A startling new study from the Harvard-Smithsonian Center for Astrophysics suggest that life on Earth could have started from aliens. The theory known as panspermia also suggests that life on Earth started elsewhere in the cosmos and was brought to the planet by comets and meteorites.
According to The Daily Mail, the theory of panspermia is not new, in fact it was proposed in 1871. However, the theory recently gained popular support from astronomers after they discovered just how much organic compound the universe holds.
The theory provides two explanation how cosmic organic compounds can find their way into Earth. The first is being transported by asteroids, comets and meteorites that manages to penetrate the Earth without completely disintegrating in the atmosphere. The second way is through an advanced race of space aliens exploring the space to discover new worlds.
The scientist leading the research Dr. Henry Lin said, "In our theory clusters of life form, grow, and overlap like bubbles in a pot of boiling water." This model theorize that life came from one living planet and spreads outward in all directions. This model also supports the idea once speculated by Charles Darwin that life started in "some warm little pond."
According to The Mirror, the spread of life from one planet to another is likened by scientists to a form of epidemic-like pattern.
According to New Scientist, to substantial evidence could prove that the idea behind the theory of panspermia is true. Despite this lack of evidence, many scientists still agree that the theory is still plausible.
