Our Universe is really vast and empty, though a few grains of material dot this cosmic void, since the small dust grains to larger stars. What is the size of these grains of material?
The next possible catastrophe is called Apophis (2004 MN4), in 2004 we discovered a new asteroid 270 m long, updated in January 2013 to 325 meters, which announced the end of the world April 13, 2029.
The first Trojan asteroid of the Earth was discovered in October 2010 by NASA, he accompanied us twirling, for a long time in our walk around the sun. The asteroid 2010TK7 precedes the Earth on its...
Life evolves away glaciations. Life is a chemical process in which living organisms are derived. Matter of life is present on earth and certainly elsewhere in the universe for billions of years...
The hellish journey of the photon. The photon, created in the core of the Sun, transports the light rays to the earth, but it must pass through the radiative zone, convection zone, photosphere, the chromosphere, and finally...
The general public knows the zodiac signs of astrology. The zodiac is the name of the area where the heavens are observed the movements of the Sun and planets. In fact, the ecliptic passes through thirteen constellations but one of them...
Volcanoes at the origin of life. The volcanoes are probably the key to the origins of life on our planet. The volcanoes brought to the surface of the earth, heat, water and a potent cocktail of organic compounds...
Are we alone in the universe? Life thrives in places where even the sun's energy does not penetrate, we see it in the depths of our planet. The chances of discovering life elsewhere, grow every day...
The speed of light and space time. The nature of light falls under the quantum mechanics to which it is both a wave and a particle. The light has a wavelength, which determines the color...
The global warming. The "micro organism" Earth is feverish and all humanity panic, every flood, storm, tsunami and other earthquake pushed the anguish of men...
The life of the abyss is surprising. In the deep ocean, lives a strange world. Even in total darkness and the cold of abysses, life demonstrated great tenacity. Nutrition and reproduction remain...
Generation "oil" At the dawn of a revolution. Most of the world oil formed during very short periods of extreme warming, there are 90 and 150 million years. We consume...
Earth in crisis, the end of a stable world. We have no idea how the world evolves, we must accept to live in ignorance, without certainty because the very meaning of evolution is unpredictable...
The Tardigrade, over-equipped for life on Earth. The tardigrades are able to stop their metabolism and become immortal (state cryptobiosis). To enter cryptobiosis, tardigrades retract their eight legs and...
Radioactivity is a phenomenon that occurs in the nucleus in the deepest of atoms. Radioactive radiation, can come extract electrons from the biological material, if the energy of radioactive particles is greater than Energy...
Nuclear power and radioactive pencils. The main source of radioactivity is natural, but we have not developed senses to detect it. The pellets of uranium dioxide, are stacked in zirconium tubes...
The mystery of matter, where does its mass come from? Without mass particles would travel the speed of light and the universe would be only radiation, there would be nothing solid. If the matter can...
The secrets of gravity. The tissue of space is distended by heavy objects such as planets and stars, and it is this distortion or curvature of space-time, which creates what it feels like gravity...
Fractal geometry has allowed us to understand that nature obeys a simple mathematical law. Can be from the Understanding this concept, translating what we see in nature in mathematical language...
The threat of supervolcanoes. The supervolcanoes have a flat structure and it is difficult to detect. Only after have exploded when the underground magma chamber collapses, which can be seen, the famous caldera of supervolcano...
Little story of the evolution towards the living, starts from nothing, there is 13.8 billion years before, space and time does not exist. The microscopic world and the macroscopic world are gathered in the evolution of the universe...
There is nothing surprising in the fact that there are many more planets than stars in galaxies. It was still necessary find a way to prove it. This is the method of gravitational microlenses that was wisely used...
