If you are used to watching science fiction movies which depict the arrival of extraterrestrials on earth in hovering spacecrafts, it is time to unlearn all that. A new scientific theory states that aliens may be arriving on earth on meteors and we may be oblivious to their arrival. Researchers have now published a plan detailing how to detect such phenomena. Panspermia, a fringe theory, suggests that alien life could spread from one planet to another by hitching rides on meteors. With around 5,000 exoplanets identified beyond our solar system, it’s speculated that these distant worlds offer the best chances for harbouring life forms different from our own, which might, if they exist, utilise meteor transportation to move between planets.
The biggest challenge may be identifying these life forms which have travelled on meteors. Contrary to the humanoid forms depicted in science fiction movies, aliens may look completely different from the carbon based lifeforms on earth. New research however, might help us detect alien life, even if we don’t know what we’re looking for, reports Live Science.
Two scientists have created a roadmap focusing not on the appearance of alien life, but on its potential impact on Earth. Of utmost importance, alien life might possess the capability to disrupt Earth’s natural equilibrium as they try to terraform our planet to make its atmospheric conditions similar to their home planet.
Researchers can assess this by conducting a statistical analysis that examines a solitary planet, distinct from a group of planets with comparable attributes. If these individual planets exhibit similarities to those within the cluster, it suggests that alien life has potentially visited and initiated colonisation, or at the very least, unusual occurrences are taking place in space. This approach also facilitates the identification of potentially novel life forms, without presuming any specifics about the workings or functionalities of such life forms.
This research is yet to be peer reviewed. The research has its limitations because its research requires a large amount of information on exoplanets. NASA has confirmed that there are at least 5,000 identified exoplanets, and this number is constantly growing.
