Most scientists have no
doubt there are other intelligent beings in the universe, but why
haven't we found them yet?
One possibility, according to a
former NASA scientist is because
extraterrestrial civilizations are living at the bottom a frozen
ocean on a distant water world.
The theory comes from
Alan Stern, who now works at
Southwest Research Institute in
Some may say the theory is far-fetched, but considering we hardly
know what is at the bottom of our oceans on Earth, it is impossible
to reject the probability alien life can exist underwater elsewhere.
Extraterrestrial Civilizations Living Underwater Are Safer
According to Stern there are several benefits of creating
Aliens living underwater would be protected them from exploding
stars, spikes of space radiation or other natural disasters. So,
it's a safe environment.
During a speech at the 2017 Division for Planetary Sciences
some days ago, Stern discussed the
Fermi paradox and elaborated on why
we haven't found aliens when it's so likely that they exist
somewhere in our gigantic universe.
explanations [to this paradox] have been proffered," Stern
"We suggest another - namely that the great majority of worlds
with biology and civilizations are water ocean worlds."
Answer to Fermi’s Paradox in the Prevalence of Ocean Worlds?
Sterns thinks it's likely
alien water worlds can be extremely cold.
This would mean an
underwater extraterrestrial civilization must probably be living
beneath a thick crust of ice that makes it impossible for us to
"Water worlds are
naturally cut off from communication by their interior nature
below a thick roof of ice or rock and ice, therefore do not
easily reveal themselves," he said.
Underwater Beings Resemble Fish?
Many think that alien underwater creatures would resemble fish, but
this doesn't have to be the case.
Dr. Fergus Simpson from the Institute of Cosmos Sciences
at the University of Barcelona used a complex form of maths called

According to Dr. Simpson fish-like aliens are unlikely to be
"The main reason I'm
skeptical about there being lots of intelligent underwater alien
species is that I think it's harder for aquatic creatures
like dolphins to use tools or
build a fire."
Speculating in what
alien species look like can be
funny and who knows what creatures are out there.
Some scientists suggested
aliens can resemble giant jell-fish and there are those who say our
alien neighbors will look like humans.
We really don't know...
