so concerned for thousands of years ... When the answers mark the meaning of our lives are before us, we run into our shells encasing. To give an understanding of nature, the cosmos, the universal order to look at us our navel, to focus our attention on our petty little matter internally. Culture, politics or ilk are worse hobbies that keep society entertaining as a ball to a dog. These are serious things we say and those with spirit eager to understand the mechanics of the universe we sympathize with this poor sick society that has left the way back to the caves.
Greek imagine those longing for answers and I see before me an ignorant society that disdains poor responses to them served on a silver platter. A poor species can still be kind and rich in wisdom, has chosen the path of the machine led by their selfish genes, leading to a slowdown semicaos and scientific advancement. Some poor animals but think they are superior, however, behave like any other. Prefer to believe that mythical explanations for life in a magical aura of ignorance not brave enough to accept reality, no matter how we present.
I doubt that few people can change the opinion of five billion, so those wishing to understand the cosmos, we should go ahead and keep letting us take the burden of others, avoid conflict and seek the maximum development of knowledge as far as possible. Live as rational beings and not burn time with trivial matters. We must be consistent, we have to be an example in which some of the flock can be fixed and leave it. We understand and delight. And then die peacefully quiet with a job well done and time well spent.

But here we were talking about a simple home and small lamp. But what the great light of our great home? The Sun, with a diameter of one million three hundred ninety-two thousand kilometers (1.392 million km, 109 times greater than Earth) inside fuses hydrogen atoms to become helium atoms. There is a difference of mass becomes light energy equation due to Einstein's special relativity. The time it takes the photon to reach the core of our eye is a little more than a million years. Although in reality the time it takes from leaving the Sun until it reaches our eye is about 500 seconds (approx.), about 8 minutes or less. 
Comes from a distant star ...
