Light and Dark in the Universe



This picture is a NASA/ESA (European Space Agency) collaboration, it was tooked by Hubble space telescope and published on NASA's website on August 29, 2014.

It depicts various cosmic phenomena like a star formation or a dark nebulae.

For sake of honesty, I really don't know almost anything of cosmology (isn't a synonym of astrology, so, get out you Pedro Engel fanatics), I think it's really interesting to understand it or talk about Universe phenomena like redshifting, light years and physics like Interstellar do(a movie of Christopher Nolan about, well, interstellar travel). Instead, I like this photo so much because it remembers, at least to me, that in Universe, or, Observable Universe (because we know so little about what it's beyond what we can observe) it's darkness what prevailes. In my opinion, we should take a lesson of the predominant nothingness or darkness in the cosmos. 

We humans tend to judge light like a good or positive thing and dark in the other way. Why is that? may be, cultures in a ubiquitous way (apologies to anthropologist if I'm wrong. If that's the case, please correct me with passion) associate what they don't know - that thing hidden in the shadows. A robber in a city, a savage animal in the nature - with fear. The uncertainty of being in danger, exposed to something evil, or both. I know that someone could argue that, sometimes people fear the light, fear what is known, and that's a really good counter-argument, perhaps so good that I'd lose the discussion.

So, to make my point about that ''lesson'' I will say that light is momentary, a spark condemned to die. If the major theories of physics are right, the Universe will die and the darkness prior to Universe will reign again. What I mean with all of this, is that we should start to appreciate darkness, like the beauty in this picture. Light can't exist if there is no dark to contrast, at the same time, darkness has a lot to show us. If I follow my previous analogy, we should understand that we can't know everything, is good to be in the shadows, in the uncertainty. It's good to expect "dark" things too, in this life, a lot of things will go bad and really really bad (but good too, there is light). We should understand that the fear of the unknown is almost every time, a share experience with other humans, and in that point, we should be more empathic, and understand the fears of others, to be understand.
What is a stranger if not a shadow when we see at his mind?
Don't confuse it with the apparent light that is guess what is in his mind, specially when we guess based on prejudices.

There's no dark side of the moon
Matter of fact, it's all dark
