People should not contact extraterrestrial beings

Physical prince Stephen Hawking warns that extraterrestrial creatures may exist but humanity should not seek to contact them, because the consequences will be disastrous for us.

'If strange creatures visit the Earth, the consequences may be the same as when Columbus found America, which meant pushing indigenous peoples into perpetual disaster,' AFP quoted Hawking astrophysicist on a program. TV in the UK yesterday.

Hawking thinks that highly developed extraterrestrial creatures can invade and dominate the planets they discover.

Referring to the viability of an extraterrestrial civilization, Hawking asserts there is nothing absurd when we talk about 'aliens'.

'Our real challenge is to find out how they look , ' he said.

In many fantasy films, extraterrestrial creatures are shaped like giant squid capable of clinging to cliffs thanks to dozens of tentacles. But in many other works, they look almost like humans, with big eyes and blue skin.

Humans have repeatedly sought to communicate with other civilizations in the universe. In 2008, the US Space Agency (NASA) broadcast the Beatles song "Across the Universe" into space to send a message of peace to extraterrestrial creatures.

Before that, in 1972 and 1973, the US also in turn launched two ships carrying the image of a naked man and a woman on the universe. In addition, the two ships also carry symbols and symbols to help aliens know the position of the earth and the sun. In 1977 the US launched two Voyager 1 and Voyager 2 ships. Each ship carried a disk of images and sounds on the earth.

Stephen Hawking (born 1942) is considered the theoretical physicist of the world for decades. He is known for his work on black holes in the universe. Hawking also attempted to pursue the goal of finding a 'unified theory' to resolve the conflicts between Albert Einstein's theory of relativity and quantum theory.

At the age of 21, he was diagnosed with muscular atrophic sclerosis (a type of neuronal decline that controls movement). Experts say only about 5% of people with this disease live more than 10 years. For many years Hawking was almost completely paralyzed. He communicates through a speech synthesis device attached to the computer. Whenever he needed to speak, he typed the word into the computer.
