Astrobiologist Says We've Discovered Proof Aliens Are Seeding New Life on Earth With Space Bacteria
One theory, called "panspermia," hypothesizes that extraterrestrial microorganisms lying dormant on the surface of comets or meteors crashed into Earth billions of years ago and kickstarted the development of life. A related theory, called "directed panspermia," poses the idea that an alien civilization could seed planets with life by purposefully sending objects containing bacteria—and that's what Dr. Milton Wainwright claims to have found.
While collecting dust and other particles in the atmosphere with a balloon floating at around 84,000 feet, Wainwright's sampler was hit by a tiny metal ball, apparently composed of titanium and vanadium.
The ball was about the width of a human hair and contained a "gooey" biological substance inside. In addition, the ball seemed to be covered in a "fungus-like knitted mat-like covering," and made a small impact crater where it hit the sampler, suggesting that it was traveling at high speed.
Wainwright has claimed that this tiny ball could be evidence that panspermia is possible, and that its source may be an extraterrestrial civilization. However, he admits that there's almost no way to prove this claim: "Unless of course, we can find details of the civilization that is supposed to have sent it in this respect it is probably an unprovable theory."
Wainwright published his findings in the Journal of Cosmology, but the article has apparently been removed.
This isn't the first time Wainwright has written about microbes arriving on Earth from space, or about panspermia—he previously published a paper in the Journal with the title "Are Microbes Currently Arriving to Earth from Space?"
The Journal itself should be viewed with some skepticism, however—it has been called out in the past for publishing pseudo-scientific and conspiracy claims, including that NASA, Nature Magazine, and Science Magazine are working together to suppress their research.
