Hoffman is one of about five hundred people who lived through the unique experience of seeing Earth from its orbit. Imagine that being in space, you can pull your hand and completely close our planet – so that all our knowledge, the whole humanity, and every person who has ever lived on Earth, simply disappear. This very clearly shows how vulnerable we are. That is why, according to Hoffman, (more…)
In his book, he cited a number of facts that show how maladjusted people are to life on Earth. According to him, human is the most developed and at the same time the worst-adapted to life on the planet species. Silver notes that humanity is suffering from an abnormal number of chronic diseases, which are not peculiar to any other living being on Earth.
In particular, he said that people with age often suffer from a sore back, because obviously, their species has evolved on a planet with (more…)
For 80 years now we are told that the first self-replicating molecules appeared in the primordial soup in the Earth’s shallow waters, which happened 4 billion years ago. This “soup” was composed of amino-acids, polypeptides, and nitrogenous bases of nucleotides formed as a result of electrical charges, high heat and cosmic radiation.
However, the experiments to replicate similar processes have given mixed results: the basic monomers began to form substances that prevented the expected complexity to exist in this “soup” of polymers.
Later, the problem seemed to have been simplified by the “RNA world” hypothesis, but the probability of spontaneous formation of RNA, which wouldpossess catalytic properties, is very low. It is estimated that four billion years (more…)
The “great minds of the world” estimated the most likely causes that might lead to the end of the world.
According to their calculations, killer robots and cyber-attacks that will cause chaos in communications are the greatest enemies of mankind.
The distinguished scientists of the University of Cambridge, among them Stephen Hawking, launched a study to identify what threatens the modern man.
Professor Robert May of the Center for the Study of Existential Risk of Cambridge, said: “When you know your enemies, you can face them.” Head of the center is Martin Rees who points out that among the greatest enemy of mankind is man himself and not natural phenomena. (more…)
Human civilization is developing very fast. Only five thousand years ago first nodular writing was introduced, and today we have learnt to share terabytes of information at light speed. And the pace of progress is increasing.
Predicting what human impact on our planet may be even a thousand years into the future is almost impossible. However, scientists love to speculate as to what awaits the earth in the future if our civilization suddenly disappears. Let us follow them and envision an unusual situation, for example, what if in XXII century all humans will leave Earth for Alpha Centauri, what is going to happen to our forsaken world? (more…)
