Extraterresterial Life Exists, Scientist Chandra Wickramasinghe Claims


If a group of scientists are correct, tiny fossils uncovered inside a meteorite found in Sri Lanka in December are proof of extraterrestrial life.

In a detailed paper called "Fossil Diatoms In A New Carbonaceous Meteorite" that is appearing in the Journal of Cosmology, Chandra Wickramasinghe claims to have found strong evidence that life exists throughout the universe.

An electron microscope was used to study the reported remains of a large meteorite (see image below right) that fell near the Sri Lanka village of Polonnaruwa on Dec. 29.

Wickramasinghe is the director of the Buckingham Centre for Astrobiology at the University of Buckingham in the U.K. In December, he and his colleagues found "a microstructure and morphology characteristic of a wide class of terrestrial diatoms." The group concluded that "the presence of structures of this kind in any extraterrestrial setting could be construed as unequivocal proof of biology" -- in other words, proof of life outside of planet Earth.

Wickramasinghe and the late English astronomer Sir Fred Hoyle co-developed a theory known as "panspermia," which suggests that life exists throughout the universe and is distributed by meteoroids and asteroids.

Rock solid proof of alien life? Scientists claim fossilized algae inside meteorite


Fossilized algae recently discovered inside a Sri Lankan meteorite could finally prove the existence of extra-terrestrial life, claim the authors of the new paper.

In a recently published article in the Journal of Cosmology titled “Fossil Diatoms in a New Carbonaceous Meteorite”, scientists from the UK and Sri Lanka claim to have found fossilized algae in a meteorite.

The paper alleges that “microscopic fossilized diatoms were found in the sample,” which fell in Sri Lanka in December last year. The finding, the work suggests is a “strong evidence to support the theory of cometary panspermia.” The theory argues that life across planets is spread by meteorites and asteroids.  Panspermia suggests that life could have existed on another planet and moved to Earth.

The scientists concluded the paper by saying “the presence of structures of this kind in any extra-terrestrial setting could be construed as unequivocal proof of biology.”

Samples from the rock were collected immediately after a large meteorite disintegrated and fell in the village of Araganwila in Sri Lanka on 29 December 2012.

The scientific community, including Prof Francis Thackeray from the Institute of Human Evolution at Wits University welcomed the report as  “very exciting” yet “very controversial”, as samples could have been contaminated on earth, Business Day reports.
