Just at the time that the Nasa reports that the chance of life on the Saturnusmaan Enceladus significantly increased (DS, June 28), researchers from Oxford in the soup spit: ‘Alien life, forget it’.
There are around two thousand billion galaxies in the universe – a few hundred million, we will look not – and each of those galaxies has, what shall we say, some billions of stars …
There are around two thousand billion galaxies in the universe – a few hundred million, we will look not – and each of those galaxies has, what shall we say, some billions of stars. We’re not going to argue about a few zeros more or less, because the conclusion remains the same: there are many, very many. It has to be strange if not a few earth-like planets results in, life included. Right?
We are going to give you is not to contradict, on the contrary, we think along with you. Because, so said the famous physicist Enrico Fermi is already more than half a century ago, if we are reasoning extension, we come inevitably to the question: Where are they? If the universe is full of life, why have we not already long signals from captured or visitors? And no, ufos do not count, who are, by definition, unknown.
We quickly impress
Researchers of the ” Future of Humanity Institute’ of the university of Oxford have everything put on a list: what do we know about the number of stars, the chance that those planets to count, the chance that water as a liquid, the chance that such a planet spontaneously life (there we have one example, but a is not), the probability of that life is intelligent is, the probability that it is not enough to itself, and will be in contact with the rest of the universe, the probability that the lifetime of that civilization overlaps with ours (if they are already extinct, we can’t make contact).
Some of those opportunities would be very small. We have only seventy years, the atomic bomb, and so we can not yet say much about the chance that an advanced civilization blows himself up, but we are there in that short period already a couple of times where very close.
We let us quickly impressed by the vast numbers of stars, as they say in Oxford. But if we also have the uncertainty in those other factors into account – and you have that all together multiply – ‘then we find a substantial probability that there is no other intelligent life in the observable universe is. That they write in an article that they have submitted in the reputed journal Proceedings of the Royal Society, but that there is still not accepted. In the meantime they have it already posted on a well-known website for even non-accepted texts, arXiv.
Exactly because there is a large uncertainty sits on a number of factors, estimate the chance that we only have somewhere between 39 and 85 percent. So you have still the right to your own opinion.
Chance of alien invasion
Elon Musk, boss of, among other space SpaceX, believes that we urgently need Mars to colonize, so that humanity its eggs no longer in one basket – one planet – explains. An invasion by an alien civilization is one of the risks that we can therefore decrease.
But, useful as he is, has Musk, the research from Oxford immediately seized. The chance of an alien invasion is just a lot smaller. But, says Musk, if we are alone it is even more urgent for us to distribute. Otherwise would with us the only intelligence in the universe from extinction.
Or are the aliens already among us? Researchers from the University of Adelaide in Australia have ordered a new wespensoort Dolichogenidae xenomorph baptized. Because of its cruel way of surprising them so very much was reminiscent of the way of life of the monster from the movie Alien (which breaks at a certain moment from the chest of his victim to the outside).
Or we have a colleague of Enrico Fermi, believe, the Hungarian physicist Leo Szilard? “They are already among us, and they call themselves Hungarians,” he said. The Hungarian language is an island within Europe, not related to any other Indo-European language. Where is she coming from? And how about, by the way, Basques, and Finns?
