The theory of panspermia proposes that life on Earth may have originated from microorganisms coming to the planet in meteorites. Some scientists estimate that some viruses and bacteria also come from outer space.
-Salmonella mutant: an experiment proved that the salmonella-producing bacteria develops much faster and lethally in outer space. In the cultures analyzed, the bacteria mutated 167 genes and produced 73 proteins that were not detectable on Earth.
-Gripe Spanish: the Spanish flu was responsible in 1918 for one of the deadliest pandemics in human history. Astronomer Sir Fred Hoyle said the virus, which causes more than 20 million deaths, entered the planet in a meteorite and is activated periodically by the heat of the Sun.
- The mad cow: Bovine spongiform encephalopathy, which is transmitted to humans through the ingestion of meat, is generated by microorganisms called prions, which have a very particular structure. Scientists in India claim to have found very similar chemical structures in the space dust of some comets analyzed.
-Ebola: this deadly virus could have come to Earth by the meteorite collision. The organism would have mutated for centuries until it was able to affect humans.
-SARS: This deadly respiratory virus, identified in China in 2002, could have reached the planet in the form of space dust. Scientists claim that contamination could have occurred in the Himalayas, where the stratosphere is thinner and more permeable.
