Author of quotes: Stephen Hawking

I noticed that even those people who assert that everything is foregone and that nothing can be done about it, look around before crossing the road.

If you don't give up, it matters.

Do not forget at least sometimes to look at the stars.

Artificial intelligence of computers will overtake human intelligence in the next 100 years, and when this happens, you need to make sure that the goals of the computer and the person will coincide, and not go against each other.

The results of our observations support the assumption that the universe arose at a certain point in time. However, the very moment of the beginning of creation, the singularity, does not obey any of the known laws of physics.

Artificial intelligence is terrible for its efficiency and complete lack of empathy for people, especially those whose interests do not coincide with the presets of robots. The main question is who will be engaged in setting such goals and interests - people or machines, which sooner or later will learn to copy themselves. Though for the service of humanity.

The universe is a very cruel place. Stars absorb planets, supernovae proton stars spread deadly radiation throughout space. Black holes collide with each other, and asteroids rush at hundreds of miles per second. It is guaranteed that all these phenomena do not make space very attractive. But it is because of this that we must master it instead of staying on the planet. Unfortunately, an asteroid impact is something we have no protection against. And it won't. The last major collision with the Earth occurred 66 million years ago and caused the disappearance of dinosaurs. And it's going to happen again. This is not some science fiction, but a fact confirmed by the laws of physics and probability.

The laws of science do not distinguish between the direction "forward" and "backward" in time. But there are at least three arrows of time that distinguish the future from the past. This is a thermodynamic arrow, that is, the direction of time in which disorder increases; the psychological arrow is the direction of time in which we remember the past, not the future; the cosmological arrow is the direction of time in which the Universe does not contract, but expands. I have shown that a psychological arrow is practically equivalent to a thermodynamic arrow, so both of them must point in the same direction.

From mistakes and external threats, humanity is able to protect only the alma mater of all knowledge - science that allows you to develop technologies to absorb CO2, reduce the level of energy consumed, destroy an asteroid - whatever. It is possible and necessary to use engineering to create cheap and nutritious products, to combat deadly diseases. The ultimate mission of the next few generations should be the colonization of as many planets and stars in the Universe as possible: after all, who knows what will happen to the Earth and when we will finally get tired of each other. For all of this to happen, we need to wake up, and as quickly as possible. Humanity must rethink how we treat the planet and how we use its resources; to reconsider our relationships with each other and other living beings; get rid of nuclear weapons, end hunger and distribute the world's wealth more equitably. At the end of the day, science education needs to be made available around the world. This will inspire young people to explore the universe, solve problems and engage in research.

We are all different, but we share the same human spirit. Perhaps it is in human nature that we adapt and survive.

Our only chance of long-term survival is not to hide on planet Earth, but to disperse in space.

A black hole is not actually black and not a hole.

The human mind is an amazing thing. He can understand the greatness of the heavens and the complexity of the underlying components of matter. But to the mind to fulfil its potential, needs a spark. The spark of curiosity and wonder.

If you look into every outstanding personality, it is always an outstanding teacher. When each of us thinks that it can make in your life, it is highly likely we will be able to do this thanks to their teachers.
