Scientists: Alien Bugs May Have Been Transported to Earth


According to new research, aliens might have been carried to Earth on space dust.

Scientists have said that bugs might have flown across the universe and onto Earth. And bugs from that are from our own planet might have made the same journey, flying off of Earth and onto other planets that is elsewhere in the galaxy.

The said theory could even help explain how life started here, implying that it was carried from elsewhere in space then flourished on Earth.

That is according to British scientists who have investigated regarding powerful flows of interplanetary dust that are able to travel through space at a maximum of 70 km (43.75 mph) per second.

The scientists calculated that small bio-particles that are floating high in the atmosphere at an altitude of 93 miles (150 km) or more could be knocked free of the gravity of Earth by incoming space dust.

Eventually, the tiny organisms could be able to reach other planets in the solar system.

Some plants, bacteria, and even hardy micro-animals that are called tardigrades are known to be capable of surviving in space.

The scientists believe that the same process could happen in reverse, transporting extraterrestrial bugs to our plantet and possibly helping to seed life on the planet.

The study leader of the University of Edinburgh’s School of Physics and Astronomy, Professor Arjun Berera, stated: “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 have previously considered the possibility of impacting comets and asteroids importing life, or the raw ingredients of life, to Earth.

The new research that was published in the journal Astrobiology was partly-funded by the Science and Technology Facilities Council.
