They discover that the dark side of the Moon was visible from the Earth
The reason by that from here, from the Earth, always we see the same face of the Moon is that our satellite exactly takes the same time in giving a return on itself that in carrying out a rotation around our planet. For that reason, the face hides of the Moon could not be seen until, in 1959, Moon 3 was photographed for the first time by the Soviet sounding. And no human being could contemplate it directly until the astronauts of encircled it to the NASA for the first time on board Apolo 8 in 1968.
But the things could always thus not be. In fact, a computer science simulation realised by Mark Wieczorek and Matthieu Him Feuvre, of the Institute for the Terrestrial Physics of Paris, aims seriously at the possibility that, it does thousands of million years, the situation was exactly the opposite: it was indeed the dark side of the Moon the one that aimed directly towards the Earth.
Later, the impact of a great asteroid gave the return literally him it left and it in the position that occupies at the moment. In order to reach that conclusion, Wieczorek and It Feuvre have studied the relative ages and the distribution of 46 lunar craters of impact. According to its observations, the hemisphere the west of the Moon, as it is seen from the Earth, shows until a 30% more of craters than the hemisphere this.
This is thus because the hemisphere the west always lays for the same direction in which the Moon moves. And that causes that it has more possibilities of taking hits, just as is more probable that more mosquitos against the front part hit that against the back of a car in movement.
Nevertheless, when comparing the age of craters, the scientists were with the surprise that, in the past, it was the face this, and not it the west, the one that took more hits. And that means that at some time that was the front part of the car.
The explanation is compatible with the idea that, at some time of the past, it makes about 3,900 million years, the impact of a great asteroid caused that the Moon, literally, occurred the return. Thing that did in a period that the investigators base in tens of thousands of years.
To those who this idea seems incredible, it is enough to remember that the same formation of the Moon must as large as to the impact against the Earth of an object Mars. When the mammoth encounter took place, the rubbish and the rest sent to the space were united until forming our satellite, as it shows the video under these lines. The idea, that it seemed a madness at the beginning of the seventy, when it was formulated, was proven years later.
VERY INTERESTING!
But, I have a doubt
That there is in the hidden face of the moon?
Thank you very much to that they podrian to respond this very interesting question to me.
