Underwater Extraterrestrial Civilizations Could Be Living On Other Worlds – Former NASA Scientist Says

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 the Southwest Research Institute in Texas.

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.

According to Stern there are several benefits of creating underwater habitats.

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.

“Many possible explanations [to this paradox] have been proffered,” Stern wrote.

“We suggest another — namely that the great majority of worlds with biology and civilizations are water 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 contact them.

“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.

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 Bayesian probability to predict the surface of most planets is likely to more than 90 per cent covered in water.

According to Dr. Simpson fish-like aliens are unlikely to be very advanced.

“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 advanced 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.
