When looking up to the limitless sea of dark with floating bright dots and feeling like an ant in a floating rock, this may cause anxiety, confort, fear, humbleness, lonineless, hope...a true mix of emotions. But if you think again, we're whole universes ourselves: we carry entire populations, trillions of living organisms, many of which exist only to protect you from any possible harm.

Some decades ago, we used to think atoms where the smallest and indivisible thing in existence and, fortuannely, we where wrong when saying that. We keep trying to leave this planet and conquer other celestial bodies, when we acctually haven't even finished to learn from the one we're touching right now. Think again in that sea of dark and now look at your own hand, well, the diference? To REALLY see something in the space everyday(besides the visibles stars) you would need a good telescope and that's far from afordable to everyone(speceally in developing countries like mine), and becoming an astronaut isn't a easy task. Don't get me wrong I'm not here do discourage anyone to becoming a space man walker or to say that microbiology is easy and anyone could do it, the point is if you want for example see the very clearly and closely the digital of your finger, you just need a $10 dolar microscope and that may be already something that can change your perspective from things and the world we live in.
