After a pretty peaceful beginning of the journey, I suddenly lost the control of my space rocket and I crashed in a flask used for an experience in the constellation Science. I was landing anyway, more or less softly, so I took advantage of it to learn a little in this science's world.
Human wants to find a far related living being in space, a civilized species which he can communicate with, even if it’s a simple life form, without anything else. But while searching like that far away, doesn’t he forget what is under his thumb?
Of course, there are monkeys, who share a big part of our DNA… But they aren’t the only one ! Human species say they’re provided with brain and an amazing thinking ability. Like dolphins, octopuses, or ant’s society… We are not the only ones who have developed a difficult language.
Universe is composed of billions of galaxies. Each one is composed of hundreds billions of stars, and many of them go with planets. Among all these planets, 20% are exoplanets: if life establishes there, it will have more chance to survive… It’s with this idea stuck in the head that scientists tried to prove life presence out of our atmosphere.
Perseverance robot is the result of these researches. It’s a geologist robot created by NASA in July 2020. Perseverance had a journey to Mars in order to take samples. This journey on Mars enables discovering many things… Like liquid water presence on the planet surface. A necessary condition to shelter life…
If we base on the theory that our universe is a very little part of a multiverse (all universes), we can suppose this universes can communicate with others. They are called parallel worlds and could interact with our universe. In any case, that’s what Hugh Everett, physicist, thinks.
At the same time, the physicist Andrei Sakharov supposes universes are mirrors. In order to prove it, he proves that our universe is composed of a few antimatter compared to matter. For him, it needs a second universe in order to rebalance quantities. So, the two mirror worlds are opposite in all way.
Hugh Everett was an American physicist and a mathematician. He was born in 1930 in Washington. He became famous thanks to his several worlds theory. He died in July 1982 in McLean.
Andrai Sakharov was a nuclear physicist, born in 1921 in Moscou. He is famous for his defense of human rights and liberties. He also did scientific works which had an important impact. He received Nobel price of peace in 1975 and died in December 1989.
