Stephen Hawking is widely known for his theories of gravity and black holes. In addition, the scientist regularly stirs public expectations about the likely destruction of mankind. According to Hawking, people may completely disappear from the face of the Earth, and it has at least three reasons. Let us examine them in detail.
The Three Causes of death for mankind ?


 Artificial Intelligence
Hawking is one of those scientists who share concerns about the creation of a strong artificial intelligence.

"AI Development can put an end to the human race," - said Hawking in the BBC interview.
On Hawking agrees Elon Musk. Director General of SpaceX and Tesla Motors called artificial intelligence, "the biggest threat to our existence."

However, with Hawking and Musk agree not all scientists. Many scientists believe that humanity can not afford to create an artificial intelligence that is comparable in its capabilities with a human.
"We are in the decades from the time when it will be possible to begin to worry. While it is good that the conversation started today ", - said Demis Hassabis (Demis Hassabis), member of the project Google DeepMind.
war
If we do not destroy the machine, we will kill ourselves. At least in certain of Hawking. When scientists asked people what disadvantages he'd most like to change, Hawking said:
"The main human weakness - a propensity for aggression. Once, at the dawn of humanity, the biological mechanism played into our hands. Aggression helps to get more food, territory or partners for procreation. But now it is the quality threatens to kill us all. For example, a nuclear war could easily destroy civilization and the human race. "
When asked what the character of the people should be more scientist said that we lack of empathy - the ability to empathize.
According to Hawking, space exploration is necessary for the survival of mankind.
"Space will insure us from death in the world. We need to colonize other planets, "- sure scientist.
alien life
In 2010, Hawking suggested that if extraterrestrial intelligent life exists, it is unlikely to be friendly to people. 
"If they ever fly, humans will be in the position of the Indians after landing on the American continent Christopher Columbus", - said the scientist in his show on the Discovery Channel.
Aliens may be nomads who colonize all met on the way of the world.
"Every planet found they can use as a source of material for the construction of new spacecraft," - suggested Hawking.

A new tricorder of the Stanford University can be used to detect cancer at an early stage.
New tricorder can detect cancer at an early stage !
The tricorder makes use of microwaves. These microwaves travel through the body, and, for example, a tumor may heat a thousandth of a degree. This is still well within safety margins. Owing to this heating the tumor puts out, whereby ultrasonic waves are being produced. The tricorder captures these waves, causing the exact location of the tumor can be determined. This is done without touching the body, such as an echo

 Another five years of future music

 Although the scientists in their experiment used a piece of meat like material, they hope in the future to test the tricorder on people. "We have been working for about two years at this tricorder," says researcher Khuri-Yakub of Stanford University. "The device is still in an early stage, but we are convinced that the tricorder over five to fifteen years is available."
Tumor ultrasonic hotspot is

 a tumor creates new blood vessels to keep growing. These blood vessels absorb heat in a different manner than the surrounding tissue, causing tumors to be visible as ultrasonic 'hotspots'. The big advantage of a tricoder is that such a device is cheaper and handier than an MRI or CT scan. In addition, micro waves safer than X-rays.
Is the 'fresh' fresh carpaccio really?

 At present, more universities at a tricorder. Researchers at Tel Aviv University have created a device, which consists of a hyper-spectral camera and makes use of image processing software. This offers many possibilities. Soon you can scan with such a camera or the "fresh" carpaccio is really fresh. And if you drink a nice glass of wine on the terrace, the device can reveal from which region the wine comes.

As follows from the article on iflscience.com, one of the participants of the program "to Mars one way" (Mars One) opposed the project, calling it a real scam. After filling in the application (made more out of curiosity), a former NASA researcher Joseph Roche, became one of the 100 finalists admitted to the flight to Mars.
The "Mars one way" may be a scam !




In an interview, Joseph pointed to the many problems with the project, ranging from inaccurate data in the media (it was only in 2761 instead of the 200,000 applicants) to the problems of a psychological or psychometric testing program participants. Some of the leading contenders have earned their place simply by paying money for it.

"When you join as a candidate in the program" on Mars at one end ", that happens automatically after filing, you start to get points," explains Roche."You get points in every round of the selection process, the only way to get more points, is to buy goods from the" Mars One "or to donate money to them." And if you get the money from the media for interviews, the organization would like to get 75 percent of your income. As a result, most applicants are those who are brought into the project more money.

Until now, everything that Joseph did was fill out a form downloaded video, passed a medical examination and a quick test on Skype, and all ... Although the final adoption of the ranks of its potential 100 members of the mission, Joseph Roche has not yet met anyone from the project "Mars at one end."Previously planned multi-day interview, for some unknown reason, have been canceled.

There are other bad signs for the "Mars at one end." For example, the creation of a spacecraft project organizers hoped to earn 6 billion. Dollars on a reality TV show that has not happened yet. In addition, a former adviser to the project, a theoretical physicist Gerard Hooft thinks realistic launch date not 10, but only after 100 years.

General Director of the Program "on Mars in one end of the" Bas Lansdorp gave a press interview in which he called the statements of Joseph Roche untrue. For example, he argues that part of the unsuccessful candidates never made any donations. According to him, in fact it was 200 000 enrolled candidates, and that criticism is welcome because it helps to improve the training mission.

The next step, he said, will be conducted a more thorough selection of candidates for their reaction to the team and individual challenges. It is planned to transfer talks with other companies regarding the construction of spacecraft, as the delay in delivery of the settlers on Mars is unacceptable.
