Journey to the limits of the universe
by Cristiano Galbiati (Writer), Juan González-Castelao Martínez (Translator)
"Understanding dark matter and dark energy will establish new Pillars of Hercules in the centuries to come. Here the history of science is made. And also that of humanity and its perception of itself."
Dark matter is the great enigma of 21st century science. If you ask a physicist, "What remains to be discovered, now that the Higgs boson has also been found?" he will almost certainly answer: "practically everything". Yes, because ordinary matter accounts for only 5 percent of our universe. The rest would consist of dark energy and dark matter, which would account for almost 90 percent of the total mass. For every gram of ordinary matter, there would be, somewhere around us, 9 grams of dark matter. Even so, some scientists claim that it does not exist. Or rather, that there is no need to hypothesize its existence to explain the anomalies observed in the rotation of the Galaxies. Those who reach this conclusion dare to challenge one of the pillars of modern physics: Einstein's general relativity. Cristiano Galbiati, who teaches physics at Princeton and coordinates the DarkSide experiment at Gran Sasso Laboratories, knows that dark matter is one of nature's most mysterious and fascinating secrets, jealously guarded and yet to be deciphered. "If it is true that our Galaxy is immersed in an aura of dark matter," says Galbiati, "the Earth rotating around the Sun, which in turn rotates around the Galactic Center, should be hit by a wind of "dark particles": approximately 100 000 would cross a surface equal to that of a nail every second. So why not try to intercept them?"
In the search for dark matter, in a tight competition, work groups of physicists, astrophysicists, cosmologists, professionals and amateurs, experimentalists and theorists, scientists and philosophers. All driven by the unstoppable ambition to contribute to a fundamental step in the development of science: understanding and defining the nature of dark matter will change the perception of the universe in which we live.
