The web appeared the last interview of the famous theoretical physicist, popularizer of science Stephen Hawking, where he tells how he could become immortal and how to save the world's population from global dangers.

American astrophysicist and popularizer of science Neil Degrass Tyson published a full version of one of the last interview with Hawking, where scientists discussed questions about his personal life and the features of scientific activity.

So, in a conversation, Stephen Hawking said that his favorite food is oysters, Pimm's drink (a summer light alcoholic fruit cocktail), and the favorite equation is S = A / 4, which the scientist deduced, thus describing the ratio of the entropy of the black hole to the horizon of it of events. Hawking was asked questions about what he would ask Isaac Newton if he could communicate through time. To which Stephen replied that he would ask the question of whether the solar system is stable and what happens to a star that can not cope with its own gravity? The legendary scientist gave answers to a number of other interesting questions.

Stephen, you've been on a zero gravity simulation. How did it feel?.

- It was wonderful to soar in weightlessness. Without my chair. I could keep doing this forever..

If we develop technology to load the brain into the computer, reach "life after death" or at least "consciousness after death," would you subscribe to it?.

- My body practically does not work because of ALS, getting rid of it would not mean losing to me, it would save me from discomfort. I could become immortal, if only in the form of only the brain, unless someone turns off the computer or he gets infected with a virus.

Everyone would like to know: what existed before the Big Bang?.

- Nothing. According to Einstein's general theory of relativity, time and space form a space-time continuum, not flat, but curved by the matter and energy contained in it. I adapted the Euclidean approach to quantum gravity to describe the beginning of the existence of the universe. In this description, the usual real time is replaced by an imaginary time, which behaves like a fourth dimension of space.

Will we ever be able to travel back in time?.

- We can hope that we could distort the space-time, so that you can travel to the past. But I proved that this is impossible under the condition that the energy density is always nonnegative. Travel back in time is possible, but only for a civilization that will be able to get negative energy, energy "below zero energy vacuum".

You publicly said that you would like humanity to become a multi-planetary species. If there is only one planet, the risks remain high: an asteroid or a deadly virus can destroy the species. But is not it easier to repel asteroid or find a vaccine than terramorfirovat Mars and send back a billion people?.

- Collision with an asteroid is one of the most minimal dangers that we could face. The last collision was about 70 million years ago. Nuclear war, climate change, pollution are serious threats. Of course, it would be impossible to move the entire population of the Earth to a new planet, but if we can organize independent self-sustaining colonies in space, this would guarantee the survival of the human race if something happens to the Earth. Leaving the Earth, we will also get a new perspective, we will look ahead rather than look back. We will unite before a common challenge.

Religion has existed for millennia, long before science. Despite the efforts of modern atheists, she survived. What will be the religion in the future?.

- Religion was an early attempt to answer the questions that we all ask: "Why are we here?", "Where did we come from?". Science now gives better, more consistent answers to these questions. But people will always adhere to religion, because it reassures, and science does not understand or trust it.

Who is your favorite celebrity (not a scientist)?.

- Several years ago I would say: Nelson Mandela. He found a peaceful solution seemingly in impossible conditions. Today there is no one to compare it with someone. And certainly not Donald Trump.

You could not sum up your experience in science, technology, life, formulate a lesson for us.

- We all have to do everything possible in each of the situations that we get into. We should never give up.
