Can we reach and colonize other planets?

Carl Sagan was one of the great scientists, but he was also: celebrity, writer, teacher, skeptic, and freethinker. One of the most influential and committed to scientific dissemination, who from a very young age dreamed of the mysteries of the universe. Now that our society is facing one of the greatest challenges in our history as a species to preserve the balance of the Earth, I would like to share one of the many thoughts that Carl Sagan left us:

Can we venture into space? Will we be able to move worlds, redesign planets, and expand to neighboring star systems? We who cannot even keep our planet plagued by rivalries and hatred in order. That we plunder our natural environment and kill each other out of anger and inattention. A species that until very recently was convinced that the entire universe belonged to it for its own benefit.

I don’t know very well if there is a “we”, with our current customs and our social conventions, who will be out there? If we continue to accumulate power instead of wisdom, we will most likely end up destroying ourselves. Our existence in that distant time requires a change in our institutions and in ourselves. How could I dare to guess the future of the human being in the very long term? That will be I think only a matter of natural selection, if we become even a little more violent, more closed, more ignorant and more selfish than we are, it is more than likely that we have no future.

If you are young, you may see how we step on near Earth asteroids or even Mars during your life. By the time we are ready to settle in other planetary systems, even if they are the closest, we will have changed. The course of so many generations will have changed us, the different circumstances in which we will live will have changed us. We are a very adaptable species.

We will not be the ones who reach Alpha Centauri or other nearby stars, it will be a species very similar to us, but with many of our strengths and very few of our weaknesses, a species marked by its circumstances, more similar to those for which It originally evolved, with more confidence, more foresight, more ability and more prudence. The kind of beings we wanted to represent ourselves in a universe, which we know is full of older, more powerful and very different species.

The enormous distances that separate the stars are providential. That quarantine is dispelled only by those with sufficient self-knowledge and judgment to travel safely from one star to another. Our distant descendants, safely separated on many worlds in the solar system and beyond, will be united by their common heritage, their respect for their home planet, and the knowledge that, despite more life, the only humans in the entire world. universe, come from Earth.

Will we continue to accumulate power or wisdom?

Traveling on tides

The sea, the escape rout that I miss . In these times of coronavirus and quarantine. But, I am lucky to be able to “travel” through the images.Viajando en las mareas





Bee Flower

Or also called “Wasp Orchid” (among other names). We can find it in various places in the Mediterranean such as in meadows, places with bushes, forests with sandstone soils, etc.,.
But, my friend Fran Rubia and me, found a nice little group under a few olive trees.





“Verde que te quiero verde”

If we adjust the look when we pass by a river, ditch or any stretch of water; We can delight in the textures, reflections and colors found there. The common water strider (Gerris lacustris) knows it well and, therefore, almost always lives sailing on the water.


Enjoy the moment

This Christmas I spent several days in the Entinas-Sabinar Nature Area and Reserve (Paraje Natural de Punta Entinas-Sabinar) to see which wintering birds were there. In one of the ponds I always saw around 50 or 60 Waders, so I tried my best to take a good picture of them. But the day I went there I couldn’t have the chance to see them, and the ones that were there were quite dispersed in the different ponds of the surroundings. I didn’t really know what to do, because there wasn’t too much activity and I spent a big amount of time thinking where to place myself. In the end, I ended up in a small pond where I had already seen a group of black-necked grebes (Podiceps nigricollis) since summer.
Times passed and the grebes didn’t come near, I could only take pictures of them with the 600mm, but I wanted them to be nearer. But if I’ve learnt something in photography is not to be impacient, so I decided to stay a little longer. All of a sudden, a western marsh harrier (Circus aeruginosus) dropped sharply a bit further from where I was, and in a few minutes tok flight again to my position. I knew it would fly above me, but when you are laid down you don’t have too much freedom to move and, in that momento, I had to decide whether to try and take the picture probably scaring away the bird, or forget about the picture and enjoy the moment. I decided to go for the second option and the western marsh harrier passed by 2 metres above me beating its wings. A very precious momento that doesn’t happen every day. I don’t know what would have happened if I had tried to take the picture, but what I do know is that in this world where everything is more often accelerated, it is ok to stop and listen and feel the present, without seeking its fast consumption.
Later, nature provided me with the approaching of the grebes, of which I could take a great collection of pictures.
I hope you enjoyed the story and the picture!
