New Age – New Solution

In each era, people in their dreams solved the problem of contacts with aliens, based on the technology of their time. Until the 18th century, people believed that the energy of muscles, their own and domestic animals would be enough to fly to the stars. And therefore, even fantasizing, the only thing they could offer was just a crew harnessed … to a flock of birds. Our distant ancestors did not know that the air would end immediately, when you “fly away from home”. They did not even imagine the enormous distances separating us from the moon and planets, not to mention the distances to the stars. Then, having measured these distances and having learned that almost empty, airless space divides celestial bodies, they began to dream at least of mutual signaling.
In the XIX century, just a hundred years ago, everyone seriously believed in the existence of Martians. And then, quite seriously, scientists put forward assumptions about the optical connection with them. The mathematician Karl Gauss proposed cutting a triangle in the Siberian forests a multimeter in the form of a triangle and planting it with Continue reading

A new level of evolution

Millions more years pass by. Nature “found” the best amino acid sequences in the chains of polypeptides – protein molecules appeared – the future bricks of living organisms. Replication has become more sophisticated and improved. The matrix is ​​no longer a mechanical form, but a conventional, chemical “record” of the order of amino acids in a protein molecule. Record in the form of a portable chain of special molecules – nucleotides. The evolution of matter rises to a new level. Long, bizarrely curved strands of different protein molecules cling to each other and gradually assemble. First into small lumps, then into larger lumps that look like tangles or drops. Molecules that are closely in contact in a lump have Continue reading

Why exactly the earth?

In the meantime, about the Earth, perfectly prepared to become our cradle. We were lucky. On earth, several favorable circumstances for life coincided. Not every star becomes a Sun surrounded by planets. Should the nebula rotate more slowly, centrifugal force would not have arisen, fragments would not come off from the central clot, planets would not have arisen. And such a lonely “childless” star would swim in a black abyss, barrenly wasting its heat and light … Not every star that gave birth to planets could create conditions suitable for the birth of life on them. It takes a lot of time, billions of years, for the origin and development of life. All this time the star should burn evenly, calmly, equally. Then the conditions on the planet will be constant – and life will be able to adapt to them. But the stars are far from being not all as calm as our Sun. Young stars sometimes flare up. A wave of incinerating heat hits the surrounding planets, burning, evaporating everything Continue reading
