The Courier Mail newspaper reported that in the episodic documentary "Into the Universe" on Discovery channel, renowned physicist Hawking said that the universe has about 100 billion galaxies, each with several hundred million stars star. In such an immense space, perhaps the earth is not the only celestial body containing life.

"In terms of mathematics, those numbers alone make me think that the existence of extraterrestrial civilization is reasonable. Our challenge is to understand the appearance of creatures other than Hawking said, " Hawking said.

According to Hawking's description, extraterrestrial creatures are quite diverse in appearance. Some creatures own up to 6 feet, but there are also species that only move with two legs. They can eat plants or eat meat.

Stephen Hawking once spoke on a television show in the UK that people should not try to contact creatures from other civilizations, because with a very high level of development, strange creatures can invade the earth and push humanity entered the scene of extinction.

Many fantasy films build an image of extraterrestrial creatures 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.
