A lot of respectable scientists and writers believed that Earth is hollow inside.
These mysterious bodies of water could even hold lifeforms which are so unusual that some scientists would regard them as aliens. Steve Jacobsen, a researcher at Northwestern University in Illinois, said a part of Earth’s core called the mantle could contain several oceans’ worth of water. Rumors about underground towns appeared for the first time in 1946. The person to launch the rumors was Richard Shaver – writer, journalist and scientist. His incredible story about contacts with aliens living under the ground was published in Amazing Stories Magazine.
