Do Aliens really exist ? This discovery may prove it.

Alien organisms may have been carried to Earth on a stream of space dust, scientists have claimed. British researchers said that tiny microbes from other planets may have wafted through the void, allowing them to travel to and from our planet. 

The research once again raises the fascinating possibility that life on Earth arose when tiny bugs arrived here from alien worlds. Some experts believe that alien organisms travel through the universe aboard meteors and comets. This theory is known as panspermia and is exciting because it suggests alien life may be very common.

Now British scientists have given a further boost to the search for extraterrestrial life after studying powerful flows of interplanetary dust that can travel through space at up to 44 miles per second. They calculated that small organisms and ‘bio-particles’ floating high in the atmosphere at an altitude of 93 miles or more could be knocked free of the Earth’s gravity by incoming space dust. Eventually, the tiny organisms could reach other planets in the solar system. Some bacteria, plants and even hardy micro-animals called tardigrades are known to be capable of surviving in space.

The same process could occur in reverse, bringing extraterrestrial bugs to Earth and possibly helping to seed life on the planet, the scientists believe

Study leader Professor Arjun Berera, from the University of Edinburgh’s School of Physics and Astronomy, said: ‘The proposition that space dust collisions could propel organisms over enormous distances between planets raises some exciting prospects of how life and the atmospheres of planets originated. 

‘The streaming of fast space dust is found throughout planetary systems and could be a common factor in proliferating life.’ Scientists recently spotted a planet the same size as Earth which is the ‘the closest known comfortable abode for possible life’ and is just 11 light years away.
