The galactic message | Science



Astrophysicist Carl Sagan He believed in God in the scientific way, that is, as the set of physical laws that dominate the universe. Therefore, praying to the law of gravity, or the orbital square of the planets, was always nonsense. As much as praying to celestial mechanics no matter how much its name is evocative.

To many people, his series Cosmos It has helped us understand the original explosion that accelerated life in the universe. The series was given on television during the summer of 1982, when the color had not yet reached the screens of many houses and there were only two channels. With the aforementioned series, Carl Sagan would become one more member of our families, just as Commander Cousteau and the ill-fated Felix Rodriguez de la Fuente were already.

In addition to doing it on television, Carl Sagan he also disclosed his studies -or prayers- in the form of a book. We highlight titles like The Dragons of Eden (Planet), where Sagan reconstructs the evolution of the human being from the development of intelligence, or that other book composed of three scientific figures such as Paul Broca, nineteenth-century French neurologist, Robert Goddard, pioneer in rocket engineering , and Albert Einstein. The book is titled Broca’s brain (Planet).

Between some things and others, Sagan had time to write a novel titled Contact (recently reissued by Nova). It is an exciting story whose main theme is the existence of life in other worlds. Ellie Arroway, its protagonist, is a nod to Jill Tarter, an American scientist who was director of SETI, an institute dedicated to the search for extraterrestrial intelligence.

‘Contact’ tells us the story of a woman who struggles to make a place in the scientific field; world where misogyny dominates. On the other hand, it leads us to understand that we are not alone in the universe

On the one hand, the novel tells us the story of a woman struggling to make a place in the scientific field; world where misogyny dominates. On the other hand, it leads us to understand that we are not alone in the universe.

It should be noted that life on other planets was a frequent topic in Sagan’s studies. So much so that, when the time came, he managed to achieve closest to the message of a bottle thrown into interstellar space. To do this, he designed some metal plates with his wife, artist Linda Salzman and his friend, astronomer Frank Drake.

Such plates were added to the space probes Pioneer 10 Y Pioneer 11, which would be released in the early seventies in order to transmit images from Jupiter and Saturn. Each of the plates had been engraved with decipherable figures for any being with sufficient scientific knowledge. They indicated our position in the universe, as well as our physical appearance.

The report of both space probes has been as follows:

Hopefully some extraterrestrial culture meets the plates in the space probes and deciphers them

Probe Pioneer 10 it was launched on March 2, 1972, reaching Jupiter in December 1973. In June 1983 it crossed the orbit of Neptune and in early 2003 its signal was lost, while the space probe Pioneer 11 It was launched on April 5, 1973, reaching Saturn on September 1, 1979, detecting additional rings on the giant planet. At the end of 1995 he would end his mission.

Hopefully some extraterrestrial culture meets the plates and deciphers them. If so, we would have to thank Carl Sagan for showing the universe that communicating with God is only possible by doing it in the same scientific language.

The stone ax it’s a section where Montero Glez, with a will to prose, it exercises its particular siege to scientific reality to manifest that science and art are complementary forms of knowledge.
