According to the scientist, aliens resemble a big jellyfish that dangles buoyancy bags similar to onion to keep itself at great height. She adds that with light pulses, these creates communicate with each other.
It is known that a person lives based on carbon and that he needs water in order to live. However, this scientist undermines that conventional wisdom as she considers life forms that are based on silicon, which has the same chemical similarities with carbon. What is more interesting is that silicon is also found in the universe, contributing to the idea that aliens’ life may be based on silicon.
Moreover, the British scientist maintains that humans and aliens live in different environment. Because the atmosphere is damped with oxygen and is lethally corrosive, Earth may suffocate extraterrestrials and eventually kill them. Equally, humans are not capable of living in the outer space.
